Here is the description from their site.
Just plug the Wireless Extension Cord (WEC) base unit into a standard wall outlet, and plug whatever you need into the satellite unit. The WEC uses microwaves in the 7.2GHz range, so it won't interfere with wireless networks, Bluetooth components, etc. Now, all you need to do is adjust the antennae on the two units so they are aimed at each other. Turn everything on and you have the power! The distance the WEC units can broadcast differs from situation to situation (due to interference of such things as walls, power lines, and microwave ovens), but we've beamed power over 300 feet! The future is wireless - and the WEC's are your ticket to the future.
Warning: Even though these microwaves are about as harmful as the leakage from an ordinary microwave oven (not much), do not put computers, televisions, other sensitive electrical equipment, food, liquids, paper, glass, flammable substances, magnets, or living things in between the base and satellite units. Just in case.
I thought it was insane.
LOL thinkgeek's April Fools jokes are up early.
p.s. -- your usersound starts out like some electrical gadget going haywire.
Oh My God. Great, now I'm afraid of my microwave. I'm gonna starve.
'or living things'???? so if you walk between them, what, you get a jolt to the heart?? Haha.
