Why aren't we using methane to power our vehicles? Global warming is here and the effects are presenting themselves in the arctic with the permafrost melting and the oceanic clathrates. Why not use it to help? I have read of a farmer who collected the methane from cows to heat the milking barn in the winter, so it can be done, the science is there.
In the book, "The Long Emergency" by James Kunstler, the author advises us that we have peaked in our oil exploration and production. It's all downhill from here folks. Methane is a light hydrocarbon just a few less atoms per molecule than oil. With the global warming advancing on us, we going to be dealing with this anyway,so let's make the best of it and perhaps delay the end of our species.
