Tesla who ? Intel with new tech "wireless power"
If having a chip in about 95% of the worlds computer isn't enough, now they want to send you power.
"Wouldn't it be fantastic if we didn't think about where the power was coming from and the power was everywhere?" he said. "No cords, no batteries anymore."
Mr Rattner envisaged a scenario where a laptop's battery could be recharged when the machine gets within several feet of a transmit resonator which could be embedded in tables, work surfaces, picture frames and even behind walls.
Intel's technology relies on an idea called magnetic induction. It is a principle similar to the way a trained singer can shatter a glass using their voice; the glass absorbs acoustic energy at its natural frequency.
At the wall socket, power is put into magnetic fields at a transmitting resonator - basically an antenna. The receiving resonator is tuned to efficiently absorb energy from the magnetic field, whereas nearby objects do not.
It does make one wonder about troubles this might pose to health in the realm of EMF however.
"Now the question is if it's feasible or not. It's exciting that they're also inspired and it seems closer to reality every day."
Star Trek science is no longer in the future.
1899 At Colorado Springs he (Tesla ed) built a huge magnifying power transmitter, based around a massive Tesla coil and an antenna that was 200 feet tall. It was capable of generating voltages of 100,000,000 volts. Tesla used this apparatus to light banks of light bulbs over 20 miles away.

World_Groove, I like this story. It's good stuff.
I think the biggest problem is going to be that ghost hunters are now going to find ghosts everywhere! They supposedly believe that high EMF frequencies mean there are ghosts nearby.
Anyways, sorry for the sidetrack World_Groove, this does sound interesting. I wonder if anyone knows what the "safe" range for EMF readings are?

I actually have an EMF meter, the needle goes into the red at 2 milliGauss. To give you an idea of what that level is, the top and bottom of my Mac computer at the surface read just over 2 M.G., A microwave and toaster go way over 5 M.G. (the max of my meter) a microwave EMF reading can be taken on the other side of a wall.
But.... who really knows what if any damage is caused my EMF, I can't recall what the safe Goverment standard is.

World_Groove, I like this story. It's good stuff. A safe range is 800 milligaus, by Who, though many are stating 1 to 2 milligaus is dangerous. I completed some EMF and ELF surveys for some schools around the lower mainland which hit the media in the last year. There is no clear indication of harm, though newborns and children should not be anywhere near overhead Hydro lines as a precaution. EMF is dangerous, it is just at what level, as the force field can pass carcinogens in the air through your body.
EMF for Hydro lines and Cell phones are completely different as well.
EMF for computer monitors though are safer from a viewing distance of two to three feet. Try and set a meter near a photocopy machine, now there is a surprise for ya.
You should know EMF's are everywhere, buildings with faulty grounds, and neutral lines crossed or joined can emit really really high levels as well. So it is not just computers. For sake of argument the earth is one big EMF, though DC, where for Hydro Generation purposes here in North America is is AC which is the main point of contention. Europe is on DC current and a lot of studies are from Europe where fear mongering is rampant, most likely by the Green Party, all have their agenda and disagree with each other, and fight tooth and nail on who is more accurate in their studies.
Scientists doing long term studies for the last 2 decades are inconclusive.
To calculate true EMF though, you need one that is omni directional x,y,z and then you need to calculate the root mean square calculations, to get a comprehensive reading, many untrained in using it, panic at high readings, when they are not looking at the big picture, and do not do the math. Telsa is just another form of measurement of Faradays Law. Milligaus is where it's at Baybeeeee!
Anyway, this is Cliff Clavin, Signing off, I got Breakfast to make, laundry and housework.
Don't worry about this new computer tech stuff. It still has to pass ULC and CSA requirements.

Great Post. Feel free to teach us more after Laundry, Housework, and Breakfast......

Barry excellent EMF summary. France is on High voltage DC, rest of europe mostly AC. Let's add one thing: In a laboratory tests prooved that cats can fell DC fields, their hairs start vibrating. What vibrates in humans I hope not the pacemaker.

There was a New Yorker article a few decades ago, The Annals of Radiation, which was about twenty pages long and went into a lot of details concerning the link between 60-hz emf and childhood lukemia ... the author's findings were systematically ignored, and now have pretty much faded off into obscurity ...
I did ask a friend of mine once, an electrical project engineer who's professional duties involved designing high-power industrial installations, what he thought of all this emf stuff. He replied that he didn't think it was a very good idea to live within half-a-mile of a high-power transmission line ...

Actually after a 50-100 meters EMF radiation is pretty much background by then. Many want their high voltage lines buried , deep, deep, deep and shielded, but no one will do it because of the expense, and PETA would get their Panties in a Twist. cause the gophers and worms would be affected.

Well, I guess we've got our choice then - Spotted Owls or gophers and worms ...
Not much of a choice actually ...

Rest assured Owls and any other animal avoid these areas like the plague. If one is ever under a high voltage tower, you can hear the electricity crackling through the wires, quite unsettling for man and beast.
