Power plants that convert temperature differences into mechanical energy have always been in demand. Alexander Bariskin, a designer from Sverdlovsk Oblast, proposed his own design for such a rotary engine.
According to his idea, the design uses a rotor partially submerged in liquid. It features two types of sealed modules connected by gas channels in a closed loop.
Some modules pass through a heating zone and increase the pressure of the working gas. Others are outside the heating zone and can change volume under the action of this pressure.
When the gas heats up, its pressure increases and is transferred to the second module. This module expands, increasing the displaced volume of water and gaining additional buoyant force. Since the connected modules are located with an angular displacement, a difference in moments arises, causing the rotor to rotate.
After leaving the heating zone, the gas cools, the pressure drops, the volume of the second module decreases, and the cycle repeats.
However, the unit does not operate without an energy source. As a heat source, Bariskin suggests an infrared emitter, a solar concentrator, or a heat-transferring casing.
The resulting rotation can be used to drive a generator, pump, compressor, or other mechanism. The developer emphasized that the scheme allows for dispensing with an external drive, compressor, and complex working gas control system.
Previously, Georgy Vasiliev, a developer from Kazan, proposed a closed thermodynamic cycle engine design that does not use atmospheric air as a working fluid.
