PowerBeam steps closer to launch of wireless electricity
Transferring electricity through the air to power an electronic gadget seems impossible. Nikola Tesla, the radio pioneer, tried unsuccessfully to do it in the early 1900s. Technical hurdles have plagued the attempts to do the same thing ever since.
But PowerBeam, a small Sunnyvale, Calif.-based company that I first came across in April, 2007, says it is making progress on a technology that can transfer electricity — or more accurately generate electricity — across a room…. Continue Reading
Intel brings wireless power closer to the mainstream, Nikola Tesla would be proud
Intel is mainly known for its microprocessors, but it’s another technology that was unveiled at this week’s Intel Developer Forum (IDF) that has a lot of people talking: Wireless power.
To some, the idea may sound like pure science fiction, but it is very real. Various groups of scientists around the world have been working on it for years, but the problem has mainly been the efficiency, or rather the inefficiency with which power is transfered… Continue Reading
Powerbeam, the wireless electricity start-up
Powerbeam, a new Silicon Valley start-up, is working on a revolutionary idea: Using a laser to beam light, the energy of which would be used to power your laptop or other device without having to plug it in.
PowerBeam says its powerful laser can transmit more electrical power than other methods, and it comes with a safety feature. Dean Takahashi of the Merc has seen the product demonstrated, and he’s duly enthusiastic.
As Dean describes it, here’s… Continue Reading
