I guess this is a proper forum as almost any on this site would be on this topic.
Anybody heard about this yet? I just heard about it last week and I guess its been in the works for awhile.

saw a bit on the tube where a company had....whatever it is, in the wall and all you have to do is place your electronic device next to the wall and it works.

120v sent from the wall via MI. WOWOWOWOOWOWOW :yikes:

What if I want to play in the middle of the room?

1984 is definately catching up!!

So now I can electrocute myself without even putting anything in the socket??? That's progress!

Like controlled lightning? They're going to have some serious issues with safety, I think.
 
Yes... Tesla did do it. From what I've heard Tesla wanted to supply free wireless electricity to the whole world. Rockefeller was funding his research and when he found out Tesla wanted to do it for free and he wouldn't be making any money on it he quickly cut off Tesla's funds. I could be wrong on that but the that's the story I heard from one of my electronics teachers.

I think that it only moves if it "see's" a reciever which would be in the new products that use it.

Until we are all sure, I suggest putting on your thermal electric underwear on the back porch.:D
 
In almost every way, Poor Tesla was abused and betrayed by just about everyone he tried to do business with. Edison was a real pr**k to him.

Nuts? Check.

Not as good of a salesman as Edison? Check.

Utterly freakin' brilliant? Check. :smoke:

Its true. Edison held Tesla back and undermined him whenever possible (or so I read) Ive read Edison was a big pr**ck in general though. As were many of the great minds of our past (and present).
Alexander Graham Bell was a huge one also. Egotistical and bigoted beyond imagination by todays standards.

You know, People call me a pri**k all the time. :D

Actually though, Tesla basically created a big Spark plug.
The idea was there but this is far beyond that.
 
Isnt this the same technology that Apple uses with their Macbooks and their chargers? It consists of small switching power supplies with tiny transformer core halves in the charger cord and the laptop. You stick the cord on the laptop (it is magnetic I believe) and it completes two halves of a transformer, electromagnetically coupling at a high frequency switching speed.

In essnce, taking a switchmode power supplie's transformer and cutting it in half, one half for the cord, the receiving half in the device.
 
While this is cool, I doubt it would have the power needed to drive a tube amp. Even if it did, I see all sorts of trouble with the tubes picking up the massive electro-magnetic field. Also, while it may be a newer technology, I think there are losses that may make it more power hungry. What I mean is it would take more than 100w to light a 100w light bulb. Would be great for smoke detectors and clocks, for a stereo I see little benefit. My 2¢. John

Apple's connector is just a magnet that holds the cord to the small contacts. A good step in the right direction, but not quite what this system is. I am an ex-Mac Genius, and wondered why they never used an induced system like a cordless toothbrush does. That type of thing will be here soon. In fact the new Palm has a similar charging base with no wires connecting. This is very short distance. John
 
oh, I thought Mac had an induced transformer system, I guess maybe I was thinking of something else. I know they are doing the same thing with PDA's and cellphones as well, where you lay them on a charging mat.

I wonder how they do it out in the middle of the room though?

Isn't that one of the things Tesla was trying to do about 100 years ago?

Tesla claimed he had mastered wireless transfer of energy. Since the contents of his lab were seized by the government upon his death, we may never know for sure what he really accomplished. There are fantastic eyewitness accounts of some of his experiments in Colorado. Explosions and huge balls of light.

There was a huge rivalry between Tesla and Edison. Edison was pushing for DC current, and Tesla invented AC, which had many advantages. AC current could be run through transformers and the voltage stepped up or down as needed. One important advantage of this is you can send AC over very long transmission lines and step up the voltage to make up for losses in the transmission lines. It is much more difficult to do that with DC current.
Edison arranged a public demonstration, where he electrocuted a dog with AC current, to "prove" that it was dangerous. In actuality, the AC tends to cause your muscles to jerk, and throw you away from the source of the current, where DC causes your muscles to lock and hold on. DC is far more lethal. What an a**hole. Westinghouse was Tesla's champion. I believe he built the first AC power plant.
 
I guess this technology will finally put an end to the Power Cord debate...:D


interconnects will be next :banana:

That's pretty much my understanding of the story, except it was actually J.P. Morgan that had been bankrolling the work.

Both J.P. Morgan and Westinghouse, as I recall. Westinghouse built the first 3 phase electric powerplant in upstate NY someplace in cooperation with Tesla and using his patents. Later on J.P. Morgan was Tesla's benefactor, but Tesla was having a hard time getting any of his projects to a point of demonstrating potential commercialization and Morgan pretty much cut him off. Tesla was a nut job. He was fooling around with x-rays, not understanding the harm they could cause. He and Samuel Clemens (Mark Twain) would sit around Tesla's lab and blast x-rays through their brains for like 15 minutes or more at a stretch because they liked how it felt and thought it was good for them. Yikes!
I read a very poorly written but interesting nonetheless biography of Tesla about two years ago... by Mary Cheney (her last name stuck with me :eek: for some reason). I picked it up on the bargain table at B&N for a couple of bucks.
