Air Fuelled Car and Petrol from Bacterial Action

Sometime back it was in news that engines can be built to use CO2 from air, Now from air and bacterial fuel.
I quote from TOI,
” Markus Ribbe, a scientist at the University of California, says that eventually the enzyme could be tweaked, so that instead of only making the simple three-carbon-atom chain molecule of propane, it could create the longer chains that make up petrol. “Obviously this could lead to new ways to create synthetic liquid fuels if we can make longer carbon-carbon chains,” says Ribbe.

The researchers found that, when deprived of the oxygen and nitrogen from which it made ammonia and given carbon monoxide instead, vanadium nitrogenase automatically started using it to produce short carbon chains, two or three atoms long. Cars produce carbon monoxide in their exhausts through incomplete combustion, so in the not too distant future, it might be possible partly to fuel cars off their own fumes. Later still, it might be possible to draw fuel straight out of the air.”

Fuelling future: Soon, cars to run on thin air

Researchers say that car fuel could be created from air using an enzyme from a common soil bacterium. It is hoped that this will lead to a cheap way of making environmentally friendly, carbon-neutral “green” fuel that can be used without major redesigns of car engines, reports Discovery News.
Azotobacter vinelandii, a microbe found around the roots of various food plants, creates an enzyme — vanadium nitrogenase — which in nature produces ammonia from nitrogen gas. But now it has been shown that it can also create propane, — a common byproduct of industrial processes.
