Powdered coal fired turbine powered Eldorado

It's an older article, but I hadn't seen this posted yet.

Minor problem. I don't smell like gas after filling up my tank currently.

Me either, but thats like twice a month I do it.

Mr Diesel tried coal dust first with a piston engine and was nearly killed. You think something better could of been done like use the actual coal rocks and grind them on the fly? I mean how would you buy coal powder and refill the car if it was a reality?

Unless you make/sell cement!

Do you think this stuff could be 'pumped' like liquid gas to avoid the chimney sweep look?

Yeah...... turbine powered vehicles are not the best performers in sudden acceleration. THey used a gear reduction vs hydrostatic drive or a hybrid set where hte rear wheels are driven by an electric motor and the turbine powers a generator.

So, to those people who say that electric cars are not free of emissions because 'where do you think that electricity comes from? A coal burning power station!!1!11!!' you can point to this as the alternative and ask them to guess if it's any less, or more, free of emissions.

At one time around the late 1970's, the Union Pacific Railroad spent big bucks on an experimental coal fired turbine locomotive. The logistics of grinding up the coal was overcome but the fly ash and the turbine blades did not play well together. With no easy fix in the forecast, a good idea was finally sold for scrap.
