It was in the news again recently. They changed the specs slightly so they could get a new patent on the same thing.

Free republic looked at it in this thread.

I think the low energy consumption of super bright LEDs make them the best option now though, especially if you were to put the rectifier and filter into the fixture and make 12VDC bulbs that would be interchangeable with automotive use LED bulbs. There is already a 12VDC rail on the USB buss and there a ton of small devices using 12VDC converters, so it seems to me a ubiquitous choice.

Thank you for the link:

Microwave lighting might work in offices and things that need lights in many areas at the same time but not very efficient in a house with very few lights on at one time.
