Wireless light bulb

johnwa:
There has been a considerable amount of discussion surrounding wireless light bulbs of late, with a number of products being marketed for use in “smart home” installations. However, all the units I have examined have failed to live up to expectations, in a fairly fundamental way.

My current project has been the development of a true wireless light bulb. As can be seen from the photo of the prototype unit, it is capable is functioning without any wires whatsoever. I  should have a full circuit description put together in the next few days, but in the meantime, you can have a look at the demonstration video at http://loopgain.net/wirelesslightbulb/wirelesslightbulb.mp4

My entire lab is wireless, I'm completely disconnected from the grid except for the ground. It's true that when I turn on the old HP spectrum analyzer, the frequency has a hard time keeping up, it goes down to about 57Hz from 60Hz, but it's not too bad. The entire lab when everything is turned on, takes less than 400W however.
I tried the same thing with the fridge but it blows the fuse, I'm not there yet (inrush current). The lab is ok.
I can't wait to see your idea, then I'll post mine.

Looks like another April fools gag.
Buriedcode:
Don't you open that trap door.  You're a fool if you dare.
Nusa:
Just another wireless resistor application. Nothing to see here.
