Amazing stuff.
Most vehicles stay parked for at least 12 hours a day. The average American vehicle is driven 35 miles a day. A standard 15A 120V outlet would do fine. They can also be set to only draw power during off peak hours when electricity is cheap and plentiful.
I think running a few dozen feet of wire is easier than inventing a new kind of fuel.
Most people don’t live in the US, also a lot of people don’t live in single family homes and park on the street. No garage means you need to install lots of on street chargers.
Which amount to basically extension cords with relays. All the tech for charging is already built into the vehicles. Most people could live happily with just 20A at 240V.
I don’t see how inventing and rolling out the infrastructure for an entirely new kind of fuel/energy storage tech is easier than just running some more wiring. If they charge at night when the office building/apartment/transit energy use is minimized, it won’t even put that much strain on the grid.
And you get to keep all the existing benefits for single family home people. Sprinkle in some vehicle to grid, and it gets even better.
