Abstract
A hydroelectric and geothermal system includes a fluid communication channel that includes a first portion that extends from the earth's surface toward a subterranean hot area, a second portion connected to the first portion and in thermal communication with the subterranean hot area, and a third portion connected to the second portion and that extends to the earth's surface. A first turbine generator is configured to convert kinetic energy of a fluid flowing substantially under the influence of gravity in the first portion of the fluid communication channel into electrical energy. A second turbine generator is configured to convert kinetic energy of a vapor flowing within or out from the third portion of the fluid communication channel into electrical energy. The system also includes a valve arrangement configured for manipulation to hold the fluid in the second portion of the fluid communication channel in thermal communication with the subterranean hot area to produce the vapor.
