The invention relates to a method for converting thermal energy, in particular energy from the environment, into kinetic energy and to a device for converting thermal energy into kinetic energy, said device being used to carry out the method. In the method according to the invention, two circuits with fluids are operatively connected together in that on at least three heat exchangers, one fluid influences the others. The two circuits are additionally provided with environmental heat exchangers which preset the temperature of the fluids being used. The exhaust heat used for this purpose can originate from the industrial sector for example.

Techniques for cogeneration of heat and power are disclosed. A cogeneration system includes: a conduit loop configured to carry a working fluid using a Rankine cycle; a valve system disposed along the conduit loop, including valves configured to manage flow of the working fluid through a chamber; a backflow vapor line disposed along the conduit loop, configured to direct working fluid in a gaseous state to the chamber, such that the working fluid in the gaseous state displaces working fluid in a liquid state in the chamber and the working fluid in the liquid state advances through the conduit loop without requiring a mechanical pump; and a heat exchanger disposed along the conduit loop, configured to extract heat from the working fluid and direct the heat to a practical use.
