Gas turbine locomotive turbine locomotive to be used on British Railways. The locomotive was to be built by the North British Locomotive Company and the turbine would be supplied by C. A. Parsons and Company. According to Sampson, the plan was to use indirect heating. The pulverized coal would be burned in a combustion chamber and the hot gases passed to a heat exchanger. Here, the heat would be transferred to a separate body of compressed air which would power the turbine. Essentially, it would have been a hot air engine using a turbine instead of a piston.

Smith-Putnam wind turbine Smith-Putnam wind turbine The Smith-Putnam wind turbine was the world's first megawatt-size wind turbine. In 1941 it was connected to the local electrical distribution system on Grandpa's Knob in Castleton, Vermont, US. It was designed by Palmer Cosslett Putnam and manufactured by the S. Morgan Smith Company. The 1.25 MW turbine operated for 1100 hours before a blade failed at a known weak point, which had not been reinforced due to wartime material shortages. It would be the largest wind turbine ever built until 1979. The turbine had two blades, 175 feet (53 m) in diameter, on the down-wind side
