Дякую пане Сергію за цей довгий але дуже корисний експеримент. Для себе я зробив висновок що при мінімальному догляді за такою конструкцією термін її роботи можна подовжити рази в півтора. Якщо вся система буде як частина приватного господарства, то лагодити її не буде жодних проблем.
you should spray a reflective silver paint on the back of a new space foil mirror. Also you can spray a translucent plastic plaint on the front of the mirror giving it more insulation and protection. Additionally, you may use kitchen cling foil (saran wrap) to wrap the mirror in case you need to protect it more. These steps should prolong the life of your mirrors substantially.
Nice I would consider protecting back and the sides of the mirror with 95% transparent mesh to reduce wind, and make a shadow that would reduce plant growth. Maybe a small roof could be an option,. Other option could be to buld small greenhouse or box with a transparent front (glass/plexi) and placing mirror inside. That should prevent dust and snow accumulation and could increase lifetime of the mirror. Also would allow to ocassionally clean the front glass/plexi from dust. Maybe a pipe for heat exchange could also be installed in that frame inside of a box.
I think the added cost of insulating the back with some form of foam , painted white on the face closest to the mirror, but importantly filling the entire square surrounding the mirror surface. Foam being somewhat forgiving but not too much, should allow for the impacts to adsorb away from the reflective material, and the white will reflect some of the light that gets from the holes where the aluminum has dissipated. I think if we can double the use of this method to 3 years, that's slight more cost but roughly double your performance average, so what 7.6x more efficient than the other? Seeing increase in cost, let's say a conservative 7? That I think is a more viable business plan/design.
So I've been experimenting with making my own reflectors, and there are plenty of products that claim, "Ohh yeah, this gives a mirror finish!" but they are mostly lying. They give dull shiny surfaces at best. Until I found Krylon "Looking Glass". Rustoluem has a similar product called "Mirror Finish", and either can be used to create genuine mirror finishes on the opposite side of a painted transparent material. I like the Mylar blanket reflectors, but I wonder if you could vacuum form a cheap reflector and paint it into a mirrow, then seal the back with something for something that would gain focus, and durability without destroying the cost savings benefit?
Interesting update. How are the stainless steel sheet mirror holding up? I remember you mentioned them a while back and they seemed like the best option to me. Also are your mirrors made from chopped up household mirrors still going?
Bonjour et merci infiniment pour cet excellent partage : Une question s'il vous plait : Quelle comparaison peut-on faire entre la réflexion de votre miroir (feuille d'aluminum) ET un miroir classique utilisé dans les autres projet MERCI (..... ) Hello and thank you very much for this excellent sharing: One question please: What comparison can be made between the reflection of your mirror (aluminum sheet) AND a classic mirror used in other projects THANK YOU
Hey brother, I found how you can reduce the rate of deterioration of the mylar mirrors/space blanket mirrors. You have to coat the metal side with gloss black enamel spray paint. ( I don't know how necessary it is for the colour to be black but that's what I saw in that video ) I saw it in a video, if you want I can link it.
I was dying to tell you about this. But was unsure if you'd find my comment. Also the method I mentioned, can supposedly increase the reflectance of the mirrors as well.
Interesting... I could see a lot of stress marks on the outside of the mirror. I think the design could be improved if the frame was thicker and it had a back to it, then the wind would have less effect on it. Could the film be preserved better if you could coat it with varnish? Also if it were going to hail you could quite quickly protect the mirror by turning it upside down.
My main conclusion is that it's possible to be too inexpensive. No more mylar. Surely more robust metal reflectors would be a wiser component for any serious home heating solution.
I live in the Philippines and I think, given how long PU covers for the car last, the life of these would be considerably less here. Something much more robust would be necessary.
Would painting the back of the film increase its durability? you could use polyurethane roof paint which is already made to resist the sun and weather for at least 10 years. You could also coat the front reflective side with clear plastidip for cars which is UV resistant, tho the later might be more expensive than replacing the film.
Dear Sergly, what would happen if high absorption black ink is applied to the thermal electric generator's hot side, and what would happen when apply CaCO3 or Ba2SO3 based paint to the cold side? Also attach the space blanket via epoxy or acrylic or glue onto a flat surface might be a good replacement for curve metal sheet or small mirrors? Such small mirrors or strips of reflectors maybe able to construct a flatter structure like a diffractive lens/ Fresnel lens?
Spolzovoti nada shos smaller mesh shop ni zlamalo plinko (some thing that won’t tear the Mylar a mesh with flat sides. You can maybe get that from hvac units. Not sure what you can get in Ukraine today because of the war but hoping you can still get supplies)
There is one thing missing in the cost calculation: The costs of pollution. Microplastic and Aluminum (micro/nano) particles finding their way into the food chain.

Hy, if it will rain with "ice" (i do not know the term for this) your foil has no chance against it. Cheap is not always good. Until now, in my opinion the modified Satellite dish is the best solution.
Nice experiments ! I prefer still the long lifespan ones, with non corrisive metals sheets, mirrors pieces on concrete like also done on the fixedfocus channel.. Happy to have good news from you !
dear yurko.. war didn't stop you from experimenting and inventing solar.. you are a brave man.. thank you..
It is a joy to see the scientific method at work. Wonderful video!
Thank you for all the work you've done. People have learned invaluable info from your experimentation.

Cool project. That is important for the future. Awesome to see you keep going 💚

One could build a spinning tool and pour concrete into it that will harden with a parabolic surface.
Cheap…..
@@Maxim.Teleguz What's offensively expensive about a wooden tool hanging from a ceiling-mounted motor?

nice stuff, im thinking put this in a greenhouse and somehow focus the heat from this on to a sand container, it would release the heat at night?
Great video 👍

Yes. I think glass mirrors are the best and the most safe msterial. But expensive.
would glass or plexiglass prevent wind damage or and debris buildup?

Стальную проволоку нужно закрыть пластиковыми трубками ,тогда они не будут рвать пленку так быстро
How about double layer?
Я вчу англійську і мені зрозуміло. Дякую.
Does it boil water
