I loved doing this experiment. Tuning into a resonant frequency, like using a crystal radio, can increase the power. Also, the higher the antenna is into the sky, the greater the potential. Especially if you also use earth ground... just like a crystal radio. Keep up the great work my friend.
It's true. Richard Feynman won a nobel prize for that if I'm not mistaken. But for sure he discovered it and wrote a book about it. Check out rimstarorg videos on powering a corona motor with atmospheric electricity.
Bigger capactors may have a larger power-up time, but then can sustain a load longer. So you can change that. Plus a direct short to light the LED of course drains the LED fast. But if you were to use the Joule Thief circuit, you could permenantly light the LED with very little power. Its really an oscillator, and the LED is lit using high high-frequency voltage spikes, but the eyes sees the LED as bright, even though its pulsing (off/on/off/on).

It might be enough power to run MOS logic and a liquid crystal display, like a simple clock. I'd like to see it with a fractal antenna too. It is a way to evaluate antennae.
Thanks for the video. It was quite helpful. A couple of things that would help are a longer, insulated antenna (not grounded), have the antenna in an open area. Also, if I'm not mistaken, a ground wire from between the electrolytic caps would help.
A large antenna like a 100 foot long wire antenna will bring in usable current. Not a lot but enough to charge a small battery. If you live near high voltage power lines you can get power but stay off rights of ways because they belong to the power companies and we don't want to steal power. It's ok to harvest leaked electricity that's on your own property but never on rights of ways. 73
@@ronb6182 - Thanks again. I was wondering about using 5 x 20 foot long antennas for the same (or very similar) result as 1 x 100 foot wire.

Aluminum foil wrapped around a tube with each layer insulated from the others by appropriately sized waxed paper as an antenna. Hmmm.

+Alexian Dorias . can't remember sorry. I did this experiment over 18months ago. I used the supercap to run a joule thief circuit driving the led. Lol maybe i should have written it down my results somewhere.
Which all diodes did you use? I mean at 00:23 ,you told you used 1N34, OA70, 1N4148 but you used 4 diodes in the circuit? So which one is the fourth diode?
A very nice design. It works because I made a similar one, but with different parts and LEDs. The voltage was very low with the reverse current. Didy I used: BYV27-200 DIODE 2A 200V 25ns VISHAY the capacitor connected to the antenna is 2x Capacitor 0.22uF [TNS-2TH] 0.22uF / MKP the capacitors connected at the bottom are: 2x 100uF 8X12 50V electrolytic capacitor. This set worked best on a 2m high copper wire, gave a voltage on a 1.10 volt meter. It seems to me that if you change the diodes to even faster ones, for example Schottky diodes and find a module duplicated several times, and add a properly made Transformer, we would get quite good energy. Ludic Science and what parts did you use? Can you specify exactly?
I made this with 1n4148 diodes. It does not work well. I am reading around 0.25v after several minutes of charging, and the antenna (about 10 feet of magnet wire) seems to do nothing. Whether attached or unattached the capacitors charge at the same rate.
Very Nice, let me tell you a true story. Back in the 80's a guy built a transformer and circuitry and mounted on a tall pole, he then positioned it just below the standard power lines behind his house near the alley...... he was able to get substantial voltage and ran his house with it.... he got away with it for almost a year and then the power company took him to court and insisted he was stealing power ....he claimed ( and I agree ) that he was only turning the magnetic fields that were being emitted into free space into energy, he was utilizing wasted energy ..... unfortunately he lost the case ............ moral of the story ........... only run the pole at night so the power company doesn't see it .........
Alien Physics moral of the story - electricity IS free..Tesla intended it to be but u know what they did to him, right? We are being raped by the power companies for sure.
Wow, what's up with all the dots. Of course he was stealing from the power company. He's loading the power line ever so slightly, and it changes the impedance of that line accordingly. The energy is not free. For the power company, they need to set precedence with the incident. They don't want to have to argue with every smartass that comes up with this idea, to "fool the system"
The problem is that the energy recovered from the magnetic fields has no useful application because it is very small. But certainly the field produced under high voltage towers, that yes can supply much of a residence.I have done this test many years ago.
Perhaps if the wire (antenna) were coiled and placed in a vacuum tube, what would possible happen? And also increasing the number circuitry and antennas to up the voltage and capacitance... Worth looking into...
I actually really like the circuit. So... 2.5 volts off of a very small antenna is actually pretty good. Especially if you consider that the voltage drop across your full bridge rectifier is around 1 volt; this is actually pulling around 4 volts out of the air. If you really want to increase the efficiency of this circuit, take a straight wire connection after the AC caps, but before the rectifier, and connect it to earth ground (either the "Ground" wire in an electrical outlet or a cold water pipe in your home). That drastically increases the connection your antenna has with Earth ground and increases the current that you can harvest from literally every signal the antenna encounters. After that, you might try connecting a signal transformer between the earth connection and the circuit, but that starts to get into impedance matching and filtering.
Something interesting I saw on another channel: by using a cryal radio style tuner the other guy was able to find the best frequency and get higher efficiency, He got 125 mA at 4.8 V
Hey it's been awhile but I figured I'd write back again since I built my own version of the circuit and played with it a little bit. I was able to get about 10 milliwatts continuous on an LED however. I was measuring the output with an oscilloscope and noticed most of the power was coming from the wall. When I got away from the wall, the power dropped considerably.
Could you please explain what is the purpose of C1 and C2? The way I understand it is that alternating signals (that you also capture here) just pass through capacitors before they are rectified.
Please can someone tell me if a human could be used as a Compensator, referring to the 2 dark bits at the start of the antenna, if so I have a second question thank you
@consciousenergies could I use this antenna design and modifie it's and then use some of the techniques u spoke about with crystals and have it designed in a way I could connect myself to it or have a round base I could sit in the middle of, I suppose it would be a sort of oregon kind of thing, if you have any ideas I would be great full
Is it a cool experiment, yes, absolutely. Does it produce any significant amount of amperage, not that I have seen. However, what would happen if several of these circuits were run in parallel? Has anyone tried and/or documented this? Thanks for your videos!
Would a longer antenna or different antenna design cause any noticeable change in charging rate? If there is an increase in charging rate with a bigger antenna, it might be more useful.
This is the Joe Tate ambient power generator. The amount of power you get depends on how close the receiver is to the transmitter (inverse-square-law) and how much power the transmiter is using -- and the losses.
I see a good use for such low amount of energy. (for an example temperature sensors wich operates once a minute or 10 minutes) must use single charge to transmit data and go back to sleep. Btw what about scaling, 10 independent antennas =) or 100, 1000 would it absorb enough signal to make interference?
I have an inquiry. Hypothetically, say you modified your antenna to maximize electron harvest, and upgraded your capacitor sizes from electronic grade starter storage, and ending with either commercial grade 600+ volt capacitor, or homemade Leyden Jar modified for higher voltage storage, over longer duration of time, would this benefit the process?
Schematic in this video doesn't show GROUND connection. It should be on negative lead of output. Add the ground, and this Tate Ambient Power module does WAY better.
Another enhancement. Tesla was all about resonance. If you had atenna, then tuned circuit, then joe tate ambient power module, the tuned circuit could be used to tune to the strongest signal -- highest amplitidue. You could dial in a local radio station, or other signal that is strong. Just putting out a wire w/o a tuned circuit won't give a very large signal to the Tate module.
Resonance works by shorting out all frequencies except the wanted frequency. This makes the signal weaker than an untuned circuit that doesn't discriminate.
Oh my god, that is so cool! Yeah it's little energy but I'm sure it could power a low-power microcontroller to light up an LED for a few milliseconds every minute for example, and that is cool!
I built it as you described and the most voltage I was able to achieve was 29mV. I verified my circuit and tried many different antennas and grounding schemes. I was not able to achieve anything close to the 4V you stipulated.
O problema é que a energia recuperada dos campos magnéticos, não tem aplicação útil por ser muito pequena. mas com certeza o campo produzido em baixo de torres de alta tensão, essa sim pode abastecer grande parte de uma residencia.
Ok… so if you can essentially light a build from nothing at all excepting a single tiny little light build; why do we not string these together and charge a battery?
This technology is purposely kept secret and people who have tried to innovate in these areas have been killed. You would be a little bit more ''free'' if you didn't have to pay for electricity, they need you busy trying to survive so that you don't have time or energy to question. But fear not, very soon a change will come and we will have free energy. Have a nice day!
It's a small start, but can a rectifier be connected a a step up transformer designed to significantly increase its voltage output? Why is there a system design limitation in step up transformers today?
hello Ludic.... im impressed with your work here. can i ask you, what method did you used to build the electronic circuit on your "Energy harvesting: rectenna" project?? I am also doing some project here, same as you, rectenna... but, I'm a little lost now. I make RF energy harvest from 2,4 GHz. I choose "Dickson Multiplier" method for rectifier, but i didn't know what exactly the value of capacitance that i should pick for my prototype. Can I use your circuit design for my project to?? is it can possible work?? please give me some response, please...
I would like to see such a device but much scaled up, with power measurements and financial summary of the parts used. I think that multiple circuits could be arranged in a parallel connection to add their current.
May I ask, what are the values of your capacitors? Also, what about laying a single insulated wire beside (wrap it loosely around) a stretch of house wire that's constantly in use as an antenna?
Review Robert Murray-Smith's video on Rectennas from several days ago. Seems like we can get MUCH more efficiency from solar ether waves (aka radio waves aka em radiation) than current solar cells.
Neat! Very interesting, and a surprisingly simple circuit. This could be a fun circuit for students to learn about RF and capacitors. Perhaps it's even enough to power a small microcontroller (attiny, pic... idle 24µA, active 190µA, 1µA in sleep/watchdog mode) and either log data or blink briefly every few minutes. Could you post aprox. values of the capacitors and what diodes you used? Thanks :-)
Sorry, I watched it on a small smartphone (3") and missed that :-) Diodes-> Any of the types mentioned? Germanium type as they work best with low voltages (I used them in an AM circuit years ago, I think they'll conduct at around 0.3v already)
Question: Lets assume there is a source of electromagnetic wave and you made and put one of these collectors and collected power .. if now you put another one close to it will the power split between them or both of them will get the same power? i'm asking about conservation of energy
Combine with large area flat plate collector on a pole, like N Tesla suggested, and joulethief circuit and or any tech to improve capture and charge and you can improve it somewhat.
You should try this again but with 12, 6 in series and 6 in parallel Experiment with different heights, 6ft, 12ft, 24ft and on a busy street where there would be lots of signals
Having more than one will be a waste of money. If you put a bigger capacitor it will increase the energy stored there is no limit, but it will charge slower . But also a bigger antenna will make the capacitors charge faster.
Great video, i was thinking about doing this but at higher densities, RF units can be expressed in uW/m^2, so there is a lot of energy we fail to harvest with just one antenna, my idea is to create an array of antennas to draw as much of the energy as possible. Also optimizing the Antennas lengths to maximize reception and higher gains. What do you think about antenna design for optimizing energy gains?
build a wifi cage around your entire apartment so none of your signals get out and none of your neighbors' get in, simply harvest all of those spare waves for power
Dear Author Could you send scheme please. I didnt understand part of Diodes : 1N34, OA70 , 1N4148 ? Here 3 type of diodes did you used all of them for one scheme or you mean we can you 1N34 or OA70 or 1N4148? Thanks for attention.
You can burn a copper plate.Make sure not to clean it.Definitely,You should put wires..Connect the copper plate wire to the positive of diode and connect a wire to the negative of the other diode.Connect this wire to your steel roof....This will give you a regulated and clean voltage..
The question should be, "Can this be used as a power source for your Low power flasher?" It's all about the energy. The video shows the circuit is hardly lighting 3V LED (i=5mA), meaning 15mW maximum. It's very dim, so much less in reality. Unless you have a low power device that works with ~10mW, the answer is "no".
I just have question, if LED lights up from surrounding EMF / RF, dose it make weaker signal from WIFI? or Mobile Phone? Also I am wondering if it's possible to make the device which can suck those EMF radiation from mobile station?
Right, but look at how cheap the circuit is, would it be impossible to make thousands of these with little housings and maybe a printed circuit board and some decent batteries?
Try a lot of wires of different lengths all connected at the bottom. Another possibility might be like a multiband dipole antenna. At first not worrying about lengths, later there are frequency meters with spectrum analyzers ... could do the math to target wherever the peaks are for a given environment. Can anyone think of any reason any government has any reason to worry about harvesting any waste energy with all the energy concerns of our world's ever-growing population and strong push for green energy if they genuinely want energy efficiency unless it is all in actuality all about profit?
Hey man! I am doing this circuit as a capstone project for collecting energy from alternative sources. You seem knowledgeable about this stuff. Can you give me a tip on how can I increase the power of this circuit?
@@hossamabdelfattah424 Yeah hi. After watching your video I went looking for an antenna that could pick up multiple frequencies. The wire you have is fine being vertical, the thing is that this is about tuning/resonance and length is key so that particular length would be best at picking up a particular frequency (plus harmonics although more weakly). At first I was looking at multiwave oscillators but didn't understand them. Then multiband antennas like in ham radio. Turns out it's just a matter of having wires of different lengths basically. They are all soldered to the same place. This spot in a video shows some laid out on the floor being prepped: ruclips.net/video/8KHzsKYsZL0/видео.html Look up ... multiband dipole antenna ... for more. But ham radio frequencies are a lot lower than what you want to tune into perhaps if you might like to grab, say, wifi stuff. It's pretty close to a microwave oven. 5G is higher. Anyway, at this point it makes sense to switch over from thinking in terms of frequency and instead go with wavelength. Look up wavelength of wifi. There are two, 6 cm and 12 cm. Very short. Each leg of a dipole antenna (just means the connection is in the middle) is supposed to be 1/4 of the wavelength. So holy smokes we're talking about a wire that is half of 6 cm. At 3 cm total, and then you connect to it in the middle. I think that means the wire running to your circuit from the middle of these wires should be short, however you might be able to use coax for something longer. So anyway, just one wire at first as a test. 0:39 With the long wire removed for now, just solder a 3 cm wire in the middle of it to that point on the left, crosswise. Then try it close to your wifi router and well away from it. If there's a dramatic difference, then we're onto something. Other lengths can be added to that same point, some bending required I guess. Ideally you can eventually wind up with a bunch of different lengths tuned very well to the type of frequencies we tend to have in our environment. However 50 Hz or 60 Hz power lines would be altogether different, I can't comment on those. The spectrum analyzer I mentioned, that I bought recently, and am happy with so far, is a GQ EMF-390. Turned it on just now and seeing a peak at 2.43 GHz, that would be my wifi router and laptop talking to each other.
@@garyha2650 OMG, Master. Thanks a lot for your help; I will surely try this multiband dipole antenna. One last inquiry; as I told you I am having a capstone project about alternative sources of energy, and the required task from us is to generate or collect a noticeable amount of (power). So, even we got a sensible amount of voltage here but with a low amperage, I am not having a great power amount. So, any tip of how can I rise up the current? without changing the voltage?? Or can I use a Li-ion battery instead of the two electrolyte capacitors to store the energy??
@@hossamabdelfattah424 Nice to know its a school thing. Yeah we're limited by power however you might like the video called 'How a Joule Thief Works'. By the way, I never understood electricity until I started thinking of voltage NOT as EMF but as pressure, electrical pressure, electron crowding, not too much unlike air pressure, maybe that'll help some others too. I appreciate the kind words. Now I'm hesitating to answer in case I fall from master level lol, oh well, I have to be candid so: Maybe try a supercapacitor? I'm not sure if they have lower leakage. I think the main thing is just very high capacitance, thus might not help much here. You may want to look for any capacitor with the least tendency to leak across the dielectric, not sure. At this low of a voltage, there may not be much leakage to speak of. I would try something that might not work, the four diodes as a full wave bridge, the 3 cm wire at its middle soldered to where AC goes on one side of the bridge using short diode leads, the other AC to ground, and at first just try only that and touch the LED across the DC points of the full wave bridge. Then try adding one capacitor in parallel with where the LED will go. And then, if that works at all, what would happen with some more 3 cm wires added, maybe at angles to the first. Maybe some others of different lengths. And then maybe adding some of the elements in your diagram could improve it further from there. For the diodes, try Schottkey, maybe SB1040. I'm only saying that because I found out just hours ago from this: ruclips.net/video/kvWZjM1AcG4/видео.html Ok time to roll up your sleeves and try things, looking forward to learning what you find out. PS If this ultimately winds up being less than you would like, another possibility consistent with the capstone project theme that I also ran into today is 'Atmospheric Electricity Powering a Corona Motor/Electrostatic Motor'. He gets it working at 4 minutes into the video. No need for a drone, can use helium balloons to raise the wire. But up there, instead of wires with points, use a flat aluminum foil disk (maybe on light cardboard or glued straws or balsa to keep it flat) for lots of surface area. A point is great for *emitting* electrons, they all want to get away from each other and out into the air, but all trying to crowd in toward a point from the air they're not so onboard with that :)
@@garyha2650 What about charging a battery instead of storing in capacitors?? And It seems that in your opinion you think that harvesting RF won't be efficient in real life scale? meaning that I shift my idea to the atmosphere electricity? Will that produce a considerable amount if applied in real-life scale? --I am building a prototype that should be applied as a real-life project, so the power is the main concern--Thanks again Mr. Gary; I will be honored to document your name in the acknowledgement section of my poster.
Krisztián Szirtes Wrong, you simply sort out the different frequencies. Light has a much higher frequency than radio waves and so that is why they don't interfere. Sunlight actually has more energy due it it's intensity (higher amplitude)

@consciousenergies could I use this antenna design and modifie it's and then use some of the techniques u spoke about with crystals and have it designed in a way I could connect myself to it or have a round base I could sit in the middle of, I suppose it would be a sort of oregon kind of thing, if you have any ideas I would be great full
I'd suggest meditate on grass if you want to connect with nature @@nithinvasudev1590
is this enought to keep rtc clock from resetting when changing battery?
interesting!
Is it a cool experiment, yes, absolutely. Does it produce any significant amount of amperage, not that I have seen. However, what would happen if several of these circuits were run in parallel? Has anyone tried and/or documented this? Thanks for your videos!
current is very low. With several in parallel you do get more current, but still a few miliamps
@@ludicscience what about adding a battery?? Do yo now any paper?
Try using Joule thief circuit to light up the LED (don’t connect LED directly to your circuit).
What if i powered 433Mhz RF transmitter near the circuit will the voltage increase?
Very likely would
Would a longer antenna or different antenna design cause any noticeable change in charging rate? If there is an increase in charging rate with a bigger antenna, it might be more useful.
This is the Joe Tate ambient power generator. The amount of power you get depends on how close the receiver is to the transmitter (inverse-square-law) and how much power the transmiter is using -- and the losses.
Can the amount of output be increased if we will add a DC converter?
How much voltage can it produce?
How much wattage can it produce?
TY...
you can multiple it to 100 by using 100 antenna so you will have the output of 220V + 300W-600W-1200W
I see a good use for such low amount of energy. (for an example temperature sensors wich operates once a minute or 10 minutes) must use single charge to transmit data and go back to sleep. Btw what about scaling, 10 independent antennas =) or 100, 1000 would it absorb enough signal to make interference?
what is that component on the led "leg" and what is its purpose? Thanks for the great video!
I have an inquiry. Hypothetically, say you modified your antenna to maximize electron harvest, and upgraded your capacitor sizes from electronic grade starter storage, and ending with either commercial grade 600+ volt capacitor, or homemade Leyden Jar modified for higher voltage storage, over longer duration of time, would this benefit the process?
have you ever tried using germanium crystall diodes just curious how they would compare
i couldnt see exactly what you are using for this circuit
They are supposed to be germaniums
Schematic in this video doesn't show GROUND connection. It should be on negative lead of output. Add the ground, and this Tate Ambient Power module does WAY better.
Another enhancement. Tesla was all about resonance. If you had atenna, then tuned circuit, then joe tate ambient power module, the tuned circuit could be used to tune to the strongest signal -- highest amplitidue. You could dial in a local radio station, or other signal that is strong. Just putting out a wire w/o a tuned circuit won't give a very large signal to the Tate module.
Resonance works by shorting out all frequencies except the wanted frequency. This makes the signal weaker than an untuned circuit that doesn't discriminate.
Oh my god, that is so cool! Yeah it's little energy but I'm sure it could power a low-power microcontroller to light up an LED for a few milliseconds every minute for example, and that is cool!
I built it as you described and the most voltage I was able to achieve was 29mV. I verified my circuit and tried many different antennas and grounding schemes. I was not able to achieve anything close to the 4V you stipulated.
Hello, can i ask for the schematic diagram of how your diodes are positioned? Thanks a lot.
Made the circuit. Not grabbing a single volt!
could this be one of those old cellphone stickers that blink when you get a message/call?
such a 'kit' you can buy on Ebay to solder yourself but they only use the GSM frequency at around 900 MHz
Can i use 100nj 650v capacitor
O problema é que a energia recuperada dos campos magnéticos, não tem aplicação útil por ser muito pequena. mas com certeza o campo produzido em baixo de torres de alta tensão, essa sim pode abastecer grande parte de uma residencia.
Eu já fiz esse teste a muitos anos atras.
Connect the circuit to a voltage amplifier, and then to chargeable batteries. Then get the antenna as high as you can.
Ok… so if you can essentially light a build from nothing at all excepting a single tiny little light build; why do we not string these together and charge a battery?
This technology is purposely kept secret and people who have tried to innovate in these areas have been killed. You would be a little bit more ''free'' if you didn't have to pay for electricity, they need you busy trying to survive so that you don't have time or energy to question. But fear not, very soon a change will come and we will have free energy. Have a nice day!
What purpose do the red capacitors have?
and why to you need two electrolytcapacitors instead of 1 next to the rectifier?
It's a small start, but can a rectifier be connected a a step up transformer designed to significantly increase its voltage output? Why is there a system design limitation in step up transformers today?
Hello It would be nice if it was possible to build a blinking led powered by those radio waves
it is in fact possible!
hello Ludic.... im impressed with your work here. can i ask you, what method did you used to build the electronic circuit on your "Energy harvesting: rectenna" project?? I am also doing some project here, same as you, rectenna... but, I'm a little lost now. I make RF energy harvest from 2,4 GHz. I choose "Dickson Multiplier" method for rectifier, but i didn't know what exactly the value of capacitance that i should pick for my prototype. Can I use your circuit design for my project to?? is it can possible work?? please give me some response, please...
Have you got idea for that rectenna bro i.e rectenna
muy buen video me encanta la manera en la que haces la recoleccion de energia
re u using zener diodes or pn junction diodes
I would like to see such a device but much scaled up, with power measurements and financial summary of the parts used.
I think that multiple circuits could be arranged in a parallel connection to add their current.
this design does work I found it back in the early nineties in a magazine called Popular Electronics I made my own and posted a vid
YEAR OF THE ROOSTER I also made my own and made a video.
@@stonecold7945 ......did yours worked?
skhumbuzo cele yes
But mine worked
May I ask, what are the values of your capacitors?
Also, what about laying a single insulated wire beside (wrap it loosely around) a stretch of house wire that's constantly in use as an antenna?
Or you could use multiple wire antennas? For example, 50x of those?
very good and clear experiment
Could you theoretically make a bunch of these, stack them, and power the light longer? Would you need another antenna ?
Review Robert Murray-Smith's video on Rectennas from several days ago. Seems like we can get MUCH more efficiency from solar ether waves (aka radio waves aka em radiation) than current solar cells.
The description of C1,c2 and c3,c4 is mixed up at around 0:15, isn't it?
Sir, how can we improve it by doing some modification in antenna ?
Neat!
Very interesting, and a surprisingly simple circuit.
This could be a fun circuit for students to learn about RF and capacitors.
Perhaps it's even enough to power a small microcontroller (attiny, pic... idle 24µA, active 190µA, 1µA in sleep/watchdog mode) and either log data or blink briefly every few minutes.
Could you post aprox. values of the capacitors and what diodes you used?
Thanks :-)
Thanks yes it is a good circuit for learning. The values of the components I used are shown below the schematic.
Sorry, I watched it on a small smartphone (3") and missed that :-)
Diodes-> Any of the types mentioned? Germanium type as they work best with low voltages (I used them in an AM circuit years ago, I think they'll conduct at around 0.3v already)
Nice work. how can i measure strength of FM stations only. Can i use RC filter or not. Also tell me where to put filter components.
Most important in energy harvesting is antenna yet no videos about that topic can be found.
grounding is also important
Question: Lets assume there is a source of electromagnetic wave and you made and put one of these collectors and collected power .. if now you put another one close to it will the power split between them or both of them will get the same power? i'm asking about conservation of energy
energy will always be conserved
Combine with large area flat plate collector on a pole, like N Tesla suggested,
and joulethief circuit and or any tech to improve capture and charge and you
can improve it somewhat.
Very neat little experiment :)
I will try this out tomorrow for fun and great video as always
Thanks
Ludic Science , did you use AC or DC capacitors?
Ludic Science could you provide me with all the details of the components?? I want to make this for a school project
what if you hooked this up to a baseball cage? I'm not sure, but I'd think it would have to not be grounded to pick up voltage.
Well, it's an absurdly low amount of current, but it's possible to do some pretty cool things with it already.
What is the use of the red capacitors?
And what kind of LED do you use?
i think the red capacitators are to make sure that the voltage can pass trough the internal resistance of the diodes
@@ovencore2549 Thanks bro now I can finally resume my project
Try to ground the centre of circuit between electrolytic capacitors ?
What kind of modifications can be done to the circuit to make it work like an relative radiofrequency meter?
You should try this again but with 12, 6 in series and 6 in parallel
Experiment with different heights, 6ft, 12ft, 24ft and on a busy street where there would be lots of signals
i got 60volts 4 my first experience but not able yet to get more amp
I used the same diagram , I used building coax antenna
So, and if I have ten or more circuits like this in the same local. Should be possible to increase the amount of energy stored?
Having more than one will be a waste of money. If you put a bigger capacitor it will increase the energy stored there is no limit, but it will charge slower . But also a bigger antenna will make the capacitors charge faster.
german77GL thx bro, I'll try something like that
Great video, i was thinking about doing this but at higher densities, RF units can be expressed in uW/m^2, so there is a lot of energy we fail to harvest with just one antenna, my idea is to create an array of antennas to draw as much of the energy as possible. Also optimizing the Antennas lengths to maximize reception and higher gains. What do you think about antenna design for optimizing energy gains?
I have the same idea.
build a wifi cage around your entire apartment so none of your signals get out and none of your neighbors' get in, simply harvest all of those spare waves for power
at what frequency receiving signal
224k and 1n4148 what frequency (90-100mhz) ?
1:50 - why does the voltage drops here?
because you connect a load.
@@ludicscience did he? He didn't conected diode yet
Dear Author Could you send scheme please. I didnt understand part of Diodes : 1N34, OA70 , 1N4148 ? Here 3 type of diodes did you used all of them for one scheme or you mean we can you 1N34 or OA70 or 1N4148? Thanks for attention.
Add a joule thief circuit?.. Maybe
What is the name of the diode
Tutorial please 🙏🥺. Please build this step by step. Can you do a bigger version please 😊😊
the andtena needs ground to work better and something else inductor is missing or no need ?
Hi, I am new to this stuff and was wondering if you could give me a list of items needed to build this? I would greatly appreciate it.
I got only millivolts.
thanks for reply
No problem with antenna.
Check antennA
You can burn a copper plate.Make sure not to clean it.Definitely,You should put wires..Connect the copper plate wire to the positive of diode and connect a wire to the negative of the other diode.Connect this wire to your steel roof....This will give you a regulated and clean voltage..
Wonderful explanation! Just a question. Can this be used as a voltage source for your Low voltage flasher?
The question should be, "Can this be used as a power source for your Low power flasher?" It's all about the energy. The video shows the circuit is hardly lighting 3V LED (i=5mA), meaning 15mW maximum. It's very dim, so much less in reality.
Unless you have a low power device that works with ~10mW, the answer is "no".
Is it possible to maximize the output voltage by Using high rating semiconductors in the circuit?
I just have question, if LED lights up from surrounding EMF / RF, dose it make weaker signal from WIFI? or Mobile Phone? Also I am wondering if it's possible to make the device which can suck those EMF radiation from mobile station?
Have you measured the power output. How long the atena must be to get 1mW?
What if we use supper capacitor
Not work
But how is the diodes placing?
*_15 of this circuit in paroral + a joule thief = Free energy for life ... of a LED lighting for life_*
Right, but look at how cheap the circuit is, would it be impossible to make thousands of these with little housings and maybe a printed circuit board and some decent batteries?
Each diode there has a voltage drop. How could this possibly harvest any useful power at all? Can it run a red LED?
Try a lot of wires of different lengths all connected at the bottom.
Another possibility might be like a multiband dipole antenna. At first not worrying about lengths, later there are frequency meters with spectrum analyzers ... could do the math to target wherever the peaks are for a given environment. Can anyone think of any reason any government has any reason to worry about harvesting any waste energy with all the energy concerns of our world's ever-growing population and strong push for green energy if they genuinely want energy efficiency unless it is all in actuality all about profit?
Hey man! I am doing this circuit as a capstone project for collecting energy from alternative sources. You seem knowledgeable about this stuff. Can you give me a tip on how can I increase the power of this circuit?
@@hossamabdelfattah424 Yeah hi. After watching your video I went looking for an antenna that could pick up multiple frequencies. The wire you have is fine being vertical, the thing is that this is about tuning/resonance and length is key so that particular length would be best at picking up a particular frequency (plus harmonics although more weakly). At first I was looking at multiwave oscillators but didn't understand them. Then multiband antennas like in ham radio. Turns out it's just a matter of having wires of different lengths basically. They are all soldered to the same place. This spot in a video shows some laid out on the floor being prepped: ruclips.net/video/8KHzsKYsZL0/видео.html
Look up ... multiband dipole antenna ... for more.
But ham radio frequencies are a lot lower than what you want to tune into perhaps if you might like to grab, say, wifi stuff. It's pretty close to a microwave oven. 5G is higher. Anyway, at this point it makes sense to switch over from thinking in terms of frequency and instead go with wavelength. Look up wavelength of wifi. There are two, 6 cm and 12 cm. Very short. Each leg of a dipole antenna (just means the connection is in the middle) is supposed to be 1/4 of the wavelength. So holy smokes we're talking about a wire that is half of 6 cm. At 3 cm total, and then you connect to it in the middle.
I think that means the wire running to your circuit from the middle of these wires should be short, however you might be able to use coax for something longer.
So anyway, just one wire at first as a test.
0:39 With the long wire removed for now, just solder a 3 cm wire in the middle of it to that point on the left, crosswise.
Then try it close to your wifi router and well away from it. If there's a dramatic difference, then we're onto something. Other lengths can be added to that same point, some bending required I guess.
Ideally you can eventually wind up with a bunch of different lengths tuned very well to the type of frequencies we tend to have in our environment. However 50 Hz or 60 Hz power lines would be altogether different, I can't comment on those. The spectrum analyzer I mentioned, that I bought recently, and am happy with so far, is a GQ EMF-390. Turned it on just now and seeing a peak at 2.43 GHz, that would be my wifi router and laptop talking to each other.
@@garyha2650 OMG, Master. Thanks a lot for your help; I will surely try this multiband dipole antenna. One last inquiry; as I told you I am having a capstone project about alternative sources of energy, and the required task from us is to generate or collect a noticeable amount of (power). So, even we got a sensible amount of voltage here but with a low amperage, I am not having a great power amount. So, any tip of how can I rise up the current? without changing the voltage?? Or can I use a Li-ion battery instead of the two electrolyte capacitors to store the energy??
@@hossamabdelfattah424 Nice to know its a school thing. Yeah we're limited by power however you might like the video called 'How a Joule Thief Works'. By the way, I never understood electricity until I started thinking of voltage NOT as EMF but as pressure, electrical pressure, electron crowding, not too much unlike air pressure, maybe that'll help some others too.
I appreciate the kind words. Now I'm hesitating to answer in case I fall from master level lol, oh well, I have to be candid so: Maybe try a supercapacitor? I'm not sure if they have lower leakage. I think the main thing is just very high capacitance, thus might not help much here. You may want to look for any capacitor with the least tendency to leak across the dielectric, not sure. At this low of a voltage, there may not be much leakage to speak of.
I would try something that might not work, the four diodes as a full wave bridge, the 3 cm wire at its middle soldered to where AC goes on one side of the bridge using short diode leads, the other AC to ground, and at first just try only that and touch the LED across the DC points of the full wave bridge. Then try adding one capacitor in parallel with where the LED will go. And then, if that works at all, what would happen with some more 3 cm wires added, maybe at angles to the first. Maybe some others of different lengths. And then maybe adding some of the elements in your diagram could improve it further from there.
For the diodes, try Schottkey, maybe SB1040. I'm only saying that because I found out just hours ago from this: ruclips.net/video/kvWZjM1AcG4/видео.html
Ok time to roll up your sleeves and try things, looking forward to learning what you find out.
PS If this ultimately winds up being less than you would like, another possibility consistent with the capstone project theme that I also ran into today is 'Atmospheric Electricity Powering a Corona Motor/Electrostatic Motor'. He gets it working at 4 minutes into the video. No need for a drone, can use helium balloons to raise the wire. But up there, instead of wires with points, use a flat aluminum foil disk (maybe on light cardboard or glued straws or balsa to keep it flat) for lots of surface area. A point is great for *emitting* electrons, they all want to get away from each other and out into the air, but all trying to crowd in toward a point from the air they're not so onboard with that :)
@@garyha2650 What about charging a battery instead of storing in capacitors?? And It seems that in your opinion you think that harvesting RF won't be efficient in real life scale? meaning that I shift my idea to the atmosphere electricity? Will that produce a considerable amount if applied in real-life scale? --I am building a prototype that should be applied as a real-life project, so the power is the main concern--Thanks again Mr. Gary; I will be honored to document your name in the acknowledgement section of my poster.
can you design this to charge usb powered devices using something like sheeted metal roof as an antenna
Jose Cardona Yeah, but at that point you might as well use a solar panel lol
No, he meant already existing metal roofing as an antenna
I know, but most of the EM radiation would be from the sun any way
If that was true, your phones and radios would not work. Those signals have to be way stronger or otherwise they are "down in the noise"
Krisztián Szirtes Wrong, you simply sort out the different frequencies. Light has a much higher frequency than radio waves and so that is why they don't interfere. Sunlight actually has more energy due it it's intensity (higher amplitude)
Sir,
What is the number of capacitor and transformer used here?
There is no transformer here
C1 and C2 are 0.22 uF ceramic/polyester
C3 and C4 are 100uF electrolectic
Do make multiple of that so that you can make an higher power output to light enough the LED
What about getting a fixed voltage as output? How can we get a fixed output, and which is nearly 5V ?
