Method for generating electrical energy from compressed air energy and geothermal energy for e.g. passenger car, involves supplying mechanical energy and compressed air energy to earth surface for conversion into electrical energy

摘要

The method involves boring earth holes with diameter of 100 mm and with depth around 3 to 14 km by supplying water into a register pipe. Main holes with diameter of 600 mm and with depth around 1 to 1.4 km are bored in an underground working area. Mechanical energy and compressed air energy are supplied to earth surface and stored for conversion into electrical energy by an air-motor-electric generator-set-coupling. Independent claims are also included for the following: (1) a device for high pressure air storage (2) a device for reducing air pressure.
