RCA Announces WiFi Powered Battery

new battery chemistries don't pop up overnight.
They have to boost the voltage and thus losing energy in the process.

magical wireless recharging doesnt pop up overnight either, i say we dont rule anything out or make assumptions til we see it in use.
 
Yeah they go through some physics math in the linked article thread and the power gained is insignificant. Something like 20,000 hours to charge a cellphone battery, and that is close to the best case you could expect.
 
Wow... I have to admit this sounds pretty promising...

Leaving a device in a wifi area (aka my house) to charge would be amazing...
