Wireless electricity possible, says MIT

San Francisco (CA) - We have cut the phone cord, we have eliminated the need for a cable when connecting notebooks to the Internet and we use wireless headsets. But while audio and data transmissions through the air have become normal in recent years, we still need to carry around cables to recharge our portable devices. New research now indicates that even power may go wireless soon.

Forgetting to recharge that cellphone at night or forgetting the power cable for your notebook or iPod on a business trip are annoyances we have learned to live with. But it appears that researchers from the Department of Physics and Research Laboratory of Electronics at the Massachusetts Institute of Technology (MIT) have found a way to recharge mobile devices wirelessly.

growing organs from stem cells is possible, it doesn't mean much for the common man and probably won't for quite a while.

Very true. But at least now there is a group working on it. Thats more than can be said for a lot of the good ideas out there.

LOL Ever hear of the photo-electric effect? Einstein won the Nobel prize for it, and I am sure everyone hear has used an application of it (hint! solar power calculators).

Electricity is simply "electrons in motion." Very simple to have "wireless" electricity. However, transmitting omni-directional electrical pulses would be extremely inefficient. Think about it. Your cell phone provider doesn't know where you are, so they transmit their signal in all directions. Only a very small percent of their total sign gets to you. Transmitting electricity will prove to be far more expensive than can be managed.

Yes, but after all that, think about the profit the company will make
