NASA has discovered that atmospheric methane in one of Saturn's moon was produced from a geological source and not a biological source which casts doubt on age old knowledge that crude oil was produced from mulched organics such as forests and biologcal things. There are new theories that abound that the earth naturally recycles excess carbon dioxide and other carbon in its atmosphere by having its oceans soak up the compound and when the carbon mixes with the ocean's hydrogen hydrocarbons are supposedly created--first as heavy hydrogen and even possibly petroleum. If the Earth truly has a geological process for replenishing petroleum oil naturally, how will this knowledge work for or against green design and tech for energy and power generation?
