Answer 2

I would like to see external combustion engines restored to use. Let people shovel in coal to increase their speed.  

And the wrecks would be AWESOME!

Answer 3

Waste water. Or politicians' hot air.

Answer 4

Algae Fuel!  

Algae fuel, also called algal fuel, oilgae or third generation biofuel, is a biofuel from algae. Compared with second generation biofuels, algae are high-yield high-cost (30 times more energy per acre than terrestrial crops) feedstocks to produce biofuels.

Since the whole organism converts sunlight into oil, algae can produce more oil in an area the size of a two-car garage than an entire football field of soybeans.

Algal fuels do not impact fresh water resources, and can use ocean and wastewater.

Answer 5

electricity produced from nuclear.  That said, nascar will just not be the same.. no muscle cars... no noise... no smell of fuel.. just a bunch of golf cart-like vehicles quietly running around the track..

Oh how depressing... where's the prosac

Answer 6

bike pedals or flinstone powered cars are one thing I would like... or an air compression system where a midget sits in your trunk and punches an air bag to make your car move.

Answer 7

I'd prefer synthetic hydrocarbons produced from water and CO2 taken from the atmosphere (so that when they get burned the CO2 isn't added but merely put back) along with energy from Gen IV nuclear reactors using an efficient thermochemical process (more likely set of processes, getting hydrogen by the Sulphur-Iodine process will probably be one of the first parts of it).

Synthetic hydrocarbons have the advantage of being a cleaner version of what is currently put in cars meaning that the existing vehicle fleet could start using them as soon as we can make them without anyone needing to buy new cars.

Of course for it to be worthwhile you need to get your energy from something other than coal (and it'd be better to get the carbon from something other than coal as well) which has been traditionally used for synthetic fuels.

Answer 8

when you have a car+motorcycle that runs on others i will be interested but till then  still going to use petrol ..... but am puzzled to y they don't use more of the methane we produce ... IE cows c**p ...and rubbish tips produce lots of it every day ...

Answer 9

electrical..which produces nothing but water out the tailpipe....we live near a wind farm that produces electricity

Answer 10

For me, I'd like to see something that uses water.  I wish water could power up cars, since we have plenty of it.  Plus global warming is melting the ice around Antarctica and colder parts in the world, so the ocean is getting bigger and bigger.

Answer 11

I would most likely go for compressed air.
