Maybe in terms of CO2, but turbines also don't burn as completely as most piston engine cars. 10k is probably an exaggeration , but the pollution is much worse

Maybe in terms of CO2, but turbines also don't burn as completely as most piston engine cars. 10k is probably an exaggeration , but the pollution is much worse than the fuel economy indicates. Similarly, my chain saw probably pollutes nearly as much as my new Honda truck even though it only gets a few gallons of gas per year.
