The world’s cheapest solar heater 300 ⁰С: its problems & their solutions, new experiments 2024

This concave mirror is made from this reflective film at a cost of 25 cents / sq.m, and this mesh of steel rods with a total cost of about $3, and it is almost 100 times cheaper than these mirrors which are used to convert large amounts of solar radiation into thermal energy and electricity, and we understand that the radical reduction in the cost of these mirrors makes their electricity cheaper than from solar panels, or thermal and nuclear power plants. You may think that these cheap mirrors do not work well, but it is not, and my old videos showed how that mirror focuses the solar radiation here, where it can heat up to temperatures higher than 300 ⁰C. In addition, my old videos repeatedly showed how we can turn this thermal energy not only into cheap electricity, but also into very cheap heat for greenhouses, for industrial processes, and for district heating of a city. Of course, you may ask, if this device is so wonderful, why has not it made a breakthrough in electricity generation ye
