"It remains to be seen exactly what the specifications and consumer reception for Ossia and uBeam's technology will be. Nonetheless, the need for wireless power is real across a variety of applications. From simple consumer cell phones to electric vehicles, wireless power would fill a real need. If power could be transmitted long distances wirelessly, it would completely change "range anxiety" which has held back the EV market."

Unfortunately the laws of physics says this is highly inefficient.

The efficiency is of minor importance when doing things like charge a
cell phone with takes milliwatts, but becomes totally impractical at
the megawatt level it would take to power even a small vehicle.
