A new type of solar energy collector concentrates the sun into a beam that could melt steel. Researchers say the device could revolutionize global energy production.

The prototype is a 12-foot-wide mirrored dish was made from a lightweight frame of thin, inexpensive aluminum tubing and strips of mirror. It concentrates sunlight by a factor of 1,000 to produce steam.

"This is actually the most efficient solar collector in existence," said Doug Wood, an inventor based in Washington state who patented key parts of the dish's design - the rights to which he has signed over to a team of students at MIT.
