As I prepare to feed my wireless keyboard and mouse more AA and AAA batteries, I stop to wonder, what technical / economic hurdles are preventing the wireless device manufacturers from developing a way to power these devices wirelessly
I would imagine that by turning the reciever that plugs into the usb port a .5W transmitter you could put a reciever into the keyboard so that when you are not typing, it's either charging, or even better, have no active power on the device at all, but act sorta like the way an ID badge does,
The badge reader sends out little pulses of RF that an antenna in the badge picks up, translates that into current, runs that current through a chip whip then pulses out a RF signal of it's own with a code embedded in it
I'm pretty sure that with a little effort, the propeller heads at logitech or microsoft could make this work. This wouldn't work that well over 6 or more feet, but for a majority of the users that I know if, we are talking about a distance between the xmitter and the keyboard of only 24" or less
shoot, I bet if you built the reciever right, you could build it to allow you to track the location of something like a stylus on your desktop, sort of like a digitizer pad, but without the actual tablet...
if anyone makes this works and makes bucks on it, remember me and send me some kit
