Powercast promises wireless charging of consumer electronics at an 80-foot range
A second at-range wireless charging company has announced its Federal Communications Commission approval, and will be demonstrating its far-field technology, capable of charging multiple devices up to 80 feet away at the Consumer Electronics Show in January.

Powercast's implementation of far-field charging technology needs no charging mat or direct line of sight. Instead, the 3W transmitter uses the 915 MHz ISM band to send to a Powercast receiver chip in a device, which converts the transmission to DC to "directly power or recharge" an enabled device at up to 80 feet for devices with low power needs.
"Others might be talking RF power possibilities, but we have consistently delivered far-field wireless power solutions that work, safely and responsibly, under FCC and other global standards providing power up to 80 feet," said Powercast Chief Operating Officer Charles Greene. "Our robust technology has capabilities beyond today's permitted standards, so our product releases will evolve as regulations do."
Powercast expects up to 30 devices left in the zone on a countertop or desktop overnight can charge by morning, sharing the transmitter's three-watt (EIRP) power output. The company notes that charging rates will vary with distance, type of device, and power consumption.
The PowerSpot transmitter uses Direct Sequence Spread Spectrum (DSSS) modulation for power and Amplitude Shift Keying (ASK) modulation for data, and includes an integrated 6dBi directional antenna with a 70-degree beam pattern.
Devices cited as being good fits for the technology are devices like game controllers, smart watches, fitness bands, hearing aids, ear buds, or headphones charging best up to two feet away; with keyboards and mice up to six feet away. Accessories like TV remotes and smart cards charge well up to 10 feet away; with low-power devices like home automation environmental sensors getting sufficient charging power up to 80 feet away.
At January's Consumer Electronics Show, Powercast will be demonstrating a PoweSpot transmitter feeding into a Qi inductive wireless charging pad, like those used for the iPhone 8 family and the iPhone X. Additionally, it will show wirelessly powered game controllers, headphones, smart watches, earbuds, smart clothing, illuminated retail packaging, and reconfigurable retail price tags.
Powercast will begin production of its standalone PowerSpot charger shortly and is expecting a $100 retail on the transmitter at launch. Once PowerSpot reaches mass production, the company projects a $50 average selling price for the transmitter from major electronics stores with consumer electronics manufacturers offering it as an option on shipping devices.
The company claims that it is in discussions with several manufacturers, and has forged deals with a pair of "household names" for production of consumer electronics with the technology included.

We'll be talking about this from a scientific standpoint in 2018.
Wait - the sky is falling again and now they’ve electrified the space beneath and between it...?
What will we do? Oh yea... charge our phones and stuff.
Original thought may include some science from time to time but in general focusing on - just - thinking (sans junk science and The share sheet) would be appreciated. Not sharing will muffle the sudden and shrill of “Chicken littles” scream from the inside of every white mans elder soul.
Lastly - everybody dies.
Ah, the classic "appeal to ignorance" fallacy -- you don't have any evidence, but assert the truth of your statement nonetheless. Sorry, this fallacy doesn't hold water. To assert the truth of your claim (wireless is unhealthy!) you must provide the proof.

This sounds incredible. This would be fantastic for kids toys. Build the transmitter into a toy box or just in the room. If the kiddos put their toys away, everything works the next day. If not, all the batteries die.
We are even seeing Cars being charged wirelessly.
Yet, I can clearly remember seeing the effect on plants of magnetism back in the 1970's. Put the magnet one way round and the plant dies. Reverse the polarity and it grows stronger. This effect also applies to cancer cells.
I am not convinced of their safety.
All these extra RF Fields bouncing around our houses 24/7 can't be good for you in the long run.
Yes, the sun sends out a lot more but at least with the advent of night the level drops considerably. With these things, they are there all the time.
Who really knows about the long term effect of this sort of device?
