Nikola Tesla was a professor of MIT.

the next breakthrough! bravo!

Nikola Tesla was not Croatian.Nikola Tesla was born an ethnic Serb in the village Smiljan, Lika county, in the Austrian Empire (present day Croatia), on 10 July [O.S. 28 June] 1856. His father, Milutin Tesla (1819-1879), was an Eastern Orthodox priest.Tesla's mother, Đuka Tesla (née Mandić; 1822-1892), whose father was also an Orthodox priest.

Exactly.

The efficiency would depend on distance the further the less efficient, so I'm not sure if it's worth the extra cost.

Oh and yes the final statement is exaggerated but the fact is this concept is based on coils and transformers do use electricity when left plugged into a power source and I noticed in my last post here that to power one 60 Watt light bulb at 7 feet they do not mention how much energy it took to do it...so if it takes more than the 60 Watts how can it be efficient? Or is it simply it takes more energy to transmit electricity so they don't want to say...I think that's most likely the case.

waw, that is fantastic

In August, September and October of 1979 there was experiments done in Platteville, CO. for the purpose of seeing if Ohmic heating the ionosphere would/could aid in beaming electricity to a satellite and back to earth...there was also further testing done at Carpenter, WY. directed toward monitoring the transmissions from their LES-8 satellite at 249.2 MGh which was recorded between the time of 0256 and 0335 UT on March 12, 1980...this and more can be found in (ITS annual technical progress report, volume 979, issue 80) page 108 is where I was reading this and....potential RFI/EMI effects of a proposed Solar Power Station (SPS) to convert solar power energy beamed at 2.45 GHz and back producing 5,000 MW on Earth.

Why is TEDx not addressing this!!!!!!!!!!

WiTricity was going to happen for long distances maybe space to earth in next some decades. Remember the name "HALLEY" are going to do it.

only if this were invented back in the days, then all our setup would have been completely different. every device would come with building wireless electricity receiver like we have Bluetooth and Wi-Fi now, and there wont be literally any cables

I think Safe is a very relative term with wireless energy. It depends on many factors and potential uses. Military has had a death ray for decades, what do you think that is.

Seems WiTricity is taking credit for N.Tesla's invention in 1903. There is actually a copy of Tesla's Wardenclyffe (Shoreham, NY) Tesla Tower which ran out of budget and was never completed.

they take credit and they don't want for real to give it for free,it supose to be free from long time ago when Tesla succed to give electricyty to a few hundred km for free,what are you talking about with that unfinished tower was a resonance canon wich once hit the Ozone layer the electricity was trasmited to all glob! same base but huge scale and for free.

If the efficiency is dependent on the distance between the induction coil and the target, there is lot to work on, isnt there?

The lightning revelation 😂 Preach! Too late to change my economics degree, I wanna go into science, you know, an engineering degree, or maybe just go into engineering after all the brilliant visionaries dropped out.

The applications are astounding. If a house was built with repeaters, could you basically have a wireless 110v outlet anywhere? Could an arc welder ditch the cord? What is the limit of power that can be transferred this way? Of course the next obvious question is how can its use be metered and controlled. What keeps a neighbor from stealing your wilectricity? Do independent systems compete or co op with each other? If a whole town converted, will there still be the need of step up and down transformers from the electrical source? Does the danger increase with the capacity of millions of watts that a city would use?

Elijah Ayeni Although intuitive analysis you have, this would not be a good idea, as the available bandwidth is very small. Having a transmitter in an apartment, you would only need a sheet of low permeability material in the wall, very cheap. For a house, the radial field lines are sufficient to a certain proximity, then falls off, there would be no stealing of power.

One last point is if magnets can produce safe movement of power, then why do we need to make electricity anymore?

I especially like the electric roads idea. But, how would you charge drivers for the electricity they use? I guess you could have some sort of tax and everybody gets to use the electric road without further payment. If the price of electricity drops much further, then this would probably be the way to go.

Well, Fi in WiFi means Fidelity, or the quality of a signal. In this case, we don't care about the signal quality (as much as we do with transmission of information). I agree that WiTricity is not very catchy though!

Here we are, in 2024, nearly 10 years after this video was posted, and more than 15 years after MIT researcher Marin Soljacic invented this technology, and Witricity technology is still not widespread and lost the standard battle against Qi wireless charging… It is really a shame that Apple didn’t adopt this wireless charging technology because it seems so, so much more convenient than Qi wireless charging, and could have scale across all types of Apple devices…

It make you wonder how fast it would charge an electric car. Would it be as powerful as a Tesla Supercharger? Hmm

Radio Bikini cites ?

Denser and softer metals are the secret, think about it if i have a metal that is soft it will have a low resistance so if i overload it with electricity electricity will fly from a tesla ark. But if i could create a super dense metal i could create a bigger resistance and a bigger feild of area. The tricky part is technology all current technology will pretty much be useless it will take a reinvention of technology that has a recieving coil and the guts of that technology is made of soft metals with instead of transistors to slow the electricial flow, flowsistors to upscale the electrical flow (short circuit/softer metals the further in you go) problem is everyone will steal electricity then and there will be no money to be made plus we need fusion which can be achieved by the same meams denser metals to create bigger magnetic feilds and or a different form of magnetic ability that uses denser metals superconductors.

induction on steroid!

From the website : "magnetic resonators that efficiently transfer power over LARGE distances via the magnetic NEAR-field" !! :) .(where LARGE distances so far is a few inches) How can these guys pat eachothers backs and get geniouses-prizes for "discovering" and "inventing" something (resonant induction) that's been known for 100+ years ? It's very Edison - taking out patents and selling things others discovered and calling it their own. At the same time lot's of other companies are doing the same thing, only they don't try to take credit for "the great discovery". Like Toshiba f.ex. been charging buses this way on bus stops on a Japanese island for many years. It's all marketing - and you guys at the MIT should be ashamed it - when you all know deep inside this is nothing new The only reason it's not more common is that for most electronics, engineers at the universities has been thought to avoid resonance at all costs - thereby these phenomenon has not recieved the attention they deserve. But they have been researched and discovered and put to use again and again for at least a century. Incredible if they could get a patent - it's not on the principle, but probably on the specific device, using resonant conduction to charge a cellphone or car. Great that a product gets available for others than garage tinkerer that make it themselves, if the prize is anything near the simple parts it consists of, but I have a feeling this costs an arm and a leg because it's so "new" an "unique", such an incredible discovery and engineering accomplishment.

the principles of tesla, wireless exists 100 year. mit is stupid or what,, they did not want to commercialization, for years is in truth now as people are getting tired of the tegnologia that we are using the principles of nicola tesla is another thing, it's like tesla told Eddison one time that this was theirs but the future belonged to them nicola tesla and I'm realizing that it's true if writetihouse had not destroyed that big antenna that history relates, nows had that large scale technologies and more advanced

Btw we can transfer electricity wirelessly using microwaves theyv done it in japan and now in tasmania. And thats not to mention how they seem to forget tesla had a better idea originally. And he was serbian!
