Airnergy WiFi Harvesting Charger

RCA has created this hand held energy-harvesting battery .  This device is called Airnergy and is  used to charge by WiFi Signal. The price of this will be $40-$50 and they want it to be smaller than a smart phone.  The battery will charge depending on how close the battery is to the original signal. So far it is able to fully charge a Blackberry in about 90 minutes.  Do you think this will be a good product, me personally I think it will have a lot of issues as far as being able to keep a charge! But I could be wrong, I guess we will see how this product will turn out. Here are some sites to check it out and let me know what you think. http://ces.cnet.com/?categoryId=10406866&tag=rtcol
