we make the hydrogen by using electricity to crack water (we make the electricity by burning coal)https://twitter.com/alexriesart/status/1426485113320218624 …

4/ Nuclear is a great power source, but if you have unlimited electric from nuclear, you should use that to create a hydrocarbon from atmospheric CO2. Hydrocarbons are much better energy storage fuels than raw hydrogen.https://twitter.com/alexriesart/status/1426532898446876672 …
4/ Hydrogen has one thing going for it: it has high energy density PER MASS, so if you're trying to finesse the rocket equation (where at t=0 you're lifting all of the fuel for t=1...n, and at t=1 you're lifting all the fuel for t=2..n, etc.), it's a win.
5/ yeah, "solar to hydrocarbon" (i.e. growing corn) certainly works. But I was specifically going down the nuclear route, bc you get much higher energy generation per acre that way. A society that grows corn for all energy uses is a sad one, IMO. https://twitter.com/ITBeHa/status/1426533874386055171 …
