They've needed something like this for a long time!

The problem with all my electronic gadgets is getting power to them all. I've thought about wireless speakers but you still have to get power to them where ever they are. They've finally figured out a way to use microwaves (7.2GHz range) to “beam” power from an outlet to another location in the same room (line of sight). These wireless extension cords should have a range of 100 feet (although ThinkGeek says they've tested them up to 300 feet) which is way more than enough. This will totally change the way I've got my living room configured! (And they're only $34.95!)
