Diesel's produce less CO2 than petrol cars – which is one of the reasons CO2 MISSIONS have fallen by 4.5% 2 years ago, 6% last year.
But global photosynthesis converts extra CO2 back into biomass within 5 minutes – sucking it from the air. All the Fossil Fuels were active life before the mass extinctions of prehistory converted their carbohydrates into deep coal.
A the geothermal water on the Earth's mantel bubble through that coal, Molecular Nuclear Fusion formed natural gas.
or we use the Sabatier equation published 1910, to unburn CO2 and natural water, at < 1 atmosphere
1a CO2+3H2O-P+T->CH4+He+O3+X-ray at 350oC – heat supplied by a steam plasma tube – see below
The O dissolves away in more geothermal water, the gas polymerised to form the Fossil Fuels
We burn the Fossil Fuels, we do more Molecular Nuclear Fusion
So oxidising the C radical takes in most of the heat. A 1m row of oil or gas burners only releases 45kW of heat.
A steam plasma tube does just the Molecular Nuclear Fusion
1.2MW from a 50x1cm steam plasma tube at 4 atmospheres.
So we do the obvious – we replace all oil and gas burners with totally emission free steam plasma tubes. Which use 10-12cc of regular water, per MW of heart for a year.
From regular, free water. Not 200,000 L of massively overpriced oil: that produces CO2 AND NOx. Not just diesel and petrol cars – all oil and gas burners.
NOx washes out of the air, as plant fertiliser – not a pollutant. A life booster: main source, natural lightening.
So DIESEL'S ARE THE GREEN, NON-POLLUTING Fossil Fuels engine. Not as good as a steam plasma tube though.
Interestingly enough, we can use a chemical plant to convert fracked gas and biodiesel into biopetrol. For 20% of the production cost of Fossil Petrol.
A carbon 0 fuel. As fracking converts non-fossil bacteria into methane, and plants take in as much CO2 to grow the diesel oil – as is emitted
And photosynthesis has capped global average CO2 at 2 parts per million – since before industry. The natural climate has been cooling for 21 years.
Now we can replace all fuel oil burning, with the 1,600 times more dynamic, free, non emissive Molecular Nuclear Fusion.
Incidentally, CO2 levels are higher above the Arctics, or the fossil record shows, in an ice age.
