On the Air- Wireless Electrical Connectivity

With our electronic world now becoming a mess of cords, power strips and adapters to plug in our new world gadgets think of a world where the cord becomes obsolete.

We can thank that wonderful think tank of MIT with what maybe the next biggest revolution in electrical connectivity. This is where Physics meet practical applications.

Nikola Tesla theorized something like this about 120 years ago with “resonant inductive coupling”, also known as "electro-dynamic induction".

Now to the future welcome to WiTricity Corp, a company founded in 2007 that is taken this electromagnetic theory from the lab bench to laptop.

Using an oscillating magnetic field there are able to take electricity convert it to a electromagnetic field and use of magnetic coupling to take that energy and convert it back to electricity at the receiver that could be built into our electronic devices.

MIT Professor Marin Soljačić (pronounced Soul-ya-cheech) came upon this idea after hearing his cell phone beeping because of low battery and wonder why could not use all this power around the home. Marin quotes  “There is electricity wired all through this house, all through my office—everywhere. This phone should take care of its own charging!”. An idea is born.

Think of it as wireless internet for electricity. I for one can not wait to see this become common place.

Here is a report from CNN on this.

Here is the 2009 TEDtalk link-  http://www.ted.com/talks/eric_giler_demos_wireless_electricity
