Our cars all run on Oil, which is limited resource and shows signs of ending.

This makes urgent to develop policy to fuel our cars using something other than limited oil.

But american public and politics seem especially idiotic and their choices - proposing alternatives (and spending money on them) that clearly wouldn't work - or waiting some mysterious inventions.

a. Hydrogen

b. Corn Ethanol

c. Algae fuel, Celulose ethanol - no working technology yet, big question if it can be done.

d. Electric cars - limited, range, expesive, uses lot of electricity, In my opinion main problem - takes a lot of time to charge. especially if you compare with 1-3 minute to fill gas tank.
