I started with some sugar, imagine just like a marshmallow and we can grow sugar so there’s plenty of it. Then I turned the marshmallow into some black carbon foam; a bit like ash from a fire but with lots of really, really small holes in it. That could be used in electric cars when you slow down to put some electricity back into the battery.
