Its total construction costs are several dollars per square meter

Now I will show the cause why this solar receiver can produce high temperature heat.

Here we see very cheap primitive mirrors which focus solar radiation on the receiver. Now I show those mirrors, and we see that it is a cheap reflective polymer film. This is the spot of solar radiation from the mirror in the winter, when the sun is low above the horizon. Of course, the focusing has poor quality, but this is not a big problem if we use a wide receiver as on my solar station. Obviously in the spring, the sun height increases, and therefore the spot is located in a different place if we refuse to change the vertical angle of the mirrors.

Here we can observe how the wind worsens the focusing. In addition, we understand that wind can be a problem for the lifespan of our cheap mirrors, and I will describe the solutions to this problem in a few minutes.

So, I made these mirrors from this reflective mylar film which was bought at a price of 20 American cents per square meter from one of the Ukrainian manufacturers. It is about 1000 times cheaper than these mirrors of modern solar power plants.

My idea is to build such long rows of such cheap mirrors. Of course, we need a cheap receiver which will be located in the focus of our mirrors, and I plan to test 2 versions of the receiver. This is the first version, and I described it in one of my old videos about a month ago. The second version of the receiver was described by my 3rd YouTube channel, and its link is below. I remind you that my mirror systems do not need to change their position from morning to evening, and I described their capabilities and features in some of my old videos.

In addition, I plan to explore the second variant of cheap mirror which has this additional cheap polymer film. It is obvious that the additional film helps the mirror withstand strong winds.

However let's look at the first variant of my mirror, without that additional film. We see that the bottom edge of the mirror is not fixed, and the weight of this structure can make the mirror have a minimum of wrinkles.

Now we can understand that the mirror can be easily and quickly removed or installed, and this is important if we plan to use our mirrors for several weeks or months per year, for example, for heating a greenhouse only during March, or for space heating of a house from November to February. In other words, we can remove our mirrors at the end of the heating season, and therefore the lifespan of our short-lived mirrors can reach several seasons.

We understand that these wires provide our mirror the desired shape. Now I show that I used different types of the wires to find the difference between them. But we see that any difference is missing.

I have to do long term research, during which I will wait for the mirror to be destroyed by a strong wind to find its "weak point". For example, this incident helped me find another “weak point” here. This is a new mirror, where that "weak point" is reinforced.

It is obvious that winds must destroy some more of my mirrors so that I can find some more "weak points" and strengthen them. After finishing the research, my third Youtube channel will describe the final version of this type of cheap mirrors which will be able to withstand strong winds.

Of course, we have the opportunity to temporarily remove the mirrors before hurricane, and I remind you that my second version of the mirror has more ability to withstand strong winds.
