Witricity

[mangalsuvarnan]

If you really want a good presentation of this innovative technology,

PLEASE visit ted(dot)com.

this dude just pisses me off..

[clk2000s]

good idea

[MrElectricstorm]

I had this idea years ago but dissent have 11g for the patient. I am cursed with so many great ideas but no investors to help with the patient cost.. I did this with my x-mass tree lights 2 years ago. and everyone knows how many fires happen a year with x-mass trees lights.

[spaceperbrains]

lol but there are still wire to the transfer...er

[santatigerclaus]

wha shucks Clem all ya goddadoo is live next to a high tension line- toss a couple bedsprings under it an hook a couple wires to it voila free juice - hook your house up!

[pkrska]

The source is so close to the gadget being powered that it almost is useless. Looks like 1 to 2 foot Max distance. And it is safe?

People who live within 100' of power lines get leukemia. So how is this safe?

[AvantguardX]

This means that we''ll have to attend "Battery Funeral Ceremony"

[AvantguardX]

Now , I have a question! If the power is being transmitted wirelessly or transfering the power does the electric meter registers it? I king a get the idea of Claude Shanon about source information and receiver. In this case the source and the receiver are connected through wire.

[candywrapp]

I rather have a remote and controller that is powered by the coils than the batteries being charged by the coils.

[d3dreaper]

This shit is kinda pissing me off... Nikola wanted everyone to have FREE electricity and is the reason he created his wireless electricity designs... HE INVENTED THESE DESIGNS TO BE FREE!!! They are not revolutionary and in fact is the reason we have radio's now... J.P. Morgan had to go and screw everything up didn't he...... "you can't put a meter on wireless electricity and thus you can't make a profit from it"

Tesla is probably turning in his grave right now....

[boussou]

@d3dreaper you're so right ...thanks

[mahburg]

@d3dreaper It would be nice to have free electricity. However, don't be so naive to believe that it will ever come. Electricity is a medium for transferring energy. You will be hard pressed to find many places that will give out free electricity (at least in large quantities.) What ever energy you use must first be harvested (solar, wind, fossil fuels, geo-thermal, etc...) then transmitted along materials that need to be fabricated, installed and maintained. No such thing as a free lunch.

[Maracachucho]

@d3dreaper Yeah because all them power plants run on unicorn farts right?

[d3dreaper]

@Maracachucho Just by that statement you show that you don't have the intelligence to have a legitimate argument with....

[Maracachucho]

@d3dreaper Can't say the same about you bro, that sentence really made me think about how free energy can be achieved without resorting to mythical creatures.

[d3dreaper]

@Maracachucho Ok then.. Real world example: What are you doing when you turn on your radio? You're picking up a resonant frequency you say? and you are not being charged to receive this "radio wave" you say? Well guess what wireless electricity is! Holy cow!! It's a resonating frequency that is being picked up, amplified, and used! What do you think started the radio transmission idea?

[d3dreaper]

@Maracachucho I'm not trying to say the materials are free... i know that in any possible idea that materials will always have to be purchased... It's the charge on "used electricity" that bothers the piss out of me. Especially seeing that the electrons that provide this energy don't get used up and disappear....

[Maracachucho]

@d3dreaper Ok fair enough, but you're overlooking all the resources that are needed to keep the plants up and running, both human and material, even with renewable resources like air or sun there is an upkeep for maintaining and/or replacing broken equipment plus the salary of workers. Sure someone makes a profit, but that doesn't mean you're getting ripped off.

And what's that bs about not using electrons? Do you want to keep them in a jar or something?

[d3dreaper]

@Maracachucho lmao I would LOVE to have a jar full of electrons!! someone isses me off and *POW*

My point about this is that

1: If the need for a power plant (in the sense that everyone thinks right now) is still necessary then the costs for maintaining it can be dramatically reduced by eliminating wires and telephone poles

2: Tesla had designs that could obtain electricity without chemical or mechanical means (i.e. towers that reached into the ionosphere... there's a reason it's called that)

[Maracachucho]

@d3dreaper Well too bad man, those electrons would go right through any jar you can put them in :(

I know of Tesla's genius work, and he indeed would have made made free wireless electricity possible had there not be financial obstacles in his way. But here we're talking about the wireless part, not the free part, and with the current power plants we have today, globally distributed wireless power would be unsustainable, because of costs. It's a real shame, but that's how it is.

[d3dreaper]

@Maracachucho

3: Tesla is not credited publicly for any of the modern day designs he originally created! (AC electricity is one of many and now you have power pant companies named "SoCal Edison" and such... yea...)

4: This became a fun debate from a rather irritating comment originally and i redact my comment about your intelligence :D

[Cradle2Venus]

What I would like to know is: when you have the initial station on - but no witricity gadgets are nearby, does it still have an operating cost or consume energy just being there?

a wired comparison - If I unplug everything from a power bar, the red power indicator on the bar is lit, but that one light is the only power being consumed by the power bar.

If we are just constantly broadcasting a constant energy stream we still have alot of work to do. That's like leaving all the lights on :P

[hlangagne]

REALLY GOOD AND NICE QUESTION!!

[Cradle2Venus]

thnx, thumbs pls :)

[johanssonmatte]

lets say if i buy a tv this year, and next year is witricity avaible. can watch tv wireless then?

[darqcheetah]

He even powered a small town by sending out electricity from his lab.....through the ground...wirelessly. SO yes this does have major implications if we can perfect it.

[darqcheetah]

All you nay sayers realize Tesla was able to do this 100 years ago with little to no loss of transference efficiency. He just never wrote down any of his designs. Read a book before you start knocking down solid ideas. Just because we can't do it yet doesn't mean we can't get it perfected to the level Tesla did.

[rodge002]

What if you combine solar power (on roof) and wind turbines(on roof still) to power these things? Environment saved right? Haha.

[gups76]

Witricity system is 45% efficient at transferring electricity. Can u imagine the magnitude of power losses worldwide just because people don't like wires for their mobile phones, iPhones etc.?

FOOLS!!

[Dave21superstar]

And can you imagine the environmental benefit of getting rid of disposable batteries and cables. Less crap being manufactured, used, and then thrown into landfill piles. Also... power losses? Uh, power can be given to us on a large scale via sunlight or mechanical generators. We won't run out. ..But i guess we're all fools right?

[gups76]

U knob! U'll need batteries even if this technology becomes mainstream. Take everyday things using batteries, ur phone, ipod or even cars, u telling me this technology will run all of those without batteries? Idea of Witricity is to charge batteries using wireless technology, not replace them. Also, when did sunlight become a major source of electricity? Mechanical generators burn diesel in huge capacity and cause harmful emissions. Fossil fuels will run out..sooner than u think!!

[Dave21superstar]

I said this reduce the amount of disposable batteries, not batteries in general. The idea there being reducing landfill and unnecessary pollution. Of course they'll still need batteries! but since they are being recharged and not replaced this is a non issue. There are other ways of generating electricity that don't cause emissions or burn fossil fuels. These are being constantly being improved. Solar energy, wind energy, tidal energy, thermal energy from the earth's core, nuclear fusion.

[gups76]

U said - can u imagine the environmental benefit of getting rid of disposable batteries & cables, NOT REDUCE! Anyway, then u said - Power can be given 2 us on large scale via sunlight or mechanical generators. I AM GLAD U REALIZE THIS IS NOT TRUE. ALTERNATE ENERGY SOURCES ARE NOWHERE NEAR ABLE 2 PRODUCE ENERGY AT LARGE SCALE, YET!!

All I know is, if there is technology that is 45% efficient at transferring electric current, its not even worth talking about because thats losing half the power!!!!

[d3dreaper]

i think you should take a look at some of the wireless designs on youtube... if you are able to build a small enough receiver circuit that is still efficient then you could entirely replace batteries altogether... the circuits are relatively simple to build so hopefully it they won't be too expensive  :-/ Tesla would've wanted it to be free... but wtf is free nowadays :(

[TheMathGuy]

I have to wonder how efficient this can possibly be though, unless you are focusing the signal somehow. If you're sending out the signal in all directions, then it will decay proportionally to the inverse square of the distance traveled, which would mean you're wasting a lot of energy in the transfer!

[theatheistinfidel]

Damn. :(

[aneeslk]

this will be useful for every power consuming stuffs

[bwillwall]

when do u thing this will be available?

[Grygory]

Idiots.... This doesn't "radiate" electric energy it's not a radiative form of energy, its magnetic. Electricity is turned into magnetic energy and then turned back into electricity at the destination device. think of this as a regular power generator "stretched". Also: Magnetism is not carcinogenic (not cancer causing)! So it seems safe!

[krix02]

Unbelievable..

[unusedsn]

I just cant believe in it based on the fact you cant eliminate the stream of power between power source and utility unless you use a worm hole or something

[melax69]

well it's not based on any kind of streams.

It's all about induction of magnetic field in coils, same thing you can see in power plans with their huge transformers changing high intensity electricity (low strain) into low intensity (high strain) electricity... w/e :P Physics is interesting hehe

P.S.

I don't know english so well so some science terms could be used wrong :P (flame shield 0n) hehe

[deepsinK]

Tesla demonstrated this tech in 1893 with a light bulb so why has it taken over a century for it to come into fruition? Mind boggling...

[kuorakuora]

It really hasn't been that useful until recently. Everybody has cell phones, etc now-- wireless electricity just makes sense.

[deepsinK]

Not useful until now, utter non-sense. Wires have been around since the beginning and I'm quite sure if people could have gotten rid of them way back then they would have done so already. I don't believe that has anything to do with WHY they haven't figured it out until now.

[kuorakuora]

Well, maybe useful wasn't the right word to use there-- but think about it for a second. It is not like people were walking around with cell phones or laptops almost a century ago. They didn't need to walk into a room and recharge anything they were carrying with them generally.

Don't get confused with this technology, there still will be wires-- but your everyday devices won't need them anymore. Power still has to be sent to your house.

[deepsinK]

I understand both, but it's not like power distribution is a bottleneck for developing and implementing this stuff. Besides the fact we can make houses that aren't dependent on the grid already... which is very possible with mass market green home (efficient) designs (see also Solar Decathalon), newer flexible solar film tech (my friend works at the new facility that just opened up in Austin), and other emerging technologies.

[kuorakuora]

While I am an electrical engineering student, I'm not really qualified to answer about what you brought up. It is good to be self sustainable yes, I'd just have to wonder if complete decentralization of power is a good idea. It just seems like a waste to have a nuclear power plant powering one large building for instance.

The problem with green homes is that they aren't generally cost competitive at this point. In time that should change.

[unusedsn]

In that case they should have atleast mentioned him!

[kuorakuora]

Take physics.

[unusedsn]

oh! I AM SORRY. but it doesnt take a physicist to see that 2Kw of electricity converted to magnatism is gonna cause problems. The earings will be pulled out of your ears and your computer will just break!!

[kuorakuora]

Could you tell me which household appliance requires 2kW's of power continuously?

Also, are you talking about Watts or Watt Hours?

[unusedsn]

I guess I was talking about ovens and kettles - anything with an induction heater( Just Watts) I was thinking of the worst case senario.

[kuorakuora]

So I did some calculations and 2k Watts is equal to 2kW-hour's. (This is 7.2 million joules per hour).

*Neat Fact* It's about equivalent to burning 445 calories/second.

I'd honestly have to know much more about magnetic resonance coupling to give you a definite answer, but... I'm pretty sure that the transmission (keyword) of power is done in hertz. Do you worry about radio waves?  You probably are not going to have to worry about this.

[TheJansme]

the girl at left is super hot! i love her, huh! and i love witricity =D

[SilasRD]

All this because of Nikola Tesla, thank you Tesla.

[GuroArtist]

@SilasRD 100 years ago :)

[antdude]

What about interferences? I always have issues with those with wireless.

[jamewoong]

can this cause problem to us such cancer or disease...? i guess it's yes

[SilasRD]

Yes, EMF can make you suffer from cancer.

EMF is also the number one cause of stress.

[jamewoong]

if so, then good invention, but who's going to to use this if it can cause cancer? i know that all wireless phone that has DCT 6.0 can cause tumour once it is expose for long time.

[SilasRD]

Lots of people don't know that electromagnetic fields are dangerous. They can't protect themselves from a danger they not are aware of.

[bwillwall]

electromagnetic fields arent dangerous

[kuorakuora]

Some can be.

[kuorakuora]

The electromagnetic fields associated with this technology are not dangerous.

[liinisx]

Wireless electricity was in fact discovered about 100 years ago by Nikola Tesla. He did also discover Power-Station that generates electricity from Magnetosphere.

[bwpbruce]

[largepint]

canser ;O

[huesao]

Hmm. Did I see a wire coming out of the square magnetic thing?

[duraiden]

Well yeah, obviously, you need power to turn the coil into an electromagnet.  If it was just a fixed magnet in the wall it wouldn't do anything.

[reuala]

i want the wireless girls

[CooPLooPs4twenty]

hmmm seems like it needs some more work... one coil per every 1-2sq feet seems kinda pricey, Ill keep my wires for a couple more years

[MiguelsChannel]

i don't care how much this is i want it now i'll spend 4grand on my living room alone

[AtrixAlpha]

cool
