Pulling The Plug

Whenever we set up for a training session, the number of power strips daisy chained across the room for the laptops would upset the fire marshall.

The computer labs in some of our schools would send him into cardiac arrest.

We have wireless internet access. Wouldn’t it be great to have wireless power?

Coming right up.

The tangle of cables and plugs needed to recharge today’s electronic gadgets could soon be a thing of the past.

US researchers have outlined a relatively simple system that could deliver power to devices such as laptop computers or MP3 players without wires.

Well, maybe not quite that soon.

The MIT researchers behind the concept haven’t actually built a wireless power system. However, “computer models and mathematics suggest it will work”.

I don’t understand the science behind all this but it’s still a cool idea. However, I do have one question.

What happens when human flesh gets between the electrical source and the device being powered?

I guess that’s just one of the “number of other aspects that need to be addressed to ensure efficient conversion of power to a form useful to input to devices”.

Stay tuned. And plugged in.

wireless, power, mit

    This is awesome!! Every time I do a workshop and I have my computer, the projector, the wireless response system, the huge brick for my old but wonderful Apple speakers, I remark to the group that I could really really use wireless electricity. Actually, I’d be happy to plug in an ethernet cable and forego wireless Interent!

    Hasn’t anybody in this brave new world of ipods and wirelesss ever heard of Nicholas Tesla????? broadcasting power without wires was an idea that he worked on (and in many ways perfected) nearly 100 years ago. His Wydencliff generator project was the first attempt at a large scale Power broadcaster that was not meant to send power across a room without wires (which he did do) but was meant to send power around the world wirelessly.
