Generation of solar electricity 24 hours a day, regardless of the weather and season.

We know that solar panels provide little electricity in winter due to a lot of cloudy days and snow, but this video will show how similar solar heaters can overcome this shortcoming, and our solar stations can work just as well in winter as they do in summer, in addition to our ability to generate electricity at night, on cloudy days and other advantages over solar panels.

I am quick to point out that these mirrors focus solar radiation which produces very cheap steam, and I'm testing different types of solar heaters to find the type that will give us solar thermal energy at the cost of 0.5 cent / kWh, and it is about 10 times cheaper than the cost of heat from natural gas. These cheap solar heaters should replace these very expensive mirror structures whose long rows form such large solar power plants covering an area of ​​several square kilometers, and forecasts for the development of similar mirror power plants can be like this, where now the annual turnover is several billion dollars, but it could be tens of billions of dollars in a few years.

These expensive solar heaters have mirrors that focus the solar radiation into this receiver, where the radiation heats thermal oil up to 400 ⁰C. The hot oil is transported to the center of the power plant, where a proportion of the thermal energy of the oil produces steam for a turbine with an electric generator, and the rest of the energy of the oil heats tens of thousands of tons of substance inside these heat storages to a temperature of almost 400 ⁰C, and this thermal energy produces steam for the same turbine during 6 or 10 or 15 hours in the evening and at night.

It is obvious that an increase in the volume of our heat storages by several times will increase the reserve of their energy for several tens of hours of operation of the same turbine which will now receive the energy from the storages not only during the coming night, but also for several cloudy days in a row.

But let's additionally increase the volume of our heat storages by several tens of times, and the substance of these heat storages will be heated during the summer months, and then they will store the thermal energy for several months to provide the energy to the turbine during the cloudy winter months.

Thus, our solar power plants become independent of weather and seasons, and they will be able to produce electricity in winter as much as in summer. This is the 1st example of gigantic heat storage for transferring large amounts of energy from summer to winter. It was built 15 years ago, and the heat storage is the soil inside these dimensions, and let's see how it is operated in this town in the southwest of Canada.

The town has a large number of these solar collectors. The collectors convert solar radiation into heating a heat transfer fluid which goes through pipes inside these boreholes, and therefore transfers its thermal energy to the surrounding soil. This heating of the soil occurs during the summer months, and the soil temperature reaches 80 ⁰C in September. This thermal energy is stored for several months, and then it goes to the district heating of the houses in this town. That is why usually 100 % of the heating needs of these houses are covered by solar energy from that soil and from the solar collectors, although sometimes, but very rarely, they use natural gas. Now I am showing how the Canadians quickly built their heat storage, during several months.

Unfortunately, the Canadian heat storage loses a lot of thermal energy through the soil and a little energy through this thermal insulation which consists of a layer of this material 20 cm thick and a layer of soil about 1 m thick, and now I am showing a green lawn that covers the heat storage. These heat losses take about 50 % of the useful heat during the 6 months of autumn and winter, but these percentages can be drastically reduced, for example, we know that increasing the volume of a heat storage by 1000 times reduces those percentages by about 10 times. Approximately these large heat storages for several million cubic meters of soil, is required for our solar power plants to transfer a huge amount of thermal energy from summer to winter.

But our solar power plants will heat the soil up to several hundred degrees, and therefore we have to make some small changes to this Canadian heat storage. For example, Canadians use these plastic pipes in those boreholes, while we should use metal pipes. In addition, our large heat storages may have similar problems due to groundwater, and let's look at other types of heat storages which do not require drilling expensive boreholes up to several hundred meters deep.
