A deep sea hydrocarbon factory

Fringe geologists have been positing for some time that there are sources of non-fossil "deep gas" in the earth. Now a mechanism has been discovered that creates methane in a non-biological process. If the process can be duplicated, we can synthesize methane and there may continue to be life after the fossel fuels run out. Or we may be able to tap the earth's crust more efficiently and get a virtually inexhaustible supply of gas.
