The electricity generation is tedious process. There are various sources of electricity generation including coal, water turbine, wind mill but all are equally polluting the ecology. The cost of building these technologies is also very expensive. One of the best technologies disclaimed above is water turbine, because it generates electrical energy by utilizing mechanical energy. For small community electricity generation this is the best technology where the availability of water source is adequate. By using hydraulic air compressor generator, we can construct it with low cost nano construction material, thus electricity generation and refrigeration is made simple. This is green energy device hence it is a non-polluting technology.
