Abstract

The method and the device for production of heat and/or electric energy with a geothermal gravitational heat pipe (1) according to the invention allows use of thermal energy of subterranean rock for production of heat and/or electric energy. Geothermal energy of subterranean layers of rock is exploited with the geothermal gravitational heat pipe (1) so that liquid working fluid is lead into the pipe for vaporization due to the geothermal potential of subterranean rock and the generated vapour is led to the surface. According to a first embodiment the working fluid vapour are used for combined production of heat and/or electric energy. According to a second embodiment, working fluid vapour led from the geothermal gravitational heat pipe (1) to the surface are used for production of electric energy. According to a third embodiment the working fluid vapour led from the geothermal gravitational heat pipe (1) to the surface are used for production of heat and to a lesser extent for production of electric energy by the optional variable phase turbine (20).
