Its not magic its science! Wireless power

post #1 of 22
Thread Starter 
I had been brainstorming on how to do this for some time and they thoguht of the one thing i didnt...


Quote:
Typically, systems that use electromagnetic radiation, such as radio antennas, are not suitable for the efficient transfer of energy because they scatter energy in all directions, wasting large amounts of it into free space. To overcome this problem, the team investigated a special class of "non-radiative" objects with so-called "long-lived resonances". When energy is applied to these objects it remains bound to them, rather than escaping to space. "Tails" of energy, which can be many metres long, flicker over the surface.

"If you bring another resonant object with the same frequency close enough to these tails then it turns out that the energy can tunnel from one object to another," said Professor Soljacic. Hence, a simple copper antenna designed to have long-lived resonance could transfer energy to a laptop with its own antenna resonating at the same frequency. The computer would be truly wireless. Any energy not diverted into a gadget or appliance is simply reabsorbed.

The system could transfer power over "three to five" meters

long live wireless power!!!

we'll any decent company will probably have the copper concealed. The only problem i see with this is walking into Starbucks with someone wirelessly charging their laptop from the outlet an you come in and steal their power.

or better yet i cant wait till this tech is more powerful and can range as far as wifi can. Imagine being in the middle of a street and having your laptop charged while you steal someone elses' wifi!

haha

Imagine hooking up a wireless power connection from your neighbors house to yours. Picture the Husband yelling at the wife," why's the power bill so high".

Hmmm, interesting, brings up something. Current processors use electricity through wires, like what we use to charge batteries, what about doing this same thing to make processors, like in a vacuum to have less interference? Too complex as of now though .

Neat none the less to be able to charge a battery wireless.

I just hope this doesn't turn out to cause cancer or something, that would kill this tech before its ever off the ground Seriously though that's really amazing, imagine having an electric car and being able to charge it simply by parking it in the garage, or better yet combine it with nano-tube batteries and be able to drive into a gas station, charge your car in 30 seconds and drive off without ever having to set foot out of the car to connect anything.

I kind of want to stay away from this new "wireless power" phase we are going through; I really don't want cancer
