FOR IMMEDIATE RELEASE
Three dish-shaped solar thermal energy concentra-ì
ì
tors for generating electrical power will be designed and ì
ì
built by General Electric Space Division of Valley Forge, ì
ì
Pennsylvania, and installed at the NASA Jet Propulsion ì
ì
Laboratory's Solar Thermal Test Site at Edwards, California.
The 16-month contract was awarded to GE by the Jet ì
ì
Propulsion Laboratory of Pasadena, California, for the U.S. ì
ì
Department of Energy (DOE). It is the second of a two-phase ì
ì
DOE program aimed at development of a low-cost, point-ì
ì
focusing solar concentrator.
The three prototype concentrators will be 12 meters ì
ì
(40 feet) in diameter and will include the mechanism that ì
ì
allows the concentrator to track the sun.
A point-focusing solar concentrator directs mirror- ì
ì
reflected solar radiation to a centrally located heat ì
ì
absorber connected to a heat-driven engine and generator. ì
ì
Using this concept, solar energy can provide electrical power ì
ì
to small communities and rural areas.
Heat absorbers and heat engine generators for the ì
ì
installation are being developed under separate contracts.
In addition to design, fabrication, and installa-ì
ì
tion of the concentrators, GE will perform acceptance testing ì
ì
to demonstrate performance. Working with JPL, they will also ì
assess the implications of mass production and cost potential ì
ì
of the system.
The goal of the program is to obtain the greatest ì
ì
thermal performance at the least cost. It is managed by JPL ì
ì
for the DOE's Solar Thermal Distributed Receiver Program. ì
ì
The work is being done for DOE under an interagency agreement ì
ì
with the National Aeronautics and Space Administration.
