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.
Thank you for saving me from ruining all my parent's old soap operas.
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...
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.
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
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? TH-cam can't Stop misleading information? Why do they keep banning people? They seem to only ban smart people. TH-cam loves idiot's
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.
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
I use old CDs for bird scaring devices, works a treat.
I use them as coaster 😂
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
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. 👍👍
👆Your useful message are good but follow the easy way of making income,.....Tell Andrei jikh i referred you👆✍️
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.
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
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
It is truly amazing how well these "gag" videos actually work as a pay off.
It only works because TH-cam 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.
Thankyou Robert, it's most elevating to hear the truth and to expose the scammers, there's so much lying junk on TH-cam 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
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👆✍️
Your expose’ is appreciated…thank you.
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 👍
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.
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"
glad to see someone who is producing factual, useful information regardless of view count
Thank you much Rob ! I was waiting something like this .
cheers mate
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!
Have not seen those clips but your the Man ,thanks !
thanks for opening our minds
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..
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!
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👆✍️
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
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
Your fun to watch. Very charismatic and informative. Enjoy your channel alot.
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.
Debunk them all !
This and the lecture of the "Skeptical" saves a lot of effort for the lazy maker.
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👆✍️
Well I saw it, liked it and will be linking it on all those other videos
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 🤣
Come on, let's hit that 10 million+ Robert! 💎📀💿
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.
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.
It's all about the hits and likes.
yes it is
It won’t get the views...but it will get the appreciation from the smart ones. Thanks. I love a good debunker.
👆Your useful message are good but follow the easy way of making income,..... Tell Andrei jikh i referred you👆✍️
Ahh TH-cam... "If you can figure out how the sexy female scientist makes solar cells out of CD's, you're a genius!" There's a sucker born every minute (P.T. Barnum)
🤣
lol - now there is a thought
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
You crack me up, I love to watch your projects and inventions. You bring so much fun to it all. :)
I really enjoy the way you dispel the fake video’s! 👍👍👍👍👍
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 very good advice.
Thanks for doing that Robert.
Im getting a solar sized headache watching this.
Also.... have fun after the 1st rain contact. Lol
Well done with this public service :). If it helps, I wasn't looking for a video on DIY solar cells, but google just found it relevant to me (no idea why, it's been 10+ years since I search for anything like Overunity / Free Energy etc). I have never seen any of the videos that promoted this fallacy so your video must be gaining some traction with the funcy (or funky) youtube algorithm. Congratulations: At the time of this comment, this may not have millions of views but 1/4 million views still isn't bad. Hope more people see this before wasting time and patience on garbage. My thought process here is let the youngsters with a spark of genius and lots of enthusiasm try things that might work/need developing and not get disgruntled with rubbish.
Thank you for setting us straight.
Thank you, I almost wasted a weekend destroying all
old tunes and flicks 😅
Thank you for your logic Sir
Good deal. I saw that last one and thought.. I wonder what Mr. Smith would say?
I put it on the back burner so to speak..
*I HOPE everyone watches this!!* I had a sneaky suspicion this was clickbait..
Thank You Robert!! Always look fwd to your videos!
These things remind me of the Barnum and Bailey quote: "A sucker is born every minute."
Hello - there was a Polish science-fiction writer named Stanisław Lem once he said "until I used the internet I didn't realize there were so many idiots in the world" whatever he meant explains why movies like these with pseudo photovoltaic cells , made of CD - or it is a deliberate MISINFORMING action! You make fantastic material exposing and showing how modern technology works. Regards
You could make a really good Capacitor Out of them.
This is exactly why when I see a video like that that looks convincing I always do my homework. And do my research.
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.
Thank you for clearing this up. Your videos are one of my face checks go to. Keep up the good work
Ahhhh… the real world. Can’t beat it 👍🏼
Like all weeds... Pull them out one at a time. Another great vid. Thanks Rob 😎

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.
We need more wise gardeners like you😉...pulling weeds!😂

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.
Thanks, Robert! Look forward to your future videos.
Thanks a lot this clears all the errors
To support your message, I just read all the comments and upvoted all the positive ones. Hope it helps and thanks for the truth.
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.
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

I thought it was to good to be true or that simple.
Thank you for confirming my suspicions.
You could possibly buy a load of CDS from charity shops and sell them on eBay then buy a Solar panel from the profit 👍

Nice video, glad you made this Rob as I've been wondering why all these videos had been coming up last couple years.. 👍🏴🇬🇧
Thank you!!🙏
Nice one Rob
cheers mate
5000 hearts for this sir. 💞👍
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
Not condoning posting fake videos, but a little good does comes of it: People that don't know better, or should, do get some experience constructing something and testing it. There are worse things in the world. It will fail. But we do learn more from our failures than our successes.
At around 12-years-old, a friend and I got hold of a couple of Big Wheel tire and axle sets. We built a crude unpowered go-cart chassis for them. We had measured the width of the axles from the outside of each tire, not the inside. The axles would not fit the finished chassis. Doh!
Much was learned, though: Experience, new skills, and life lessons.
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.
Great! Thank you for this video 👍
Thank you for this video. I've been bombarded with this fake solar cell and knew it couldn't work. 😂
Brilliant video, mate.
You should repost this video on 1st of April. 😉 Thanks Robert.
👆Your useful message are good but follow the easy way of making income,.....Tell Andrei jikh i referred you👆✍️
Robert thanks for the content, I'm open minded and I will analyze everything that is out there, I was watching your video and occurred to me that maybe this is not a solar power but a rf antenna or a receiver.i like to read your opinion.
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.
Simple solar cell can be built using copper cladboard .
yes - a copper oxide cell
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.
I wonder if you can build one of those solar heating panels that people make with hoses in spiral shape, but use CDs at the base painted with black paint, so that it absorbs light but also the light that goes through the paint gets reflects by the CD back into the paint, allowing for higher effeciency.
Those do work as a per-heater for your water heater. Or for a off grid cabin. but in the winter these don't work quite as well in less the box is well made.
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.
Good thing I watch this. Initially I thought you had lost your mind. Good Stuff Boss 🤝🍻
Damn I thought I was going to save the world with my CD collection!
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.
Thank you for myth busting that one Robert.
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.
There's nothing like getting somebody with a British accent to say: "THAT sounds like a BRILLIANT plan that will not actually... WORK."
great video Rob
