Run cars on hydrogen (waste products = H2O = water).
Yeah I believe that is the future.
Electric cars won't ever be popular. 12 hours or more to recharge just won't cut it.
And hybrids are really disappointing. They would make sense if they got 50 miles/gallon or more.
With a "Manhattan project" for hydrogen fuel cell cars it could happen. Gotta get the infrastructure in place for refill stations and the car companies need to be on board also.
There are still some things to iron out. Cost and reliability at high and low temperature are a big problem now.
Most people don't realize that hydrogen fuel cell cars are electric. But it's like a battery that never goes dead as long as you keep feeding it hydrogen. But as of now a lot of the parts won't last very long. And they are still expensive to replace.
