An Underground Radio to Save Lives

Posted by ryuzaki0 on Saturday May 6, 2006 @08:33AM from the technology-with-depth dept.

Roland Piquepaille writes "The Duluth News Tribune wrote last week about a communication device which could be a lifesaver for miners. This invention is the brainchild of David Reagor, a physicist at Los Alamos National Laboratory (LANL). His prototype radio works at depths of 500 feet and is based on very low frequency electromagnetic radiation and digital signal processors. A commercial version is in the works and could be used not only by workers trapped in a mine, but also by firefighters and other emergency workers to communicate with people in collapsed buildings or subways."

Lifesaver for commuters, too by ozbird · 2006-05-06 10:30 · Score: 4, Interesting

As loss of radio contact was one of the factors the resulted in Jean Charles de Menezes being shot dead by police, radios that work in the Underground ("tube") as well as underground would be a good thing.
