Wireless power transfer

11 10 2008

Today, during wireless networking lecture my professor was talking about wireless USB drives. They are based on UWB protocols. I can understand wireless data transfer, but I still need wire to charge my USB device so that it can transmit data to my computer.

It is a coincidence that immediately after the lecture I stumbled upon one article from Technology Review that talks about wireless energy transfer. Here is the link to the article:

Emerging Technology: Wireless Power

A professor in MIT has come up with the method of generating wireless power using magnetic resonance. Also, to my surprise, I came to know that there are already some wireless adapters and pads by which you can charge your cellphone, mp3 player etc.

Hmm.. thats pretty interesting…. so do you think finally wireless world is here???

Naah, I don’t think so. All current technologies work best over small range. Also, it is bit risky to be exposed to wireless energy radiations all the time. With so much radiation around, I guess scientists will come up with special type of clothings that will reflect all harmful radiations. so cloth specifications will read ‘100% microwave proof’ or something like that. 🙂

Just kidding…
