an idea
Strain out the bad stuff
Well... an idea I have is that if we could put a carbon dioxide filter in the muffler like they use in the power plants then it would reduce the level of carbon dioxide in the atmosphere. just a thought?
Barry's Response - Might work. If you can get a big enough filter. More than half the weight of each tank of gas is pure carbon, and when it combines with oxygen to make CO2, its weight more than triples.
Kinda poses a problem.
