BACKGROUND OF THE INVENTION [0001] The present invention relates to a method for producing electricity. In some embodiments of the present invention, the method of producing electricity advantageously results also in the purification of water, including the desalination of sea water. The method of the present invention has particular and novel applications in the irrigation of land for cultivation, and a hybrid of an internal combustion engines. SUMMARY OF THE INVENTION [0002] The present invention relates to a method for converting heat energy into electrical energy. Initially, heat energy is obtained and transferred to a gas. The gas containing the heat energy is transferred to a compressor. The compressor is operated to compress the gas containing the heat energy, thereby concentrating the heat energy in a smaller area. The compressed gas containing the heat energy is brought into contact with a liquid in a heat transfer device, where the heat energy in the gas is transferred to the liquid, thereby converting the liquid to steam. The heat energy in the liquid is converted into mechanical energy. Finally, the mechanical energy is transferred to a generator where it is converted into electrical energy. In some embodiments of the present invention, steam from the heat transfer device is passed to a condenser where it is converted into water, preferably purified water. In some embodiments according to the present invention, the liquid is waste water, in some, sea water. [0003] As will be explained in greater detail below, the method of the present invention may be used to desalinate sea water which may then be used for drinking water or for the irrigation of land for cultivation. The electrical energy produced by the present invention may be used for various purposes, such as the propulsion of hybrid internal combustion engines. [0004] The device according to the present invention can be used to reduce heat in a closed or substantially closed environment in which heat build-up is a problem, by converting heat energy to an energy form which may be used and perhaps dissipated. The device may be used in conjunction with an internal combustion engine (either a hybrid engine or a traditional engine) in a vehicle that uses a liquid coolant. The heat energy can then be converted into electric energy to power the vehicle. Such conversion into electric energy allows the internal combustion engine to operate at its most optimal speed, and at the same time using the electrical energy to improve acceleration. DETAILED DESCRIPTION OF THE INVENTION [0005] The initial energy used to evaporate the liquid may be running or falling water, electrical, or fossil fuel, but is most desirably solar or ambient heat. It is particularly desirable that the water be preheated by any means, such as lava flows or solar energy collected by a large array of solar coils or panels which may or may not be black. [0006] The liquid is most desirably water, but may be other liquids such as crude oil (and other hydrocarbon fractions), alcohols and ammonia. Where the liquid is sea water, the device is desirably located near the sea, but may also be located in-land if a water tower or other collector is employed. In some embodiments of the invention, the first chamber containing the evaporator is located beneath ground level for heat stability and heat conservation. [0007] An important feature of the present invention is that it can be constructed with air conditioning components which are new, old or even discarded. [0008] Irrigation systems may be attached directly or indirectly to the water purifying device of the present invention. Such irrigation systems are not particularly limited and include those disclosed in U.S. Pat. Nos. 6,484,439, 6,619,565, 6,626,367, 6,695,231 and 6,834,662 which are incorporated herein by reference in their entirety. Most preferred among these systems are drip-systems. [0009] The steam engine component of the present invention is not particularly limited and includes those disclosed in U.S. Pat. No. 6,854,273 which is incorporated herein by reference in its entirety. Where operation must occur at low temperatures, a series of more than one steam engine component, working in tandem or in parallel, may be used.
