Its efficiency? The world’s cheapest solar heater of Parabolic Dish type

Many people will be surprised, but this cheap reflective film has been working for about 2 month in wind, rain and snow. These are my experiments to create a solar heater which is 50 times cheaper than similar parabolic mirrors for the production of solar electricity. My cheap mirror is designed to convert solar energy into thermal energy for liquid with a temperature of about 300 ºC, which will produce electricity similar to these well-known solar power plants. We know that these power plants can generate solar electricity not only during the day, but also at night, thanks to a similar heat storage, and therefore they are better than solar panels which give us electricity only during the day. The goals of my future solar heater are described by this formula which leads us to the cost of solar heat at the level of 0.5 / kWh, and it is approximately 10 times cheaper than the cost of heat from natural gas. In addition, this cheap thermal energy can be used to generate solar electricity which is chea
