Abstract
A geothermal well power-generation system is monitored by sensors permanently associated with the operating power generation system. These sensors detect changes in well water temperature, water pressure below and above the pump, and pump rotating speed. The data obtained is transmitted to a receiver at the earth's surface via sections of the system's plumbing which are utilized as an electromagnetic transmission line.
