Nikola Tesla On Hot Dry Rock Geothermal Electrical Power Generation |
Site Map |
"It is a well-known fact that the interior portions of the globe are very hot, the temperature rising, as observations show, with the approach to the center at the rate of approximately 1� C. for every hundred feet of depth." � The Problem of Increasing Human Energy, 1901 "All that is necessary to open up unlimited resources of power throughout the world is to find some economic and speedy way of sinking deep shafts." � Our Future Motive Power, 1931 Hot
Dry Rock Geothermal Electrical Power Generation and Deep Shaft Techniques |

The arrangement of one of the great terrestrial-heat power plants of the future. Water is circulated to the bottom of the shaft, returning as steam to drive the turbine, and then returned to liquid form in the condenser, in an unending cycle. . . . The internal heat of the earth is great and practically inexhaustible. . . .
Nikola Tesla's development of a system
for the generation, distribution and utilization of electricity caused
him to invest considerable thought into potential sources of mechanical
energy to support the process. In 1931 he wrote an article for Everyday Science and Mechanics
entitled "Our Future Motive Power" which analyzed some
alternatives to the combustion of fossil fuels for obtaining electrical
power. A closely related piece also appeared in the New York
Times. The following observations on hot dry rock geothermal energy
technology for AC power generation are derived from these two pieces. |
