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.

Rim-driven thruster Rim-driven thruster Rim-Driven Thruster is a novel type of propulsion unit which was presented at the Shipbuilding, Machinery & Marine Technology 2010 trade fair (SMM) by the companies "Voith" and "Van der Velden". The Rim-driven thruster is a marine propeller which does not need a hub for transmission of the driving torque. Conventional propellers need a shaft line which is driven by a turbine, a diesel engine or an electric motor. The more recent podded drives consist of a conventional propeller which is arranged together with a conventional electric motor into an azimuthable gondola under water. The blades of the
