If you could use anything as fuel for a car what would you use

Question

I would chose glass because a lot of it is in landfills

Answer 1

Hydrogen. It is one of the most abundant elements in our atmosphere, and when it's combined with oxygen and burned, the only byproduct is water.

Answer 2

i would use nitrogen from the air or  cold fusion.  

Answer 3

Pidgeons as there is no other use for them and would give me an excuse to kill them.

Answer 4

Glass is a natural product, just sand under a lot of pressure.  I'd choose water since there is an abundance of it.  Also, if we needed clean water to run our cars maybe we'd start taking better care of our water supplies.  Plus, what would burn cleaner than water?

Answer 5

I would use non-recyclable trash such as food scraps.  Glass would be a good start, but once you exhausted all that was in landfills, it would take too much energy to make more to fuel all the cars, and glass should be recycled so we don't have to make so much more.
