Aviation is becoming a backwater of technology. They still use leaded gas for piston planes. Their answer to global warming is to make ‘green’ jet fuel by using painfully slow and expensive Fischer-Tropsch chemistry to build up hydrocarbons rather than switch to something reasonable like alcohols, dimethyl ether or methane. Ground transportation is 20-30 years ahead of aviation in terms of sustainable fuels but in the backwater of aviation they are too afraid to make any changes at all in fuels. |
