This is the future of course, fusion power to generate electricity, and then converting electricity into food somehow.
Hopefully without going through photosynthesis, which feels complicated and wasteful.

Previously known as "Food From Electricity", "NeoCarbonFood" sounds like a more commercializable version of it.
Uses electricity to electrolyse water into hydrogen and oxygen molecules, and then use bacteria that do hydrogen chemosynthesis to convert it into food.
