please tell me where to buy the methane gas tank. It will be deeply appreciatied.

Thank you very much

Could a family of four produce enough methane with a compostable toilet and a fuel cell electric generator to get off the electrical grid. How do we capture the gas to utilize it.

Green energy is definitely the best solution in most cases. Technology like solar energy, wind power, fuel cells, zaps electric vehicles, EV hybrids, etc have come so far recently. Green energy even costs way less than oil and gas in many cases.

The estimated 5.3 bn gal of gasoline replacement through methane just from cow manure alone give us an idea of the potential (we are at maybe 5-7bn gal of Ethanol right now). One of the issues around methane is naming. We call it natural gas, methane or biomethane or biogas which confuses one and the same thing. On that note there is existing infrastructure that is currently used for CNG and LPG cars (especially in Calif. where there is nil E85). Methane/biogas could just run through that.

Thanks Jim, interesting thoughts. We tweaked that sentence to make it a bit more clear.

Biomethane is definitely the least appreciated biofuel. I think this is a mistake because it is probably the best overall choice. It's much cheaper to produce NOW from cellulosic and other waste streams, than cellulosic ethanol ever will be.

I think the author meant to say: "They start with methane and use the traditional gasoline fuel..."

As for the 1,000 methane stations in Europe, how does that compare with E85 stations? Or Hydrogen stations? Perhaps the infrastructure is not so bad. Definitely something one could build upon.

Methane (especially dense-storing methane) combined with PHEV technology could form a great core technology base from which to affect serious reductions in oil use for transportation.
