In the 1st image with the molecule in yellow did you see…
CO V Fe Fe
CO is carbon monoxide. It comes in to an Iron atom (Fe) which acts as a kind of catalyst. Electrons come in to a Vanadium atom (V) sandwiched between the FeFe ligand.
Water and or Hydrogen ions come in via another Fe atom and the .molecular machine constructs methane or ethane, the fundamental components of petroleum.
Remember when Trump tried to tell you this in a tweet? This is why Saudi capitulated. Their control of oil production is based on lies and fantasies. Oil is everywhere in ABUNDANCE!!!
Although the molecular machine above is Vanadium nitrogenase, an enzyme that could be used in moon colones or on a starship to manufacture petroleum, a similar chemical reaction mediated by a FeFe ligand and Vanadium is happeningDEEP DEEP Below usin the earth's crust, all around the planet in the Deep Hot Biosphere. You see,Petroleumis not a fossil fuel at all. It is a renewable resource that is abundant under the ground and in many places it oozes to the surface on its own. La Brea tarpits are one notable example.
This is the reason why Saudi Arabia has invested heavily in high tech, like water desalination plants for instance. They know that their oil is practically worthless. However their technology to live and thrive in a hostile desert environment will be worth a lot as we build mining colonies on the moon, farming and terraforming colonies on Mars, and the zero-G colonies in the asteroid belt where the generational starships will be built inside hollowed out asteroids. These ships will be self sufficient not even needing a sun to grow their crops and raise healthy livestock.
