do you think it would be possible to have a "contactless charger" where by you just drop your cell, pda, mp3, camera, bluetooth headset, laptop, etc next to a charging widget, without actually inserting a cable or physically conecting contacts?
I was thinking maybe you could just have this charger widget that sends out very low power very high frequency (100GHz or something) radio waves. and a device that is designed to charge by it would have a little antenna in it connected to a capacitor that gets charged by the waves and creates a constant DC current.
