Background: The United States government, in partnership with industry, is conducting major experiments into how energy can be harnessed on so-called "solar farms". It's an effort to find the best ways to tap the inexhaustible energy available from sunshine.
SYNOPSIS: This is the research version of a "solar farm"...a predecessor perhaps to possible fields of collectors that may one day be used to harvest solar energy. This experimental area is located on the edge of the Mojave Desert in California, where temperatures are high and the sun shines consistently.
Very simply, the dish-shaped systems are covered with mirrors which reflect and focus the sun's rays to a point where the intense heat is converted to electricity. The huge mechanisms, which look very similar to radar tracking devices, across follow the sun as it moves the sky. In theory, rows of these concentrators, as they are called, would make up a solar farm, providing enough electric power for a small city or a number of factories. The goal is to produce electricity at a cost low enough to compete with oil, coal and gas. It's estimated that 400 collectors on 40 acres of land would be needed to service a moderate sized industrial plant or farm.
Nasa's jet propulsion laboratory in Pasadena is involved in solar cell research. Solar cells generate electricity directly from the sun's light and have been used to provide power for spacecraft. Engineers here monitor the electrical characteristics of dozens of different types of solar cell modules. Data is also being gathered at 12 other sites from Alaska to the Canal Zone. The cells are thereby subjected to extreme as well as moderate conditions...from minus 40 degrees (Fahrenheit) cold to 190 degrees hot.
