RF charger

Not sure if this violates laws of physics; please comment if you know a lot about this stuff.

first of all
How RFIDs Work:
1. an "RFID reader" emits some radiation
2. the radiation induces a tiny current in the antenna of an RFID
3. the antenna is connected to a tiny capacitor, which stores a tiny charge to power a chip that transmits an identifier

So...
perhaps it is possible to use this procedure for charging batteries:
1. have a charging pod connected to the wall outlet
2. the charging pod constantly emits radiation
3. a cell phone (for example) contains the antenna-capacitor circuit like an RFID, which in turn charges the battery from the current induced
---> so to summarize, you toss your cell phone and camera and whatever next to this charging pod and they get charged up

notes: 1. There are plenty of concepts and commercial products which are basically the same idea except they use magnetism to induce a current for charging. The only advantage of the RF version is that devices to be charged do not have to to be quite as close to the charging pod, and they do not have to be placed in a specific orientation (you just toss it in any way it falls)
2. I envision the charging pod as sort of a cloth box that contains the radiation transducer. So that way it's easy to just "toss" something in and know that it is at the correct distance to receive an adequate dose of radiation
3. I *think* the best thing to do would be radiation at very high frequency because higher frequency=higher power and shorter fall-off distance (so it doesn't cook you when you're standing across the room)
