A very likely future fuel is hydrogen. A reverse electrolysis system is used to convert water into the useful hydrogen. While hydrogen has dangerous qualities, it is actually safer than gasoline. It takes more pressure to combust; it burns at a lower temperature than that which burns skin.

It can be safely stored in special tanks, either at the bottom of the car or in the reservoir. It is also possible to produce it on-site in fueling station. Presently, there are ways of using air as an energy source. Compressed air currently gives 200 miles on one tank; three tanks are found on some models.
