thanks for the tip about the honda dealer. im prob not going to be able to afford my own car for alteast another decade (hopefully lesser). but we get loads of cars with cng kits fitted in them, even though thats not the same thing.
while methane seems like a viable alternative to oil, it would still need to address the big question - how efficient is it as a source of fuel? i read up a little about methane hydrates on the web and learnt its becoming popular even though its drilling is a potentially dangerous process.
but in the long run, we still need to shift to energy sources cleaner than methane and natural gas. currently, methane and other non-CO2 gasses make up for 40% of green house gasses. and..."undersea landsides triggered by volcanoes that occurred more than fifty million years ago resulted in the release of methane hydrate, contributing to global warming that lasted tens of thousands of years"
