The main idea of global warming is that greenhouse gases prevent the energy from leaving the surface of planet. In the same time the upper layers of the troposphere are much colder and successfully emit the infrared radiation to the outer space. So to stop the global warming it is necessary to organize the moving of the heat from the lower layers of the atmosphere to the upper layers.
Also we know that the heat engine performs the conversion of heat energy to mechanical work by exploiting the temperature gradient between a hot "source" and a cold "sink". So the moving of the heat from the lower layers of the atmosphere to the upper layers can be done with some output of the mechanical work. The amounts of this mechanical work can be huge as we know on example of a tropical cyclone. The working body of the cyclone is simply the moist air, which releases the heat by water vapour condensation when rises. So to make the atmospheric heat engine it is necessary to make the construction in which the moist air is circulating in organized manner between the lower and upper layers of the troposphere. Therefore the height of this construction has to be about the height of the troposphere. Also this construction has to be able to withstand the strength of the winds. These requirements can make the creation of such constructions too expensive and non profitable. To solve the construction problems of the atmospheric heat engine the present synopsis suggests to use the principles of the hot air balloon. If the moist air, which is the working body, will have the average temperature, which is higher then the average surround air temperature, then the atmospheric heat engine will be buoyant. In this case the powerplant will travel with air and it will not be necessary to withstand the winds. Also in this case the construction will be as light and cheap as possible for such a device. To get the additional energy to keep the average temperature difference the atmospheric powerplant can convert some part of produced mechanical work back into the heat energy. Also to minimize the necessary temperature difference the device can be constructed as Rozière balloon which has separate chambers for a non-heated lifting gas (such as hydrogen or helium). To decrease the size of the device it can be made in shape of thin long vertical thread of pipes. The central pipe will deliver the cooled air down and the peripheral pipes will keep the hot air, which moves up. Such a thread will spin because of Coriolis effect in the same direction as the tropical cyclone. Also it will produce the upward current because the peripheral pipes will heat the air in the upper part of the thread. As a result the thermothread will organize the local weather pattern around itself. The upward current will produce the precipitations and as a result the conditions on the ground can be improved and the amount of water vapor in the atmosphere will be decreased. As the water vapor is the main greenhouse gas then such a device will decrease the reasons of global warming. Also the upward current will obviously move the heat up to the layers, which are less covered by greenhouse gases and so can emit this heat by infrared away from planet. So the main idea consists in fact that we use the gradient to get some energy and then use that energy to create the weather conditions, which in their turn will use the same gradient. Thus the device will work as catalyst of the weather which will increase the heat exchange between the surface of the planet and the upper layers of troposphere. The design is not monstrous, it is only 10-15 km length system of light air pipes. For example, the small town of 100 000 people can have 100 km water pipes.
