Cheap petrol and gas


In 1910, scientists worked out the Sabatier reaction.
1 CO2+2H2O+E+T->CH4+2O2 at 1 atmosphere
When we have low pressure gas, it burns with a sooty black flame. So we usually want 4 atmospheres. At 1 atmosphere and 370oC, we get the opposite reaction: the wonders of thermodynamics.
So we have a power plant (more on this later) with condenses CO2 out of the air. 0OC at ten atmospheres.

And we drill down to a magma chamber, over 10m down - all over the Earth. At 34m down, the steam comes up with gold powder – so we need a Dyson dry cleaner to seperate out the gold, platinum, silver and copper dust. Gold all over the Earth.
Gold is the 5th most abundamt element on Earth – but concentrated in the deep. Geothermal water brings it up. All over the world.
So we get out methane and oxygen at 360oC. We use a semipermeable membrane to separate these explosive gases – only Cu metal components until we have the gases separate.
They go through 2 turbines, to generate 580kW of power. We drive yet more Carnot systems to produce liquid oxygen.
The methane we pass down 8 layers of titanium honeycombs. And me polymerise the methane
2 CH4+(Ti)-+PO+T->CmHn n=m+2 m=16 for petrol, m=12 for diesel. We do not use up the Ti catalyst.
This is why we pressurise petrol and diesel before use – as it will not burn at low pressure. Diesel spontaneously combusts above 8 atmospheres. Petrol will diesel at 10 – and give out more energy.
So we get out methane – natural gas. We can sell, and when burnt, we get back to CO2 and H2O. And almost free petrol and diesel.
Bet done in tome – as plants turn extra CO2 into plant biomass within 5 minutes. So no Fossil Fuels extraction – that is just too expensive.

And making petrol from CO2 in the air makes it a 0 carbon fuel. Uranium fission needs oil above $100 a barrel to make money. Today it is below $50.
