So these stations would have to have solar panels, some sort of windmill to capture wind power, and a diesel generator that runs on alternative fuel. And that's just for the electric cars.

Cars that run on other sources of energy would need a dispenser and storage tank for each type of energy.

This refueling station is getting bigger and bigger... or are you thinking of having a different station for each type of alternative fuel?

Another thought: using food sources as fuel sources will make food more expensive. I think we need to use non-food sources as fuel sources. Lawn clippings come to mind, but I think that would take too much energy getting it from yard to "refinery". Anyone else have any other ideas?
