  • Wind farm producing electricity at Altamont, California. Wind turbines. Wind Turbines. View of a wind farm with several wind turbines each with 3 spinning rotor blades. Wind power is used to drive a turbine for the generation of electricity. The electrical energy produced from a turbine is proportional to the cube of the wind speed. Thus, a 10-meter per second wind will produce 8 times more energy than a 5 meter per second wind. Wind turbines vary in size from large generators with a 1-3 megawatt capacity to small machines producing only a few kilowatts. (1985).

  • Solar energy: .UEC (United Energy Corporation of Hawaii) Solar Facility in Borrego Springs, California uses both photovoltaic  and solar thermal systems. What makes their operation unique is that they use 3 acre round ponds to float their solar arrays on. The ponds act as a frictionless water bearing so that it requires very little energy to have the whole surface of the pond rotate to face the sun as it moves east to west. A series of small motors tilt the individual rows of the arrays to track the sun vertically as well. They use hot water from one type of array to run a huge still, which produces alcohol from molasses. So far there are 18 ponds. Borrego Springs, California (1990).

  • Heliostats with central receiving tower reflected. Solar energy electrical generating power plant in the Mojave Desert near Barstow, California. Solar One consists of a circular arrangement of 1, 818 mirrors, each measuring 23x23 feet (7x7 meters). These mirrors focus the sunlight onto a huge central receiver, which sits atop a 300-foot (91 meter) tower. The mirrors are computer controlled to track the path of the sun. Water is pumped through the receiver and heated to a temperature of 960 degrees Fahrenheit. The resultant steam runs a turbine, producing 10 megawatts of power for eight hours a day. (1985).

  • Evan Menzel photographing trinitite at Site Trinity, ground zero, on the White Sands Missile Range in S. New Mexico. Site of the world's first atomic explosiion on August 6, 1945. The atomic bomb was developed by the Manhatten Project. The Manhattan Project refers to the effort during World War II by the United States, in collaboration with the United Kingdom, Canada, and other European physicists, to develop the first nuclear weapons. Formally designated as the Manhattan Engineering District (MED), it refers specifically to the period of the project from 1942-1946 under the control of the U.S. Army Corps of Engineers, under the administration of General Leslie R. Groves, with its scientific research directed by the American physicist J. Robert Oppenheimer. The project succeeded in developing and detonating three nuclear weapons in 1945: a test detonation on July 16 (the Trinity test) near Alamogordo, New Mexico; an enriched uranium bomb code-named "Little Boy" detonated on August 6 over Hiroshima, Japan; and a plutonium bomb code-named "Fat Man" on August 9 over Nagasaki, Japan.

  • Solar energy: Solar Plant 1. Warner Springs, California. Solar Plant 1 was the largest privately funded solar powered electrical generator in the world when it was built in 1984. Built by LaJet Energy Company of Abilene, Texas , SolarPlant 1 is a five megawatt distributed receiver facility. There is no central tower to soak up sunlight reflected from a broad field of glass mirrors. Instead, each of the 700 concentrators--consisting of 24 plastic mirrors kept in shape by a vacuum pump- reflects sunlight into its own receiver. Water is pumped through the receiver, which turns to steam to drive a turbine to produce electricity. (1985).

Water is pumped through the receiver and heated to a temperature of 960 degrees Fahrenheit. The resultant steam runs a turbine, producing 10 megawatts of power for eight hours a day. (1982).

  • Solar energy: Solar Plant 1. Warner Springs, California. Solar Plant 1 was the largest privately funded solar powered electrical generator in the world when it was built in 1984. Built by LaJet Energy Company of Abilene, Texas , SolarPlant 1 is a five megawatt distributed receiver facility. There is no central tower to soak up sunlight reflected from a broad field of glass mirrors. Instead, each of the 700 concentrators--consisting of 24 plastic mirrors kept in shape by a vacuum pump- reflects sunlight into its own receiver. Water is pumped through the receiver, which turns to steam to drive a turbine to produce electricity. (1985).

  • Solar energy: SEGS Solar Plant. Southern California Desert. Solar power. One of the three Luz International solar energy complexes in the Mojave Desert of California, USA. Together these sites, which cover 1000 acres, generate 275 megawatts of electricity, 90% of the world's total grid-connected solar energy production. This installation, located at Kramer Junction, has an array of 650,000 computer-controlled parabolic mirrors which track the sun across the sky, focusing it's light onto tubes containing a synthetic oil. The oil, which is heated to 391 degrees Centigrade, is used to boil water for steam turbine generators in one of five power plants. (1985).

  • Solar energy: Solar Power Tower. Computer Operated Reflectors operated by Sandia National Laboratories for the U.S. Department of Energy (DOE), the National Solar Thermal Test Facility (NSTTF) is the only test facility of this type in the United States. The primary goal of the NSTTF is to provide experimental engineering data for the design, construction, and operation of unique components and systems in proposed solar thermal electrical plants planned for large-scale power generation. Albuquerque, New Mexico. (1980).

  • Solar energy electrical generating power plant in the Mojave Desert near Barstow, California. Solar One consists of a circular arrangement of 1, 818 mirrors, each measuring 23x23 feet (7x7 meters). These mirrors focus the sunlight onto a huge central receiver, which sits atop a 300-foot (91 meter) tower. The mirrors are computer controlled to track the path of the sun. Water is pumped through the receiver and heated to a temperature of 960 degrees Fahrenheit. The resultant steam runs a turbine, producing 10 megawatts of power for eight hours a day. (1982).

  • Wind farm producing electricity at Tehachapi Pass, southern California. Wind Turbines. View of a wind farm with several wind turbines each with 3 spinning rotor blades. Wind power is used to drive a turbine for the generation of electricity. The electrical energy produced from a turbine is proportional to the cube of the wind speed. Thus, a 10-meter per second wind will produce 8 times more energy than a 5 meter per second wind. Wind turbines vary in size from large generators with a 1-3 megawatt capacity to small machines producing only a few kilowatts. (1983).
