Sounds good, but there are significant roadblocks ahead. For one thing, your devices would need to be built with base receivers or otherwise retrofitted to work with a magnetic resonance power source. That can be done — and done cheaply, Lidow said — but it's going to require time, effort, and partnerships. In a recent demo video, Lidow shows a series of devices fitted with EPC antennae, including an LED desk lamp, a computer monitor, and an Amazon Echo, demonstrating the ease with which currently available devices could be retrofitted.
Another problem with magnetic resonance systems is, when you run several devices in close proximity, the resonant fields tend to interfere with one another. Lidow said his company has resolved that problem. But he wouldn’t offer details, citing concerns about tipping off potential competitors.
“When you change the electrical load, the resonance changes,” he said. “Your monitor might need 50 watts, your computer is 30 watts, the cell phone is 15 watts. That's not an issue for us. It's power on demand.”

The EPC system can be deployed vertically as well as horizontally — another plus for the technology. The transmitter surface is thin and easily rolled up like wallpaper, which means you might one day install a patch of magnetic resonance material on your wall, hang up your flat-screen TV, and finally get rid of that dangling power cord. And because there's no technical limit to the amount of power magnetic resonance can provide, you could even power large appliances like refrigerators and washing machines.
When can we expect to arrive in this promised land of wireless electricity and finally banish ourselves of power cords? Lidow said his company only deals with the core technology, so much of that is outside of his control. But he's optimistic.
“You know, I'm not in the table building business,” He said. “We make gallium nitride circuits. But we're carefully choosing partners and hopefully within a year or so we'll start seeing furniture on the market with this system already built in.”
Lidow said, as a guy with too many devices himself, he doesn't like power cords either.
“For the last several years we've been arguing about standards and formats and trying to solve what I think are fairly rudimentary technical problems,” he said. “But now we've got the solutions, and it's time to roll this damn thing out.”
