Hi,

Im just wondering if anyone as heard of 'Power Over Wireless' the transfer of electricity to things such as cell phones without a cable. Apparently also a cell phone company has taken out a patent for a device that switches the cell phone on when it detects a wireless signal and powers itself. So you dont waste battery power but when you find the wireless power it charges itself - pretty cool.

Yup, MIT and a lot of others have been working on it for a while. Here's a good article I found about it.

This is fascinating stuff. I've seen charging pads (where you lay the device(s) onto the pad) and there has been a lot of talk about power over wireless in some circles.

It would solve a lot of problems, that's for sure.

Indeed! Bluetooth has solved the problem (in theory) of getting access to phonebook etc. and inductive loops can resolve the issue of using the external antenna without a direct connection; all we need now is wireless power and there's suddenly no need for snap-in adaptors!

Come on BMW, how about putting this in our cars?

It's coming. I would wager we see it first from Ford in cars with SYNC however.
