...year round, on cloudy days as well as sunny ones, even at night. They are also cheap, consisting essentially of a sheltered, shallow body of salt water that acts as a solar collector, plus a heat-exchanging system and turbogenerator. The pond's operating principle is simple. When sunlight strikes a fresh-water pond, it heats the water and stirs up convection currents; cooler water sinks to the bottom while warmer water rises to the surface, where its heat quickly escapes into the atmosphere. In a solar pond, these currents are suppressed by dissolving salt near the bottom...
Amid the crumbling columns and pediments in the ancient city of Olympia, a shaft of sunlight glanced off a reflector one day last week and set fire to a slender torch. Next week, after a 5,000-mile flight from the Peloponnesian Peninsula to Athens to the U.S., and a 780-mile relay run from the Virginia Tidewater to the Adirondack Mountains of upstate New York, the Olympic flame will ignite a huge torch on a pedestal at the Lake Placid High School. With that, the 13th Olympic Winter Games "will be officially under way. In 1932, tiny Lake Placid...
Last week's pact calls for Atlantic Richfield to help finance joint ventures with ECD to develop alternative energy sources. Using Ovshinsky's theories, the two companies are looking for a much cheaper way to make photovoltaic cells that can convert sunlight directly into electricity...
...million futuristic long shot on Inventor Stanford Ovshinsky, 57, the president, founder and principal stockholder of Energy Conversion Devices of Troy, Mich. Arco, which initially gave ECD $3.3 million in funding last May, now believes the company's research hi new ways of converting sunlight into electricity has bright potential. Says Chambers: "The funding is our way of expressing confidence...
...will have to change tactics. As a first step, the U.S. should seek to create an international agency, perhaps under the auspices of the United Nations, to develop solar and other energy technologies appropriate for the special conditions of resource poor, less developed countries. In many of these nations, sunlight is the most abundant natural resource. While a bank of photo-electric power cells might be inappropriate for capital-poor developing countries, solar water heaters and buildings designed to take advantage of the sun could make a substantial contribution towards meeting these countries' energy needs. A multilateral agency could finance...
