This mirror is 100 times cheaper than mirrors for cheap solar electricity & thermal energy

Ғылым және технология

This concave mirror is made from expanded polystyrene and this reflective film at a cost of 25 cents per square meter, and it is several hundred times cheaper than these mirrors which focus solar radiation to convert it into heat and electricity, and such a radical reduction in the cost of similar mirrors makes their electricity cheaper than from solar panels, or thermal and nuclear power plants.
I have already made many mirrors from expanded polystyrene for this solar station which provided space heating of this house in the winter and heated the water of this pool in the summer during 8 years. But my solar station used similar polystyrene mirrors which formed a concave trough, while this video will show the solution to a more difficult problem when such a reflective film should form not a trough, but a dish.
Now I am showing another blogger’s attempt to solve this problem, although we see that he used polyurethane foam instead of the polystyrene. This is his mirror, and we understand that making a quality mirror is a difficult problem, but I was able to do it, and now I will show how my mirror focuses the solar radiation to this point, which will set fire to this piece of paper.
But before I got that good mirror, I made seven unsuccessful mirrors which helped me see my mistakes and the possibilities of correcting them. With the goal of seeing the problems and their solutions, let's look at my journey through seven unsuccessful mirrors to this successful mirror.
Now I will remind you how this unsuccessful mirror of that blogger was made. He used this hard surface with this hole, and now we see how he applies glue, but only along this circumference. After that, he put a reflective film and pressed it to that glue circumference. Then he used this pump which pumped air under the film through that hole, and therefore the air pressure gave the film the shape we needed. After that, he put a lot of polyurethane foam, but unfortunately, the hardening of the foam is accompanied by its unpredictable expansions which spoiled the desired shape of the mirror.
Many of you have already realized that the foam needs to harden on a solid surface, and that is why I used this satellite dish. Then I put down a reflective film, and stretched it out. I will put a lot of polyurethane foam here, and now we see how I did it.
This was my first unsuccessful mirror, and we see that it turned out noticeably better, although it is still very far from our wishes. Now we see that it is even trying to focus solar radiation, but it is obvious that I have to make the 2nd mirror with the addition of this circle of expanded polystyrene whose surface roughly matches the shape of that satellite dish.
The making of the 2nd mirror also began with the action that I placed a reflective film on the satellite dish, and then covered it with polyurethane foam, but now I have added that polystyrene circle with weights. Now we see that the 2nd mirror turned out better than the 1st, and it focuses noticeably better, because that polystyrene circle limited the expansion of the foam, and therefore it more evenly filled the space above that satellite dish. However, we can see that the surface of the 2nd mirror still has many defects, for example here, where the edges of the steps of the polystyrene circle are located. That is why I decided to remove these steps, and now I will show that the polystyrene circle for the 3rd mirror has a smooth surface, without the steps.
So, making the 3rd mirror starts with preparing this reflective film which is placed on that satellite dish and stretched. After that I applied polyurethane foam. Another difference between the 3rd mirror and the 2nd is that I tried to use as little foam as possible and increased the amount of those weights.
This is the result of that making, and we see that the surface of the 3rd mirror is still not ideal. Nevertheless, it already focuses solar radiation well here, and now this focus will try to set fire to this piece of paper. Unfortunately, the focus quality is not good enough to give the paper a fire, but it is enough to give it a smolder which burns a large hole in the paper.
That is why I have to make a fourth mirror where the foam was placed not on the reflective film, but on the polystyrene circle, like this, because it seemed to me that the upper surface of the foam hardened more smoothly. Now my fourth mirror will try to give fire to this piece of paper, and we can make sure that it solved this task very quickly.

    I think that you may want to reverse your process as follows, 1. Make circular frame, and tack on the reflection film, 2. " Top down effect" by pouring water into frame to achieve the curve in the film, 3. Use aircrete ( cement with soap bubbles) instead of foam, as the backing, 4. Place Air Crete under the curve made by water ( spray glue may be needed on the film to make it stick to the Air Crete, Green power science did this with wayer and clear plastic to make a large parabola curves,

    Hello Sergiy, love your work and want to build a rotating table on which paraboloids can be cast from plaster or concrete. I imagine one can make a concave paraboloid, in it a convex paraboloid, and use both as a heavy mold. A foil bag can be put in between them when they are spaced apart by 2-5 cm, and PU foam can be put in the bag. Then the foam will expand to fill the gap and exactly reproduce the shape.

    What about using pieces of bamboo? Split a bamboo into 4-8 sections with the mirror film glued to the inside of 75-100+ mm diameter bits of bamboo a meter long if more or less. Depending on what is required . Another idea is using air to make the dish like in the video, only use fiberglass on the film glued on first. Then add air. Attachment points can be add to the back side. Use a thin fiberglass and resin roll it on. Add air before it sets up. Even paper, cloth many things can also be used. Not really worth carbon fiber, but cotton cloth synthetic cloth or silk pre Made fiberglass attachment points can be made and glued on with resin. I would love to build a 1kw steam engine generator powered by the sun. Then maybe use propane, methanol, CNG, something with a low boiling temperature. To replace water. Maybe a mixture , propane and methanol possibly. Or CNG and methanol gasoline and propane, gasoline and CNG, the difficult part may be getting it to return to a liquid. Maybe a small refrigerant compressor can be ran at the same time as the generator. Used in short cycles to chill the gas to liquid to start the cycle over again. A pump pumping liquid through the boiler. A iron block with passages through it. For liquid And a area for gasses to collect and be heated just before the engine request it. Heat the gas well into the boiling point , and use a similar cooper or brass block with refrigerant passages chill, the gas to liquid to be stored until needed. It would be awesome if was effiecent was enough to use thermal electrics to make it work..

    I really value your videos because you focus so much on the cost / benefit ratio. One thing I've been interested in for quite some time, but not really done a lot of experiments in this area, is to create your own water-resistant / proof foam. I don't mean expanding foam like the polyeurathane foam, I mean something like creating a foam from glue that dries out and leaves the foam in place, similar to the foam you can create with washing up llquid, but where it dries in place and stays there. Also, what about using polystyrene foam but using something like a cheap, large CNC machine carve the surface of the foam into the shape you want? And then spraying the surface with glue, and expanding the film onto the surface? Ideally, what you want is a kind of fine grain, reticulated foam made from a rigid material where you can spray the surface with glue, and then expand the film onto it using air pressure, so that it all touches the surface of the rigid foam at the same time everywhere, and that would be both light, rigid and relatively cheap.

    Ok, but you're trying to make 1 solid mirror, and to make it from a sheet of mylar that doesn't want to stretch. If you're looking to make a focused point of light, that is say 3 inches, then if you simply make a frame that holds flat 3" mirrors that are hex shaped, then you can make the same mirror, but can replace individual mirror modules as needed from a mylar blanket such as you've shown. Additionally, each hex module can actually protect the mylar film, without adding significantly to the cost. Glass, or acrylic, etc, two piece units, where the reflective material is sandwiched inside. Individual reflectors could be replaced instead of rebuilding the entire reflector and because they use a hex lattice, they can be scaled as large as you want if you add more modules to the frame.

    I agree: I prefer your natural voice, rather than the bot. You are making good progress. I am not sure why you are focusing on circular mirrors, rather than linear mirrors, because you can hotwire rigid foam with CAD created parabolic templates very accurately, and hopefully create a very fine focus.

    a few things might help : a heat gun could apply gentle heat to the film during stretching, thus smoothing out those ridges. Secondly a second 'satellite dish' hard smooth surface, covered in something like plastic wrap could provide the ideal shell for weight application - like a sandwich. so you would have 1 dish, sealed and smooth that will have the film applied over it. Stretch the film and apply gentle heat to work out wrinkles and folds, then a thin layer of foam (which may have better solutions in the future), then a second dish, which is sealed and smoothed on the inside with a layer of plastic wrap if needed to keep the foam from sticking to it. apply clamps or weight as needed, wait until the foam is cured, then remove everything. This should make a more uniform 'bowl' dish shape, smooth and focus easier.

    just a thought, Sergiy can you make a exact opposite of the satillite dish and sandwich the polysterene and mirror when glued in between the 2 satellite dishes and place them in a vacuum bag and remove all of the air thus forcing the polysterene and reflective film together possibly with a smoother finish, if you are trying this method, try using contact adhesive(rubber based) instead of expanding foam this might help in the smoothness of the finished product, i just realised when typing you dont need a negative satellite dish just 2 the same size to sandwich the polysterene between getting the polysterence smooth on the side where the reflective foil is going to be will be tricky,but hopefully the vacuum bag trick will work, i would also look into whether when in a vacuum bag any steps you might need to take to prevent slippage of the mould before the glue is solid, but under vacuum that might not happen, who knows ?? good luck Sergiy :) :)

    Could you compute and graph a parabola on a piece of wood and maybe use that to turn a shape that could be used over and over again to create a mirror? Instead of polyurethane maybe use some kind of epoxy or plumbers putty make a negative mold and stretch the film over it and pour epoxy in layers over the film until it dries and is strong? Such a cool idea. I notice you said you were in Ukraine. I hope you are not affected negatively by the Russian military, or the Ukrainian government rushing you off to the front. You videos always interest me. Also, what about just doing this in two dimensions to heat up pipes like some of the other videos you made show. I was thinking it would be an interesting idea to investigate ways of making a cold and hot reservoir of water for heating and A/C in a home. Could that be done? Another guy on KZread made a small scale cooler by dripping water through some filters and cooling it down, and then pumping it over to another heat exchanger with a fan behind it blowing cool air into a room. But could you use cold water and hot water in a a room radiator to heat or cool the termperature - making use of a massive amount of water cooled cheaply? Keep making videos, they are so interesting

    That's all great, and I've seen your other videos, but I don't quite understand what are you trying to accomplish? If you're just showing individuals how they can do what you do at home, I think that's great. But if you have commercial use in mind, surely you don't expect some mirror plant to be torn down and replaced with the new one every eight months ort so. Now, depending on the location, there are PVC and/or polyester foils which can be vacuumed and don't cost anywhere near the glass mirrors etc. You can check Tech Ingredients channel, if I recall correctly, they have made some panels from that foil, and I think that material might be kind of middle ground which you seem to look for. Spraying polyurethane is also not the cheapest option if done one by one like you did in the video. As far as I could see, you've been testing your mirrors and other stuff on the improvised wooden structures at home? I mean for any commercial use you should also take the real structures into consideration, and probably you'll find out that the mirrors participate in the final price much less than it may seem at a first glance. I'm not criticizing you, on contrary, I think people should take much more interest in things which are surrounding them, and more importantly, are becoming critical factor in our lives, and look for possible solutions to keep expenses at bay. I'm just trying to understand what's your goal with the products you've been showing us in your videos...

    Sergiy ...... I am not sure weather or not you read the comments, but just in case I have an idea to improve the wrinkles out of your mirrors. You show a video of gluing a circle and inflating the film with a pump. This seems a good way to produce a parabolic surface. Why not coat the pumped up surface with a thin layer of an epoxy resin? That would give you a clean flat and stronger surface that you could then eather add more epoxy to give a complete mirror or use your expanding foam to bulk up the back of the mirror! I think the relative expense of epoxy v foam would mean a thin layer of epoxy to stop wrinkles and then foam would be the cheapest way. This also has the advantage of being fairly easily scaleable to fairly large surfaces. A similar technique could be used to produce linear parabolic mirrors like those seen in power plants. Obviously it would need a mould but instead of inflating it you would only need to glue the ends and stretch them apart slightly to give a taught surface to apply the epoxy to. All the best.

    You need to spray the back of it with spray mount basically a contact adhesive first then wait about 20 minutes and start spraying it with a filler paint probably about 3 or 4 coats.. the idea of greymouth is to stick to the reflective surface and the paint will make a hard surface you can then use spray foam which should not distort the mirror as it.. there may be something more suitable than paint which is harder but that you will have to experiment with

    Another way you could build a cheap and easy pattern out of foam then suspend a router from a string/steel wire from a point above the pattern. You could then work it back and forth and it would create a concave shape then from that point you could cover the concave pattern with plastic film, then fill in the concave shape to create a large positive convex pattern that you could then sandwich the Myler and some expanding foam to build a concave mirror.

    That would create a spherical shape, a parabola is more efficient, either by deepening the center, flattening the mid ring, or a combination of both, like a telescope mirror.

    Also: if you use foam intended for fitting windows/doors you'll find it is manufactured to expand less aggressively and more slowly. It spreads the force more equally.

    @Sergiy Yurko - Some foams exert no pressure and some exert large amounts. Consider expanding foam which is meant for plasterboard if you want 0 pressure and use pink fire foam for high performance. Tire foam is much more flexible and resistant to crushing.

    Build a stable Box around the Satellite dish, span the mirror foil over the dish. The Box should be closed over dish and foil. Now make a small hole to fill in the foam in the Box and close the small hole. Now the foam will expand and Press the foil against the dish. It should get smooth as hell with the pressure of the expanding foam. No other ways to expand.

    Why not apply a liquid that will cure into a hard rigid shape? Like an epoxy? I'm sure there are epoxies or laquers that can cure without an exothermic reaction that would leave the mylar undamaged.

    Could you do a video on a complete system? The mirror to heat the oil line or whatever to go through a diy generator that would change the heat to electricity to run 100 to 200 watts of appliances? I love your idea for solar mirrors. Edit: I can see how the oil would go through a heat radiator to heat, but would like electricity too.

    In fact, what about trying aerocrete? It's dirt cheap. Forms a good surface. Can easily be removed from a mould. Won't blow away (and/or can have mounts cast Insitu)... all you need is cement, water, an air compressor, some washing up liquid and aluminium sponges to aerate the soap/water mix into a foam.

    You're doing it backwards. You should first shape the polystyrene on the dish, then bore a small hole at the center, apply glue on the concave polystyrene, stretch the reflective film on it and suck the air from the space between the reflective film and the polystyrene through the center hole. This should give you the best shaped mirror, with minimal effort barring some wrinkling on the glue up phase, but that can be perfected later.

    I know it more expensive and not as durable, but how efficient would be a version that is either have a glass in front (I guess it will filter certain spectrum), and use the air pressure technique to get the perfect form ? OR use the reverse, a vacuum on the back of it so there is no glass in front. You could change the pressure to test different form.
