- 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.

I much prefer your real voice to this emotionless computer reading, Sergiy.
Yes, it is easier to follow.
Yes
I agree Sergiy we will miss your voice. Thanks for your video though. It was back on track when you were telling us about the Canadian heat store 😊
Yes me too, your enlish is prefect
the necks hurts
I really do appreciate your natural voice. Your ukrainian accent is like a part of your brand, something that distinguishes you.
I think, he could use his natural voice and just also provide a (complete) written transcript for the hard to understand moments.

His English is perfect. I prefer the natural slavic accent.
I prefer listening to your natural voice Sergiy. You are very smart. Thank you for this information.
This is a brilliant culmination of the research you've done for the past while. Here's hoping we see something of a scaled-down prototype at some point. Great work.
I love this content it's absolutely the way forward. Please do look into Sterling Engines as a means to produce electricity very efficiently from any thermal heat storage. Much more convenient and cost effective than a steam turbine. Hoping to run my off-grid build using solar collectors, a sand battery and a sterling engine. Great work thank you
So 1 btu is 1 degree change in temperature of 1 pound of water. To heat a tiny house over night I need 20472 btu. If I heat water from 80 to 180° that's 100 btu per pound. I need 204 pounds or 25 gallons water.
If using sand where 1 degree per 5 pounds is I btu I can heat to +300° then it's 1500 btu per 5 pounds. I need 342 pounds of sand or around 27 gallons of sand. This is very doable! A 50 gallon drum insulated with cheap foamed cement or AirCrete will do it!
This and heat pumps could be enough to kick start a long term energy storage industry. I'd go as far as that maybe shipping super heated fluids might be commercially viable.
Yes, you are talking about a very important topic that everyone is keeping silent. It is impossible to make the energy transition to solar energy without seasonal energy storage. Now there are power plants with a capacity of thermal or electric batteries up to a maximum of about 15 hours. But this is for Africa or for California. In all other regions, the sun may not be for weeks. Also in winter in our region there is about 10 times less sun than during the summer, so you need a battery with a capacity of 3 months instead of 15 hours. That is 144 times more than it is now. With electric batteries, this cannot be done cheaply. Therefore, I agree that giant thermal batteries made of sand or stone are the best choice
As of my view, main issue is the turbine. If we will not be able to obtain effective one, everything else will go in vain. But I see You invested pretty much time into creating this video, good job, hats off.
I used chat gpt to do some thermal battery calcs, it's pretty good, makes some mistakes so you have to babysit it, but it's still very helpful.
Why don't u try out thermochemical storage system? It's much better than sensible or latent heat storage. Zeolite or Calcium carbonate based
Thank you for this content. I am from Egypt, and it is a sunny country most of the days of the year. I am interested in experimenting with using mirrors to generate solar energy, but I have a problem designing receivers. Can you help me? I want to know the materials that you used.
Check out his videos on this channel, he mentioned different designs and material selection
По идее, можно обойтись без труб. Можно заполнить огромную яму камнями и залить маслом. Нагретое масло из солнечного коллектора надо подавать сверху, а холодное масло - откачиваться снизу и подавать обратно на нагрев в солнечный коллектор. Ещё можно использовать керамические трубы, потому что они лучше проводят тепло.

Greetings from the north of Sweden (close to the polar circle). I am curious about the oil used in these high temperature applications. I am planning a seasonal insulated under ground sand storage myself. I have tried to find the right type of oil but have trouble finding it. Not a thing the average Joe is supposed to play with i assume...
Здравствуйте Сергей, скажите пожалуйста, а масло которое используется в данной системе и нагревается до 400 градусов, это какое то моторное масло или масло из силовых трансформаторов?
Dzień dobry⚡ 🔥💪
i'm having trouble sourcing lower cost polished metal sheet , locally, (Colorado)
What if we do not have hot water/ heating requirements?
If all we need is electricity generation, will a steam turbine be more feasible than a thermal oil?
What is a good liquid that can handle high & low temps, & stay a liquid? I'm thinking -60°C to 400°C.

Orient The colector in the Polar star. And not with water, but with grafit powder in a serpentine in send tanks.
Stiesdal proposed a thermal battery based on rocks with heat transferred by air. This can reach higher temperatures but should work with solar steam as well. The main difference is that it was insulated by mineral wool and steel plates.
I wonder now with the more DIY Ultra White Reflective paint, where Nighthawkinthelight and Tech Ingredients youtube channels show how to make, how the reflectors can be improved? Might even be able to cool the buildings behind or underneath for hotter summer conditions? To be able to use that paint, my thought is some sort of Fresnel Lens cover that can be more easily washed with maybe a pressure washer along with having the higher surface area to focus more light on the reflector.
Water waves can also be used to generate electricity so renewable sources of energy are only limited by human imagination.
Nice but I like your normal voice :(
