- inactive, on 06/14/2009, -1/+62Nicola Tesla was able to build this in a cave!
With a box of scraps! - inactive, on 06/14/2009, -2/+38http://www.youtube.com/watch?v=N7NAD-RtGk0
Intel have been working on a better version for several years now. The one in the video makes use of about 80% of the energy at a few feets distance, well enough to make power chords in homes obsolete. - misternils, on 06/14/2009, -0/+33This was a pretty bad video. Those guys didn't have very good presentation skills. I learned nothing new about Tesla and i know very little to begin with.
- yocouchdigga, on 06/14/2009, -0/+32I bet Tesla could beat the crap out of these two, at the same time, while throwing ball lightning out of his ass.
- emanpa68, on 06/14/2009, -1/+28Tesla didnt build 2 coils, he used electricity to induce a specific frequency on a magnet, I believe 30hz, and it was able to travel long distances and make another magnet vibrate at the same frequency to regenerate electricity (by converting the physical motion to electricity)... I'm sure a genious like Tesla would have smaked his head watching these guys butcher the science he worked so hard on.
- SteveHamn, on 06/14/2009, -0/+26Wow these guys are dumb. You can't get test equipment to measure 10kHz? WTF. 300 Watts from 30kW from only 15 feet? WTF. Tesla didn't simply put two Tesla coils next to each other and expect the ambient energy to be transmitted, it was a lot more complicated than that.
- Elsewhere42, on 06/13/2009, -5/+22Sorry conspiracy guys... the power transfer is still only 1% efficient.
If someone can get that to 95%, then we'll have something. - drGt1987, on 06/13/2009, -1/+17Well, if you blame those inventions for brain tumors and birth defects you should start blaming on radio waves too...
- raydeen, on 06/14/2009, -0/+12His power level was over 9000.
- Protonz, on 06/14/2009, -0/+12OMG they discovered induction! Now the electric toothbrush that I have owned for a year can finally exist!
Of course energy can be transferred through magnetic fields. - ligyron, on 06/14/2009, -1/+12Just don't take off your tin foil hat and you'll be fine
- inactive, on 06/14/2009, -0/+11As I understand my history Morgan cut off Tesla's funding when he found out that he couldn't put a meter on the wireless power transmission device Tesla was working on. That and he found out the amount of money needed to complete the project was around one order of magnitude greater than what Tesla originally told him. And he had already given Tesla a metric ass ton of money for the time. Not because Marconi beat him to the punch. Tesla is one of my personal heroes and one of the reasons am in school for electrical engineering (aside from wanting to make good money out of school) .
- inactive, on 06/14/2009, -0/+10You're a ***** idiot.
- icecoldtrashcan, on 06/14/2009, -1/+9You have been gravely misinformed. You can think of radio waves as being a form of light.
- jman583, on 06/14/2009, -0/+7With wireless electricity, it might be safer to not wear tin foil hats.
- scoottie, on 06/14/2009, -1/+8We will see, not only if its possible but even if its worth it. Tesla was amazing too bad he didnt get the credit he deserved.
- raydeen, on 06/14/2009, -0/+6Tesla invented AC running at 60 hz (made it easy for the power company to charge per the minute). Edison wanted DC.
- Killerfilm, on 06/14/2009, -0/+6The U.S government seized much of his documents and declared them top secret. He's not just some weirdo, he was a scientist...of course he wrote things down. Unfortunately though, in taking his documents and making them secret the government only managed to turn what was probably interesting and useful inventions into mythical machines that people think can do everything from free energy to time travel.
- ichbinladen, on 06/14/2009, -0/+5Tesla 1, internet guys 0
- Brak710101, on 06/14/2009, -1/+6This is the second time I have read one of your retarded comments.
Twice I have regret it. I looked through your comment history and realized that either you're a troll or actually retarded. I mean really, read your own history, you use "...I'm extremely interested in science and programming so maybe it's easy..." so many times its unbearable. - Killbot2015, on 06/14/2009, -0/+5http://www.ncbi.nlm.nih.gov/pubmed/15255560?ordina ...
EMFs don't cause cancer or birth defects... where do you people keep getting your misinformation? - CATSCEO2, on 06/14/2009, -0/+5Reply button. Use it.
- Mouser58907, on 06/14/2009, -0/+5Nikola Tesla "invented" AC current. His "boss", Thomas Edison, wanted DC current.
- scoottie, on 06/14/2009, -0/+4not in this nanny state
- Darph.Bobo, on 06/14/2009, -1/+5Done! Will you accept exceeding 95%?
http://www.witricity.com/pages/faq.html - MasterGrief, on 06/14/2009, -0/+4+1 Science
- inactive, on 06/14/2009, -0/+4also a lot of what they were saying wasn't correct
- tomalakborg, on 06/14/2009, -1/+5gotta love the inverse-square nature of the universe... I'm guessing they discovered that the power received by their little *****-shop had something akin to that
- chokeaduck, on 06/14/2009, -1/+5And you base that theory on...
- case116, on 06/14/2009, -0/+4Nikola Tesla and you
- blipblopblip, on 06/14/2009, -1/+4It's because they're doing it wrong, they need to use the natural frequency of the object at the top of the pole, not a toroidal coil.
The energy needs to resonate between with the balls on the top and the ground at the natural frequency of the balls. The energy is scalar, it goes in and out, it's a longitudinal wave. These guys have wound a coil which is making a lot more interference than necessary and producing spurious high frequency radio waves. They're just receiving those radio waves. - Nicoon, on 06/14/2009, -0/+3Yet when Tesla is mentioned nobody seem to know who he was. Everyone knows who Edison was on the other hand.
- morepowerr, on 06/14/2009, -0/+3More like to send energy over waves like a radio. You set up a you station and send power to every one how had a receiver. You then tune you receiver.
- MasterGrief, on 06/14/2009, -0/+2Well, yeah, these people don't seem to be doing a very good job of things, but hey, at least they're trying. I wish I had access to the equipment they did and the time to mess with it.
- MasterGrief, on 06/14/2009, -0/+2It was a reference to Iron Man.
http://www.imdb.com/title/tt0371746/quotes - GawtMilk, on 06/14/2009, -0/+2At an accredited college? With actual scientific materials? Or at homeopathy.info? I'm just wondering. I had heard the opposite. Not necessarily with this technology (which is extremely inefficient and badly designed), but just in general. Have you seen Intel's approach? Way better, in my opinion.
- Crocuspokus, on 06/14/2009, -0/+2These guys have a terrible presentation. Wardenclyffe was built to take energy from the ionosphere, but Morgan didn't think he could make money by giving people free electricity. Bastard!
- MrYellow, on 06/14/2009, -0/+2This doesn't make anything obsolete. They have two fairly large directional antennas sitting two feet apart, transmitting electromagnetic waves. There is nothing new or practical about this idea. The basic principals of this are described by the Friis equation. http://en.wikipedia.org/wiki/Friis_transmission_eq ... The only situation where this becomes practical for home use is with proximity charging of small devices such as your cell phone or iPod.
- Memnochxx, on 06/14/2009, -1/+3lol!
- homercles337, on 06/14/2009, -0/+2Uh, this is, uh, what, uh, New Jersey, uh? Yea, uh, New Jersey. I have NO respect for idiots that speak in public without sounding like a ***** idiot.
- craggatt, on 06/14/2009, -0/+2+1 digg
- TymonBrown, on 06/15/2009, -0/+2hey nils i love you. but yeah i agree
- wolfkeeper, on 06/14/2009, -0/+2Thing is, the wireless power transmission they're using is near field. Near field ISN'T inverse square law.
The Witricity guys demoed 60% efficiency at ~6 feet with ~1 foot coils. - grantmoore3d, on 06/15/2009, -0/+2So, they inadvertently induced some electricity in the stupidest way possible... good "experiment"
- captainnico, on 06/14/2009, -0/+2They forgot to direct the charge through ionized air using a beam of ultraviolet light. Any tesla geek knows that's how the transmission system worked. :P
http://www.teslaradio.com/pages/wireless_102.htm - craggatt, on 06/14/2009, -0/+2It'd be a lot cooler if you did! :)
- Killbot2015, on 06/14/2009, -0/+2Tesla has 3 statues of him in 3 different countries around the world and his face is on money in 9 countries. Edison just had his house made into a museum...
Tesla got credit, just not during his own lifetime.
And did you see The Prestige? He was portrayed as a god in that movie. - craggatt, on 06/14/2009, -1/+3@sockerblt, Power chords are best kept in a band rehearsal space, but i don't think you need to rule out playing electric guitar in your house just because there is wireless electricity.
- Darph.Bobo, on 06/14/2009, -0/+2It's here. It's real.
http://www.witricity.com/index.html - MrYellow, on 06/14/2009, -0/+1"wireless electricity" is passing though our bodies all the time. They are called electromagnetic waves. The only difference between light, your cell phone, or this, is the frequency and wavelength of the wave.
