Then, heat can be considered as chaotic motion result. So, in the second case kinetic energy is transformed in kinetic chaotic energy. This conclusion allow to make the proposal for some scheme, Fig.9. I am grateful to Academician V. I. Zubov, St.-Petersburg, for useful discussion on this topic. The device that use heater that create the reactive flow and cooler to transform the heat energy of this flow in other form of energy to return it in the heater.
System can use reactive flow of mass in closed asymmetrical cycle to create the propulsion force.
This flow is moving back from heater with some kinetic energy and at the moment the body of the device is getting some corresponding reactive impulse. The difference in total right and total left impulses produce the propulsion of the system and the temperature gradient inside of the system. It is possible to say the system is moving by means of the inner temperature gradient. Note, that many ancient Indian papers described flying device that use mercury in closed cycle to produce the propulsion force. For this mathematics it is necessary to use time directed four-dimensional vectors of impulse, force, electric field intensity and so on.
