If the EESU works and is going to be out soon, that could be promising. As long as the infrastructure can be decently upgraded to support it anyhow. For the US, the bigger problem is going to be covering the massive amounts of highways with enough places to charge up. There also needs to be a way to deal with a vehicle that runs out of power miles away from a station.

The same challenge of course exists for hydrogen, but I do think it has a better possibility for the future. Anyone know what would be involved with changing over existing gas stations to also have hydrogen storage? To me, I'd imagine it would be simpler then the electric infrastructure needed to support all the existing filling stations to power everyones EESU powered vehicles.
