There are companies that produce hydrogen with fuel cell as back up fork-lifts, buses, cars etc. The cost of hydrogen compared to gasoline is slightly higher, however the car, fork lift, or other mobile gets much more bang for the buck, A car would get more mileage, practically twice the mileage, and there are buses in Europe running on hydrogen right now. Would you be okay with the investment for the necessary infrastructure? Search yahoo.finance for hydrogen and fuel cell companies to learn more. Zero emission aside from water vapor and heat. I think this has to happen, would you support a change in energy sources? Cheers!
