A rotary heat engine is a Rankine cycle (temperature difference power generation or binary power generation) with an external combustion type Bankel type rotary engine (expander) developed by us. Since the Rankine cycle operates around the boiling point of the working medium, it can generate electricity from a low-temperature heat source when a working medium with a low boiling point is used.

The Peltier effect is normally used to pump heat. By combining two Peltier modules in a dual layer, large temperature-differences can be measured. As a result, more electricity can be produced more efficiently.

(Patent is pending)

We use both Peltier and Seebeck effects in our two-stage Peltier devices, and we are entrusted with the thermal design of these devices.
