Lightcell: An engine that uses light to make electricity

thanks to curl-up who posted this, whoever you are.

since it came up, "wire-to-wire" efficiency is what I intended to coin a synonym for electrical to electrical efficiency, with hydrogen storage. for example, an 80% electrical to hydrogen efficiency, and a 50% hydrogen to electrical efficiency, would yield a 40% wire to wire (electrical to electrical) efficiency. of course, people are working on 95% electric to hydrogen efficiency, and 50% fuel to electrical efficiency is a target.

here's an illustrative energy flow diagram for us trying to hit 60% -- even more aggressive. https://x.com/DanielleFong/status/1775595848887677138
