“Well if we had a brain, we’d have nuke plants coupled with desalinization and electrolysis.”

Hydrogen is still very difficult to store or ship. So there would never be a large hydrogen production plant coupled with a nuke plant. Now, it could be argued that nuke plants could provide cheap electricity, which is easily shipped to our homes...and we could use ‘in home’ electrolysis set-ups. However, just speaking for my own personal situation -the cheapest power in my neck of the woods (eastern Kansas) is coal. We have a nuke plant, and the power from it costs more than the coal plant.

Any 6th or 7th grader can separate oxygen and hydrogen from water for their science fair project. Easy. What's not easy is either compressing the hydrogen, or liquifying it (less than -400F). So good luck just pulling into home and refilling your car!
This process generally requires about 30% of the energy stored in the hydrogen, as well as lots of equipment to actually do it. Not something most people can just use or even afford.
