Goodbye wires... MIT experimentally demonstrates wireless power transfer

Posted June 10, 2007 7:35 PM

From PhysOrg.com:

Imagine a future in which wireless power transfer is feasible: cell phones, household robots, mp3 players, laptop computers and other portable electronics capable of charging themselves without ever being plugged in, freeing us from that final, ubiquitous power wire. Some of these devices might not even need their bulky batteries to operate. A team from MIT's Department of Physics, Department of Electrical Engineering and Computer Science, and Institute for Soldier Nanotechnologies (ISN) has experimentally demonstrated an important step toward accomplishing this vision of the future. The team members are Andre Kurs, Aristeidis Karalis, Robert Moffatt, Prof. Peter Fisher, and Prof. John Joannopoulos (Francis Wright Davis Chair and director of ISN), led by Prof. Marin Soljacic. Realizing their recent theoretical prediction, they were able to light a 60W light bulb from a power source seven feet (more than two meters) away; there was no physical connection between the source and the appliance. The MIT team refers to its concept as "WiTricity" (as in wireless electricity).

1) Cell Phones, IPod, etc etc are small

2) Small volume will have small resonator

3) Small resonators means High frequencies

4) World is worrying about ill effects of such RF radiation even when its power is in milliwatt range (cell phones)

5) What would happen if you send High power In such frequencies?

Is there any body thinking like this?

This Article is telling that there are possibilities of having rooms without wires, so that when you enter that room your laptop will be charged automatically.

I think we may need to wear a Helmet kind of thing to protect our brain from that radiation. Other wise brain will boil like an egg in oven

But this is a very good Idea and I appreciate such inventions if they are not harmful to the human kind.

very good, felows, but... you are 70 years late than Nicola Tesla (and the files FBI took from his home after his death). Keep it up but read Nicola's works first and take care to... never break the existing cycle too fast.

In my Navy days, we would undo a transmitter waveguide, so that RF was being sent across the Radio room, then give a young Erk a handful of neon bulbs or a fluorescent tube, to carry over to the other side - thru the RF of course. The bulbs and or tube would fully light up, shocking the poor nitwit!!!

But it was not practical as the losses were so high, so I tend to agree that this is a garbage CR4 entry......as mentioned many times, Tesla did it, but the losses and the smog are horrendous!!!
