Never in my life have I had access to a mind like this who explains complex processes in such an easily understandable way - thank you RMS
cheers mate
I didn't really understand what he said but it sounded fascinating! I may have to watch this a few times to get a better understanding. It's 1am how am I going to sleep with these images and words I can't even pronounce whizzing round my head! LOL
@@poosmate I watch his videos over and over. I learn something new every time. So to whoever said nothing new here. You either already know all this or you have the attention span of a house fly.
I have a very short attention span myself. So I have to watch several times. Just so it sinks in but once it does. I am amazed by his ingenuity and knowledge.
He is the super hero without a tights and cape... More role model type for me... Tights hurt certain areas

Timeline - 08:55 - ""The bit I'm interested in >>> because I'm a chemist",... is what attracted me to this chanel many years ago,... RMS is a great inspiration to those who can THINK BEYOND their (studied) discipline,... !!! BRAVO
.
lol - cheers mate
I WORKED IN A RESEACH lab at the United Kingdom Atomic Energy Authority and did things no one in the world was doing, however, I never met a mind like you have, I think your up there with Michael Faraday.
I understand about 10% of what this chap says - which is "awesome" and why I watch every video ;-)
Watch it 10 times from different angles 😂
this one did have a lot of info in it mate
lol
spot on mate
@@Buzzhumma Naw, just watch it Once more, but through a Fresnel lens.
I absolutely love watching your videos, Mr. Murray-Smith. You've developed a wonderful teaching persona!! Thanks for your amazing lessons.
Wow, thank you!
Totally agree,,,,,,I'm 42 year old roofer that never leaned a thing in school,,,,,I could listen to this guys knowledge for days taking everything in like a sponge,,,,you are am incredible teacher sir 🫡
you make things that re usually overwhelmingly complex sound as understandable as a cooking recipe . amazing teacher .
I'm glad to have found this video. I recover parts from tvs. The recycling centers I've gone to said that the LCD screen will just go to a landfill. Now I have some idea on how to deal with them.
Thankyou I'm going to philippines soon to live off-grid in a 20 foot shipping container transformed into a fabricated exspandable 5 room mobile home loaded with good excellent Australian hardwares and whitegoods that we can't purchase in Philippines but is like owning a goldmine in Philippines now I'm a strong minded believer in selfpropulsion mechanics and your channel helps us to get free energy from many items like alternators generators collecting power through momentum weighted science. Thankyou.
I needed you as my chemistry teacher instead of Mrs. Key.....
Live watching this man as a generalist I understand about 90% and love that he gives links for more
cheers mate
I have come home from a bit of a hard day at the office, lots more COVID changes to make to so much that we do. Stuck Robert on and now watched about two hours straight. Not a minute wasted - Thank you Robert Murray-Smith every video is fascinating and educational.
Dude, your videos are the best! So much knowledge and information! I can now work on turning my garden into a self sustaining energy source without having to spend money I don’t have! Thank you kind sir!
This is truly working to a better tomorrow! Free energy from waste.🤔
You teach like you're just learning things as well with excitement which makes it easier to learn than when a teacher acts as if they have known for years and the people they're teaching are dumb.
Explained both clearly and made interesting, great tutor. Iv always taken things apart, fixed things, and tried to make things from broken things, this stuffs great 👍
Wowza! Thank you, Mr. Smith! So glad to have found you.🖖
So so so much useful info here. I felt like I had ADHD watching it. I had to review it a few times and it looked like you knew that. Brilliant!!!
I have fallen deeply in love with your brilliant mind! May I come stay in your workshop? LOL. You are amazing! Thank you.
One of those videos (and channels) where just the one thumbs up isn't enough. Totally awesome content. RMS is a 21st Century renaissance man.x
That was REALLY cool!!! I would have LOVED to see you come back with the end product at the end of this video! That was a LOT, you are correct. But DANG!! I understood some of it after only the first watching. I think I learned more in the this video than my entire semester of college chemistry! Thanks!
A wonderfully nice man and a genius too! What a rare breed of man!
So much cool stuff in monitors and TVs. I’d love to see if that linear fresnel lens improves efficiency on a solar cell.
So would i, and every one else with a solar panel on their roof that watches this.👍
That would not be hard to test.
test it mate then do a video
You are really laying it down in these videos! pretty advanced and lot of info but very interesting stuff
Glad you like them!
Thank you for such interesting practical videos.
Dive into other of your videos to find more details "how to", as my zero knowledge level is not enough to do it successfully.
Very well explained, Robert. Thanks
Welcome Robert. My but you are , Just what the World needs Right now !
always learning something new on this channel. priceless!
Glad you enjoy it!
So far you have given me many ideas to get out of the hole I'm in so thanks. I have a route to market so now it's just the testing phase to get a reliable and consistent product. Fingers crossed.
Another great video and more too think about thanks mate
Best of luck!
@@ThinkingandTinkering thanks mate. I've got some other work coming in too so hopefully I'll be a member very soon. You are awesome
This makes me want to study chemistry. Thank you for all the detail. Looking forward to what comes next.
You're most welcome! and I would certainly recommend chemistry - but I am biased lol
Insanely, brilliant video. Thanks so much.
Thanks for your experience sir
Your knowledge multiples , Nice !
I didnt even mean to watch this this. it was just so damn enthralling
Appreciate your time and expertise, and explainations of...
Good job sir enjoyed your videos
aaaah the continuation.
He saved my day.
Thank you for the vid.
You're welcome lol
Full on video, might need to watch it a few times to make sure I get the process right. Great video, going into saved list!
yeah there is quite a lotion there lol - make sure you have a read at that paper too mate - title in the description
@@ThinkingandTinkering cheers mate, will do.
May I say you are really awesome, I wish you had been one of my teachers.
Brilliant utilitarian resourcefulness. Thank you for this video.
glad you liked it mate - cheers
That is very useful. Thanks for sharing mate!
Glad it was helpful!
I don't really understand and probably couldn't even pronounce some of the words you said but WOW! However, I did also thing "Ah so that's what it looks like and how you recover it!". My brain is like a hard drive that needs defragging. I struggle to understand stuff, then suddenly the brain defrags (the penny drops) and I understand. Thank you for posting these wonderful videos, I love them! Take care, Poo
glad you liked it mate - thanks for taking the time to post - cheers
nice job , thanks for sharing
Thank you, very interest and admirable how much knowledge you master.
Ah the age old scientific statement; "That's a bummer. But that's the way it is". : ) Please keep up the excellent work
Fantastic. Always love your videoes.
Dang! I coulda had a sweet side business as a TV installer recovering indium tin oxide from all the broken LCD panels I had access to over the years, I did take apart a couple and kept some LED backlights and those focusing sheets - apparently you can construct an LED lighting panel that feels more like natural window light from the focusing sheets, which was my plan but I don’t really have the space to rework a 65” panel in my little place now - once I move it might be more of a possibility but harder to get ahold of expired TVs where I’ll be.
Thank you Sir, for this knowledge. Grateful.
Hahahaha! Bo, I so, SO love you right now! I've been collecting tv screens for about 4 years now for the gold in the displays but I never threw away the glass. I knew there was SOMETHING! I could do with it. I just hadn't found the process yet. I've probably got 1/2 ton of glass or more so yeah pretty happy right now. Thank you so very, very much for explaining this.
Any tips or uses for glass recovered from old plasma screens?
awesome mate!
Almost the scenario as for me, I haven't saved that much but I've kept the glass to discard off in a environmentally way, and then I found this video. Nowhere else have I heard of this Indium recovering from these panels.
Dear mr Robert. Could you do a video on recycling processes on a refrigerator? I simple love your Channel. You are so kind and interresting and devoted to your teatching! Regards Martin
Thanks for the video Robert! Really enjoying this. I would be interested in the generator.
Cool, thanks
Great bit of information.
Thanks for my new favourite channel.
Wow, thanks!
I loosely framed a piece of circular fresnel lens from a 60 inch flat screen and in the full summer sun, at just the right angle, the cement on my back porch would begin to explode in layers. That's hot!👍🤓
Another gem of a video!
cheers mate
Hi Robert, wonderful video!! can you give some hints about how can you heat up such a big glass while spray the chemical to it without shattering the glass? and do you think a DSSC made this way can generate sufficient power? isnt the glass too high in internal resistance? thank you!
Extremely interesting thanks.
Yes please would you mak the 2N3055 video I know what to do but others may not
will do mate
@@ThinkingandTinkering I used loads of them when I worked for Farnell electronics making the linear bench top power supplies you may have seen them ,well that was my first job in 1988 when I left school
A bit over a year ago I dismantled 2 LCD screens and threw away them ITO parts, so now I am a bit crossed since I could've gotten indium off from those parts dang it. I did one LED lamp out of the other one. Although its quite weak at emitting light, it might be good for a light table for drawing purposes for some, one A4 fits almost just on it. Gotta ask for more screens from people to recover that stuff.
Hey Robert, long time viewer here. I actually work at a company that coats glass for auto-darkening mirrors. And one of the main components is ITO. Over my years I have acquired various size scrap ITO targets that were broken or too small to continue to use and have always planned on doing something with them. I would love to send them to you for various projects if you'd like.
mate that would be awesome if you are serious - my email is robertmurraysmith64@gmail.com if you care to drop me a line
@@ThinkingandTinkering I just moved recently so I have stuff everywhere and haven't done much unpacking. So I'll see what I can find over the next few days. And if not I'll see what's laying around the shop. But I'll definitely contact you either way.
yes please..i would like to see a video of how to make that generator..........your videos are awesome..thanks.
Hey Robert, great video!! I have been dismantling hundreds of monitors from this one dumpster that just keeps on filling up with them. The problem is when I scrape off the substance on the dark glass the dust is not a black color but of a white color. It seems to me to feel and look more like plastic than anything else. Thoughts?
I repair a lot of tvs from the trash I normally avoid tvs with broken screens, didn't see any value in it, cheers mate I might try recovering indium
Wow. So thankful 🙏.
Wow! Great info
Glad you think so!
I'm curious which method you'd recommend to cut up the conductive glass into smaller pieces without losing its original properties.
I love your videos man! I plan on doing this myself and make a few bucks! : )
Awesome Video
Glad you enjoyed it
Rather than scraping the ITO off the glass, what about immersing the glass directly in a bath of hot oxalic acid, a bit like an etching tank? I guess that some chemicals from the glass might leach into solution, but as you said, leaving it for a few days will precipitate them out. Would that work without crushing the glass? (and save a heck of a lot of scraping...)
Good Q. I'd like to know too
I think I got it. The acid leeching components from the glass would probably damage the surface of the glass, which would spoil the optical purity.
im wondering what u think would be best of material to put up in the air an get static ion collection would love see vid on that idea
I'll be back for more! Good stuff :)
cheers mate
Yes there is interest in setting that little generator!
I'll get it done
Thanks for sharing knowledge
How many screens would you need to supply a three room household apartment ? And what do you think about the possibility of designing a project that supplies solar panel made from e waste ? How less expensive would the cost of solar panels be in the end?
Fascinating
Hi, will mixing aluminum powder with zinc oxide and apply to high temperature conductive glass give the desired effect?
Great Video!
we used to trash these thank you ---sir---vey nice vidieo---do you know if this will disolve plat -rhodium--in ores--?
Thank you Robert. I did enjoy this video. Have you heard of the Carbon Dioxide Battery yet? Their getting 500 hundred cycles from it. Maybe you could build one of these in your lab and do a video about it?
I will check it out
Another amazing video, through I was a bit concerned by the 10 seconds of screaming at the 15:40 mark. I thought one of my neighbours was being murdered until I paused the video and the screaming stopped.
Hope *your* neighbours are okay !
I rewatched from your marker I didn't hear screaming on the vid mate - it must have been your neighbours
Andrew Megaughin yes, I had the same experience - just at double speed..it’s definitely there in the original and not in your head!
@@David-yo5ws I also heard the screaming - and also had to pause and rewind to convince myself that it was not my neighbours.
Thank you please if you have anymore info on indium recovery or were to find info on separation of tin .i have recovered gold silver paladium and a small amount of platinum but have saved hundreds of displays hopeing to collect indium as my experience grew .thanks again your videos are great.
check out the paper I mention details are in the description
@@ThinkingandTinkering ok. Thanks again
hey man, think you could make a video of how to easily scrape off the material that stops the more clear glass from conducting, im having a hard time. everytime i scrape it, the glass breaks...
Nice. Is the fernel lense like lenticular lense the same?
Definitely a subscriber now. 😁
I wonder if you can use a cnc router to grind those layers off. Place the glass, adjust the height, let it run across the whole surface, collect the shavings, and then repeat on the next glass pane.
you only need to do that if you want the glass whole mate - if you are doing aa ton just for the indium - crush them up
@@ThinkingandTinkering You made great arguments for keeping the glass and CNC machines are becoming rather cheap these days.
That being said, I was curious whether they had the precision and work area size for this kind of task. Otherwise we might have lots of scuffed up glass. Better to crush the glass in that case.
Facinating stuff👍
Glad you enjoyed it
Fascinating!
cheers mate
RMS - light on silicon - could you do a perpetual battery flashlight? ie, putting the .5V through a few caps and a small dc/dc converter? could have the mossfet either outside or open the cone collector in the light itself
I suppose so mate
If you melt the indium into regular solder does it lower the melting point of the solder? Say to use in removing electronic parts from circuit boards. Also could you mix it with epoxy and get conductive epoxy?
no ideate - give it a go and see
That would be awesome a generator from an lcd screen!!!
I'd have to re-watch for context and or cross ref, but sometimes u r on top of answering so: can u get the color filters off the panel leaving a functional panel? I'd think this would be advantageous for resin based 3d printing
Very interesting.
@Robert Murray Smith. Y the name change from FWG to TnT
Very Interesting mate
cheers mate
If you can now have ITO & Optical Glass at your beckon call without expense, you're now able to experiment with an unlimited variety of new PV chemistries and techniques. I would imagine you've got a lot of ideas you're going to try in the near future. Can't wait to see!
for sure mate
Hi , Can you make a video on how to make conductive film using ITO ( from powder) on plastic?
Is there a video for beginners that would give them the introduction information to many things you talk about. Would love to see it.
Adding those lens does work great but after your panel gets so hot it hurts the effectiveness I took some very thick heavy duty aluminum foil I just use thermal paste very thin to the foil to back kf my panels and slap all the extra aluminium heat sinks I salvage to that sheet on the panels makes a big difference especially if you mount the panel and len to a tilt and pan sun following base.
Awesome vid
THANK YOU
I had an idea to use a sheet of plastic or glass that is coated with indium tin oxide that then goes over a sheet of copper that has been heated with sulfur to make copper sulfide. And that is the solar panel of a junction of the copper sulfide and indium tin oxide.
Is the glass on a copy machine the same type of optical glass?
ok so if i make a solar cell out of the screen you were working on about how many watts would it produce before i use Fresnels and mirrors?
