We should be able to increase jet speed by a factor of ten – so reducing their carbon footprint by the same amount. We start a jet off with aviation fuel. But then we use the exhaust manifold to boil off water.
We use this steam in place of combustion fuel – and turn off the aviation fuel. A present jet doe Molecular Nuclear Fusion
Plants on the land and sea take in the extra CO2, to covert it back into biomass – the Jurassic had 65% more active life than is on Earth today. So leaving a pre-industrial 2 parts per million CO2 in the air. A static trace gas affects NOTHING. GW=0 out of 10 fiction. As is climate change – the world has cooled since 1995.
So we run our jet plane off very little water – only burning aviation fuel at start up amd landing.
So we save life on Earth – and a lot of money. You believe in CC? Seek help for your untreated mental health problem.
