Filed: 2013-10-31
Abstract: Invention herewith described refers to the heat-absorbing generator of electricity with the Stirling engine (46) that absorbs the heat energy from the external environment through the external thermal collector (30), and concentrates it by means of the internal cooling device (31) on the hot side of Stirling engine (46). The internal cooling device (8) cools the cold side of Stirling engine (46) by absorbing the heat energy from the cold side in order to concentrate it on the hot side of Stirling engine (46). The internal cooling devices (8) and (31) are initially run by electricity from the external generator (53). Stirling engine (46) drives the electricity generator (48), which further takes over the supplying of the internal cooling devices (8) and (31) through the control assembly and the switching assembly (11). The heat energy absorbed from the external environment as well as from the cold side of Stirling engine (46) is four to nine times higher than the electricity needed for the operation of the internal cooling devices (8) and (31) which depends on the type of the internal cooling devices (8) and (31). The electricity from the generator (48) exceeds the internal consumption of the heat-absorbing electricity generator.
