Another alternative to electric, is Hydrogen. HHO generator kits are available now.
There's plenty of information online about this subject.

A hydrogen-boosted petrol engine is said to have more efficient combustion, (more air)
i.e., more power....and at least 20 to 30 percent improvement in fuel-economy.
One company claims to have developed a bolt-on style 'Reformer',which makes the
hydrogen from gasoline and only takes 75 watts to run.

Or you could go all the way and run completely on hydrogen from water alone.
It's not too hard to imagine a "Beddie Bubbler".
Probably rust out a few exhaust pipes though.
