New generation of this type of solar heater

- 7 years ago I built this solar station, and almost a year ago I decided to create its next generation which I am testing with this prototype. This prototype should eliminate several important disadvantages of these old solar heaters.
I spent less than $1000 building these solar heaters with 58 sq.m of mirrors, and we can calculate that it is about 15 $ / sq.m. So, my solar heaters are about 20 times cheaper than these heaters which focus solar radiation on such receivers. We know that these expensive solar heaters are the basis of very large solar power plants, and the value of all these plants now is approximately $40,000,000,000.
Now I remind you that these expensive heaters must constantly change their vertical angle according to the movements of the sun across the sky. Similar changes of the vertical angle are missing in my cheap solar heaters because they are located along this West-East line.
Now I am showing photos of this spot of solar radiation from absolutely motionless mirrors at these points in time of one day from morning to evening. The movements of this spot lead us to the idea of adding a mechanism for small changes in the receiver position in these directions.
That is why my new prototype has these springs, and I want to add a very simple and cheap system for changing the weight of the receiver. Now I am showing an example of our simple and cheap system, and these are containers for water. We understand that the more water is in the containers, the lower our receiver will go down.
Unfortunately, this type of our simple and cheap system has several disadvantages, and therefore I am planning to change its design. Now I am starting to show one of the disadvantages. We see a large water leak through the top of this container, because the water comes from this second container. This movement of the water leads to an imbalance that we can see because of this slope. Increasing the imbalance increases the movement of the water, and this phenomenon increases the imbalance even more. This disadvantage says that we need a different design of the receiver weight change system which should be simple, cheap and with a long lifespan. I have some ideas for new design of the system, and I will test and describe them in my future videos. Now we will see that here the water leak stops, because the second container is already empty.
Perhaps you think that these springs will rapidly aging, degrade and stretch. That is why I did the following testing, and now we must notice that this level is at a height of slightly more than one hundred centimeters. It was in the middle of January, and then several months passed when the position of my device has not changed. Now I will show the condition of my springs 4 months later, and here we see that my springs did not degrade and did not stretch. The springs were from this very cheap Chinese sport expander, however, we see corrosion of my cheap springs after 9 months of outdoor use. Perhaps my future videos will describe solutions, what to do if our springs stretch, and why their lifespan will be several decades.
So, I repeat that I will be making new videos on this solar heater, in parallel with testing it and improving its design. My goal is to reduce the cost of its heat to the level of 0.5 cent / kWh, and it is several times cheaper than cost of heat from natural gas or coal. In addition, our cheap solar heat with a temperature of several hundred degrees can be used to generate very cheap electricity in a similar way to these solar power plants.

As a fellow backyard technologist, I applaud your efforts to make solar energy cheap and accessible to everyone! Big companies have no incentive to bring costs down because it hurts their profits, so it is up to people like us to make innovations like these so they can benefit everyone.
Well done!
Thanks for the info.
Great channel.
Very nice I look forward to you future vids Thank you and Peace
Great Job as ALWAYS🌄🌅🌞
Ingenious!
Simply add a string to each bottle arm up to a pulley system which has a reversing crossover string to the other side. Therefore, if one side goes down, the other must match it, forced by the pulley system.
❤ whaooo! So nice! ❤
Suggest add extra string with little slack on the spring so you can set a max depth of spring will stretch, in case a Cat jumps the side or if one spring fails it will still protect system.
Also as a user below has stated a pulley system is a good idea to maintain balance.

Could you use a strip of material above the target that expands when heated and a strip below the target and attach each to a cable and string pair (so 4 springs total) to adjust the target up and down automatically to keep the light centred on the target over the course of several months?
Why use spring? is it because you want the receiver to move randomly? how does that track the sun?
eg, 12.38 is noon and thats when your receiver gets the most direct sun, if receiver moves around then it will get less heat.
sun rays are strongest around noon.
14.18 is when your receiver gets about 30% refection
This is absolutely amazing! May I ask where you are from?
Ukraine..his country is getting bombed and he is still putting up content.
can you make setup that converts salt water ? that would be realy intresting fore alot of peopel
How did you curve the mirror?
are your family ok, mr yurko??
Hi Sergy, i have 2 concerns.1 high wind,2 Hail damage.
i think solar is most important in the winter, so maybe concentrate on your designs that are not affected by freezing temps.
