Yup!

Charging a phone while walking around a room is a pipe dream. Enthusiasts and investors should look at the technology’s realistic usability and limitations before buying into the hype.

The only ways to overcome the dissipation of power would be to increase the strength or focus the direction of the transmitted field. On the one hand, increasing power levels could present severe detrimental human effects and on the other, focusing the direction of the signal would limit the freedom of movement while concentrating the energy to unsafe levels in the focused areas. Due to these safety concerns, the FCC has determined what it considers a safe amount of long term exposure and limited the amount of power that can be transmitted. As long as biological humans are the end-users of the technology, this physical limitation will make this technology impractical.

Today’s devices require a substantial amount of power to charge. Typical devices’ ideal charging rates are measured in watts, not milliwatts (1,000 of a watt). For instance, Apple and Samsung phones charge at 5 to 12 watts, thus a milliwatt signal cannot maintain a charge on today’s phones or other electronic devices. Mathematically, for Energous to charge a phone, it would need to be turned off, stationary and positioned very close to the transmitter before any charging would occur. Other than an interesting concept to discuss around the water cooler, it’s just not practical.

WATT is headed for zero, like many other "failed concept" companies...

The sooner one realizes that, the more of one's investment that can be saved!
