...past, the cost of converting solar energy has been prohibitive, for solar batteries require the expensive slicing of silicon crystals...
...Chalmers and Thomas Surek, research fellow in metallurgy, are developing an inexpensive means for producing the crystals. The two scientists have been using a computer to simulate the silicon-ribbon growing process. Tyco is doing the laboratory work, including the actual growing of the ribbons...
...Sagan, it is scientifically possible for Mars to harbor "macro-organisms" the size of polar bears, who crunch rocks for water, sport silicon skins to protect themselves against deadly sunburn, and hibernate for thousands of years at a stretch. Sagan also contemplates astro-engineered civilizations so far advanced that their accomplishments would seem to us "indistinguishable from magic." He can easily imagine intergalactic, rapid-transit routes where "an object that plunges down a rotating black hole may re-emerge elsewhere and elsewhen-in another place and another time...
...able to produce more than a few drops of the miraculous water and skepticism began to grow. Now even Deryagin has washed his hands of polywater. In a recent scientific paper, reports Chemical & Engineering News, the Soviet researcher admits that it is nothing more than ordinary water contaminated by silicon. Where did the silicon come from? Apparently it was picked up in the hair-thin quartz tubes that he and other scientists used to produce the stuff from condensing water vapor. Comments Chemical & Engineering News...
...range of NASA'S big dish antenna in California's Mojave Desert that Mission Control learned the results. "We got the wing out and locked," reported Conrad. With a tug from the astronauts, the solar wing had swung out perpendicular to the ship and its accordion-like silicon panels were unfolding. However, hydraulic fluid in the panels' spring mechanism had stiffened in the extreme cold, and the panels only partially came out. Yet by week's end the warming rays had thawed the fluid. The panels extended fully, and the eight previously idle batteries began charging...
