Power towers or solar furnaces, which use huge expensive banks of computer-controlled mirrors to track the sun and focus its rays on large electricity-producing steam boilers...
...immediate problems, so many large companies are moving into solar power with an eye to the future that Congress is already worried about antitrust problems. Most of the firms are looking for better and less costly ways of collecting the sun's energy and storing it for rainy days or nighttime use, with one ultimate aim of exporting their technology to less developed countries. General Electric recently developed a tank that uses common salt to store for long periods heat collected by solar panels. Along with Owens-Illinois, G.E. is also working on advanced vacuum-tube rooftop solar collectors...
...panels are sprouting as the ultimate in status symbols. The units are often unattractive (one California city now insists that they somehow be screened), and can cost from $7,000 to $12,000 to heat an eight-room house. Solar is also being used by industry. Anheuser-Busch employs sun heat for some beer pasteurization, Campbell's Soup to heat water to wash its cans, Tropicana to steam-process its orange juice. Solar energy provides heat or hot water or both in a visitors' center at Mount Rushmore, S. Dak., Disney World's office block in Orlando...
...HELIOS, as at Harvard, last week witnessed the most spectacular demonstration of the decade. After five-and-a-half years of inactivity, a flare scorched the solar surface, shorting out the South Atlantic and juicing up the aurora borealis as far south as Cambridge. Fortunately, most of the sun's radiant energy reaches the earth in a form more suitable for earthling endeavor...
...campaign to harness that solar energy will reach its first milestone on Sun Day, a national celebration of solar resources scheduled this week in place of Wednesday. Locally, films, exhibits, demonstrations and picnics at and around MIT and the Boston Museum of Science will present the myriad possibilities for solar energy development. There will also be a speech at Harvard by David Jhirad of the Union of Concerned Scientists, who will discuss the potential of alternative energy sources...
