I doubt the goverment will like this, it would catch on they know this, this techonlogy with funding would work, like the internal combustion engine it would start off rubbish and move to a revolution.

Therefore I reckon the only reason this won't become the next big thing is simply due to tax, the goverment makes a killing out of taxing the fuel prices, and loosing this nice source of revenue...I seriously doubt it.
