Wireless power transmission using Tesla coils

[TheZEOKEY]

cool,. that's really wireless

[1BrknHrtdRomeo]

look Ma! no wires! =D

[ABC1232622]

who knows were the fuck I can get those little wires that look like many jumper cables

[timongarretson]

@ABC1232622 Alligator clips? They can be found at Radio Shack, and many places online.

[ChemicalMikeUK]

@ABC1232622 If radio shack doesn't have them you might want to try the local head shop.Ask for roach clips! ;)

[BlackGoldEstates]

wow you have invented the transformer

[highvoltagefeathers]

@BlackGoldEstates a tesla coil obeys practically none of the laws that a transformer does. Transformers aren't wireless, smartass.

Its a cool project, quit hating.

[io504]

@highvoltagefeathers Air cored transformers are though. A Telsa Coil is a form of transformer.

[highvoltagefeathers]

@io504 It is an air core resonant transformer. Basically, it is a big RF transmitter and receiver, and does not follow the laws of typical transformers.

[io504]

@highvoltagefeathers It follows the rules of air - cored transformers. Also from Wikipedia: A Tesla coil is a type of resonant transformer circuit invented by Nikola Tesla around 1891.[1] It is used to produce high voltage, low current, high frequency alternating current electricity.

[datsun1973z]

could you send a frequency to the other coil like a solid state musical tesla coil?

[MACHINEIRON]

An energized coil close to another will induce in the second coil a voltage. It's all normal.

Those Tesla coils are nicely made. How did you wind the copper tubing in to such a neat coil?

[luckyladybag]

What happens if the distance of separation increases?

[akash41415]

Can anyone tell the apparatus required in this video. PLEASE !!!

its very important because i am doing a project on wireless power transmission

thank you :)

[firebomber39]

@akash41415 Ummm... Tesla Coils? you should know that if you're studying wireless power transmission.

[theidealmuslimful]

what is the need of battery there i dont understand can some1 help?

[ncranfill]

A true Tesla coil transmits energy without dissipation. RF dissipates and can be blocked by Faraday cage, while true Tesla coils Can't be blocked. nice though, 1 step closer to true wireless power.

[Teslaniko369]

You are missing one more important thing my friend !!! that's why when you move the second coil away the light dims

[freemanx2x]

@Teslaniko369  and that would be...?

[jdflyback]

man I can't imagine how tesla did this with the coils miles away from each other.

[gekiryudojo]

Nice!

[marktagum2008]

it will also work without the cylindrical thing wit a winding... transformer basic lol

[AlienRelics]

@marktagum2008 Try it, it will not work. It requires the resonant coils.

You could also do this without the tall coils ONLY if you tuned the large copper coils to the same frequency. But without resonance, transformer action without an iron or ferrite core will not travel very far at all.

I've done smaller scale experiments myself.

[JustSomePerson888]

isn't that just the same as how transformers work, given the 2 different windings don't actually touch.

[perforators]

Man vienmēr patikuši šie eksperimenti :)

[mpccenturion]

Thank you! I guess that the brightness of the reciever bulb, varies due to the standing wave being - "in phase or out" as the distance increases and decreases.

Does it also mean that it would brighten when another harmonic distance is intercepted, as you increase distance from the wireless power tower?

[nRADRUS]

what's about efficient ? :)

[kunadude]

You will tune past many harmonics. One of these being the highest will be the frequency desired, which lie above what was expected as your resonance.

[kunadude]

In an ideal application such as an Erected Tesla transmitter located at a power plant, would be tuned to a reciver located at a nearby city for example. Miles away. Power is easily communicated at virtually zero loss wirelessly. However, as the two systems change in distance, they need to be re tuned. Such as mobile.

[kunadude]

The Tesla Coil Transmitter & Reciever is Dynamic. Many builders only take into account the capacity of their top load and coil in their calculations for resonance.

This is merely a starting point. You need to understand that the space between

the two toploads is part of your capacitor now and does change with distance.

So, the over all capacity of the system changes with separation distance and

requires retunning if you wish to increase the distance they can communicate.

[kunadude]

The resonance frequency one is dialing for is always above the frequency which most

Tesla Coil Builders typically dial in their sytems too. Which is based on standard calculation of LC resonance of the coil and its capacity. This is only a starting point and

is only the EM part your seeing. The LM wave freq lies above this. Its easy to find

with a scope. Simply keep increasing your freq until the max pk is detected. You

will find a pk above what you thought was your Resoant Freq.

[kunadude]

As you change the distance between the transmitter & reciever, you need readjust your

frequency, as it will have changed. Otherwise you will witness a drop in power transfer

and decrease in the transmitted range. I have tested this myself and found this too be the case.Therefore any Tesla Builder that does not understand this simply believes it

only works close range as how its always been demonstrated in prior art.

[DeadJack57]

You need to earth common the bottom ends of your secondaries. Range will be unlimited.

[liuxiaod2000]

I have a new idea about wireless power. I find that wireless power can make energy in the air. You can find my paper as "Energy Multiplier in Retarded Resonance".

[jatigre1]

I guess no explanations here are required, right?

[kokotele2]

[AdomHussein69]

Is it AC or DC? I'm also curious about what kind of component you used as a switch.

[m3sca1]

it is interesting that the drop off in power with distance is so much-have you gone further across the room to see if there is nodal points ?

perhaps they need to be grounded

[Jetijs]

@m3sca1

Using one wire transmission I can light that bulb up at 10 meters or further away, just a little tuning is needed and all that energy goes through just one wire. If everything is tuner right, almost 100% energy transfer can be achieved. The thing without wires imho works as combination of simple magnetic induction from the primary coil of the first setup and the high frequency currents induced into the receiving coil. There are no more nodal points using the wireless setup.

[Jetijs]

To achieve this effect both coils need to be equal, wire length, inductance and resistance. It is like tuning forks, if they are close to each other, then striking one will induce vibrations in the other if it resonates at the same frequency. Just putting your hand near either of the coils can change their capacitance enough so that the resonance frequency of the coils doesn't match anymore and the light goes out.

[Jetijs]

Also, I tried many setups with ground wire and even with a large capacity instead of ground and both together as two ground system. So far it is my impression that the setup creates a standing wave and if one wire transmission is used, then you have to put our receiver coil in the point where standing wave appears, if long wire is used to connect both coils, then the receiver coil can get outside the standing wave and the bulb will be dimm or not light up at all. Some extra capacity solves this

[Jetijs]

@Jetijs

Also I forgot to mention, resonance in the first coil is of course needed, else it wont work.

[ashtweth]

Its always a privilege for us to watch you work man, ill admit that any day

[Jetijs]

@ashtweth

Thanks man :D

[prankmypants]

Hi have you ever experimented with bedini devices and motionless energy generators? i see alot of wild claims online but no one seems to be able to show anything credible. you on the otherhand seem to have your head screwed on and if you had done some work on it then it would be worth another look. :)

[Jetijs]

@prankmypants Yes, in fact I have built several Bedini SSG wheels, tried some self runner concepts and made some self oscillators. I have never seen OU in any of these devices, in my opinion they are good battery chargers and defulfators, but nothing more. At least judging from the info out there. Could be that there is a piece missing that makes all of these devices work in OU mode, but as long as I don't have that info, they all are just battery chargers.

[prankmypants]

@Jetijs

thanks yeah as i thought. when you say self oscillators do you mean the motionless energy generator like the one proposed by tom beardon?

[Jetijs]

@prankmypants

I know only of one device proposed by Bearden and it is called MEG. It works on different principle than Bedini stuff. The Bedini self oscillators I have built work simply by taking current from a source battery, magnetizing the coil core, then the impulse is stopped and magnetic field collapses and this induces a new current of high potential called the inductive spike or radiant spike. This is then fed into the charging battery, just like in SSG setups. SSG without moving parts

[prankmypants]

@Jetijs interesting. sometimes i wonder about all the energy that is just out there in the form of radio/microwave etc across all bands and wonder what sort of output could be generated if you could just build a full range antenna somehow. even if it was simply 0.1w it would still be a useable amount. i was reading that intel should have 4nm cpus by 2022 and the required power is getting so small we could use this kinda tech to produce self powered watch/armband computer systems.

[catfishagain]

nice dude :) polished as ever

[min2oly]

Very nice demo!

thanks for sharing.

[universalmoor]

gotta love TESLA! gOOD WORK!
