Intel cuts electric cords with wireless power system

Intel on Thursday showed off a wireless electric power system that analysts say could revolutionize modern life by freeing devices from transformers and wall outlets.

Intel chief technology officer Justin Rattner demonstrated a Wireless Energy Resonant Link as he spoke at the California firm's annual developers forum in San Francisco.

Electricity was sent wirelessly to a lamp on stage, lighting a 60 watt bulb that uses more power than a typical laptop computer.

Most importantly, the electricity was transmitted without zapping anything or anyone that got between the sending and receiving units.

"The trick with wireless power is not can you do it; it's can you do it safely and efficiently," Intel researcher Josh Smith said in an online video explaining the breakthrough.

"It turns out the human body is not affected by magnetic fields; it is affected by elective fields. So what we are doing is transmitting energy using the magnetic field not the electric field."

Examples of potential applications include airports, offices or other buildings that could be rigged to supply power to laptops, mobile telephones or other devices toted into them.

The technology could also be built into plugged in computer components, such as monitors, to enable them to broadcast power to devices left on desks or carried into rooms, according to Smith.

"Initially it eliminates chargers and eventually it eliminates batteries all together," analyst Rob Enderle of Enderle Group said of Intel's wireless power system.

"That is potentially a world changing event. This is the closest we've had to something being commercially available in this class."

Previous wireless power systems consisted basically of firing lightning bolts from sending to receiving units.

Smith says Intel's wireless power system is still in an early stage of development and much research remains before it can be brought to market.

Rattner spoke of technological transformations he expects by the year 2050.

"You'd like to cut the last cord," Smith said.

"It's great that we have wireless email and wireless internet and stuff like that but at the end of the day it would be nice to have wireless recharge as well."

I want one, you have no idea the amount of times when I am outside I had to frantically search for a power point when my battery is low.

I wonder what effect this would have on an electrical device that was caught in the cross fire that didn't support wireless electricity. Everyone knows what happens if you put a magnet near a CRT screen. Surely pumping a magnetic field near it will cause exactly the same distortions.

Also, for the record, the effects of magnetic fields on people isn't something that is truly understood. Tests have shown that magnetic fields can affect eyesight and your heart. Another theory is that magnetism can affect our central nervous system. Think of your nerves as a bunch of wires - in the right magnetic field, a current in these wires can be induced.

Nobody really knows if there are negative (or positive) affects of any of that, but there is evidence of a connection between magnetism and the human body.

Did you actually read the post? I transfers energy using MAGNETIC fields NOT electric... human bodies are not affected by Magnetic fields..

Electric and Magnetic fields are two sides of the same coin. To be honest, it's possibly just the way we developed our notation and understanding of the phenomenon that led us to separate the two like we do.

For instance, if I'm walking next to a stationary magnetic field, I will see a small electric field developing. They're both electromagnetic fields being carried by photons.

Furthermore, there's really not too much evidence that the human body is affected by non-ionizing frequencies of electric fields. Ever stood anywhere where there's this pesky 'light' thing? You're being surrounded by a massive electric field! The only thing that we know happens is that you might heat up a little bit. For instance, infrared and below can penetrate further into your body than visible light, but they just cause a little bit of warming.

In any case, this is just inductive coupling. This is how electric toothbrushes are charged, and we've been using it for decades. Tesla did a ton of experiments with it, and it's also very close to how we power and read RFID chips. It's nothing new.

Intel revolutionizes the electric world!

Not really.

In 2007 Marin Soljačić and his assistants successfully made the first efficient non-radiative power transfer at a distance of 2 meters turning on a 60 W light bulb. Energy transfer was 40% percent efficient.

This had to come. They might only be able to power a lightbulb now, but I can't wait for it to be able to power a laptop

Would it be possible though to use a sort of magnetic equivalent of a cantenna to steal wireless power?

I rather not have wireless power, there's enough radioactive waves my brain has to endure.

There are no radioactive waves, it's done using magnets, which like it or not you're subjected to every day from gravity.

Assuming by then we don't come up with something that prevents the aging process. :p

i do rather went to slow down the process rather then to stop aging :)

it doesnt bother me to be elder at some point , but i hope to stay healthy

mmmm 2050 we would had intel ultra small die shrink 2nm which will have enogh cores for every function of the pc

and ATi HD55870X8 :p

will neowin stand the test of time ..... ?

i would be 4ever with neowin ;) who about you guys :D

Oh c'mon, the human body isn't weak. Our bodies endure different types of radiation everyday. UV radiation for example, and even cosmic radiation (to an extent). Also, the technology is based on the use of magnetic fields to generate electricity. That doesn't have any longterm or short-term effects on the body. Heck, the Earth is one giant magnet generating one giant magnetic field. We're still alive, no?

Don't let the wind blow off your tinfoil hat! :)
