SOLAR LASERS NOT JUST FOR JAMES BOND

  • An Uzbekistan researcher wants to focus the sun's energy into a laser to use as renewable energy.
  • The scheme would involve using 3-foot-wide parabolic mirrors.

Harnessing the sun's rays to produce a beam of pure energy has long been the goal of inventors from the ancient Greek engineer Archimedes (focused mirrors to destroy invading ships) to James Bond villains (space-based lasers of "Diamonds are Forever" and "Die Another Day").

But new research may realize the dream for a more down-to-Earth use: renewable energy.

A researcher in Uzbekistan has proposed a plan using small parabolic mirrors about 3 feet in diameter, combined with new two-layer ceramic disks to produce laser light.

"It is possible to make solar-powered lasers with the efficiency of 30 to 40 percent," said Shermakhamat Payziyev, a researcher at the Scientific and Production Association "Akadempribor" in Tashkent.
