It stays liquid the whole time. So you could circulate it to charge it up, somewhere other than where you want to extract the energy. But it looks like it charges from 300nm light (UV) so depending on its absorption bandwidth usefulness is questionable. permalink fedilink source parent hideshow 4 child comments replies: [–] Bluescluestoothpaste@sh.itjust.works 7 points 6 months ago (2 children) There's plenty of sunlight energy at 300nm, even if most of it is in the visible spectrum. permalink fedilink source parent hideshow 2 child comments replies: [–] fullsquare@awful.systems 6 points 6 months ago it's transparent too so you can just put pv panel underneath to capture the rest permalink fedilink source parent [–] m0darn@lemmy.ca 2 points 6 months ago* (last edited 6 months ago) I suspect it's sensitive to only a narrow band of frequencies, akin to the molecule's resonance frequency, but idk permalink fedilink source parent [–] fullsquare@awful.systems 2 points 6 months ago there is a problem that it can heat itself up so hard during decomposition that it can just go on without catalyst permalink fedilink source parent
