Thank you for saving me from ruining all my parent's old soap operas.
Thank God I saw this video before I started experimenting with c.d.s!! Thanks Robert, you saved alot of people from wasting alot of time.
CDs make useful ear rings, but not much else.
If you ever tought about making those. Then you are lost and most likely fall for another bs. :)
@@lukasp.5243 deep down I knew there was something fishy about the whole thing!!
@@audiodead7302 They make better frisbees, bird reflectors and microwave experiments.
Jim, I agree.
Got an idea: cover a parabolic dome with CDs, then have them focus on a tank containing water, then have the water evaporate and activate a turbine,
there you go...solar power from CDs! 🙂
probably not the worst thing you could do with CDs
Unfortunately the material in the CD has only a short life span when aimed at the sun every day. I tried this on a large defunct satellite antenna...
I clicked on this video because I was real excited to learn what I saw people doing a few years back. They powered their whole property on home made CD Solar panels. And they worked great. Bummer to see you just made this video to say they don’t.
I do not think you will ever be able to stop misleading videos (I am being kind) but as long as people like yourself are pointing out the facts we will have a chance. Thank you. 👍🐝🌞
Really? RUclips can't Stop misleading information? Why do they keep banning people? They seem to only ban smart people. RUclips loves idiot's
Amazing videos.. easily among the best content in the whole internet
oh Wow, thanks for taking the time to say that mate - cheers
@@ThinkingandTinkering i don't remember for sure, but did you do a video about printable solar cell's?....can you use a printer to create solar cell's?
@@ThinkingandTinkering what about if you covered the cds with leds?
@@deanstalker7964 Then you'd have shiny CDs. Not a bad idea, but.... oh! You meant to use the LEDs to generate a current! AHAHhaahahha! You're funny. I'm slow.
He didn't do nothing at all, just turning the CD on is finger, not even disproving that it could work, and you call it the best video in the entire youtube...In what cave do you live...and you got a cheers for it FROM the dude?????????? WHAT🤣😂🤣 FAKE
Best use I have ever gotten out of old AOL CDs was to hang them in the trees around my garden to keep the birds out.
That and they were killer frisbees
It is great to have this kind of video in this media where people would gladly believe something they saw once and not question the science behind why or why not it would work the way they are shown. Thank you for explaining to us.
👆Your useful message are good but follow the easy way of making income,.....Tell Andrei jikh i referred you👆✍️
He hasn't even showed how it doesn't work just how he thinks it won't. You have taken his word based on faith and dismissed the video showing evidence. Based on 1 man's words
Thank you for making this video !! I saw one of these videos the other week and thought “there is no way that a CD can be used for solar like that”
👆Your useful message are good but follow the easy way of making income,..... Tell Andrei jikh i referred you👆✍️
True--and not like that, but y'know, old CDs might not make such a bad backing for solar cells, or mirrors to reflect light toward the solar arrays... Better than throwing them out, anyway.
we will all be watching your videos Robert you have a great community built up around your channels. thank you for all your hard work and putting this type of content out there. 👍👍

I use old CDs for bird scaring devices, works a treat.
I use them as coaster 😂
I remember one of the other videos argued that regular cds won't work. They said it required writable dvds because those contain silicon. The regular cds and DVDs that aren't purple, are plastic mass replicated products which are pressed, not burned. Silicon was argued to be the "game changer"
The blue/purple colour is from azo or cyanine-type dyes. Neither of those dyes has silicon!
I worked at a company which build the machines to manufacture CD's/DVD's neither the ordinary nor write/rewritable ones contain silicone.
They use a thin layer of metal which is been sputtered on as a reflective layer as well as a light-sensitive dye for the (re)writeable ones.
We experimeted with all kinds of metals for the reflective layer though, copper gold platinum you name it we tried it, silicone was none of them though.
But Aluminium was the best cost/reflectivness compromise.
Like einstein
Your expose’ is appreciated…thank you.
I just saved 2 weeks, 17 liters of coffee,2 packs of calming meds and my faith in humanity, just by watching this video! Thank you so very much! Much appreciated!
get blood work done and see which nutrients you are deficient in
Thankyou Robert, it's most elevating to hear the truth and to expose the scammers, there's so much lying junk on RUclips these days. Keep up the good work.
The guy didn’t prove anything, he just gave his opinion. I thiught he was going to prove it instead of just talking about his opinion
It is truly amazing how well these "gag" videos actually work as a pay off.
It only works because RUclips doesn't care about misinformation
@@kevinroberts781 I suppose in a way, everyone who "tries" to make it work, will learn a valuable lesson.
Agreed, I'm thinking of sticking two wires into a dog turd and claiming it produces energy when put under your pillow. I'm curious as to how many idiots will actually try it.
Heat your pillow while you recharge your cell phone from compost?
It's amazing how many believe in the free energy videos and all that stuff.
I like your final words, how it's not stupidity. Strikes home, because when I saw the title and was not yet aware that it's a debunking video - even if that was at the back of my head - I was really excited for a second about such a simple solution to the problem that we've got, as you put it.
Thanks for being a stand-up guy.
It's pretty obvious that it doesn't work
@@kevinroberts781 If it's that obvious to you then perhaps you suffer from a closed-minded overconfidence. There's no reason to have assumed after reading the title that there isn't some interesting way of doing this, like applying a film the existence of which you are not aware of. It's possible to turn clothes into solar panels, so why not CD's that most people understand just as 'technological stuff'?
@@Ilamarea "curiousity kills the cat". I mean, why do we have to fall for it? I mean, if the trick is to put solar on top of CDs, that count as a trick.
Glad you made this. I hope it really helps dismiss the junk.
👆Your useful message are good but follow the easy way of making income, Tell Andrei jikh i referred you👆✍️
Have not seen those clips but your the Man ,thanks !
I'm very happy you're addressing this scheme and exposing the very basics of why some shiny, glittery plastic and aluminum isn't going to begin magically pumping out power... Other than the power of fantasy.. which would probably stand more of a chance towards an aha idea going through just the right mind at the right time. Thanks 👍
glad to see someone who is producing factual, useful information regardless of view count
I went through the better part of the video hoping to hear something along the line of "But here is how you can harness the power of the sun using nothing more than common table salt, some copper pipe, and these 497 CDs"
Thank you much Rob ! I was waiting something like this .
cheers mate
I was actually looking for one of those cd videos to try and understand how they work, glad I found this video, still going to try some of the other DiY options for solar though, just enough to charge batteries.
Thanks a lot from Turkiye MR. Robert. and Thank god there are honest Real Science man people like you on youtube.This channel deserve views more than millions.🙏💯
You could construct a parabolic reflector with old CDs to focus sunlight on to the energy convertor of your choice...
my guess is you will be making a solar oven, a better choice than aluminium foil if you can¡t afford mirrors, tho...
But I was going to Toshi station to pick up some power converters!
thanks for opening our minds
Your fun to watch. Very charismatic and informative. Enjoy your channel alot.
Even with my limited knowledge of electric systems when I saw these types of videos I was nahhhhh that can't be real . Thank you for the insight
You don't need 1million views Robert - it's quality not quantity that counts. Your videos are quality and that's what serious viewers want. Let the sheep see the scammers and you continue to give us serious students of all sciences the quality videos we need and love. The added bonus is that your videos are also highly entertaining. Well done.
Why wouldn’t I watch your video and appreciate it? You saved me from being conned Thank you so much for saving my time sir..
I did sucessfully harness the energy from the sun using a few hundred old CDs, suspended with old monofilament fishing line into an excellent, reflective bird deterrent around my garden.
Ah, the voice of reason! I was gulled by one of those scamvids and was tempted to try this for myself. You just saved me all sorts of time and grief. Thank you so much!
About cd .. .. If you have a CD player and do no longer need it, you can take out the ejection system. Thing is: if you put an LED (or two in reverse) on the motor and operate the eject mechanism (open, close, open, close), the leds will light up. And yes, there is another motor in the middle, but you will need to spin it a bit faster. The nice thing of the eject system is that it has gearing in it (See Rob's previous video about making your own, 1 to 128 ration).
The CDrom can be used to create a capacitor, not very spectacular.
The best use I know of for a CD is in the garden, hanging (dangling) from a rope, to scare birds away.
Debunk them all !
This and the lecture of the "Skeptical" saves a lot of effort for the lazy maker.
The fun fact is that it will work as rectenna / LEctenna if you have germanium diode on it ;D It doesn't produce much, unless you live near transmitter, or have your own transmitter. The CD has nothing to do with it.
yes it will!
So will an antenna.
I seen a vid years ago where the maker attached a joule thief to an antenna and lit an LED.
I think he had a germanium diode in the mix as well.
@@scotttovey Yes :D I'm currently studying if it might be possible to make portable AM rectenna to power 1,5v FM / Mp3 player... Biggest issue seems to be sourcing genuine low voltage UHF/VHF/RF diodes for cheap. Those good old germanium ones are nearly 1€ a peace + shipping. The CD actually might work well and be better with "spider coil" configuration. But I'm also going to use some LC magic, so I will try some dark green or dark grey (Mn-Zn) toroids to get more power.
Back in the day I had an AM transmitter (tube) and when a TL light was a few meters away from the antenne (just a long wire) it would light up. So you could play 'star wars' in the garden LOL
We just hang them all in our trees because if you string them together in a long line they make and amazing light show in the garden. Also our neighbour hates them and that is a bonus :)
Thank you for your youtube videos. And seeing someone that seems to love life and the real mysteries it holds.
👆Your useful message are good but follow the easy way of making income,..... Tell Andrei jikh i referred you👆✍️
Thanks a lot this clears all the errors
Thank you for very good advice.
It's amazing how many suckers are out there.
You can use clear lens LED's in this configuration and read a small voltage but it would take literally millions of them to make any usable power.
They incorporate non--reversing diodes in REAL solar panels to keep storage battery power from from backing up into the panels at night discharging them. If this happens, the solar panel will emit light in the infrared spectrum. LED's work basically the same way but with visible light.
Well I saw it, liked it and will be linking it on all those other videos
I really enjoy the way you dispel the fake video’s! 👍👍👍👍👍
Come on, let's hit that 10 million+ Robert! 💎📀💿
Thank you for setting us straight.
i lived in a block of flats and we were plagued by pigeons old cd's make excellent bird scarers - drill a hole on the edge and clip a fishing swivel to it, a few of these strung along a wire will keep the birds away from your seeds as they spin in the wind

Thanks for doing that Robert.
Great! Thank you for this video 👍
ok, maybe wanted to think i could save the world with some cds im not using anymore...didnt try it but thank you mister for the slap in the face, really appreciated
Thank you for clearing this up. Your videos are one of my face checks go to. Keep up the good work
Thanks, Robert! Look forward to your future videos.
It won’t get the views...but it will get the appreciation from the smart ones. Thanks. I love a good debunker.

You crack me up, I love to watch your projects and inventions. You bring so much fun to it all. :)
Simple solar cell can be built using copper cladboard .
yes - a copper oxide cell
Bravo........I tried one and didn't work to.......I didn't expect it to.......great experience and experiment......the prism is worth more.......explain ...diopolar plastic and alum......cheers
Spot on and well explained but this video will never go viral because it goes against what people hope for when they look at a bunch of cd. These guys who get paid for misleading cd solar cell info will not stop as long as the money rolls in. Thank you for the blunt honesty.
👆Your useful message are good but follow the easy way of making income,.....Tell Andrei jikh i referred you👆✍️
I actually made one solar CD wrapped wire myself, just to try it. In the sun, it did produce about 3 volts, but not enough amps to speak of...it has to be in direct sunlight, or it won't work. It works, but not feasible due to it having little power output.
By wrapping wire around the CDs and sticking them in the air you will pick up radio frequency energy and if you run it through a diode you will see small amounts of voltage, a long way from a solar cell however.
thanks for that saved me some time copper wire and cds always a plessure to watch real ideas
Thank you for your logic Sir
It's all about the hits and likes.
yes it is
In the one I watched, the guy twisted many wire ends together but forgot to hide that he hadn't removed wire insulation.
Bare footed in a lush marshy field he risked electrocution from the kilo-volts output from those connected100 cd's.
5000 hearts for this sir. 💞👍
It can be used like any little mirror to reflect sunlight on a black pipe filled with water to warm it, for example. If you have enough of them arranged well and the sun shines bright at the right angle, you may be able to boil a pot of water with it ;)
Or a bung overlapping to for a dish that concentrates rays to a point, but as Robert pointed out, you could do the same thing with alumin(i)um foil, or mirrors
I'm really not sure why you would since CDs make _really_ shitty mirrors. Just use something actually reflective and actually efficient.
@@NightRunner417 You can get a hand-cranked little 20W generator from china for 50€. Tested them and they are pretty good. Stay away from anything plastic, however.
@@NightRunner417 That's probably why you'd opt for alumin(i)um foil or mirrors instead.
@@oakfat5178 Aluminized glass every time. Never half ass it if you don't absolutely have to.
I appreciate this video.
the Best comment under a video from "King Homemade" was that: "I found that using older vynal records work a lot better. The black surface absorbs more of the
suns rays producing much higher voltage output. Also, if you run the current backwards through the record, you can get what is called a "black light" effect."
i like that kind of humor 🤣
During the 1980's the US Army conducted tests on various sheets of metal, like steel, aluminum, copper, etc., connected a bit like metal roofing. Some did conduct electricity, but not as reliably as the regular solar panels. All a CD can do is act as a reflector, not a conductor such as a hard drive metal disc, which I have tried and with disappointing results.
Ahhhh… the real world. Can’t beat it 👍🏼
Thank you for your clear explanation. Why is it people fall for all the nonsense, rather than studying and having a basic understanding of engineering science.
Children should be taught at school how to discriminate between fake and fact.
To support your message, I just read all the comments and upvoted all the positive ones. Hope it helps and thanks for the truth.
These things remind me of the Barnum and Bailey quote: "A sucker is born every minute."
You could possibly buy a load of CDS from charity shops and sell them on eBay then buy a Solar panel from the profit 👍

Thank you!!🙏
Brilliant video, mate.
You could make a really good Capacitor Out of them.
G'day You just got me thinking about a almost constant power supply. Wind is the only drawback that is at a stop start but can almost be overcome with perpetual motion.
Like all weeds... Pull them out one at a time. Another great vid. Thanks Rob 😎

I did a small experiment with an old cd. Take a few zena diodes, connect them in series and keep them on a cd in sunlight. Then connect your multimeter in DC mode to the two ends of the diods . You will note rising power when the sun light increases. Check this and see for yourselves. If this does not happen, then pls comment here.
I thought it was to good to be true or that simple.
Thank you for confirming my suspicions.
Thank you for explaining this!
It is an interesting concept, shame it doesn’t work. I have seen so many videos and thought to myself it couldn’t possibly work. Electronics are an amazing thing and I think it’s great that people waste their time to learn something doesn’t work, that inspires the brain to find a method that does work.
This is exactly why when I see a video like that that looks convincing I always do my homework. And do my research.
It really is sad that this has to be explained, but we do live in a world that P.T. Barnum would have loved. In his time a sucker was born every minute, but today they are born every second.
LED's connected in an array form a solar cell, the opposite is also true.
ie Push current through solar cells and it gives light, you will however need a specialist camera to see it.
Remember Tesla Patent for receiving radiant energy? U.S. Patent No. 685,957
Maybe u could use those shiny CDs as top plate? But u would need to connect shiny surface to the wire. Tesla said that top plate should be metal covered with some insulating layer.
Arrange them in a parabola and point them at a tin can Stirling engine attached to a DC motor.
Good man, thank you.
Thank you, I almost wasted a weekend destroying all
old tunes and flicks 😅
Thank you for this!
You appear to be the most professional, trustworthy and with a natural passion for basic Physics/Science, so very sad that this is minority in mainstream education. There is lack of awareness that the simple ability to to inspire learning in children and students of all ages is THE IMPERATIVE. Do you think it's simpler to buy inexpensive solar panels than attempting to make one with old cd.s,I too thought why are they missing the most important simple point about connecting? Any bit of solid plastic in-between must for a perfect Non Cercuit, it seems like some kind of clicking con.Are people really so gullible, it never ceases to amaze.Thank you and keep up good and valuable work.
great video Rob
Amazing its very helpful and save money.
I'm happy that we got electricity out of socket, so no need for weird tricks.
To use a CD as a solar cell you have to hook a wire to the aluminum layer. Perhaps by drilling a hole inserting a wire and using a conductive glue to attach it to the CD. Then attach the wire to the positive terminal of a super capacitor and the negative terminal to ground. Photons will knock electrons off of the aluminum and they will be replaced by electrons from the ground flowing through the super capacitor. Charge will probably build up on the plastic of the CD and have to be bled off through some sort of electrostatic motor or electrostatic conducting material back to the earth ground. Useful work energy is taken from the super capacitor it’s self. All in all it would work just the same and be easier to just use a sheet off aluminum foil. This is by the way an old Nikola Tesla patent.
The best way to turn a CD into a solar panel, is to buy a solar panel and throw the CD in the bin. You could sell the CD, but it's worth about 20p so you'd need quite a lot of CDs to afford a solar panel. It's more effiecient to bin it. You could use them as reflectors opposite to the solar panel, but my God what an eyesore.
By using a box of spanners, nuts and bolts and some recycled oil, I once converted an old rusty box and some round rubber things into a means of transportation. (Also called getting a car through it's MOT).

If it sounds to good to be true, by all probability it isn't.
But the people always want to see the next new wonder, the next new, easy and sparkling answer to questions not asked.
Because an easy answer, as wrong as it may be, is for some always preferable to really having to do something
I am afraid they do
Good tip about the mirror and washing line. Going to try it now. Lol
I love the old video where you cut the top off an old car battery and hundreds of dry cell batteries fall out. I laugh when I think of some poor sap getting battery acid all over to discover there were no batteries inside. Then cleaning up the mess.
