You're missing a capacitor on the reciver coil, I use an air-variable capacitor for fine tuning on mine. Put the coil at the other end of your house then just using a frequency generator you can tune into the resonant frequency of that coil and watch the neon light up. Then measure your input and output to see if you'd picked up extra energy from your local environment.
I just finished building a transverse receiver today with a small coil and a long antenna connected to a 316s steel sphere.
wow you guys have no idea what you are talking about, "wireless transfer" has been here since the first transformer was invented, learn more from transformers so you know what i'm talking about. REAL wireless transfer should reach high distances and shouldn't involve coils, since coil "wireless transfer" has much energy loses, thats why is used in transformers
in 50 years they probably say "oh.. you were one of those guys who played around with electric field.. i am sorry your arm and legs fell off" .. it was the same with x-rays lol ; )
@BadWithNames123 X-Rays are high energy ionizing EM waves; These are radio waves in the very long range - A Kilowatt of it can flow through for a year and it won't cause a thing. Although at slightly higher frequencies (in GHz range) one has to be careful not to get exposed to higher power. If you are so afraid stop using yr cellphone and microwave they are a million times more risky.
Tesla did suggest wireless power but he was way ahead of time and his approaches were very different and would not have worked. What is being shows here is wireless transmission via induction between two coils that is loosely coupled (not very different from transformer). This technology existed for 100s of years but is not useful because of very low efficiency and range. But few years back researchers from MIT came up with the idea of using the same principles but strongly coupling the coils.
well duhhhh how do u think we get free tv from brodcasting towers or radio? just the difference is the power and consetration of the right frequencies
wireles energy is not good and it will never be used.becouse it emmits electromagnetic radiation just like your pc phone .... but radiation from this machine wireless energy is much stronger peace!!
@martyn347 radio and microwave IS electromagnetic radiation. both are very low frequency. im sure radio waves can be dangerous, but no offence, im not too sure you understand everything youre talking about.
maby this sounds stupid.. but if you make a very very big one and integrate it to the walls of your home, you would get a strong magnetic field so that you can have electricity all around your home :D.. (its a bit expensive.. but then you have true wireless energy)!

Actually you can get energy from an AM radio signal. If you get close enough to a transmitting antenna with a florescent bulb it will light. Also if you are in a fairly strong signal aria you can light up an l.e.d. with a crystal set that's connected to a good antenna and ground.
@egn83b any coil will work regardless of its resonance. This is essentially the same thing that happens in a transformer of any kind, those directly outside the power plant and those that are on cell phone chargers and laptops. There is no physical, metal connection between them, the coils transmit energy due to their fluctuating magnetic fields.
@easymac79 True but their is more going on to it then just magnetic fields. You also have to resonance or a correct alignment or the effect does not work well to power anything useful. The only thing I know is that Tesla is the best resource to understanding this technology.
@egn83b Tesla was a very brilliant man, but has very little to do with the concept of electromagnetism. The only thing resonance has to do with this is if the primary coil's frequency is within the range of the secondary's. This is easily obtained by using copper in both sections due to its wide range. Alignment is only important for efficiency, as the video showed, far away loses efficiency.
@bclinto83 Well how do you build? Check out the overunity form for that question because the answer lies within the online community posting schmatics. Theirs no wrong way or right way you just have find a circuit you like and experiment. This isn't best buy, its DIY investigation or reasearch. Well as for how much power has to do with circuit design that powers the coil. I mean you really need to investigate the SEC 15-3 videos or the jouel thief videos here on youtube & also tesla patents
@egn83b resonance has nothing to do with electromagnetism. This is basically a transformer that creates a magnetic field on one coil and the other coil picks it up. The Maxwell-Faraday equation explains this simply.
we are trying to do the same thing, but it does not work, can you please tell what material you exactly used and what techniques I have to know to make this work. IT IS VERY URGENT..
this guy is thinking of how to make money off of this idea. just like the power mat. ive been thinking too and so far have seen a video of a device that charges your hybrid car when parked in the garage in the right position with the gps monitor in the dashboard telling you to move forward or backward. pretty cool :)
@meistverkauft no loss lol thats impossible. you are foolish. that breaks the law of concervation of energy and the inverse square law that is seen in coulmbs law describing the electric field. Im currently building a tesla coil and it is not that efficent at all. actually other than looking cool and creating high voltage its quite impractical.
@ubrbzkr It's not actually inverse square law here because it's near field (less than 1/4 wavelength), so you can get up to about 90% efficiency. Most Tesla coils themselves use the magnetic coupling trick and manage about 85% efficiency with a coupling coefficient of about 0.2ish. The trick is all in the resonance.
I have seen the flat tesla coil transmit power over 300 feet from a signal generator with no loss; powering a model electric motor boat. Retuning was required with distance changes.
This is how transportation will occur eventually. In 2005, it was made clear that an EMF could power an electric engine without recharge due to its dynamic. Focus that direction and you'll change the world. Marinate on that.
just look up my tesla wireless research i put up, i have already shown that wireless is possible at a distance! its so important, my work proves teslas wireless energy system. everyone please look this up, the most efficient way of doing world wireless energy is the way i am doing it, you excite the earth into a conducting wire and staionary waves set up to give everyone on earth power! please click you will be amazed!
It will radiate a bit, but only one one narrow frequency, and the power that it radiates will be about the same as the power transferred (less radiation if the receiver is close to the coil.)
So if you're sending 1W at 50% efficiency, you;ll probably get about 0.5W radiated.
If you're sending 1W over a short distance at 90% efficiency, then you'll probably get about 0.05W radiated.
The radiation comes out of the losses, but the main loss is heat in the coil.
@moonlithanyou Actually the goal is to construct these wireless power transmitters in a way that utilizes the magnetic field for energy transfer not the electric feild like with radio waves. because of this that there is minimal EM interference and so that it has little if any affect on biological organisms since they dont really respond to magnetic feilds unlike with electric fields.
two EMF's, very cool stuff to play with. The electron charge swap is occuring in proximity dead zone at that distance due to coil wrap. Try a circle with packets next to each other with 200 wrap per packet. Keep the thirst for answers!
Thats why J.P Morgan stopped funding him when he found out waht Wardencliffe Tower was really for. He had been told that it was a communications tower, but Tesla intended to use it for Electrical energy transfer without wires. His range was 15 miles reportedly and was able to light up a field full of phosphorescent bulbs with it
This is exactly what Tesla did in the early part of last century, although this is a modern adaptation. Look up "The Wardencliffe Tower", demolished in the 40's. Tesla, funded by J.P Morgan an illuminati bank wanted to transmit free electricity via the ionosphere, See the experiement "Field of Lightbulbs" in the film "The Prestige", which was actually conducted, where he lit a field full of lamps from 15 miles away. J.P Morgan was not amused and withdrew funding,
I tried this out with 555 astable circuit producing about 150 KHz, 12V but no result. Why do u connect the capacitor to the coil? Help? What is the voltage applied to the primary coil? will this work even if the coils are in different sizes?
it could work if the coils are in differnt diameters but you will have to connect an especific capacitor to each coil. You have to create the resonance to make the most perfect energy transmision. can you teach me how to use a 555 to get a lot of frecuency please?
Thats because hte coil is putting too greater load on the 555 astable which can only sin or source 100ma at most. You need a buffer transistor on the output (pin 3) and a diode across pin 3 and ground (forward biased cathode to ground). Then you will get an output you might also want to put a resistor in the collector lead too - good luck
if you wanna calcule the inductance of the coil you can use this formula L=u.Nsquare.Superfice/lenght. But thisis for longer coils. for a shorter coil you need to do it practicaly
What concerns me with this technology is what happens if you have an accidental antenna when these devices are powered on. Would the non-electrical wiring in your house pick up the right frequency and create a fire hazard by making a short circuit?
@zimtower , Not an expert on electrical engineering, Would it be possible to assign an IP address or some sort of identifying number ie HEX numbering system to your electrical appliances , this number would tell the server ie the electrical source how much electric output should be giving to the electrical client.
Yeah you could but using RFID tags would be a much simpler and cheaper way of doing this. I belive that the company that makes the PowerPad (or PowerMat?) uses RFID tags to identify the devices it is charging.
basicaly this is the same thing that book stores, video game stores and places like that put in there devices for security reasons and for inventory control. it's what the metal detector looking tings at the store exits are for, they detect, activate, and read the rfid tags that pass through them.
unless your stainless steel kitchen side is resonating electrically with the antenna no. what worries me is what happens when theres a lightning storm and oh dear +1000000 volts to your circuit all of a sudden O_o boom.
@zimtower This was my concern as well, but they make these things for real for devices such as cameras and phones. I would think all the components in there would pick up stray energy, but they dont. It must not do much if its not a full coil to pick up a large amount. And if you are building a coil inside your wall and placing an electromagnet nearby, you obviously are going to be aware of whats going on.
@zimtower Induction heaters rely on the exact argument i just disproved, a phenomenon called 'eddy currents' is created, basically, the seamingly inert object acts as a secondary coil and will pick up the energy at a ratio of 1:[# turns in primary] which can cause a short circuit and be very dangerous. These devices are in actual use and dont pose a problem so i am not concerned about eddy currents developing.
@zimtower No. Tesla died in Room No. 3327. His white gloves tell you brethren. His clues tell me. Tesla is the thirty third degree. The message to you is this... Harriman told Merriman to set that stage. John Muir's glacier would feel the rage... Man made earthquakes for 111 years.
English Association Record No. 333 was on September 3 at 3:03 p.m.
Wireless energy was all but free.
But they did away with Shide Nos. & sold you gas.
The 33rd degree is TESLA. Earthquake Milne Shide No. 333
@godulous Tesla made earthquakes in 1899. That is why he didn't receive the Nobel... his WMD is historic just look at the hotel. Room #3327- #3328. 3h3m27s - 3h3m28s The first WMD was delivered from Knob Hill, Colorado Springs to Yakutat Bay you see.
@insightllc The Reason that Tesla didnt win the Nobel Price was not because he Made EarthQuakes.....!!!? The fact that there are 14 people here that has given to this statement toms up is amasing. People should research some more before they accept anything.....!!!?
@Grundalizer Not to mention the poor fish in Alaska, September 1899. THIS FROM USGS The earthquakes lasted 27 days—September 3 to 29, 1899—and included four or five world-shaking disturbances and hundreds of minor shocks. During four weeks there was almost constant palpitation of this part of the earth's crust. The shocks were most severe on September 3, 10, and 23, and were great on the 15th, 17th, 26th, and 29th. On the 10th there were over 50 small shocks and two world-shaking disturbances.
@jayjangles well... he beat nature... historically... 47 ft. uplift at sea level plus chasms ...Tesla made earthquake No. 333 on September 3 at 3:03 p.m. epicenter time in Alaska 1899. So saith the lord your god. -Biblical Prophet
@quantumbits Nikola Tesla Room #3327 because Earthquake Machine No. 3 was the Knob Hill Apparatus in Colorado Springs which caused the 27 day long 1899 Alaskan Earthquakes commencing on September 3, 1899 at 3h03m27s or 3:03:27 pm epicenter time. That was a year divisible by 3 times 3, a month divisible by 3 times 3, a day divisible by 3, in an hour divisible by 3, a minute divisible by 3, a second divisible by 3 times 3 times 3 Earthquake Milne Shide No. 333 and lasted 3 times 3 times 3 days
@insightllc Wow that's a lot of 3's. You know if you take 12345679 x8 on a calculator it equals 98765432. What physical evidence indicated that he caused the quake?
@quantumbits Tesla had some... issues. and one thing is that he LOVED the number 3. And he wrote in his journal that he caused his entire building to shake by means of an air spring hammer that he placed on an I beam of his building, not realizing that he could have done. I have heard no proof of an earthquake itself though. *shrugs* for all we know he actually did cause one though.
I think this is why resonant circuit are so useful.
When these type of systems becomes more and more common, certain standards has to be made so that there is little interference or out-of-bandwidth transmission.
As these can have very high frequencies, it should be possible to exclude most other receivers and circuits. Also, at hf, high voltage and low current you do not necessarily get so much heat when something is shorted.
@zimtower Unlikely. The reciever has to be a coil to get the electricity so it is not like just any old antenna will pick it up. Also even if there was a coil reciever in your house that you where unaware of it would have to be close to the transmitter to recieve an adequate amount of power to start a fire. On top of that it would have to be facing a direction which allows it to pick up an adequate amount of power aswell.
it's like a transfo, primairy and secundairy coil, He uses a function generator, it doesn't matter if its AC or DC, you got to have an alternating current, but not like AC. It wouldn't work on a battery, unless you put between some fancy electronics...
And about that 60W bulb, well there it's probably much higher voltage then 3 volts... :p It's a very nice experiment though ^^ nice vid ;-)
well its a coil right? I don't know if this is AC power you are using or DC if its DC than there is a flow and the magnetic field is going in a direction, and it is probably going in the same direction you have it at the best connection, most likely why your loosing power at 1 foot above the primary
So, If you were to make two large coils like the ones you have here made of, say, copper wire, and have one coil connected to a AA battery or something, would it work? ( In Other words, made of materials likely to be found around the house)
It is. Google "power lines cause cancer". Those large power lines generate the same field. You can show this by taking a large fluorescent light bulb and stand right under one of those lines. It will light up.
As the result you have some light worth of 0.001 lumen on some distance. You could have used all that wasted energy for lighting a bulb, and results would be much more efficient, really.
I don't understand how this works, isn't the voltage jumping into objects and persons that is in between the sender and the receiver, being that it's in low voltage it doesn't do any harm? or the kilowatts are being sent on a very high frequency that doesn't effect people? why does this work?
Do some quick reading on Mutual Inductance. It's a simple principle with some complex math behind it. If you're math savvy read about Maxwell's Laws of Electric and Magnetic fields. I hope this helps.
I liked it. I'm actually considering doing something with wireless power transfer for my senior project next year. I'd like to link the lights on hitched trailer to the truck towing it by EMF waves. It would eliminate the wire hassle, and prevent corrosion on the wires. Got any pointers?
Isn't this just magnetic inductance? My electric tooth brush charges in the same manner. Nice little lab though.
You can argue that electric and magnetic fields don't exist since you can do all of classical EM using an action at a distance formalism. Or at least Griffiths Introduction to Electrodynamics says you can.
I think saying the vacuum is a medium is very misleading, do electron wave forms have a medium then or is it pure mathematical formalism? Most argue the later.
this is a specialized form of magnetic inductance that uses resonant frequency. That's why he's using the function generator. Using the resonant frequency like this increases the efficiency since the power is only picked up by the other coil which resonates at the frequency that the first coil is working at.
Since this is just an emf wave, a medium is not required to travel. It's based on the same principle of the land rover that was on mars. how do you think it sent data back to NASA? There was nothing between mars and the earth! just empty space!
here's how it works.
The rover produced a frequency wave and traveled through space (where there is nothing to carry a wave through, hence no need for a mechanical wave)and was receptive by whatever receiver technology NASA used.
this is just an em field around the coil, the reason he moves it around is that the 2ndary coil cant amp the field to light the led, moves it closer or on top boom. remember what those ferrite mag pictures look like its the "same thing"

@moonlithanyou Actually the goal is to construct these wireless power transmitters in a way that utilizes the magnetic field for energy transfer not the electric feild like with radio waves. because of this that there is minimal EM interference and so that it has little if any affect on biological organisms since they dont really respond to magnetic feilds unlike with electric fields.

two EMF's, very cool stuff to play with. The electron charge swap is occuring in proximity dead zone at that distance due to coil wrap. Try a circle with packets next to each other with 200 wrap per packet. Keep the thirst for answers!

How much power are you putting in? Are you using external PSU or directly from function generator?
What voltage is that LED?

This is where J.P Morgan's famous saying comes from "If we give everyone free electricity, where do we put the meter".
Heoriginally thought wrongly that Wardencliffe tower was going to be some sort of communications tower.

The Illuminati did not like Tesla, particularly because he was attempting to do this for the good of all.
Tdog283 2 years ago
Thats why J.P Morgan stopped funding him when he found out waht Wardencliffe Tower was really for. He had been told that it was a communications tower, but Tesla intended to use it for Electrical energy transfer without wires. His range was 15 miles reportedly and was able to light up a field full of phosphorescent bulbs with it
computersolutions164 2 years ago
This is exactly what Tesla did in the early part of last century, although this is a modern adaptation. Look up "The Wardencliffe Tower", demolished in the 40's. Tesla, funded by J.P Morgan an illuminati bank wanted to transmit free electricity via the ionosphere, See the experiement "Field of Lightbulbs" in the film "The Prestige", which was actually conducted, where he lit a field full of lamps from 15 miles away. J.P Morgan was not amused and withdrew funding,

I tried this out with 555 astable circuit producing about 150 KHz, 12V but no result. Why do u connect the capacitor to the coil? Help? What is the voltage applied to the primary coil? will this work even if the coils are in different sizes?

nick14kn 2 years ago
it could work if the coils are in differnt diameters but you will have to connect an especific capacitor to each coil. You have to create the resonance to make the most perfect energy transmision. can you teach me how to use a 555 to get a lot of frecuency please?
lapulga5 2 years ago
Thats because hte coil is putting too greater load on the 555 astable which can only sin or source 100ma at most. You need a buffer transistor on the output (pin 3) and a diode across pin 3 and ground (forward biased cathode to ground). Then you will get an output you might also want to put a resistor in the collector lead too - good luck

if you wanna calcule the inductance of the coil you can use this formula L=u.Nsquare.Superfice/lenght. But thisis for longer coils. for a shorter coil you need to do it practicaly

What concerns me with this technology is what happens if you have an accidental antenna when these devices are powered on. Would the non-electrical wiring in your house pick up the right frequency and create a fire hazard by making a short circuit?

@zimtower , Not an expert on electrical engineering, Would it be possible to assign an IP address or some sort of identifying number ie HEX numbering system to your electrical appliances , this number would tell the server ie the electrical source how much electric output should be giving to the electrical client.

Yeah you could but using RFID tags would be a much simpler and cheaper way of doing this. I belive that the company that makes the PowerPad (or PowerMat?) uses RFID tags to identify the devices it is charging.

@zimtower It is almost impossible for a random antenna to be set at the same exact frequency of the magnetic field.
jerrui1 1 year ago
@zimtower This was my concern as well, but they make these things for real for devices such as cameras and phones. I would think all the components in there would pick up stray energy, but they dont. It must not do much if its not a full coil to pick up a large amount. And if you are building a coil inside your wall and placing an electromagnet nearby, you obviously are going to be aware of whats going on.
easymac79 1 year ago
@zimtower Induction heaters rely on the exact argument i just disproved, a phenomenon called 'eddy currents' is created, basically, the seamingly inert object acts as a secondary coil and will pick up the energy at a ratio of 1:[# turns in primary] which can cause a short circuit and be very dangerous. These devices are in actual use and dont pose a problem so i am not concerned about eddy currents developing.

@Grundalizer Not to mention the poor fish in Alaska, September 1899. THIS FROM USGS The earthquakes lasted 27 days—September 3 to 29, 1899—and included four or five world-shaking disturbances and hundreds of minor shocks. During four weeks there was almost constant palpitation of this part of the earth's crust. The shocks were most severe on September 3, 10, and 23, and were great on the 15th, 17th, 26th, and 29th. On the 10th there were over 50 small shocks and two world-shaking disturbances.

@quantumbits Tesla had some... issues. and one thing is that he LOVED the number 3. And he wrote in his journal that he caused his entire building to shake by means of an air spring hammer that he placed on an I beam of his building, not realizing that he could have done. I have heard no proof of an earthquake itself though. *shrugs* for all we know he actually did cause one though.
EPhantom125 8 months ago
@zimtower
I think this is why resonant circuit are so useful.
When these type of systems becomes more and more common, certain standards has to be made so that there is little interference or out-of-bandwidth transmission.
As these can have very high frequencies, it should be possible to exclude most other receivers and circuits. Also, at hf, high voltage and low current you do not necessarily get so much heat when something is shorted.

derickhaywood 1 year ago
@zimtower Unlikely. The reciever has to be a coil to get the electricity so it is not like just any old antenna will pick it up. Also even if there was a coil reciever in your house that you where unaware of it would have to be close to the transmitter to recieve an adequate amount of power to start a fire. On top of that it would have to be facing a direction which allows it to pick up an adequate amount of power aswell.

Isn't this just magnetic inductance? My electric tooth brush charges in the same manner. Nice little lab though.
You can argue that electric and magnetic fields don't exist since you can do all of classical EM using an action at a distance formalism. Or at least Griffiths Introduction to Electrodynamics says you can.
I think saying the vacuum is a medium is very misleading, do electron wave forms have a medium then or is it pure mathematical formalism? Most argue the later.
ko1n 3 years ago
this is a specialized form of magnetic inductance that uses resonant frequency. That's why he's using the function generator. Using the resonant frequency like this increases the efficiency since the power is only picked up by the other coil which resonates at the frequency that the first coil is working at.

Since this is just an emf wave, a medium is not required to travel. It's based on the same principle of the land rover that was on mars. how do you think it sent data back to NASA? There was nothing between mars and the earth! just empty space!
here's how it works.
The rover produced a frequency wave and traveled through space (where there is nothing to carry a wave through, hence no need for a mechanical wave)and was receptive by whatever receiver technology NASA used.
hope that helps a bit.
