Well, compressed air. Check it out: http://www.flixxy.com/zero-pollution-automobile.htm
"has zero pollution"
"it costs nothing, nothing to fill up your car with gas"
Errr - so who's paying for the air compressor, and how is it powered.
It goes on to talk about driving a compressor....with a compressor and actually uses the words perpetual motion.
I assume, therefore, this is an Onion like spoof? It certainly isn't based in reality.
I think it's more like the guy who wrote the narration had no idea what he was talking about.
This is a pretty interesting concept, my grandpa was telling me about this a little while ago.
The more things change the more they remain the same...
Railway locomotives that ran off compressed air have been around for over 100 years. The Eckington System in Washington, D.C. began using ten compressed air street cars in the late-1890s.

I love how old ideas are recycled into new. This idea is at least 100 years old. Steam trains couldn't be used in fire-sensitive areas such as munitions works, areas with coal/flour dust, so they converted steam trains to run on compressed air. I remember seeing on in the Museum of Transport, Glasgow, in fact, here's a picture of it!
Have to watch a lot of the "zero pollution"claims, such as hydrogen or electric power, as it's only zero pollution at point of use. Only zero pollution if they then build more renewable or nuclear power stations.
Yep, the compressed air powered car has been around for a while as has the water powered car (including steam driven cars). The conspiracy nuts will tell you that the oil companies have been squashing such ideas for decades.
You consider nuclear power pollutant free?
If everything goes right, it is.
It's just that things could go so horribly wrong.
no emissions? what about the coal energy it takes to compress the air or to power the generator?
Yes I do, to the same extent that I consider hydro-electic to be pollutant free. Except that to manufacture 1 tonne of concrete you emit about 1 tonne of CO2 and you need an awful lot of concrete to build a hydro dam (and for that matter, a nuclear reactor!)
But CO2 is a green gas and needed for the cycle of life on this planet.
So is Oxygen, but too much is toxic...corrosive...and nasty stuff.
Oxidation is nasty stuff, and yet its element is what we need to stay alive.
