That’s not sci-fi—it’s SolCold, and it’s the kind of “impossible” physics that only becomes real when someone refuses to quit.

When Yaron Shenhav was a master’s student in electronic engineering, he couldn’t shake a paradox: why do we burn energy to create cold? That thought—plus an overheated apartment—sparked a decade-long obsession that became a new class of nanoparticle coatings. These materials…
