Ups: It's really cheap, No replacement or modification of your existing diesel engine. Downs: Yet to be Commercially Available. There are other ethanol and oil based biodiesel variants available in some parts of the UK and the USA. But to use them, you've got to modify your existing diesel engine. Biodiesel from Jatropha.

I think nuclear power would be very interesting, but it's too scary still and would have to be huge to safegaurd the fuel cells.

Ethanol can not begin to replace gasoline. We are burning something like 9 million barrels of gasoline each day. An acre of corn can only produce about 4 to 5 barrels of ethanol. I don't think there are enough acres in the US to meet the annual demand. I believe hydrogen as a fuel to burn in conventional engines is at best a break even deal. It takes as much energy to make the hydrogen as the amount of energy you get from the hydrogen. The cost is more in the alternative fuels. Ethanol can not begin to replace gasoline.
