There is no doubt that fossil fuels CAN be replaced. Virtually every
diesel on the road today can run on a bio-diesel fuel. Every car could
run on pure alcohol. Of course, gas turbine and turbojet aircraft can
fly on almost anything flammable, piston engine planes could also use
alternatives. All it takes is the motivation to change. Eventually the
cost of extracting petroleum will provde that impetus.

OK then, would you please enlighten me as to why any of these assertions
are impossible?


Known thermal efficiencies of Otto and Brayton Cycle devices
Energy densities of alternative fuels
Excessive secondary emisive biproducts of alternative fuels generation
Fuel handling safety issued with the general public
Limited supply sources for raw materials of bio fuels
Incalculable infrastructure changes
... I could go on...


Leave song writing to the dreamers. Leave science to the engineers.
Oh, and yes, I am an engineer.
