Abstract
A method and system to use compressed fluids to generate electrical energy or an equivalent useful form of energy. A first embodiment uses pressurized air that can be stored to selectively and directly generate energy as required. A second embodiment uses a pressurized working fluid that can be stored to selectively and directly generate energy as required. A third embodiment uses at least one compressible floor module to compress at least one working fluid that can be stored to selectively and directly generate energy as required. The working fluid in various embodiments of the invention can be air, steam, oxygen, hydrogen, nitrogen, commercially available Freons, carbon dioxide, methane, ethane, propane, butane, various types of natural gas, ammonia, an equivalent type of gas, or an appropriate liquid.
