Wireless Power: Charging Devices – Without the Wires!


Is your mobile device out of power already? No problem, just raise the antennae and let it tap into the vast power of the many radio frequency (RF) signals that are already being transmitted. That would be the ideal, and it’s close to what can happen now. Introducing Powercast, a startup company that is partnered with over 100 companies to provide wireless power.

That’s right! Wireless power! Using an enhancement to radio frequencies that are optimized for power transmission, Powercast’s technology allows for charging over the air up to 3 feet away from the RF transmitter! This special RF receiver is only the size of a dime and costs around $5 to manufacture. Opportunity knocks and certainly the industry heeds the call! Expect wireless keyboards, mice, and game controllers with this technology to hit the shelves next year. Thanks SolSie for the electrifying info!

This is pretty cool tech. I think it’s the electrostatic version of the separated pri-sec transformer.

Alright, so I actually read the article this time… they’re using radio waves. I did read another idea for using electrostatic energy, and many current consumer products use the split pri/sec transformer already (like my electric toothbrush and razor)
