I can't see how this would be efficient enough to charge a phone. Does anyone have a rough idea of what the end to end efficiency of this system would be?
Also if it's a beamed technology, does it then need N transmitters to charge N devices? How is the beam targeted?
Seems like a simple inductive charger would be much more practical.
