This is the beginning of my experiments with this new solar heater which contains this row of mirrors on the surface of this earthen berm. This mirror berm is many times cheaper than the concave mirrors for large solar power plants. Investors have already built more than a hundred of the power plants with a total cost of about $ 40,000,000,000

A similar mirror focuses solar radiation into such a receiver, where solar energy is converted into thermal energy with a temperature of almost 400 ºC which are converted into steam to produce electricity. In addition, some of that thermal energy comes into similar heat storages to generate steam and electricity at night. It is obvious that if this mirror berm reduces the cost of those solar plants by several times, the cost of our solar electricity will drastically decrease, and therefore we will win the competition against thermal and nuclear power plants.

We can notice the following 2 major innovations of this solar heater. First, it uses such mirrors which are made of cheap and long-lasting concrete. The 2nd innovation is this cheap berm which is made from the surrounding soil, and now I will try to prove to you the expediency of these 2 innovations.

We usually think that the main parts of such solar heaters are this mirror and this receiver, but here we see that they form only about 40 % of the cost of a solar heater. At the same time, this half of its cost is formed by various structures and devices between the mirrors and the ground, but we get rid of this half of the cost if we replace them with our cheap earthen berm.

It is interesting that the heavy weight of our concrete mirrors turns into an advantage because our heavy mirrors cannot be moved by a hurricane.

Now I remind you that traditional solar heaters must constantly turn according to the movement of the sun across the sky. We replace this movement of the mirrors by this movement of the receiver, and we can notice that this system is many times cheaper than those devices for rotating large and heavy mirrors. Our mirrors and receivers should be located along this West-East line, while the rows of traditional solar heaters are usually perpendicular to this West-East line.

I have to clarify that this earthen berm was built for 50 degrees north latitude where my experiments are taking place. If it were located in the tropics, the berm would have to be something like this, lower and cheaper. The location near the equator allows us to abandon any earthen berm, and we can put our heavy concrete mirrors on the ground.

The total construction cost of the solar heaters for these European and American power plants was approximately 300-400 $ / sq.m. However, these new Chinese power plants use cheaper solar heaters with a total construction cost of about 200 $ / sq.m. The cost of the materials of this concrete mirror is about one hundred times less, about 1.5 $ / sq.m, and this is the cost of its materials.

Of course, we understand that we must add other costs for the manufacture and installation of our mirrors, and the costs regarding this earthen berm and this receiver. But still the total construction cost of our solar heater can be many times cheaper than traditional ones, especially if someone makes a machine that will build an earthen berm and put concrete mirrors on it.

Let's look at how I made my mirrors with my own hands, although we understand that we should have an automated production of our concrete mirrors, similar to factories for the production of such well-known concrete products. The making of my mirror began with this reflective film which was temporarily fixed with moisture on a curved surface. Then I put the 1st layer of concrete which is composed of sand with a large proportion of cement. After a short wait, about 1 hour, I put the 2nd layer of concrete from sand and gravel. The 2nd concrete layer must be reinforced, and I did the reinforcement not with similar steel rods, but with this polymer fiber.

Let's look at how my concrete mirrors focus the sun's rays on this white screen, and this is a spot of solar radiation from my mirrors. We can notice that the height of the spot is about 10 times less than the height of the mirrors, but we have seen that I made my mirrors badly, and maybe someone will make them better so that the spot is several tens of times smaller.
