- This is the 1st example of our idea, and these mirrors direct solar radiation to the top of the tower where the radiation is converted into thermal energy to produce steam for a turbine. The efficiency of turbines is only a few tens of percent, and the remaining 60...80 % of the energy is thrown away, but that power plant does not throw away the heat, but directs it to these greenhouses for their space heating. It is obvious that sales of the heat to greenhouses provide additional money which can radically reduce the cost of electricity from similar solar power plants.
Unfortunately, the heat sales in the case of this Australian power plant reduce the cost of its electricity by only a few tens of percent, but this video will describe two methods of connecting a greenhouse and a turbine, which reduce the cost of electricity several times. That is why the following two methods lead to the fact that our solar electricity becomes cheaper not only than electricity from thermal and nuclear power plants, but also cheaper than solar panels, especially in Europe, Canada and the northern United States.
We understand that this is not the only type of mirror systems, and now I am showing other types of mirror systems for generating electricity, without any tower, and they can sell thermal energy to greenhouses too. In addition, my RUclips channel studies cheaper types of mirror systems that will suit us even more.
One of my old videos described solar power plants consisting of a large number of mirrors which produce a lot of solar thermal energy to heat a large mass of soil through pipes. The heating of the mountain occurs during sunny summer to a temperature of approximately 300 ⁰C, and then this thermal energy is stored for several months so that we can use it to produce electricity during the non-solar winter.
This outer layer of soil, several meters thick, serves as a thermal insulation, but it is obvious that some of the thermal energy will be lost due to heat leakage. That my old video showed the results of calculating the heat leakage for the case of an artificial mountain with a volume equal to 4 pyramids of Cheops and such dimensions. It was found that 7 % of the thermal energy of the mountain will be lost through its bottom, and another 8 % will be lost through the top and sides of the mountain.
Many of you have already come up with the idea to place a large greenhouse here, and especially interesting is the location of greenhouses here, on the southern slope of our mountain. We understand that such greenhouses will be heated by the heat leakage and other options which will be described later. Unfortunately, the surface area of our artificial mountain is not large, and therefore most greenhouses should be located not on the mountain, but around our power plant, and they should be heated according to the 2nd and 3rd options.
The 2nd option for heating greenhouses occurs through these pipes on the periphery of our mountain, at a depth of several meters from its surface or several meters above this groundwater. The greenhouses are heated by warm water which circulates between these pipes and greenhouse heating pipes. It is interesting that the heat extraction through these pipes reduces the temperature of the periphery of our mountain, and this phenomenon leads to a decrease in these heat leakages to the outside of our mountain, although it increases these heat flows.
The 3rd option for heating greenhouses was described at the beginning of the video for the case of this Australian power plant, when the warm water for greenhouses is heated by condensation of steam after the turbine. The 3rd option covers about 90 % percent of the heating needs of greenhouses according to approximately this graph, where the maximum heating is during these winter months, but these autumn months and these spring months also require a small heating of the greenhouses.
This is the production of the electricity during 12 months of a year, and we understand that this part of the thermal energy is emitted into the atmosphere. It is obvious that this part of the heating needs of greenhouses is covered by the 2nd option, that is, by the heat from the periphery of our artificial mountain.
It is interesting that the production of our solar electricity during these summer months is slightly less than during these winter months. It is a radical advantage over solar panels which have such a winter dip, 7 times less in winter in Finland, or 3 times less for Southern Europe.
Great video. Great to see you are doing ok. I hope everything gets better in your country. Thank you for everything you have taught us.
These are really fascinating videos thank you! I've been interested in similar concepts but on a smaller scale for just 1 home. Using your DIY solar collectors attached to a well insulated (perhaps mineral/glass wool) 'thermal battery' (possibly just sand!?) but no idea how to work out the size required for inter-seasonal thermal storage for 1 home. A sterling engine directly attached to the thermal storage could produce electricity and heat would be easily enough extracted to heat the home in winter. Would really appreciate your thoughts and any calculations for this concept 😎
Solare thermal lost to PV years ago. Nothing can compete in economics with PVs. And PVS are still getting cheaper and cheaper.
True for electricity production... But there is a lot of need for low value heat around the world...
How do I heat my house in the winter with solar pv
@@-whackd your options are different depending upon how close to the earth’s poles you are. If you are close enough to the poles that you receive very few hours of daylight during the winter, then it is probably best to set up an insulated tank of sand. You would need to have electric heaters placed equally throughout the tank, and use piped air or fluid to move the heat to your home. The PV system will provide electricity to the electric heaters during the summer months, and the insulated sand will store the heat until winter.
If you live in a region with longer daylight hours, then you can just use the PV panels to power electric heaters to heat your home.
@@justinweatherford8129 Marketing has been a big factor in the belief that solar panels are the thing. When you reconcile all the tangential costs/risks and take geographical location into account, solar panels don’t always make sense. Sergiy’s numbers don’t lie.
@@ThisIsToolman I don’t disagree, but the question was asked about PV panels. Therefore I answered regarding PV panels.
Engineers came up with the idea of storing heat in graphite bricks in a mirrored thermos.
Then this energy can be received back in the form of heat or electrical energy.
Инженерам пришла в голову идея накапливать тепло в графитовых кирпичиках в зеркальном термосе.
Затем эту энергию можно получить обратно в виде тепла или электроэнергии.

If only people and engineers would pay attention wed all be saved.
Fools
Try to make an ice lens while there is winter. To do this, pull the plastic film over the round frame and pour a little water on it. I'm just wondering what will come of it.
Попробуй сделать ледяную линзу, пока не кончилась зима. Для этого натяни полиэтиленовую пленку на круглую раму и налей на нее немного воды. Мне просто интересно, что из этого получится.
The problem is, that, if you are in hot Spain, greenhouses are already hot and you cant redirect that heat there.But in spring, autumn, even winter (that barely has sun)-very logical.
Thank you man
A perhaps new thought is to stack the earth/sand-battery with a compost solution also releasing heat ruclips.net/user/results?search_query=compost+heating+system
The biggest problem is turbine. It's price is big, and its out of reach to an individual, who is not a company.
Australia need more cooling then heating but i think for high Temperature application it's necessary
For industrial purposes, heating is often more important.
"our idea" - sure LOL !
ok let's do it! who do we have to talk to? Let's have Sergiy do his thing - we can all invest a bit! I am IN!
Not aggressively boiled how to control temperature
Those mirror type solar are usually in the desert. Do you need a greenhouse in the desert?
Adding a water resourvour at the top with floating/covering it with solar cells/mirrors. Any run away heat will be absorbed in the water which will be then used for both a blanket over the solid thermal mas(sand/quartz) and running the heat circulation system plus any green houses nearby. In places with high rainfall you can use the excess water for dam like usage.
Machinery/living quaters and storage on the off sun side.
The sun side ground can be shaped as a year long tracker to align the solar capturing for optimal angles.
Yes such a design is indeed very flexible and parts of the systems have already been in operation for hundreds of years.
About time to upgrade it to current knowledge.
Probably a mound a 100m high and 400 wide... It will be worth experimenting with simply using darker materials on the sides not active and reflective materials near them in order to limit the heat loss from the main thermal mass.
Small scale maybe 10m high by a base of 40x40.
Utilize current walipini greenhouse designs.
I'm wondering if the calendar graph that you show, where there is a dip in production around July comes from an Australian source. It's normal for solar production to dip here in the middle of the year because this is our winter.
how do we improve water evaporation process by solar energy for more faster evaporation process?
Also not too much boil take example if we have salty water so we can’t boil water too much so salt quality it should ok
Are there any recommended build guides (such as on instructables) for a DIY steam turbine for residential use?
Wow! Looks nice. You should totally start a startup with all these technology.
