Last year, on TV (may be CNN), it was reported that microwave transmitters were going to be used to generate light in long tubes for corporates’ corridors and like. It was reported as an energy saving technology, but safety was not discussed.
Does any one know of a mass production of such a thing?

 

Check these websites -- I found them using Google.
