Transcript
- 0:00David Kingham: In a lot of, um, publicly funded programs, you have the big risk of, um, sunk cost argument.
- 0:08David Kingham: You know, we spent 30 million pounds on this.
- 0:11David Kingham: We have to proceed now.
- 0:13David Kingham: We never got into any, any of that sort of thinking.
- 0:18David Kingham: Uh, some of our very early shareholders said, you know, never take a decision to push on if the evidence doesn't support it.
- 0:29David Kingham: Um, and so we cut, you know, we cut a few things, learned fast, forced ourselves to do things with.
- 0:41David Kingham: Modest resources.
- 0:43Chris Reichhelm: Welcome to the Lab to Market Leadership podcast.
- 0:46Chris Reichhelm: Too many advanced science and engineering companies fail to deliver their innovations from the lab to the market.
- 0:53Chris Reichhelm: We are on a mission to change that.
- 0:55Chris Reichhelm: My name is Chris Reichhelm, and I'm the founder and CEO of Deep Tech leaders.
- 1:00Chris Reichhelm: Each week we speak with some of the world's leading entrepreneurs, investors, corporates, and policy makers about what it takes to succeed on the lab to market journey.
- 1:10Chris Reichhelm: Join us.
- 1:12Chris Reichhelm: Deep Tech is often associated with moonshot technology programs, and fewer programs can be considered more moonshot than nuclear fusion for years.
- 1:23Chris Reichhelm: It's always been one of those things that's 30 years away, but is it still with all of the development and all of the technology and all of the investment happening into fusion, are we getting closer?
- 1:37Chris Reichhelm: To help me answer this, I'm joined by Dr. David Kingham.
- 1:40Chris Reichhelm: The founder and original CEO of a company called Tokamak Energy.
- 1:45Chris Reichhelm: Tokamak could be one of the companies that helps us realize the benefits of nuclear fusion by the development of something called a spherical tokamak.
- 1:54Chris Reichhelm: If you don't know what that is, that's okay.
- 1:56Chris Reichhelm: I promise you'll find out with David.
- 1:59Chris Reichhelm: Today, I want to get into their lab to market journey.
- 2:02Chris Reichhelm: I wanna understand the types of milestones that have guided them from science Project is something more resembling a business.
- 2:09Chris Reichhelm: I wanna understand the skills, the experience, and the talents required to do really big things, things at the scale of a new form of energy generation.
- 2:20Chris Reichhelm: This is gonna be a great show.
- 2:22Chris Reichhelm: I hope you enjoy it.
- 2:23Chris Reichhelm: Let's get into it.
- 2:28Chris Reichhelm: David Kingham, thank you so much for joining me.
- 2:31David Kingham: Thanks, Chris.
- 2:32David Kingham: It's a pleasure to be with you today.
- 2:35Chris Reichhelm: As a founder and as a chief executive of the, the first Chief Executive of Tokamak Energy, I am thrilled to have you on the show and to learn more about the evolution of what has become.
- 2:52Chris Reichhelm: I think, uh, and it's no exaggeration to say this, one of the leading nuclear fusion companies in the world today, um, uh, promoting the spherical Tokamak design and, uh, it would be great to understand the lab to market journey that Tokamak has been on.
- 3:11Chris Reichhelm: And so as you've been around for this journey, uh, journey, I feel very fortunate to have you te take us back, if you would, to the beginning and you know Sure.
- 3:23Chris Reichhelm: What, you know, where did all of this start?
- 3:28David Kingham: Yes, it's been quite a long journey so far, and there's a few more miles to go.
- 3:34David Kingham: Um, so 15 years ago I teamed up with two scientists from the UK Government Research Laboratory, um, working on Fusion.
- 3:46David Kingham: And it would be fair to say they were frustrated by the slow progress, particularly of very large, um, government fusion programs.
- 3:57David Kingham: Um, in and now these two guys, Alan Sykes and Mikhail Gryaznevich had had fantastic success in the 1990s with a small spherical Tokamak.
- 4:11David Kingham: It had achieved record results, um, and was recognized, um, by US and UK government as being a very promising route to commercial fusion energy.
- 4:26David Kingham: But it was kind of lost in the noise behind the excitement of the Jet Tokamak at Culham, which achieved 16 megawatts of fusion power.
- 4:39David Kingham: So there was this little high performance device and a fantastic big 16 megawatt, um, fusion reactor.
- 4:49David Kingham: Uh, and then the whole world decided that, um, scaling up the jet tokamak, the one that achieved its 16 megawatts, scaling that up was the right way to go.
- 5:03David Kingham: And you know, we didn't all think that.
- 5:05David Kingham: Some of us thought I had to be a, uh, an alternative way to go, which might be faster and, um, more commercially relevant.
- 5:16Chris Reichhelm: Mm-hmm.
- 5:17Chris Reichhelm: And in those early days, was it just the three of you or were you starting to pull together the early foundation for a team?
- 5:25Chris Reichhelm: Beyond just the founders, really,
- 5:27David Kingham: just, yeah, just the three of us took, you know, a few helpers at the very early stage, and then some investors started to come in.
- 5:39David Kingham: Um, we were very fortunate with early investors.
- 5:43David Kingham: Um, we had, um, what, what is now the UK Science and Innovation Seed Fund, um, that's designed to help spin out technologies from government labs.
- 5:56David Kingham: Um, we had an investment from Oxford Instruments, uh, uh, superconducting magnet business, um, and from Sir Martin and Audrey Wood, um, who were the founders of Oxford Instruments, who really had a passion for getting small businesses started.
- 6:16David Kingham: So the, the, they were very much part of the team early on.
- 6:21Chris Reichhelm: And, and what is the focus about developing or scaling up that token Mac?
- 6:28David Kingham: Um, the initial focus was initially we thought fusion energy is, is too much for us to attempt.
- 6:39David Kingham: Um, and we should look at the spherical Tokamak as a scientific instrument with high performance plasmas.
- 6:48David Kingham: Mm-hmm.
- 6:48David Kingham: And basically wait until someone else comes up with some other innovation.
- 6:55David Kingham: Um, and we had an internal debate at the time around high temperature superconductors and, uh, chief scientist Mikhail Gryaznevichvi was, you know, saying, this has to happen.
- 7:08David Kingham: We, we need this new material.
- 7:12David Kingham: And I kept saying, well, it, that's fine, but it's not, um, manufactured as a.
- 7:19David Kingham: Usable engineering material yet.
- 7:24David Kingham: Um, and, you know, but he was, he was, he was right.
- 7:29David Kingham: We had to have it and I was right at the time.
- 7:33David Kingham: It wasn't ready.
- 7:34David Kingham: Yeah.
- 7:35David Kingham: But, uh, 2011, a guy at Oxford Instruments told us that they'd had a new batch of high temperature superconductor, uh, from a company called Superpower in, in the U.S. and that it was ready to use to make magnets.
- 7:53David Kingham: It was good enough.
- 7:55David Kingham: Um, so we thought, well, we better try it.
- 8:00David Kingham: So at that stage, Mikhail phoned up his friends in Prague and said, can I borrow your tokamak, uh, for the summer to do an experiment?
- 8:11David Kingham: And, I mean, Tokamak are not very common devices, so this is one big ask.
- 8:17David Kingham: So they said, um, well, you can, you can borrow it for two weeks.
- 8:23David Kingham: Um, at which stage we thought, can you really put a magnet on a Tokamak and two weeks?
- 8:31David Kingham: And, and the well, the answer is yes you can.
- 8:35David Kingham: So long as you've got everything prepared beforehand.
- 8:38David Kingham: Yeah.
- 8:39David Kingham: So this is, um, I mean it was a very, um, uh, Heath Robinson sort of, uh, yeah.
- 8:46David Kingham: Experiment involving a cryostat made of plywood, some aluminum foil so that it didn't leak and you could pour liquid nitrogen in, uh, and then a coil was wound out of 25 meters of this superconductor.
- 9:06David Kingham: We worked out how to connect.
- 9:08David Kingham: A power supply to the superconductor and it all sort of boiled and fizzed, but it worked.
- 9:16David Kingham: It worked.
- 9:17David Kingham: Yeah.
- 9:17David Kingham: We produced a, a significant mag magnetic field with very rudimentary set up and engineering and the talk mat worked.
- 9:28David Kingham: So, um, so then we went to, um, investors who were interested and said, actually this new material does the job we hoped, um, and we can see how to make more powerful magnets using this material.
- 9:48David Kingham: And it gives us a route to commercial fusion energy.
- 9:53David Kingham: Um, yes.
- 9:53David Kingham: And then we worked out all the other things we'd need to do on, on, on that journey.
- 10:01Chris Reichhelm: So, so that actually, you know, so getting to that, that milestone, if you will.
- 10:07Chris Reichhelm: So experimenting with this new material, the Heath Robinson approach you took to kind of validate that initial approach and the material.
- 10:16Chris Reichhelm: Yeah.
- 10:16Chris Reichhelm: How many people did you have in the company at that point?
- 10:20David Kingham: Um, three.
- 10:24David Kingham: Okay.
- 10:24David Kingham: Three.
- 10:25David Kingham: Yeah.
- 10:25David Kingham: Three of us at that point?
- 10:26David Kingham: Yes.
- 10:27Chris Reichhelm: And I mean, we had capital.
- 10:30David Kingham: Yeah.
- 10:31David Kingham: How much capital.
- 10:31David Kingham: But you had help from others too.
- 10:34David Kingham: Yeah.
- 10:34Chris Reichhelm: And how much
- 10:34David Kingham: capital had you raised as well?
- 10:37David Kingham: About $200 million.
- 10:39David Kingham: Two?
- 10:39David Kingham: No, about $200,000.
- 10:42David Kingham: Two.
- 10:42David Kingham: Okay.
- 10:45Chris Reichhelm: Hundred thousand dollars.
- 10:46Chris Reichhelm: Alright.
- 10:47Chris Reichhelm: So $200,000 raised at that point.
- 10:50Chris Reichhelm: Three people.
- 10:52Chris Reichhelm: And you had already come to a conclusion, hey, if we can now just continue to focus on this and build this and scale this up, we can get to a point that doesn't, that seems like actually a reasonable return given the amount of money invested.
- 11:05Chris Reichhelm: Sure.
- 11:06Chris Reichhelm: And, uh, and the talent that you had on board.
- 11:09David Kingham: Yeah, and we were, we were certainly first to really see that, um, high temperature superconductors could be used successfully to make magnets for magnetic confinement fusion when, when the material had first been discovered in 1987, lots of people were speculating that it could be useful for fusion.
- 11:32David Kingham: But then everything went quiet because manufacturing the superconductor was so difficult.
- 11:39David Kingham: It was only 2011 really, that the manufacturers had worked how to make the material, uh, that we're now able to use.
- 11:51Chris Reichhelm: And did Oxford Instruments continue to act as a partner or supplier to Tokamak energy, or did you have to go off and do this yourself?
- 12:00David Kingham: Um, yeah.
- 12:01David Kingham: So Oxford Instruments then worked with us for another four years mm-hmm.
- 12:06David Kingham: To scale up the technology.
- 12:09David Kingham: We were both learning about the material and the technology as, as we went forward, but we needed their superconducting magnet expertise.
- 12:20David Kingham: And we got to 2015 when we were able to demonstrate a plasma for over 24 hours in a small Tokamak constructed with high temperature superconducting magnets.
- 12:34David Kingham: Um, and that was a big milestone for the company.
- 12:38David Kingham: And that Yes, meant we could raise, um, about $15 million, um, okay.
- 12:44David Kingham: To really push things forward.
- 12:47Chris Reichhelm: And so, David, in terms of technology readiness level, at this point, by 2015 you get to that next milestone, where would you say you were at that point?
- 12:56David Kingham: Um.
- 12:58David Kingham: Yeah, it's technology, redness level two or three.
- 13:02David Kingham: I mean, it's, it's
- 13:03Chris Reichhelm: okay.
- 13:04Chris Reichhelm: A functional, functional time approach.
- 13:05Chris Reichhelm: Time.
- 13:06Chris Reichhelm: So this is still a function of research.
- 13:07Chris Reichhelm: This is a functional pro.
- 13:08Chris Reichhelm: Okay.
- 13:09Chris Reichhelm: Oh, that's interesting.
- 13:10Chris Reichhelm: Yep.
- 13:10Chris Reichhelm: Yeah.
- 13:10Chris Reichhelm: Alright.
- 13:11Chris Reichhelm: So you've, okay, so you're still very early stage there, but you've got enough to contain plasma, is that right?
- 13:19Chris Reichhelm: Am I understanding that correctly?
- 13:21Chris Reichhelm: To contain plasma for a period of 24 hours using materials and systems that would broadly be in place within a fully scaled Tokamak
- 13:31David Kingham: Yeah, yeah.
- 13:33David Kingham: No modest experiment by today's standards.
- 13:36David Kingham: Sure.
- 13:36David Kingham: But, but it, it, yeah.
- 13:38David Kingham: Did the job.
- 13:39David Kingham: Um, at that point we decided this, this superconducting material, this fantastic material, um, we need to build our own team.
- 13:52David Kingham: We can't be reliant on someone else to do the development because we want to go at, at our pace.
- 13:58David Kingham: Yes.
- 13:58David Kingham: Um, so we, but by then we had enough credibility, enough people knew about us that we could recruit a really good team and, and then you, you get this effect that, um, we're trying to build a business based on fusion and superconducting magnets and we're in a place Oxford, where there's 50 years history of research in tokamaks and 60 or 70 years history of research in superconducting magnets.
- 14:35David Kingham: Mm-hmm.
- 14:35David Kingham: So you've got all this human capital in the area.
- 14:37David Kingham: Yeah.
- 14:38David Kingham: That makes it feasible to do really difficult things.
- 14:43Chris Reichhelm: Yes.
- 14:44Chris Reichhelm: Some segments of the deep tech universe are associated with science projects.
- 14:50Chris Reichhelm: More than businesses.
- 14:51Chris Reichhelm: Yeah.
- 14:52Chris Reichhelm: And for many nuclear fusion has been one of those, the big Sure.
- 14:55Chris Reichhelm: You know, the big adage with nuclear fusion was it's always 30 years away.
- 14:59Chris Reichhelm: Yeah.
- 15:00Chris Reichhelm: And in until now, one gets the sense.
- 15:03Chris Reichhelm: Now hopefully it's not another 30 years.
- 15:05Chris Reichhelm: One gets the sense we're closing in on it.
- 15:08Chris Reichhelm: At what point was 2015 the point for you guys where it stuck, it shifted from kind of science project to now business?
- 15:20David Kingham: Um, no, I think it was still, still a science project at that stage.
- 15:25David Kingham: Um, if we a, after 2015 we, we were still, um, judging success of the business and, and reporting to shareholders based on technical progress.
- 15:40David Kingham: Um, there were no sort of commercial milestones.
- 15:43David Kingham: We weren't promising to sell anything to anybody.
- 15:46David Kingham: Yes.
- 15:47David Kingham: Um, we set a series of milestones, which were.
- 15:51David Kingham: Achieving a three Tesla magnet, a five Tesla magnet.
- 15:56David Kingham: Okay.
- 15:56David Kingham: Going up to 10.
- 15:58David Kingham: I mean, Tesla is a, a measure of magnetic field, uh, strength.
- 16:04David Kingham: Um, conventional superconductors can typically get up a bit above 10.
- 16:09David Kingham: Tesla.
- 16:11David Kingham: High temperature superconductors have the promise of getting to 25 Tesla, 30 Tesla or more if you need it.
- 16:20David Kingham: And they can do that in a fusion device, um, which low temperature superconductors really, really can't do.
- 16:29David Kingham: So we had to have these goals for increasing field strength.
- 16:35David Kingham: Yes.
- 16:36David Kingham: And we also set, um, a really big goal infusion of getting to 100 million degree plasma temperature.
- 16:46David Kingham: Yes.
- 16:47David Kingham: Um, now.
- 16:49David Kingham: In retrospect, why is that important?
- 16:51David Kingham: So, a hundred million degrees is, is really the threshold for necessary for commercial fusion energy.
- 16:59David Kingham: If you have a temperature that high, you get, um, energetic collisions between ions and that significantly increases the probability of fusion reactions happening.
- 17:12David Kingham: So you, you have to get your plasma to that sort of a hundred million degree and above temperature, and it doesn't matter whether it's a to America, spherical to America accelerator or laser inertial fusion, you still have to get your plasma to hundred million degrees.
- 17:32David Kingham: So you get collisions are energetic enough.
- 17:35David Kingham: So the combine and produce.
- 17:40Chris Reichhelm: Okay, so that's interesting.
- 17:42Chris Reichhelm: Regardless of the design, then that 100 million degrees is absolutely critical so that you create Yep.
- 17:48Chris Reichhelm: What sounds like the conditions for fusion then to start taking place.
- 17:53David Kingham: Yep.
- 17:53David Kingham: So we set that goal.
- 17:55David Kingham: Our next device we will reach a hundred million degrees and, um, very few fusion devices have actually reached that temperature.
- 18:10David Kingham: Um, the JET tokamak in the uk, TFTR in, in the states, a Japanese tokamak and more recently the National Ignition Facility in the States have gotta the, that sort of temperature.
- 18:26David Kingham: But yes, nothing, nothing else has,'cause it's really, really difficult.
- 18:33Chris Reichhelm: Yes.
- 18:35David Kingham: So.
- 18:37Chris Reichhelm: Now, if I may, let me ask a question.
- 18:39Chris Reichhelm: Early investors who are coming in to support the development of Tokamak Energy, and we've talked about how, uh, it, it, it's still, and it sounds like it had to continue being a science project in order for you to at least be able to demonstrate that the vehicle you were creating was capable of creating the conditions For sure.
- 19:04Chris Reichhelm: The type of energy you're trying to generate.
- 19:06Chris Reichhelm: And so, uh, but were they, how does that work from, you know, your perspective as a company trying to generate investment to keep yourselves going, knowing that there's no immediate prospect of commercial activity?
- 19:25David Kingham: Yeah, the a hundred million degree target was really agreed with the, with the shareholders, with the investors, um, as being.
- 19:37David Kingham: Necessary, but perhaps not sufficient to take us all the way to Yes.
- 19:43David Kingham: Uh, fusion energy.
- 19:44David Kingham: Commercial fusion energy.
- 19:46David Kingham: Yes.
- 19:47David Kingham: And, um, so they were very happy with, you know, that bold goal.
- 19:56David Kingham: Uh, and then what has happened in, in practice is, um, that the, the business has moved from trying to do everything itself into much more of a partnership collaboration model with government and with other private companies.
- 20:20David Kingham: Yes.
- 20:20David Kingham: So our market position now is, um, we know how to build tokamaks.
- 20:29David Kingham: We know how to build high temperature superconducting magnets.
- 20:33David Kingham: We know about plasma control systems and so forth.
- 20:37David Kingham: Those, those all work fine.
- 20:40David Kingham: Um, so we are nicely positioned to be a partner in major government funded projects.
- 20:49David Kingham: For example, in the uk in Japan, milestone driven program in the States.
- 20:56David Kingham: Yes.
- 20:56David Kingham: So we're looking for, um, alliances, collaborations to take the technology forward.
- 21:05David Kingham: Yes.
- 21:06David Kingham: We're looking in some cases for governments to be the customer.
- 21:09David Kingham: Um, yes.
- 21:11David Kingham: At development, uh, in other cases to be the co-funder.
- 21:16David Kingham: Um, so we're using shareholders funds very efficiently.
- 21:22Chris Reichhelm: Mm-hmm.
- 21:23Chris Reichhelm: Um, but at the early stage then, so up until this point, I guess it's a matter of.
- 21:30Chris Reichhelm: Targeting the right kind of investors who see the world in a slightly different way, who I'm guessing, for lack of a better term, are just the most extraordinarily long sighted investors who believe in the, in the, in the potential impact of what you, of what can be created directly and indirectly.
- 21:54Chris Reichhelm: Sure.
- 21:55Chris Reichhelm: Is that a fair assessment?
- 21:57David Kingham: Yeah, I think that's e exactly right.
- 21:59David Kingham: That our early investors, um, liked the scientific argument, the spherical Tokamak being very efficient, and they love the properties, the fundamental properties of the high temperature superconductor.
- 22:15David Kingham: Uh, I mean, it's a material that delivers, uh, huge current densities, uh, even in a strong magnetic field.
- 22:25David Kingham: Even at relatively high temperatures, like 20 degrees above absolute zero.
- 22:31David Kingham: Um, so our investors could easily see the potential, even if, you know, the business model might need to change over time.
- 22:45David Kingham: Uh, yes.
- 22:46David Kingham: To get the whole, get the whole job done.
- 22:48David Kingham: Yes.
- 22:49David Kingham: Um, yeah.
- 22:51David Kingham: So, and of course you
- 22:52Chris Reichhelm: were the CEO from the early days.
- 22:56Chris Reichhelm: Yeah.
- 22:56Chris Reichhelm: And you mentioned 2015 you hurt your, you, you achieved, uh, another significant milestone and that thereafter you, it was still a science project, but with the raising of an additional 15 million pounds, uh, you could move forward in a, in a, in a way with clear targets, even on some of those future technical milestones.
- 23:21Chris Reichhelm: At what point, David, did you feel that it was time to hand over the reins to a new CEO?
- 23:29David Kingham: Right.
- 23:29David Kingham: So, um, this was about 2017.
- 23:33David Kingham: Um, our a hundred million degree.
- 23:36David Kingham: Uh, target was still a bit out of reach.
- 23:39David Kingham: Um, but we had achieved an intermediate target of 15 million degree plasma temperature.
- 23:46David Kingham: Um, which is not insignificant achievement.
- 23:51David Kingham: It's hotter than the center of the sun.
- 23:54David Kingham: Um, but we realized there was some serious engineering to do to, um, really get through a a and some clever physics to be done to, yes, to get through to a hundred million degrees.
- 24:11David Kingham: Um, so we did several things there.
- 24:14David Kingham: Um, it was pretty clear we needed stronger engineering leadership.
- 24:19David Kingham: I'm really a theoretical physicist by training, so it's time for me to step, uh, into a support more of a supporting role.
- 24:28David Kingham: Um, get an engineering chief executive in.
- 24:33David Kingham: Um, then, uh, we also established a collaboration with Princeton and Oak Ridge National Labs in the states funded by US Department of Energy, um, so that they could help us with some of the plasma physics, um, that would help us get to this a hundred million degrees.
- 24:58David Kingham: Um, and, uh, we got there in, well, we announced it in 2022.
- 25:05David Kingham: Um, looking back on the data, we, we were there or thereabout in 2021.
- 25:10David Kingham: Um, so, but we wanted to, with that 100
- 25:14Chris Reichhelm: million degree target
- 25:16David Kingham: with a hundred million degree.
- 25:19David Kingham: Target achieved and achieved.
- 25:24David Kingham: Um, now it would be easy to claim and easy to not measure things perfectly.
- 25:31David Kingham: Mm-hmm.
- 25:32David Kingham: Um, so we really wanted to be absolutely sure that the measurements were robust, repeatable, peer reviewable backed up by colleagues at, um, Princeton and Oak Ridge who know about measuring these plasma temperatures.
- 25:52David Kingham: Yes.
- 25:53David Kingham: Um, so we, we certainly wanted to go right at the No, a maximum scientific proof point, uh, end of things.
- 26:04David Kingham: Yes.
- 26:05Chris Reichhelm: Yes.
- 26:06Chris Reichhelm: Gearing up even, I mean, getting to 15 million degrees is, uh, is one thing.
- 26:12Chris Reichhelm: Getting to a hundred is another thing.
- 26:14Chris Reichhelm: These are incredible engineering challenges.
- 26:18Chris Reichhelm: Um, how, can you talk a little bit about how you guys approach that from a, you know, a, a capability standpoint?
- 26:27Chris Reichhelm: Where did you know, where did the talent come from?
- 26:30Chris Reichhelm: How are things organized?
- 26:32Chris Reichhelm: There are lots of our listeners who are, who, who, who are also wrestling, who with, with, with huge engineering challenges and thinking about the, that which is required to galvanize motivate and at the end of the day, get the results that are required in order for you to hit the milestone.
- 26:57Chris Reichhelm: What kind of lessons did you learn from that whole experience?
- 27:02Chris Reichhelm: Um, well one,
- 27:04David Kingham: the way we worked was sort of was incremental.
- 27:09David Kingham: Um, you know, we weren't.
- 27:13David Kingham: We had incremental milestones.
- 27:15David Kingham: Uh, I mean we had the 15 million degree and a hundred million degree milestone and, and the increasing magnetic field strength milestones in, um, with the superconducting magnets.
- 27:28David Kingham: Um, but the, the team evolved, um, and, and the sense of it was very different from a sort of big scale government led program, which tends to start with, um, specification requirement, and then recruiting a large team to deliver.
- 27:55David Kingham: So a rapid scale up of people and then progress towards the project.
- 28:01David Kingham: We were, we were much more, um, we'll only recruit more people if we achieve the previous milestone.
- 28:08David Kingham: And so learn as you go on, on the scale up.
- 28:13David Kingham: Now that may not be the fastest way of getting there.
- 28:17David Kingham: Um, and it, but, but it has the advantage that if something doesn't work out quite as expected, you're not over committ to pursuing it.
- 28:33David Kingham: So you, in a lot of, um, publicly funded programs, you have the big risk of, um, sunk cost argument.
- 28:42David Kingham: You know, we spent 30 million pounds on this, we have to proceed.
- 28:46David Kingham: Yes, yes.
- 28:47David Kingham: Now, we never got into any, any of that sort of thinking.
- 28:52David Kingham: Uh, some of our very early shareholders said, never take a decision to push on if the evidence doesn't support it.
- 29:03David Kingham: Um, yes.
- 29:04David Kingham: And so we cut.
- 29:06David Kingham: You know, we cut a few things, learn fast, forced ourselves to do things with relatively modest resources.
- 29:18David Kingham: Uh, and then, and, and, and the other thing we were trying to do with the magnets in particular was to achieve the highest possible field strength in the smallest possible magnet.
- 29:32David Kingham: So you're using materials as efficiently as possible.
- 29:37David Kingham: Okay.
- 29:37David Kingham: And you're really, you're not physically physical size.
- 29:42David Kingham: Scale up can come later.
- 29:43David Kingham: Once you're satisfied, you can handle the engineering once you get through
- 29:48Chris Reichhelm: the prototypes, successful prototypes for the thing that you are.
- 29:51Chris Reichhelm: So, so if I'm hearing correctly, one of the things that may be, and it's interesting, the, the piece around resource constraint around not growing too quickly.
- 30:06Chris Reichhelm: But making sure that, for want of a better phrase, you've ma you've mastered the lesson that the challenge is trying to teach, if you will, and that you can represent that in a, uh, you know, at the TRL four five stage where you're developing your prototypes.
- 30:26Chris Reichhelm: Uh, don't worry about the size of the prototype.
- 30:29Chris Reichhelm: Uh, at that stage can you actually try to do what you're trying to do.
- 30:34Chris Reichhelm: So if I'm hearing correctly, almost stay small.
- 30:37Chris Reichhelm: Don't worry about trying to scale so fast.
- 30:40Chris Reichhelm: Stay small until you've got it, and then you can worry about the challenges associated with scaling later on.
- 30:47Chris Reichhelm: Yeah.
- 30:47Chris Reichhelm: Would that be a fair summary?
- 30:48David Kingham: Yeah.
- 30:49Chris Reichhelm: Summary.
- 30:49Chris Reichhelm: I think that's, that's a fair summary.
- 30:51Chris Reichhelm: Yeah.
- 30:51Chris Reichhelm: Of course.
- 30:52Chris Reichhelm: While you're doing this, you are trying to file patents on Yeah.
- 30:58Chris Reichhelm: Uh, all sorts of innovations you come up with.
- 31:01Chris Reichhelm: Some of which are driven by trying to do things in as compact, a small, uh, manner as possible.
- 31:08Chris Reichhelm: Yes.
- 31:08Chris Reichhelm: Um, you are also building your supply chain relationships.
- 31:12Chris Reichhelm: Absolutely.
- 31:12David Kingham: Um, learning that in the high temperature superconducting world, there are many manufacturers of the basic material and then very few people who know how to turn that material into powerful magnets, uh, robust, powerful magnets.
- 31:30David Kingham: Um, so we had, we used quite a few different suppliers, um, and learn how some of the different, some manufacturers produce better types than others, um, or different properties, um, you know, different manufacturing techniques.
- 31:52David Kingham: We use different costs from various manufacturers.
- 31:57David Kingham: And here we are making lots of little magnets and learning quickly how to use everybody's material.
- 32:03David Kingham: We're also developing, um, sophisticated modeling software.
- 32:11David Kingham: So, you know, you build a small prototype, you measure everything you can, uh, and then you build your numerical models, your software and simulation, so you really understand how these small magnets work.
- 32:29David Kingham: And then you can, with confidence design a bigger magnet and a more powerful magnet.
- 32:36David Kingham: And then you test that.
- 32:37David Kingham: And if, if that works as intended, you'll get more confident in your, in your modeling and simulation.
- 32:45Chris Reichhelm: So that, how, how, how reliable are the models?
- 32:49Chris Reichhelm: Or if you are continuing to experiment at.
- 32:54Chris Reichhelm: These smaller scales, how much is scale a factor in the realization of what you're ultimately trying to achieve?
- 33:03Chris Reichhelm: You know, how much more do you have to account for scale when it's finally time to, you know, is it's, it's always more than just a matter of, well, we'll just here are scale up ratios and there you go.
- 33:15David Kingham: Yeah, sure.
- 33:16David Kingham: Because manufacturing techniques have to change as you scale up.
- 33:20David Kingham: Sure.
- 33:21David Kingham: Yeah.
- 33:21David Kingham: Um, so we started off winding superconducting magnets as a, as a spiral of tape, um, uh, and circular section.
- 33:34David Kingham: Uh, and that's relatively easy to do, uh, and we've got more and more efficient at that.
- 33:41David Kingham: Um, then you need to think of larger scale and then different shapes, because some of the coils in the Tokamak have to be more or less a D shape rather than a circular, uh, shape.
- 33:59David Kingham: And that creates additional manufacturing challenges.
- 34:04David Kingham: Um, so you are trying to work out the manufacturing challenges at the same time as developing the software and simulation.
- 34:12David Kingham: So you can predict how the magnet should work.
- 34:15David Kingham: You build one test it, did it work as intended?
- 34:19David Kingham: If not, well, you know what, what's happened is our modeling software not quite right.
- 34:25David Kingham: Is the manufacturing technique not quite right?
- 34:28David Kingham: Yeah.
- 34:28David Kingham: Did the manufacturer supply us?
- 34:31David Kingham: You know, did we misunderstand the spec of the tape?
- 34:34David Kingham: All of these challenges need to be dealt with.
- 34:38Chris Reichhelm: And are these things you're actually just learning on the job learning as you are understanding how to build these?
- 34:45David Kingham: Uh, yeah, there's a lot of that.
- 34:47David Kingham: Yeah.
- 34:48David Kingham: Uh, and you're trying to build your knowledge base so that Yeah.
- 34:53David Kingham: You've got a substantial knowledge base as possible, and then you are doing rapid incremental innovation on top of that to,
- 35:02Chris Reichhelm: uh, scale
- 35:03David Kingham: up.
- 35:03David Kingham: And how does
- 35:03Chris Reichhelm: this approach this, you know, this, you know, because you're building something that hasn't been built before.
- 35:10Chris Reichhelm: You're building something that's new.
- 35:12Chris Reichhelm: You're trying to create something that's never existed.
- 35:14Chris Reichhelm: How did this impact your hiring decisions?
- 35:20David Kingham: Um, yeah, the,
- 35:23Chris Reichhelm: I mean, there are, because it's not like you can say, well, we're looking for people with experience of building spherical tokamak of innovation.
- 35:31Chris Reichhelm: No, exactly.
- 35:32Chris Reichhelm: Exactly.
- 35:34Chris Reichhelm: So, so did it impact your hiring and if so, how?
- 35:38David Kingham: Well it did, because in the Oxford area, you have some mature superconducting magnet businesses.
- 35:46David Kingham: Um, Oxford Instruments themselves have made high performance.
- 35:51David Kingham: Scientific instruments from, um, low temperature superconductors for many decade, decades.
- 35:59David Kingham: Um, Siemens, um, magnet technology, magnetic resonance imaging business, they make, uh, 40% of the world's MRI magnets, uh, in oxygen.
- 36:14David Kingham: Now, the people working in those programs are working on not quite repeating routine, but it, it is manufacturing discipline, uh, not too much innovation, very structured, uh, approaches.
- 36:35David Kingham: And, and in MRI, obviously regulatory, regulatory controlled, um, challenges.
- 36:44David Kingham: Um, so some engineers like that, the ones who don't.
- 36:50David Kingham: Are the sort of ones who joined our team to try new materials, to be in a more of a skunk work sort of approach to seeing how far you can go with this new material.
- 37:04David Kingham: Yes,
- 37:05Chris Reichhelm: yes.
- 37:06Chris Reichhelm: And is there any advice you have for filtering out those skunk works lovers, those, you know, those highly entrepreneurial Heath Robinson types?
- 37:19David Kingham: Yeah.
- 37:20David Kingham: Um, well this, they, they tend to, they, they tend to cluster in particular parts of the world.
- 37:29David Kingham: No, they, they need Now Oxfordshire is also great for motor sport engineering Formula One teams, and that again is there's a certain culture of people who love, the, the petrol head love tinkering with the cars and trying to get them to go faster whilst remaining reliable.
- 37:53David Kingham: And we've got something of the similar ethos in the superconducting magnet area that, um, you need to design things.
- 38:03David Kingham: They have to be bold, they have to work,
- 38:07Chris Reichhelm: they have to be precise.
- 38:09Chris Reichhelm: Yeah.
- 38:09Chris Reichhelm: You know, that love of precision and performance and safety has to be in there too, but Yeah.
- 38:16David Kingham: Yeah.
- 38:17David Kingham: And then no, we, we, we then have challenges of scaling up of magnets.
- 38:23David Kingham: So the, the way in which you safely control a small magnet, um, so that it can't burn out if there's a loss of superconductivity, a quench, um, is it turns out to be very different or requiring very different approaches and materials.
- 38:41David Kingham: To go to a large magnet where the stored energy in the system is much greater and the risk of breaking your whole magnet system with a loss of superconductivity is, is yes.
- 38:55David Kingham: Now is a big challenge.
- 38:58David Kingham: Yes.
- 38:58David Kingham: So you, you have to be able to cope with that scale up.
- 39:01David Kingham: Um, yes.
- 39:03David Kingham: Challenge.
- 39:03David Kingham: Yes.
- 39:04Chris Reichhelm: And, and David, bring us up to today.
- 39:07Chris Reichhelm: So the, you know, the journey you've been on, you've just wonderfully articulated and summarized for us.
- 39:13Chris Reichhelm: Where is Tokamak energy today?
- 39:15Chris Reichhelm: What does it want to be when it grows up?
- 39:19David Kingham: Um, we, we really, on, on the fusion side, we want to be at the heart of major projects aimed delivering fusion energy.
- 39:30David Kingham: Um, and we expect these projects to be backed by governments around the world.
- 39:38David Kingham: Um.
- 39:39David Kingham: It's a great project called Step in the uk, where we're in prime position to be the engineering partner or part part of the engineering partnership team to deliver that.
- 39:51David Kingham: Um, we're engaged in the US milestone driven fusion development program.
- 39:57David Kingham: Um, and we're in dialogue for a project in Japan, which would deliver, um, well potentially fusion electricity, uh, in the 2030s, mid 2030s.
- 40:12David Kingham: If, uh, if things go well, we're expecting Japanese government announcements on that fairly soon.
- 40:19David Kingham: Um, so yeah.
- 40:23David Kingham: Um, and we know that in Europe there's also growing enthusiasm for fusion.
- 40:31David Kingham: Some very positive announcements in Germany.
- 40:34David Kingham: Yes.
- 40:34David Kingham: Um.
- 40:35David Kingham: You know, new government, uh, going very profusion, uh, which is interesting for Germany, given the challenges, given it history.
- 40:44David Kingham: Yeah.
- 40:44David Kingham: They've had, um, the vision mission, um, yeah.
- 40:49David Kingham: Uh, and, and then the European Commission also, um, not wanting to be outdone by one, one of its member nations is, is looking at public-private partnership approach infusion.
- 41:01David Kingham: Mm-hmm.
- 41:02David Kingham: So, so it's
- 41:03Chris Reichhelm: about establishing itself kind of at the core of the entire value chain.
- 41:07Chris Reichhelm: Yep.
- 41:07Chris Reichhelm: And is this, with the view of supplying services, engineering services, at some stage, does Tokamak Energy become a product company?
- 41:19Chris Reichhelm: Is it going to become a, you know, a hey, we now supply Spherical Tokamak?
- 41:24Chris Reichhelm: Or do we partner up with a, I dunno, with Siemens and ABB and, and however many years, and they'll supply the Tokamak, but we provide the expertise and the support.
- 41:34Chris Reichhelm: Yeah.
- 41:35Chris Reichhelm: You know, what exactly will it do or will it do all of those things potentially?
- 41:39David Kingham: Um, well, we shall see, but, um, we were very fortunate, um, a couple of years ago to get to Warren East to join our board.
- 41:50David Kingham: Now, Warren was previously, um, chief executive of Rolls Royce, but prior to that he was Chief Executive of Arm Holdings, which has successfully embedded its intellectual property in most of the world's advanced microprocessors.
- 42:09David Kingham: Mm-hmm.
- 42:10David Kingham: Now that when he joined, he said he wants to see Tokamak Energy become the arm of Fusion to own crucial intellectual property in all future Fusion devices around the world.
- 42:26David Kingham: So if we can achieve that sort of high valuation, relatively low capital requirement to do the development.
- 42:37David Kingham: Of course, we're partnering but embedding our technology.
- 42:41David Kingham: Um, software know-how systems may be high value components as well within, uh, many devices.
- 42:52David Kingham: Um, you know, fusion can take a few more years to develop.
- 42:57David Kingham: Um, what won't change is humankind will continue to pursue fusion because it is so exciting and so important and will inevitably be the dominant source of energy in the 22nd century.
- 43:14David Kingham: Just be good to get it sooner than that.
- 43:18Chris Reichhelm: Do you think the world will allow it?
- 43:21Chris Reichhelm: Do you think?
- 43:22Chris Reichhelm: Yes.
- 43:22Chris Reichhelm: You know, you know, you know, given how fossil fuels are so embedded in and power the geopolitical landscape, energy powers the geopolitical landscape to a certain extent.
- 43:32Chris Reichhelm: And, uh, you know, yeah.
- 43:34Chris Reichhelm: Perhaps in the 22nd century, maybe, maybe, maybe when we've, uh, but, um, but one, I guess one of the questions I, or the things I worry about, if we were to create fusion, would the world allow us to use it?
- 43:48David Kingham: Oh, I, I, I think so, because it's inherently safe.
- 43:53David Kingham: Um, there's plentiful fuel.
- 43:55David Kingham: Um, it doesn't require huge amounts of land.
- 43:59David Kingham: Um, there are proliferation risks very, very low compared to fish and Sure.
- 44:07David Kingham: Um, so, but, but I think what will drive fusion development is it's a bit of geopolitics.
- 44:15David Kingham: The, um, particularly between the US and China.
- 44:20David Kingham: Yes.
- 44:20David Kingham: Um, the US will not wanna be left behind and the new energy secretary has, you know, made that clear that the US wants to be dominant in energy and in energy innovation.
- 44:36David Kingham: Yes.
- 44:36David Kingham: So we take that to be very positive.
- 44:39David Kingham: And of course Europe won't want to get left out either.
- 44:42David Kingham: We're seeing that reaction quite, quite strongly now.
- 44:47David Kingham: Yes.
- 44:48Chris Reichhelm: But as China continues to dominate the market for many energy technology products, right now, they have the leverage and Yeah with their form of government, which can get behind new platform technologies with all the might and capital required, and increasingly talents too.
- 45:10Chris Reichhelm: Um, they're the, uh, you know, they may be the game to beat.
- 45:14David Kingham: Yeah.
- 45:16David Kingham: We, we watch with great interest, what's what's going on in China?
- 45:20David Kingham: And it is not insignificant.
- 45:23David Kingham: And we have direct competition, um, in spherical tomax in China, perhaps strongest competition to our technology.
- 45:34David Kingham: Interesting.
- 45:36Chris Reichhelm: Interesting.
- 45:37Chris Reichhelm: The, the, um, so Tokamak Energy is now at this kind of juncture.
- 45:42Chris Reichhelm: It's moved, you know, it's, it's along with continuing its development of the spherical Tokamak.
- 45:48Chris Reichhelm: Uh, it continues to learn about and, and produce and design new tech and patent new technologies and systems and materials and work with partners to do all of this so that it can position itself at kind of the center of this emerging industry.
- 46:04Chris Reichhelm: When, when you think about the, the next phase of growth for the company.
- 46:12Chris Reichhelm: The skills it's gonna need in order to fully occupy and the its position in the value chain and play on a much more global stage.
- 46:22Chris Reichhelm: What, you know, what skills and experience and talents will you need that you don't currently have right now.
- 46:30Chris Reichhelm: And do you think you'll be able to fulfill those from the uk?
- 46:37David Kingham: Uh, yeah.
- 46:38David Kingham: So there's, there's different elements to this.
- 46:41David Kingham: I mean, one is, is our business model.
- 46:45David Kingham: Um, for example with, with the superconducting magnet side of the business, the model now is to look for large engineering companies that can basically take our technology and take it to very large markets, um, because they have the market relationship.
- 47:08David Kingham: So very recently, we've had.
- 47:10David Kingham: A huge amount of interest from Japanese engineering companies.
- 47:16David Kingham: Um, we have, um, significant investment from Furukawa Electric who own superpower, so they're manufacturers of high temperature superconducting material.
- 47:30David Kingham: Um, they have assessed very carefully our engineering design capabilities and, um, decided, uh, to make a substantial investment in the company and then to introduce us to other large Japanese companies who are, um, able to get superconducting technology into some very large opportunities.
- 47:58David Kingham: Mm-hmm.
- 47:59David Kingham: Um, so that is one part of our strategy of leverage.
- 48:04David Kingham: Mm-hmm.
- 48:05David Kingham: So we will invest in the early stage innovation up to TRL six or seven.
- 48:13David Kingham: Um, we can recruit enthusiastic magnet engineers who love the challenge of getting to that point, and then we hand over to either a joint venture manufacturing opportunity or, or a pure licensing or some other tech transfer arrangement so that a product that depends on our technology is taken to market by someone else who has the go market skills and the customer relationships.
- 48:47David Kingham: Got it.
- 48:48David Kingham: Got it.
- 48:48David Kingham: So we see that model.
- 48:52David Kingham: Um, I mean we have more than half a dozen large, large live opportunities of that type.
- 49:02David Kingham: Into quite different sectors, um, you know, propulsion systems for land, sea, air space, um, where interesting compact, relatively lightweight superconducting magnets can make a big difference.
- 49:24David Kingham: Yes.
- 49:24David Kingham: Um, difference.
- 49:25David Kingham: One of those projects is, um, a, a DARPA project on submarine propulsion.
- 49:33David Kingham: Um, it, yeah, it's in, in the public domain.
- 49:37David Kingham: Um, yes, our magnets can deliver the magnetic field strength that is required for efficient magneto hydrodynamic drive, but the technology's gonna be pretty complex to develop, so I don't think it's gonna happen anytime very soon.
- 49:56David Kingham: Yes.
- 49:58David Kingham: But
- 49:58Chris Reichhelm: in, in these situations though, then you are identifying additional applications.
- 50:04Chris Reichhelm: Yes.
- 50:05Chris Reichhelm: Or IT or additional application areas are being identified by someone.
- 50:10Chris Reichhelm: Yes, yes.
- 50:11Chris Reichhelm: Either from within to come back energy or from someone outside who then looks at what you are developing and says, oh, that's interesting.
- 50:18Chris Reichhelm: Yes.
- 50:18Chris Reichhelm: And so you have this, it's not quite the arm model because arm focused on the design or here's a blueprint, and then the designers could then go and design the chips using the ARM blueprint, and then CSMC would make 'em.
- 50:32Chris Reichhelm: And, uh, but you've got, you know, so you're designing some of it to a point and you've got a whole library of patents and so on.
- 50:40Chris Reichhelm: And then in some areas, I'm guessing over time you may go on to develop more of the technology.
- 50:46Chris Reichhelm: Or, you know, advance it to a particular stage.
- 50:48Chris Reichhelm: In other cases you may not need to do it as much, but you are then reliant on this, on these relationships with these big global partners who can help you scale and get to market.
- 50:57David Kingham: Yes.
- 50:58David Kingham: And then of course you have commercial negotiations.
- 51:00David Kingham: Is it?
- 51:02David Kingham: Yes.
- 51:02David Kingham: Non-exclusive license.
- 51:03David Kingham: Is it an exclusive license?
- 51:05David Kingham: What are the performance Yes.
- 51:07David Kingham: Criteria?
- 51:09David Kingham: Um, yes.
- 51:10David Kingham: Uh, is it split geographically and Yeah.
- 51:14David Kingham: Yes.
- 51:15David Kingham: Um, so you know, David, if I were to ask you
- 51:18Chris Reichhelm: Yes.
- 51:19Chris Reichhelm: Yeah, no, so those commercial skills, um, and strategic business development skills are, uh, are, are, are critical there.
- 51:27Chris Reichhelm: Let me take you out of Tokamak Energy for a second.
- 51:29Chris Reichhelm: You've been in the industry for a long time.
- 51:31Chris Reichhelm: Certainly been very active in the science community for, for a very long time.
- 51:36Chris Reichhelm: If you were to look at the uk, and we talk a lot on this program, and it's talked a lot generally about the failure of our country to get of the uk to get more, uh, companies through the lab to market journey through true TL nine and in the market, and if they're manufacturing stuff, MRL 10 and actually becoming proper, you know, proper businesses.
- 52:00Chris Reichhelm: If you think about that more broadly across the uk, is the model that you are developing is that, you know, you know, could that become a blueprint for other companies, do you think, and do you think there are other things we could be doing as, you know, within the UK to get more of these, more of these enterprises to market?
- 52:24David Kingham: I, I certainly think there's more that could be done in the UK to get the sort of IP intensive early stage in innovation companies to market.
- 52:35David Kingham: I think.
- 52:37David Kingham: The UK is naturally good at the early stage innovation and tends to not be so good when it comes to large scale manufacturing.
- 52:51David Kingham: Um, and yeah, I trying to be good at large scale manufacturing, for example, of batteries, you know, doesn't seem, I don't think we're likely to succeed in that.
- 53:07David Kingham: Hmm.
- 53:08David Kingham: Yeah.
- 53:08David Kingham: There, you know, there are too many other countries who are better placed.
- 53:12David Kingham: Um, but if it's more of a niche, um, like superconducting magnets, you know, the UK is a world leader in high field superconducting magnets, um, you know, with, with ourselves now and Oxford Instrument, Siemens and Yeah.
- 53:30David Kingham: And others.
- 53:31David Kingham: Um, it that.
- 53:36David Kingham: Feels like a, a much more likely to succeed strategy than chasing something, than reshoring
- 53:45Chris Reichhelm: and chasing a whole bunch of manufacturing.
- 53:48Chris Reichhelm: Yeah.
- 53:49Chris Reichhelm: I
- 53:49David Kingham: mean, some of that of course, but of course.
- 53:51David Kingham: Yeah.
- 53:52Chris Reichhelm: Yeah.
- 53:52David Kingham: But, but the, the arm model that, the high intellectual property model, the radical innovation, um, and then partnering, I think it's a nice way to go
- 54:07Chris Reichhelm: and perhaps the skill, because let's not forget the, the lessons learned from manufacturing and scaling are significant.
- 54:18Chris Reichhelm: Uh, they've enabled, I think, China to start developing their own ip.
- 54:24Chris Reichhelm: And to, you know, and to, and, and to, uh, um, and, and they enabled Japan and Korea and Taiwan and so on to become real innovators.
- 54:32Chris Reichhelm: So beyond just the manufacturing piece, it, you know, all of that expertise they gained ultimately allowed them to become innovators too.
- 54:40Chris Reichhelm: Yes.
- 54:40Chris Reichhelm: And so it's a, uh, but maybe to the point, um, by having those close partnerships with groups that can, are, are, you know, are, are capable of delivering things at scale and then taking the lessons, making sure that the executives or the talent in our businesses is taking the lessons from their interactions and bringing some of that home so that we're able to capture that ourselves to, you know, very often we see interesting platform technologies which may look good at, at the bench, uh, or in theory, but aren't ultimately scalable for one reason or another.
- 55:19Chris Reichhelm: And there's almost a sense that well, had we.
- 55:22Chris Reichhelm: Had we been more of a mindset to think about the scaling challenges upfront, we may not have gone down this line.
- 55:30Chris Reichhelm: And so, uh, and so a balance still has to be struck there.
- 55:35Chris Reichhelm: Yes.
- 55:36Chris Reichhelm: It sounds like Yeah.
- 55:37Chris Reichhelm: Or closer relationships with manufacturers, uh, and OEMs
- 55:41David Kingham: and, yeah.
- 55:44David Kingham: I mean, one of the things that has surprised us over the last couple of years is the number of new applications of the high temperature superconductors that we've become aware of.
- 55:55David Kingham: Um, and that often through dialogue with supply chain and then sort of coming across, um, p people.
- 56:10David Kingham: Yeah.
- 56:10David Kingham: Finding out that you have a potential solution to somebody's problem.
- 56:15David Kingham: Yeah.
- 56:15David Kingham: Um, so the mo most recent of those is.
- 56:20David Kingham: The possibility of using superconductors in data centers.
- 56:27David Kingham: So data centers are increasingly power hungry.
- 56:32David Kingham: The power density of the data centers is gonna increase dramatically with the latest NVIDIA chips.
- 56:39David Kingham: Um, so you know, they're gonna go up towards one megawatt, um, per rack, um, from a hundred hundred and 30 kilowatts or whatever it is at the moment.
- 56:53David Kingham: Oh wow.
- 56:53David Kingham: So this is, um, astonishing power requirements.
- 56:58David Kingham: And to get the power to the, to the chip, you need buzz bars.
- 57:04David Kingham: At the moment they use copper and aluminum and these buzz bars are getting big.
- 57:12David Kingham: Um, so they're occupying a significant amount of space within the data center, and they're generating huge amounts of heat.
- 57:19David Kingham: Hmm.
- 57:20David Kingham: Um, so on the other hand, they're conventional and routine easy technologies, but the point is gonna come where it's worth having a high temperature superconducting buzz bar in these data centers because it will deliver five times the amount of power in the same footprint as copper.
- 57:43David Kingham: Um, and yeah, even more so.
- 57:46David Kingham: That's fascinating.
- 57:47Chris Reichhelm: Are you, are you guys scouting out these applications or are, are, you know, is the demand side approaching you or is it a mix of both?
- 57:59David Kingham: It's a mix.
- 58:00David Kingham: Yeah.
- 58:01David Kingham: It's a mix.
- 58:02David Kingham: Um, it's things we've become aware of.
- 58:05David Kingham: Yeah.
- 58:05David Kingham: Um, and then, um, you start, you start to investigate in more detail and, and then you find there's a debate in the industry, are we gonna go to superconductors?
- 58:18David Kingham: In the next generation, or is it five or 10 years down the track?
- 58:23David Kingham: Yes.
- 58:24David Kingham: Um, and then you get some, some of the, so I mean, we couldn't go to market directly with a technology like that.
- 58:33David Kingham: We'd have to partner with an engineering player who's already supplying into that industry.
- 58:41David Kingham: Yes.
- 58:41David Kingham: Um, so some of those are very cautious, um, and very slow moving.
- 58:48David Kingham: Others, uh, are open to innovations Yes.
- 58:52David Kingham: That might come through to market in two or three years.
- 58:55David Kingham: Yes.
- 58:56David Kingham: So,
- 58:56Chris Reichhelm: yes.
- 58:57Chris Reichhelm: Okay.
- 58:58Chris Reichhelm: David, one final question for you.
- 59:01Chris Reichhelm: When do you think we're gonna have nuclear fusion reactors actually producing nuclear fusion?
- 59:08David Kingham: Uh, well, our, our ST 40 does nuclear fusion now every day, or, you know, most days.
- 59:17David Kingham: Um, but it takes a lot more energy into it than it outputs.
- 59:22David Kingham: Yes.
- 59:22David Kingham: If you're looking at electricity generation Yes.
- 59:27David Kingham: Then I think 20 35, 20 34, 20 35.
- 59:32David Kingham: Okay.
- 59:33David Kingham: For electricity generation at meaningful scale.
- 59:37David Kingham: Um, and I'd point to the US Milestone Driven Fusion development program and possibly a new Japanese program that might aim realistically at that, uh, timeframe.
- 59:50Chris Reichhelm: So within 10 years.
- 59:52David Kingham: Yep.
- 59:53Chris Reichhelm: Right.
- 59:54Chris Reichhelm: Well that's exciting
- 59:55David Kingham: from Fusion.
- 59:56Chris Reichhelm: Yeah.
- 59:56Chris Reichhelm: That's very exciting.
- 59:58Chris Reichhelm: David, I've loved having you.
- 1:00:00Chris Reichhelm: Thank you so much for joining me today.
