I have heard of harvesting methane as a different alternative fuel. How would they do that? I have read that they take the leftover parts of animals at the meat packing companies and place it in a vat containing enzymes that, at constant temperatures, break the waste into a form of a soup. This soup is fermented for 30 days in this vat and constant temperatures to help create the methane gas. The methane gas is then captured and stored for use in different manufacturing facilities for different reasons.

I have also read that methane is produced by cattle worldwide and that it is eating our atmosphere and causing the highest amount of greenhouse gasses.

I propose this as a different way to power automobiles: You could take some piping from the fuel management system from your vehicle and lead it to the passenger compartment. From there, link up to a manifold system in which there are equal numbers of inlets to the available seating capacity of the vehicle. Place funnels under all available seating and connect them to the manifold. Instant methane burning!!

And with gas prices fluctuating like they do, you could always count on Taco Bell and White Castle to keep their foods at a respectable level.
