I don't know much about TTEG, but they describe it as a "turbine" engine. Which means it takes air, burns it, and uses the combusted gases (now more voluminous) to produce rotation.

The Cyclone engine uses combustion (or any heat source) to vaporize water which is circulated in a closed-loop. As a result of this abstracted heat source, it can utilize pelleted fuel in addition to liquid and gaseous fuels. It could even conceivably use solar. Furthermore, the fuel quality isn't a narrow specification. As long as it burns above a specific temperature, it'll work. Typically turbines use kerosene. The Cyclone can use that, or even raw oil.

Because of the closed-loop, it is possible to use it provide heat from the condenser coils the same time it is producing rotational energy. This could be used for radiant heating, hot water heating or general heating, all the while the rotational energy is producing movement or electricity.
