Intel's Wireless electricity!

Uh, yes. Nicholas Tesla did this back in the early part of the 20th century. Basically you put up a big power source radiating EMF and a receiver in the car. This powers the car at a distance of up to a mile away, with no onboard power source. Not terribly efficient however (radiating energy in all directions), and no way to meter your usage. (If you can't bill your customers fairly, you can't make money).

There was a development last year I think where they significantly improved the efficiency somehow. Maybe this builds on that work. Billing could be solved by tamper-proof electronics on the receiver unit.

 

I hope we know what we're doing. What would cities and skies full of such magnetic fields do to migratory wildlife?

 

Another question would be, is the magnetic field strong enough to affect magnetic objects in the vicinity? Will it physically draw my pen towards the transmitter, screw up my HD? It has to be relatively strong to transmit energy.

 

This would be great for close-range charging (like a transformer). One of the men's electric razor companies already offers this on some razors. From longer distances, the efficience drops inversely to the square of the distance though. At a short distance, this could be great for recharging though.

Lol. at Nikola Tesla's pre-magnetic inductive electricity!!!

Possible but not practical for vehicles. The method is convenient only where the source and receiver can be within a few meters of each other (so you'd need coils capable of hundred of kW in the roadway), and where you can avoid materials that are attracted by magnets (that is, no steel rebar in the road and no steel in the cars). See
http://en.wikipedia.org/wiki/Wireless_energy_transfer#Resonant_induction

For recharging an electric car it's better just to use a conventional connector.

 

It would be trivial (from an engineering perspective not a cost perspective) to bury power cables in the road bed and power your car with an inductive pick up.

 

small companies have had working versions of this for at least a few years now. But I don't know how you sell a device that radiates a room and then ask employees or home consumers to spend most of their life in it.

Intel just has a big name. Still no product.

 

I'd certainly like to see a standardized inductive charge pad that you can park your EV or HEV vehicle over and charge automatically without physically pulling the plug over to the car.

 

Well, if there are people who complain about living near powerlines and THEIR magnetic fields, just wait until this gets near more than just a few scientists.

I sure hope I can take advantage of it though...

 

There has been one guy who returned his TCH for a LE because the inverters emit too much EMF inside the car and feel not safe.

I'm all up for new technological advances... however, and this could be my ignorance speaking, this one really really makes me nervous. It's certainly cool. I've seen the episode on the History Channel about Tesla numerous times and it's just as interesting each time... just makes me a bit nervous.

 

So ummm I guess small fluctuations in this 0.5G field we live in makes that much of a difference? Oh wait maybe you should tell those near the magnetic north pole where its upwards of 0.6G, or those far away where it can be as low as 0.3G.... I don't get it... seriously. beyond 2-3 milligauss is harmful, but 200x that amount is ok.

 

I sincerely hope this guy never has to take an MRI scan during his life. EMF gradients on those machines are measured in Teslas, where 1T = 10,000 Gauss! Modern MRI scanners are rated around 2.5T or more.

 

I've always wondered what would happen if PROOF arose that communication-grade radiation like radio waves caused cancer. Coverup, or end of broadcasting? Still not sure which way it'd go...

 

Even stranger, imagine how it could possibly change the course of evolution on the planet. Imagine waking up one day, and you hear the song "I've Got You Babe" in your head!

 

I find this interesting...
"Previous wireless power systems consisted basically of firing lightning bolts from sending to receiving units." LOL!!! Bull.
Nikola Tesla had it right the first time. If anyone read his biographies and works he states that the discharge (the plasma emitting from the electrode on the top of a Tesla Coil) was not what carried the majority of the current, nor was it a desirable effect, but that it was the EMF emitting from the coil itself. I have verified this by my own Solid State Tesla Coil. Intel is just repeating a 100+ year-old science experiment. In fact he had done experiments that prove (and MIT back up his claims) that for long distance transmission of electricity, wireless transfer is far more efficient than wired. It isn't just "radiating electricity in all directions". It is sending out a field of electromagnetism that, unless picked up by a receiver and USED, hardly has any waste other than maintaining the field (reference eCoupled).
Also, it is extremely doubtful that magnetism causes cancer. Tesla spent his entire life surrounded by immense Electro-Magnetic fields and he never had cancer.
Bottom line - this technology won't get out the gate. It will get killed for the same reason Tesla got excommunicated from the science community - you can't meter it.

 

Happen to have a link to this?

You have to admit it is a bit strange to make an assertion like this, I mean if you all of a sudden flipped on a receiver the energy just starts flowing like no ones business? You have to create some sort of omnidirectional field for this to be true, and for that field to do any work means that it'll have to have the same strength in every direction which means a lot of wasted energy.

Did they test for cancer in the late 19th centure/early 20th century?

Umm, how do you figure you can't meter it? You still need to plug in a device to start the field, and that can be metered. This isn't about long range power transmission where someone can just steal it.

 

But unlike human bodies, hard disks *are* affected by magnetic fields.

You definitely don't want any strong magnets around your notebook computer or desktop harddisk or car navigation system.

Is Intel waiting for when all computers will have switched to flash drives for storage? Otherwise it doesn't make any sense to me.

 

So how does an MRI work when a magnetic field realigns the magnetic moment of every molecule it happens to be scanning in your body? They might not be harmful, but obviously they effect your body.
