Perpetual Motion at last!

The Phone transmits radio energy which is converted back into DC power which the phone then uses to transmit radio energy.

Of course harvesting the radiated power blocks the ability of the phone to communicate, but still...

You could always just put it in.. like.. Airplane mode and call it a day.

Why didn't the judges ask about interference? How can the antenna determine what RF is ambient and what RF is being used in transmission? Seems pretty cool. 30% gain in battery would be game changing...
