A new type of solar heaters gives us cheaper electricity (Motionless Parabolic Dish)

- We can find the following three types of Parabolic Dish Solar Heaters:
1) Its mirror and receiver move together
2) The mirror is moving, but the receiver is motionless
3) The receiver is moving, but the mirror is motionless
The 1st type is widely known. The 2nd type is used very rarely and is only known to a small number of experts. The 3rd type is unknown, and this video explores it, but my more detailed video of its experimental and theoretical research is: • A new type of mirror s...
We can find 3 types of similar solar heaters, and now I am showing the 1st type. This concave mirror focuses solar radiation into this receiver similar to how this little mirror lights a cigarette, but our large mirrors will turn solar energy into heat and electricity. However we know that the sun is constantly moving across the sky, and therefore our mirror must be constantly turning.
This type is widely known, and we may have seen this 1st type many times, unlike this 2nd type, which is known only to a small number of experts. This mirror focuses solar radiation in this way on this receiver which is motionless, but the mirror moves according to the movement of the sun across the sky. At the same time, we now see that the mirror of the 1st type must move together with its receiver.
Of course, our brains can come to the conclusion that there is also a 3rd type where this mirror is motionless, but this receiver is moving. So, the 3rd type should be similar to this experiment of mine.
It is incredible, but this 3rd type is unknown to mankind. Nobody has tried to research this type, although it can provide very cheap heat, steam and electricity, because absolutely motionless mirrors are many times simpler and cheaper than such complex structures of solar heaters of the 1st or 2nd type.
I remind you that such solar heaters can convert solar energy into heating some liquid or air with a temperature of several hundred degrees. Then this thermal energy is used to generate steam for a turbine or comes into similar heat storage to generate steam and electricity at night.
Our unknown 3rd type began to be investigated by me a few months ago on the example of this very cheap mirror which creates this spot of focused solar radiation.
Let's look at how this spot moves from morning to evening due to the movement of the sun across the sky. Now it is morning, and we pay attention to this screen, and here we see that spot of radiation from my mirror, and time points of one day on the 4th of December are shown here. We see that my mirror is absolutely motionless, but the screen must move, and now I will show the same, but more slowly. At the same time we see that this spot is always inside the screen which imitates our receiver where the spot should heat some kind of heat transfer medium to a temperature of several hundred degrees.
My 3rd RUclips channel has a video where my research on this type of solar heater is described in more detail. The link to that more detailed video is • A new type of mirror s... , and it describes not only similar experiments in other months, but also other information and ideas on the topic of my research on the 3rd type of solar heaters.
My research comes to the following main conclusions on this 3rd type with motionless mirrors in comparison with this 1st type with turning mirrors.
1 sq.m of mirror of the 1st type produces more heat than 1 sq.m of our 3rd type. Comparison of their heat production is described in that more detailed video, and usually the 1st type produces about 2 times more.
But on the other hand, our 3rd type can be several times cheaper, and our 3rd type becomes economically viable if its square meter is at least 2 or 3 times cheaper than a square meter of mirror of the 1st type.
In addition, we come to the conclusion that the 3rd type requires a super-cheap kind of mirrors, and now I am testing several kinds of super-cheap mirrors. For example, it can be primitive concave mirrors made of cheap reflective film, or it can be such a mirror balloon. In addition, I constantly test similar mirrors based on expanded polystyrene, and recently I started testing different kinds of mirrors based on cheap and long-lasting concrete.
On the other hand, if you want to use some beautiful and expensive mirror, I recommend you to forgo our 3rd type solar heater and use 1st or 2nd type.
So, I repeat that the link to my more detailed video about my experimental and theoretical research of the 3rd type is • A new type of mirror s...
Why move anything at all? Just have a long tube parallel with the travel of the sun at the apex(it would not be a straight tube as the more North you go the more the Sun travels on a curved path). You would need to alter the altitude of the tube as the Seasons progress. If heat hits the flow of coolant in the tube at all hours of the day, you still get the same amount of BTU put into the tube as if you chased a smaller area all the time. Zero moving parts :-D
Hi, first of all, as many others wrote: I am super happy to see/hear you alive and well!
From operational/maintenance perspective: To be honest, this 3rd type is interesting as I would think that besides it seems to be indeed cheaper to build, leaving the mirror motionless I would guess it will be a bit more easier to calculate wind erosion effects as there's one less factor (the turning grade of the mirror) to calculate with - and this can come handy when trying to determine the lifespan of the mirrors (also fixed mirrors can be more resilient to stronger winds, and even adjusted to find an optimal angle to the sun's path while finding an optimal angle to have minimal force impact of the ruling wind directions.
So to sum it up: it seems to be a great idea! I hope you can research it further! You are a true inspiration for a lot of us here!
Great to see you still posting videos. Take care. Slava Ukraini!
In the book "Solar Heating and Cooling" Engineering Practical Design and Economics. On page 89 through 92 they evaluate this type of design. Helpful equations fox max Design. Good video.
I'm so glad to see you films. May you continue to make your experiments with cheap solar receivers and keep safe!
Dear Sergiy Yurko,
Thank you very much for your video.
WOuld you please tell me what kind of "cheap reflective film" you used for it? Where can I buy this "cheap reflective film" ?
Best regards,
Carlos
Very cool or should I say hot concept. But not sure how it's better than Parabolic trough . If the parabolic is better than a trough, could you use a water pipe across and eliminate the need for motion?
good idea
the trough linear parabolic would only need to be moved with the seasons
Sergiy it is wonderful news to see you are still with us. We hope you and your loved ones stay safe during this difficult time. How do you propose these moving mirrors to move independently?
he had a previous videos where he used a water pump and a coke bottle to fill it with water and change the angle, very simple and very effective.
Good to see that you are still alive! Love your videos! Technically, one could 3d print a big parabolic shape, and use it to cast (or with some other method make) really big mirrors with the exact shape and size that you want (with the idea being that you only need to print it once per X amount of mirrors). This does kinda break the whole concept that anyone can make it... Perhaps one could make a mirror by making a ring shaped object, with 2 layers of plastic on either side, and pulling a slight vacuum on it?
Quick question, great to print the shape for stated purpose. Please express thoughts on the reflective coating next step in all pertinent aspects. I ask because I have a few ways to form the shape which some folks might do easily. One being old light fixture dome finds. Industrial ones an be a meter or more in diameter. Hopefully the shape of the curve can be adapted.
Drawing a parabola is easy…simple math. Then there is the question to answer in how many dimensions you want your parabola. 3D focuses to one point ideally, but when keeping things simple in 2D, you only need a sheet of reflective material bent to the parabolic function of your liking, and this will focus to a line. Which may be practical: you may place a duct there through which you have the medium flow that you wish to heat.
@@Calligraphybooster it’s not the parabola but the choice of reflective material and it’s adhesive
@@marcisaacs9407 yeah… and both reflectiveness and focus are factors to efficiency. When building cheap, one can be substituted for the other to some degree, or rather make good for the other. When it comes to the reflectiveness of ‘chrome’ powdercoating I suspect the manufacturer has a factsheet on that, just as they have on glossiness.
My preferred material would probably be aluminium foil for kitchen use.
Use the balloon mirror as a casting in sand, spray sand with epoxy, lay on squares of silvered mylar
You can use a fixed linear collector (tube and/or vacuum tube) that will need only seasonal adjustments up/down but not daily tracking...
Semi-cylindrical
Maybe parabolic section?
Beautifully presented ideas... and you put these ideas into practice.
Quite fascinating and informative. Thank you!
Glad to hear you are okay 😁
I wonder about combining this with a simple dirt heat battery... ie heat up the ground, with the water flowing around the thermal focal point. Then pull the heat back out at night!
I like your channel. I hope you do well
I have a telescope. Big 10" with two mirrors. This could work for solar heater
Interesting approach. With the receiver moving does this complicate the piping necessary to carry away the heated fluid? It would have to be flexible would it not? So. Could it not be possible to put a second mirror at the focal point that directs the light to a stationary receiver on the ground? That would make things simpler to construct.
Glad to hear you are well. God speed.
Sergiy, what are your thoughts on Fresnel reflectors? Do they have potential or are they an overrated gimmick?
"NASA used an expensive pen to work in space. Russians used a pencil." A somewhat urban legend but shows that simpler can be better.
Is it possible to make 3kw system by using concave mirror?
Wonderful idea! That is the definition of thinking outside the box :-)))
more people should watch your videos they are the best
Hello, Mr. Yurko;
Thank you for all you do.
I'm very interested in practical uses of solar reflectors.
I've subscribed to your channel,
I really appreciate you speaking English for our benefit.
I've got 2 small satellite dishes, space blankets, & adhesive reflective material (mirror-like).
I'd like to see you make the fence mirror w/ measurements.
I'm sorry for the issues affecting your country.
Bad governments & bad governance are global issues.
They will soon be gone forever.
I wish you & yours the best.
Have a GREAT day, Neighbor!
This reminds me of a Campbell-stokes sunshine recorder (a sphere of glass that acts a magnifying glass and burns a line in paper to show the length of time the sun was above the horizon). I wonder if a simple version could be made which puts out enough energy to do work, as it needs nothing to track the sun once focused? Just an idea.
SUPER GENIUS. You should be REWARDED and CELEBRATED. Amazing Creative. Thank you....
Xin cảm ơn đã chia sẻ với khán giả mô hình tận dụng năng lượng mặt trời rất tuyệt vời
4th type, no moving parts, parabolic tray or tube, can factor reduce movement of sun to stay within focus on stationary target.
What about a stationary Fresnel lens? Maybe difficult as a DIY project, but doable in volume
The latest and best solar concentrator to date was presented by Padre Himalaya at the St. Louis Fair in 1904. His pyrheliophero developed a heat of almost 4000 °C at that time and received two gold medals and the grand prize for it. This is an achievement that no one else has ever accomplished.
Stay alive my friend. Let the fight pass by. But stay put. Politics will always be politics.
There is even a 4th type, where both are not moving! The heated pipe has to follow the curved path of the reflection. ;D

This is actually there FIFTH type. The earlier fourth type described the second mirror (moving) directing the heat or light to a stationary receiver.
3rd type optimizes for midday. A semi-circular array with receiver on a different pair of pivots (vert.-equatorial axis), might be able to adapt for better production for morning, evening hours
Love your videos!
There is a 4th type that has no moving parts at all. If you use a stationary secondary mirror or mirror segments placed in the path of the main focus to redirect to the boiler.
more expensive initially ... I imagine the maintenance cost would be lower ... so in the end, it would probably be most cost efficient.
The barrier to entry will always be the prime mover. You can't build what you can't afford to build. His video is a position within that tradeoff, although he doesn't seen to entertain that aspect. Another limit consideration is the available space and efficient use of it. Quite often it's a tradeoff that is more difficult to run the numbers on than we think. Weight will certainly be a consideration as well as durability ... weather and the ability to build on top of other things will increase or decrease the available space and what you can get out in terms of where you can put it. I can't list all the considerations as I do not know them. I tried to mention the ones off the top of my head sorta speak though.
good to see your posting!!!
Only works effectively with direct sunlight, but it's actually more efficient than pv cells. I like your design, it's very clever.
The scary thing about Type 2 is the initial positioning of the mirror - you don't want it shining into your car as you are driving past. The tracking is complicated and what do you do if there is a big cloud drifting by - how do you acquire the sun and ensure that you don't steer the beam where it endangers someone. With a Type 3, you could probably just control it with clockwork mechanisms. There is a Type 4. Both receiver and mirror is fixed. It is very difficult to make simply and is known as a en.wikipedia.org/wiki/Winston_cone .
Your pretty snow covered, peaceful Ukraine.
Slava Ukraine 🇺🇦
Thumb up and Sub
🤙
i saw a large scale powerplant in video of isreal where same technology is used to convert water to steam or heat oil then stored in a tank or underground.
Amazing....
I've had an interest in this type of solar ever since I saw one in Mother Earth News Magazine back in, I think, the 1970's. The gentleman used 100 one foot flat square glass mirrors aimed at a single collecter. One thing I still like about his was, it could allow air to go through, so not be like a big sail, but the boom had to be, I think, around ten feet long. I have alot of ideas in notebooks and after seeing your video, will prob be making some more pages in a note book. Some day I hope to make one (some). Thanks for the info and prays for your safety.
My father actually made one of those in the late 70's in Williams Oregon. The unit itself worked well, but the boiler (being at the top of that 10 foot pole) had to be very light and so tended to degrade and leak. Also, steam engines are very high maintenance. He was working on a turbine, but never completed it.
@@JamesNewton I think a Tesla tuban would've been a good fit for it. He desighed it because they were high maintance. Also, all that glass had to weigh alot, over a cubic foot of glass if normal 1/8" each. It sounded like it should have produced alot of power. In the magazine, he didn't have it running a generater yet and never saw a follow up on it.
Great to see you post videos!!! Your ideas will come in good to help Ukraine rebuild again!

Hello sir this method of project heat transferred to be converted electrical energy.
I have understand but already induced this methodology.
sir one problem sun rays meeting and all ray meeting focal point should be convert by heating transferred electric energy.
Device. Name ..focal point.
Serhiy you have a Ukrainian surname have you tried Onipko rotor system for wind turbines, this Onipko a Ukrainian scientist and inventor solved the wind problem his design is able to harness energy at 2 meters second while conventional wind turbines need above 8 meters per second go and look up .
In the second type I thing the mirrors are parabolical, but they are a offcenter slide of a parabola. Maybe this gives the receiver a more constant concentration factor all day long. But yours is much more clever. Just move the easy part, not the big one. Much more cheaper to build
Hi,
I suggest you watch the fixed focus system in the video below
ruclips.net/video/r0pr9fc1weU/видео.html
If you have a stationary trough mirror, the receiver is linear and only need move up and down. And the shape of the mirror is even simpler - just a long concave channel. (I did not originate this idea.)
Do your motionless mirrors have the same parabolic shape as moving mirrors or do you have to adjust the shape for a moving receiver?
Nice paint job.
stay safe brother great video +1 sub

Michel G Rabbat:/Egypt.-Amer./Florida Keep alive dear Serge..I am trying to set up a Charity in Egypt..if I succeed I shall cover the cost of your work to Egypt...so you can help rebuild Ukraine when the crazy war ends..I encourage using a group of fresnel cells rather than your wonderful mirrors...you would then need small mirrors only and recover heat / or cold as you need. May God save us from those who want to control others...out of stupid mania...
There is another type. A poarabolic shaped long reflector. Your collector runs down the focal point of this long sheet that is bent into a porabola in one of its dimensions.

Friend hope you are well and able to carry your research in Ukraine.
Great job when it will available Globaly thanks ❤
Good idea to move the receiver instead of the mirror .The only issue I see with doing that is having flexible hoses that can work under extreme pressure and temperatures
What pressure? You move enough coolant through to not allow it to boil. But yes, that is a simple task. Use pressure washer hose from those diesel heated washers. Would a 5,000 PSI working pressure be enough for you? :-P
@@leofortey7561 those do work but the only problem is going to be how many flexations before you have a failure .,the other issue is coolant type ,Mercury ,oil ,glycol ,water salt mixture.It needs to be something that can hold alot of energy and then your heat exchanger design ..I wonder how much of the 1kw/m2 we can scavange.
I'm not sure if this approach would work in really windy climates. Seems like the moving collector would be more subject to damage than the 2nd option. Maybe cylindrical mirrors would be the best option where they'd only really need to be adjusted daily (or even less) and be able to deal with the sun's movement from morning to evening
It would be better than big movable mirror, the wind pushes that more because it has more surfce area. You are thinking that because his model is made of wood it would move more, which it would, but it could be made of metal which is much stronger.
@@mookfaru835 Fair point, I guess I just thought that you'd have an easier time shielding the mirror than the collector but forgot that it'd be physically larger and thus harder to work with.
@@beskamir5977 Yea try moving a large sheet in the wind, it will blow you away.
What if a mirror was designed to reflect sunlight at a target, so that because of the shape of the mirror, there was always an area of the surface which pointed at the target? This could mean neither the mirror or the target moved. There would be a loss of full utility of the mirror, But the benefit would be that no machinery or tracking device would be needed.
Seems the competition for your 3rd type would be Parabolic trough system or linear freshnel systems, the main advantage is concentration of the light to a point rather then a line which could reach higher temperatures then linear concentrators.
Thanks Sergiy for the video and updates, God bless
cok guzel başarılar
Did you use a storage medium like Salt?
Actually gave me white out from just the video of the sun reflection, lol awsome information thank u for your great insight
Some of these heleostats I have never seen before. If you know the various manufacturers could you please let us know who makes them?
Make text transparent hence we can see the images clear
I am very glad, have see you work.
I think you had a good idea. Make it even cheaper if it is moved by ropes. Computer controlled it can move so many ways.
Can we use very slow motor to move them horizentally and vertically
@@lawand11klose the type of electric motor is irrelevant, they all do the same thing. in the wind it wouldn't work. But i see why he wanted a rigid mover, because the pipe connecting is the one that holds the hot fluid.
avoiding electronics entirely would be ideal, a mechanical computer could be 3d printed
Not new been around for 40 years
I am so happy to see that you're still there, and that you're still doing your work.
GOOD
Try using a round wire grid to avoid unbalanced deformations of the mirror.
I find that the best and cheapest mirror solution is a sheet of highly mirrored sheet of alumium that you bend in a parabel tube. You have 98 % refelexion and it is hardened. You dont need a mold, because it gets its optimal form by slightly pressure on the two long edges and snapping it in the right position. With this mirror your moving receiver must be obviously have the shape of a stick that is as long as the mirror.
Can paired to movable receiver better and cheaper
We’ll done. Great idea
Looks dangerous for any lifeforms if they pass through the space between the two components.
Excellent work.
Please keep posting
