SAN FRANCISCO (AFP) - 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."

That would be great for wireless speaker systems. I wouldn't need all these wires for my Bose surround sound. What a pain!

I've been reading with interest about this for awhile.
Also, get ready for all your battery powered devices to automatically get re-charged wherever you place them in a room that has a power sender.
Yeah! You will pay a high price at first but like everything else, competition and ample supply will lower the prices.

I hate to be the one to break this to him, but it is the same thing. It is called an electromagnetic field for a reason. A magnetic field will induce a current in any conductor capable of sustaining it. Electricity creates magnetic waves and vice-versa.

I won't be amongst the first to adopt these...but I do like the idea...uncabeeil where are studies that have shown this to be dangerous to human health?

There is a very strong correlation between the EM fields near high tension wires and cancer. Those who live or work within a 1/4 mile of high tension lines have a much higher risk for many cancers.

I've heard that too, and its too early to know the effects of it. They aren't able to prove the effects until years later, if they even can, like cell phones and brain cancer.

The afects of sin in our live or the the lives of others and/or stupidity have a better chance of killing us than magnetic fields.

How many MRIs have been done? The magnetic field associated with an MRI is magnitudes larger than that of a transmission line, and there is no evidence that an MRI causes any physiological damage.
It is similar to low level radiation exposure. Nobody really knows the effects of it. They can extrapolate backwards from evidence of large level doses, but that doesn't seem to correlate.

MRI's are relatively short term exposure in a controlled environment.. I'm talking about long term exposure in the home/workplace along the lines of 40 hours per week at work, and/or 24/7 at home.
