This is what I call an great invention.
This little box can harvests an enerfy from WiFi signals out there in the air and then converts it into electricity. Airnergy is able to collect this electricity with a high efficiency.
Apparently, they were able to charge a BlackBerry from 30% to full in about 90 minutes, using nothing but ambient WiFi signals as a power source.
What’s inside the box? The Airnergy has a battery inside it, so you can just carry it around and as long as you’re near some WiFi, it charges itself. The big advantage over for example a solar chargers, even the most efficient, it is, that it works at night and you can keep it in your pocket.
Well, you need to have a Wifi signal close, but in the city centers there is not to worry about that. At home you for sure are having your little home network with wireless router, so just leave anywhere in your house overnight and it would be pretty close to full in the morning.
The incredible is that RCA says that the USB charger will be available this summer for $40, and a battery with the WiFi harvesting technology will be available soon after.
This could be a revolution for how we charge the gadgets we all carrying around.
