Woah that's interesting. So they wouldn't be opposed to something like kite power, if you could turn the electronic software control program into a mechanical "clockwork" style mechanism.

And the invention of a grid storage battery that is circular / fully recyclable would be great too. But obviously there are already solutions like nickel iron but they aren't that efficient.

Genetically engineering a plant that is ultra efficient in producing a biofuel would be great. Ideally a bush that doesn't have to regrow and doesn't need to be replanted every year, but produce oil for diesel motors. Or some biofuel that can be used in a fuel cell, if you can build a simple fuel cell. Ammonia fuel cells maybe. (Sorry just a bunch of fancy ideas lol)
