geothermal steam turbine
1Steam turbine — A rotor of a modern steam turbine, used in a power plant A steam turbine is a mechanical device that extracts thermal energy from pressurized steam, and converts it into rotary motion. Its modern manifestation was invented by Sir Charles Parsons… …
2Geothermal power — (from the Greek roots geo , meaning earth, and therme , meaning heat) is energy generated by heat stored in the earth, or the collection of absorbed heat derived from underground, in the atmosphere and oceans. Prince Piero Ginori Conti tested the …
3Steam engine — A steam engine is a heat engine that performs mechanical work using steam as its working fluid. [ [http://www.britannica.com/EBchecked/topic/564472/steam engine steam engine Britannica Online Encyclopedia ] ] Steam engines have a long history,… …
4Geothermal plant — A plant in which the prime mover is a steam turbine. The turbine is driven either by steam produced from hot water or by natural steam that derives its energy from heat found in rock. U.S. Dept. of Energy, Energy Information Administration s… …
5geothermal energy — Power obtained by using heat from the Earth s interior. Most geothermal resources are in regions of active volcanism. Hot springs, geysers, pools of boiling mud, and fumaroles are the most easily exploited sources. The ancient Romans used hot… …
6Geothermal gradient — The geothermal gradient is the rate of increase in temperature per unit depth in the Earth. It varies with location and is typically measured by determining the bottom open hole temperature after borehole drilling. To achieve accuracy the… …
7Geothermal — An electric generating station in which steam tapped from the earth drives a turbine generator, generating electricity …
8Tesla turbine — The Tesla turbine is a bladeless centrifugal flow turbine expander patented by Nikola Tesla in 1913. It is referred to as a bladeless turbine because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional …
9Hot dry rock geothermal energy — (HDR) is a type of geothermal power production that uses the very high temperatures (approx 200 Celsius) that can be found in rocks a few kilometers below ground. Electricity is generated by pumping high pressure water down a borehole (injection… …
10Enhanced geothermal systems — (EGS)Enhanced Geothermal Systems (EGS) enhance and/or create geothermal systems through hydraulic stimulation. When natural cracks and pores will not allow for economic flow rates, the permeability can be enhanced or stimulated by pumping cold… …
