Put a cow in your tank!

Methane produced by livestock waste is a serious greenhouse gas--much stronger than CO2--that makes a big contribution to global warming. Cattle-rearing alone creates more greenhouse gas than cars!

But methane is great fuel. Hm [scratches head]. What to do?

Apparently, it's really easy to capture biogas & put it to immediate use on very small scales--you don't need massive plants & storage facilities...just a rubber inner tube.



And while you're at it, why stop with animals? I once suggested this self-supplied fuel source to an arctic explorer, but he didn't seem too enthused.
