Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. In early days, electricity was considered as being unrelated to magnetism. Later on, many experimental results and the development of Maxwell’s equations indicated that both electricity and magnetism are from a single phenomenon: electromagnetism. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others.

The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field.

When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb’s law. Thus, if that charge were to move, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positive charge from an arbitrarily chosen reference point to that point without any acceleration and is typically measured in volts.

Electricity is at the heart of many modern technologies, being used for:

electric power where electric current is used to energise equipment;
electronics which deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies.
Electrical phenomena have been studied since antiquity, though progress in theoretical understanding remained slow until the seventeenth and eighteenth centuries. Even then, practical applications for electricity were few, and it would not be until the late nineteenth century that electrical engineers were able to put it to industrial and residential use. The rapid expansion in electrical technology at this time transformed industry and society, becoming a driving force for the Second Industrial Revolution. Electricity’s extraordinary versatility means it can be put to an almost limitless set of applications which include transport, heating, lighting, communications, and computation. Electrical power is now the backbone of modern industrial society.[1]

  1. @iyiyiy12345 wow you really didnt get it. you think that the only thing this technology could do for us is that we wouldnt have to plug cables anymore? omg get the big picture: no wires (not only in our houses, but in the streets, everywhere), no batteries (no environmental issues) and a much more efficient way of transfering energy. And all of that for much less work and money. You really dont see the potential of that?!

  2. @grandexandi He was working on electricity sent like a radio wave, but when his backer realised he wouldn't be able to metre the electricity used, he withdrew his financial backing for the project which was then dismantled. Then Tesla's lab was destroyed & was ruined.

  3. @xinlo huh? but wireless information has been a reality for quite some time now… i mean, radio, tv, phones… right now im sending this comment to youtube through my wireless internet connection

  4. @grandexandi
    Yes but to send information you have to use a code and send bursts of energy. The way I see this technology is needing to warm up and such. I guess what I'm saying, witricity doesn't affect informational transfer…
    Eh, maybe I just have have my thoughts screwed up. I did, after all, say that first one at like 2 in the morning where I live…

  5. what I want to know is, what is the effect of this technology on devices that use magnetics to store data? Will a WiTricity transmitter that's strong enough to transmit energy at 8 feet efficiently be strong enough to corrupt data on my hard drive? Or will the fact that it only transfers energy to devices that have the same resonance mean there won't be an effect at all?

  6. i have been waiting for this for a while now. imagine no more extension cords, no lack of power points, possibly even electricity in places that are now way off the grid. I know it defeats the purpose, but imagine going camping in the bush and having power to heat water or for a radio without a generator. i think this will be awesome

  7. induction yuck! tesla didnt use induction for wireless energy transfer at wardenclyffe tower he used scalar waves (longitudinal waves) out of near field non electromagnetic waves with 99.9% efficiency
    there is a better way meyl (.) eu
    please listen what this guy is doing is nothing new
    imagine a world with wireless electricity everywhere it is possible spread the word

  8. @rathat48 I have studied his work and the work of others for many years honestly you should see what prof meyl has done. And I know tesla was using induction for the magnifying transmitter that's obvious he has to, but actual single wire (or earth) transmission is scalar you'll see what I mean if you watch meyl's videos, unlike pathetic john hutchison which I believe is fake. Please be open minded about this.

  9. @romxxii Also the problem of will it interfer with radio, tv, cellphones, laptops, etc. Also can they do it without having significant loss of power over a long distance?

  10. In Frankenstein they got electricity out of the air cause by lightning and that was written hundreds of years ago but don't see people trying to utilize that is it possible to get enough electricity from that which is already in the air without having to produce it?

  11. they didn't come up with shit, anyone that has a basic knowledge of a transformer unit knows that this is nothing but a stolen idea which is going to a dead end. They could reach a distance of 100 meters if they used big enough coils, that's not a wireless transfer because the losses "energy to efficiency" is higher then 50%. This fake "wireless transfer" has been used for 100 years inside every transformer, lowering volts from higher to lower values, ideal use because of the losses

  12. @IdoCareForPeople It may dissipate in heat waveform, sice the magnetic field it generates can ionize molecules near it and make them move. I think we still have to do that, but we may already have a detector of full battery or just a voice recognoicer to turn it off if we say it….maybe…just suggesting…

  13. @hydrolito Lightning strikes for such a short amount of time… it's like having a water pipe hooked up to your shower, and expecting to get a shower from it by throwing a bucket of water at the other end.

  14. Don't the two coils need to be lined up in order to conduct to each other? Wouldn't that make this technology basically pointless except for static hardware such as desktop PCs or parked cars?

  15. @elmstfreddie no, your comparison is wrong. I would bitch if someone would reintroduce ham sandwich as an original idea. And this is NOT a theory and the USE of it isn't new either, Opening most devices you will find the use of coils in a device called transformer, mobile phone chargers work on that principle for example

  16. @lifemetall Yes I am well aware of transformers and their function. If this is so uncreative, why is it the first time I've seen it being used for wireless technology? And yeah argue all you want that technically they already work that way, but what I saw in this video was a new use of transformers I've personally never seen before and I'm sure many others haven't.

  17. @elmstfreddie well OFC many haven't seen it before, we aren't all electricians.Reason why this is starting to be used now is because creators of these devices started ignoring the fact that coil wireless transfer has enormous loses in power to effectiveness ratio.. I strongly appose this because this is not what nikola tesla had in mind when he said "one day electricity will be transferred wirelessly", if we accept this we will stop working towards REAL wireless transfer

  18. I think this is extraordinary, I really compliment this and other people that make all this wonderful things BUT never mind blessed people our governament will never allow this to go under production. We live in a shameless system that only see $ going in one direction. I feel very sorry that this will not go any where.

  19. I've seen Evatran Plugless Power and Qualcomm Halo use similar technology for EVs. Making things commercially scalable is generally very slow, unless some very dedicated, smart and innovative entrepreneurs step into the business
