This solar energy innovation is 10 times cheaper than analogues: solar electricity 24 hours a day

- I made (a month ago) this new device for converting solar radiation into thermal energy of 300-400 ºC, which can be converted into electricity. It uses very cheap mirrors (less than 1 USD / sq.m) and is an improvement on my solar station, which was built 8 years ago, has 58 sq.m of mirrors and cost me about $1000.
Its mirrors focus solar radiation and turn it into heating water for space heating this house in winter and heating water of this pool in summer in the climate of central Ukraine.
Many of us might think that this steam could be used to generate electricity, however in fact it is not, and the main problem will be described in the middle of this video. But that problem is solved by this my new solar heater, and I will show how it can create thermal energy with temperatures up to 400 ºC. I will describe it in the last minutes of this video, and therefore millions of these cheap solar heaters can form similar solar stations to generate cheap solar electricity.
So, I repeat that in 3 minutes I will start describing this new solar heater that solves the main problem of these old devices, but for now let's analyze how this old solar station could generate electricity. Many of us may think that here we should install a turbine which will rotate an electric generator, but this is a bad idea, and we have to use another method which is used by solar power plants of this type.
Investors have already built more than 100 similar power plants in various countries, and let's look at how solar electricity is generated by this American station with a cost of $ 2,000,000,000. When the sun appears, its radiation is focused by these mirrors and heats thermal oil inside these tubes to temperatures of almost 400 ºC. This hot oil moves to the center of the solar plant, where a fraction of its thermal energy produces steam for a turbine that generates electricity. The rest of the thermal energy of the oil comes to these heat storages, where the energy heats more than 100,000 tons of molten salt. A few hours later, in the evening or at night, this hot molten salt will produce steam for the same turbine
Unfortunately, these solar heaters are very expensive, and therefore they give us expensive electricity, but these my devices are about 10 times cheaper.
So, here pumps must guarantee circulation of thermal oil with a temperature of about 300 ºC, and this solar radiation must heat the hot oil to even higher temperatures. In addition, our cheap solar heaters must form similar long rows, covering an area of many square kilometers. When the sun is shining, that hot oil must transfer the thermal energy to a turbine and heat storages which were described in this my previous video. Those heat storages can provide the thermal energy to operate the turbine in the coming night, or for several non-solar days in a row, and maybe they can transfer a lot of thermal energy from summer to winter. That is why our solar power plants are becoming independent of the weather and the season, and that previous video described these formulas with such a cost of our solar electricity, which is cheaper than electricity from thermal and nuclear power plants.
But unfortunately these old solar heaters have the following big problem which will be solved by these new heaters. Unfortunately, these old solar heaters are not able to heat the oil with a temperature of 300 ºC , and now we can notice the cause why this is so. We can notice that here the solar radiation from my mirrors is 5 or 8 times the normal radiation flux from the sun.
The compression of 5 or 8 times is sufficient for a good heating power of a heat transfer fluid with a temperature of 100 ºC, or perhaps 200 ºC, but unfortunately the good heating power at 300 ºC is not achievable. For example, these expensive solar heaters can compress solar radiation by about 50 times.
But this new device compresses solar radiation by a factor of about 20 or 30, which should be enough to heat thermal oil at around 300 ºC, and let's look at how this new device achieves such compression of solar radiation.
My old device uses these mirrors, which are a sheet of expanded polystyrene with a cheap reflective film. This is a very cheap type of mirrors, and it uses these materials with a total cost of less than 1 USD / sq.m of mirrors, and it is approximately 300 times cheaper than the total construction cost of these solar heaters. I use the simplest methods to replace my cheap mirrors because their lifespan is 1.5 years. Now I am showing how those mirrors cover a long row of my old solar heaters.
Let's look at the mirrors of my new device, and they are the same, but narrower, with a width of 25 cm. These mirrors form such mirror stripes. We see that 2 narrow mirrors are mounted on these wooden slats, which form the desired shape of our mirrors. - Věda a technologie

I am impressed with your experiments. You have a keen engineering understanding of the problem. Many people experimenting with solar don't seem to understand the true scope of the challenge.
@@_yoko_3630 Come again?
Neither do you if you believe his device can produce power with the sun, he has stated it is a solar device.
@@ossiedunstan4419 maybe you're thinking of photovoltaics? This is solar-thermal.
if you can maintain heat @ 300C you can create steam. If you can create steam you can power anything very simply. @@ossiedunstan4419
@@ossiedunstan4419 Do you know there are more types of energy besides electricity? Heat energy can be more useful in many ways like heating water or your house. Heat energy can also be used to generate electricity if needed.
It is admirable what you're doing during wartime.
when you choose materials for your collectors, you miss an important feature, long service life / durability. These materials should last long time, not being scratched or otherwise damaged by wind, dust, sorms etc.
In previous videos he has explained that 12-18 months cycle of replacement seems most cost-effective. You can make an infinitely lasting panel for 1000 USD/sq.m, but year-lasting panel with 80% of effectiveness of the latter for an insignificant fraction of the cost is the goal of this channel.
@@wwlb4970 Thank you for replying. That is maybe so. But what about the environmental impact. Polystyrol is not the best material regarding that matter. Not only the recycling or dumping, but also during manufacturing of Polystyrol and preparing it for the collector has a negative balance. Tha would counterweight the positive balance. Would wood planks work? What do you think?
Regarding the one year cycle. Material costs are one part of the calculation. But having labor costs each year makes it less cost effective, don't you think? Labor costs are most often the biggest junk in western countries. A bit longer lasting material would be more efficient, i would assume.
@@michaspringphul good points, can't only be for sack of cost/kw.
Cheers
@@michaspringphul Generally, the price somewhat reflects the production efforts and environmental impact - energy consumed, complexity of production, complexity of recycling. Those high-tech mirrors aren't any environmentally friendly, and while polysterene foam or cheap cooking wrap aren't either, the latter are easily collected and recycled, usually becoming shopping bags. Sergiy didn't really insist on replacing them each year, though, effectiveness will decrease, and I'm referring to the previous videos w/o polysterene, but with metal fishnet instead.
Agree on the durability vs enviro cost. Buy in cost can be so high that many people can’t get in. Practical question: do we put our lives on hold for “perfection” or do we accept & deploy “progress”?
“Perfection is an enemy of progress”
Mileage will vary, people have varying limitations or advantages. 👍🏼
Excellent video discussing your updated solar heat energy concentrator. Thank you for Sharing and Good Luck with your continued progress.
Really glad to see you're still able to make content. Stay safe!

This panel can put out close to 100 watts czcams.com/users/postUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.
01:40 и 01:56 В начале удивился, как может температура в 400 градусов растопить соль с температурой плавления 800 градусов. Потом упорно гуглил пока не нашел термическую соль с температурой плавки 260-550 градусов (60% нитрата натрия и 40% нитрата калия). Привет всем альтернативным энергетикам✌☺
For the solar collector, the black metal, is make it from a lot of little pieces of steel about 1mm thick by about 6-12 mm wide, little strips, weld then to together on alternating sides, making an accordion boot, like a zigzag of steel. Using a black oxide finish, or possibly look into other coatings maybe a aluminized coating, anyway, make the collector side look similar to a car air filter, with pleated sections to maximize surface area, on both sides, maybe use a needle scaler to cover the whole surface with pock marks, adding to the surface area, a Tig welder will weld up nicely, without excess filler material, having the pleats going left to right, with the liquid used flowing the same way, this will eliminate shaded spots mostly anyway, maybe design internal passages to pass through the heating surface multiple times! Allowing it to collect as much heat as possible, before going on to dump it's heat, awesome project, and good luck with everything, happy holidays, 👍
Would the kind of heat-resistant paint used for car engines work? or it would peel out rather quickly?
I wonder if a coated car or truck radiator would work?
Sergiy man, I love you. In this crazy world, I love to see a man occupied by his idea. Keep it up!
I have been following your experiments, you are making great progress and I admire your efforts and success, thank you for sharing.
your content is fantastic, please don't stop making these types of videos. I'm based in New Zealand with aspirations of living off-grid a device like with this with a small footprint for heating water would be brilliant
For a lot more efficient hot water storage i would suggest you the setup i did at a friend's ranch. The company who installed the solar heating installation made some mistakes,so resulted in damaging the hot water storage tank because they didn't put an overpressure valve.So they came and replaced the storage leaving the old tank at the ranch. Then i came with the crazy idea to repair the old tank (it was a gasket damaged) and fill the tank with sand and gravel,of course installing some filters inside to avoid the sand to go into the pipes(just like in a pool filter),and i installed the modified tank in parralel with the other one. After the sunset we experimented how much hot water each one would get untill the water output drops at 30 C degrees. Here comes the surprise.We got 5 times more hot water buckets from the one filled with sand and gravel,but if you think about it is logic,because the water is formed by hydrogen and oxigen atoms,so very low density and mass,meantime the sand and gravel contain carbon,calcium and many other heavy elements with a lot higher density and mass,so they can store a lot more thermal energy.(sorry for my bad english,i'm romanian)
Me too!
Excellent work with continuing improvement. Looking forward to the next installment.
You inspired me for a whole suncircle simulation in python and meanwhile i finished my engineering studies... unfortunetly i move away from this sunny site of the island.. however, today i gained a throughly consistant engineers understanding and stuff... and will be finishing this journey when the gods of wealth are more pleasant with me again. : )))
I hope you are staying well and safe.
Very excited to see a new video, and VERY excited to see that you're still able to make them!
Moving the receiver instead of the entire collector is genius.
I happy to hear you again and to undarstand that you are ok.
I think there are not small losses due to the long pipeline route. But respect, huge work, and thank you.
Nice project. Sending regards from Malawi Central Africa.
very nice design. Storing the heat in large oil container might work too, if you heat a 100L of oil to 400degC then it should stay hot for quite a long time. Good luck!
If you put that large oil container in a sand pit and cover it with more sand, the heat will remain for a very long time.
The accent makes it great to listen to.
Car radiator, close side black and far side white to reflect back anything lost through it to other parts of the rad. You should be able to get a small ish one, but it will increase your surface area enough while not inflating the budget so mightily.
GREAT Job! Let me know if your experiments would be helped by gaining access to a different set of circumstances in life. Willing to sponsor!
Depending on the generator modules’ upper limit temperature, additional optical component or waveguide or light reflecting tunnel or reflecting mirrors can be added to reach further concentrations ratios
Very very nice, we had a setup similar to this after hurricane Katrina in New Orleans USA. I don't know how you only spent 1000 USD on this maybe you robbed a few stores but nice setup.
Superb, please keep up your excellent work.
Slava Ukraine! Spasibo, Sergiy za Vašu izobretatelnost! Interesno inogda posmotret na Vašy solnečnye paneli, kotorye Vy delajete. Ja s Latvii i my za Vas vseh perežyvajem i želajem pobedy! P.S. U nas v strane malo solnca no v etom godu posadili podsolnuh - pervyj raz v znak solidarnosti s Ukrainoi i tot vyros 3 metra v vysotu! :) Ja dumaju čto solnečnaja energetika praveļnoe napravlenie no bez akkumuļjatorov/ nakopitelei/ preobrazovatelei ne oboitis. Po etomu u nas vse stavjat elektro-solnečnye paneli v Latvii i v osnovnom vse rabotajut na "setj", bez akkumuļjatornyh batarei. Jesli ja sam budu delat, to budet povoračivajemaja noga i 400W+akumuļjator (eto uže budet dostatočno dļja "off grid" sistemy letom). Uspehov! Gerojam slava!
although moving the target seems like a good fix. Don't forget if you move the target with liquids inside, u will need good sealed joins. İnstead o moving the target u can move the reflextion mirrors as ur mirrors are very light. Ten u don't need sealed liquid joints only some cheap hinges. Also u can use hexagon reflators for better concentration. U can coat the reflectors with liquid glass for log term useing.
Did great job raising our pool temp by 10 degrees in about 6 days. Two of the day had high temps in low 70 and still put out almost 80 degree water.
Quality research. It has great potential when finalised for the service of mankind.
Keep it up, love your informative content ❤
Thanks for your work
Interesting concept Sergiy, are you using your old array just for the pool? because it looks like it could heat water for the bathroom and even heat the house using radiators, have you considered that idea?
I had an idea. How about finding a big round plastic tub and put the mylar on top and create a vacuum. That would form a perfect parabolic form.
Great, Sergio!
Try a parabolic offset antenna, then the heater will not shade part of the mirror
Great work I am aiming to do a solar heater in Portugal.
Thanks!
Love your videos watched them all.
Thank you!
Sergei! Could you use a focusing lens in the receiver, perhaps? 🙄 The kind from overhead projectors and so on.
If you get one large enough to concentrate from the maximum area of the focused light from the mirror, and perhaps even make a gear for the distance between the black heat transfer box and the lens, so the focus is better at different times of day, that would probably maximize the energy collection.
I suppose you could make a parabolic path of travel for the box, and one for the lens in front, so the focused beam from the lens always has the same size on the box. (Perhaps with a piece of energy glass in the receiver box, to keep the infrared wavelengths inside.)
Is it possible to make a path of travel in front of the mirror to always have the same size area of focused light from the mirror itself?
That would solve the entire problem, of course.
Hello Sergei! I was very worried about you, since you haven’t posted videos on your main channel for a long time! Found this channel by accident. Glad you're all right! Unfortunately, I do not understand "technical" English well. Could you add subtitles in Ukrainian/Russian on this channel of yours? With great respect for you and your work, your humble admirer!
1. At winter very high heating lose from collector.
besides mineral wool can be used 1 mm thiсkness glass for other side. Because heat losses(aprox 50% ) higher them glass reflecting loses (10%).
One layer glass reduce heat loses from 50% to 25 %
2.Extruded polystyrene beter simple polystyrene. Because it less desroyed from sun , has no pores, it is stronger.
love your work!
Another possibility for the rooftop is a dish that heats compressed air to drive a gas turbine. The efficiency of a gas turbine goes up with the temperature of the furnace region and the compression of the compressor. The temperature in a solar collector is limited by the melting point of the material at the focal point. If air could absorb the concentrated sunlight, there woukd be no limit to the temperature at the focal point. But sunlight goes right through air. There is a way that air might be used as the collector. A plasma readily absorbs light and many kinds of radiation. If you had a cylinder with compressed air spinning inside and a high voltage electric arc is created across the spinning air, it seems that a disk of plasma would be created by the arc whuch could be used to collect the sunlight at the focus. If one disk does not absorb all of the light, multiple disks very close together might absirb most of the light. The multiple disks might also trap light or infrared that is reradiated between the disks. You could use small pipes and jets of compressed air coming into the sides of the cylinder to create a spinning mass of air flowing towards the turbine end of the cylinder. A compressor on the same axle as the turbine and the generator could supply the compressed air. The generator can also be used in reverse as a motor to start the turbine.
The temperature of the plasma region receiving the concentrated solar might well exceed the temperature inside of a conventional gas turbine and exceed the efficiency which can be over 40%. This would compare to the best efficiencies available from photo voltaic solar cells.
One problem is that it would be very loud. But if the opening to the cylinder was covered with thick glass and the exhaust exhausted down from the roof to a compartment with heavy walls where the turbine wheel and generator and compressor were located it might be very quiet.
Lovely! I am always excited by your work! For the receiver's scattered sunlight: What about a second, smaller mirror surrounding the receiver, to catch morning and evening rays and re-focus them, as well as increasing the multiplication factor, peak temperature? Wide flanges, like flower petals, could curl inwards, to point the stray light back to the center, while the reflectors just next to the receiver are a steep angle, to help focus-in on a smaller receiver flask, I think...
Its hard to understand this systems need more details
@@karlorf2023 Bend the mouth of a parabolic inwards, so that steep-angled light bounces toward the center, too. It doesn't have to be geometrically perfect, as long as it hits some part of the receiver.
Look at his older trough receivers, they use this idea.
@@unionse7en thank you! upvoted!
how you optimize your system while maintaining simplicity is the engineering challenge! I'm a new subscriber! For what it's worth, I am no longer amazed at how much people can accomplish with what we, in the Western World would consider to be less than sufficient tools. I wish you all the best in your work and in your country's struggle against the Russians.
Mother Earth News made the same thing back in the 1970's, (by when it was more than just a advertisement rag), using the square mirrors that were popular home decorations at the time.
Amazing, I hope you're able to help lots of people in these hard times.
🤣🙄
Thank you for the knowledge brave man, slava Ukraina !!!
Do they have to be able to move to track the sun? For the best possible results? Absolutely fascinating work. Very well done.
I watch on your solar station and researches many years) And other researches and analyzing off existing ways to use solar energy . Thanks for yor work!!! I think that low temperature stirling engine can produce electricity esealy from heat producing by your solar station. If we atach 100w stirling generator to warm battery it can produce 2400 w in 24hour that is anougth to cover almost of all needs of small house
Thanks for this man
Great video a bout solar energy. Thanks
Hi Sergiy, is there someone in Ukraine producing the copper pipe/metal sheet sandwiches shown near the end of your video, or where's the best place to get them? Cheers.
I have been watching all your videos, my friend. Good luck to you.
If you have a frenel lents and put it on the focus point you will improve very mutch the heating power.
I hope you and your family are all doing well and wish you merry holidays. Take care.
5:40 Советую положить зеркало набок, чтобы пятно было не вертикальное, а горизонтальное. А приёмником может служить изогнутая металлическая трубка, повторяющая по форме движение солнечного пятна.
this would be the great way to preheat concrete (walkway / driveways) for snow removal. Store pre-heated water reduce fuel (battery) costs over night.
Sergiy. Could your new collector be used to heat a Phase Change Material (PCM) like Erythritol which melts at 121C and won't vaporize until reaching 329C ? I'm thinking a certain mass of Erythritol be selected that would assure thorough melting for the amount of solar radiation expected to be captured. Placed in a tempered glass vessel at the focal point, once melted the vessel could be transferred to a heat exchanger of some sort.
Maybe a sand battery as an alternative?
Inspiring!
For the spot to not change it's shape, rotate the whole mirror assembly together with the receiver.
excelent video
Just have a think a torus antenna is as like as your parabolic mirror, the axis of rotation is perpendicular to the symmetry axis of the parabola and there is a need for a torus target. The distance between the axis of rotation and the rotating surface must be larger than the focus of the parabola. The torus target doesn't form a focal point but a group of focal lines, which lie on an arc in front of the reflector - wavefrontier toroidal - torus antenna - Тороидальная антенна
what about making a water distiller for producing pure water from salty water (sea)
Very good!
What type of oil do you use for this? I'd like to build something small-scale like this for a school project.
This looks like a good design, easy to repair. I would like to see how the heat is stored. I think a variable speed pump could keep the temperature leaving the collector at about 200 Fahrenheit.
Look at his other videos. He has a plastic dam under cover with water for heat storage.
200F isn't his goal. He's looking for (I think) over 300C. If he is eventually going to try and generate electricity, he'll need the highest temperatures and the best storage possible to generate steam. Of course, that's assuming he limits himself to steam as the working fluid. There are some plants that are using CO2 in a closed loop system.
Now the important thing in my mind is the conversion to electricity if possible. Do you have a video detailing a economic way to do this? I would add I have seen a solar tracker which used a windshield wiper motor from a volkwagen to shift the entire assemble and focus on the sun. perhaps if it was mounted on a turntable as well?
Hi
I take it your issue with the different times of day is that the collector is not following the focal point at the particular angle. A slightly more complex arm may be worthwhile. Would look at a series of pivots with balancing weights to lower any operating cost.(ie expensive motors)
He's covered that issue extensively in previous videos.
Just a wild thought but I wonder if you get around those problems of collection with a simple servo-motored setup on the base of the whole unit like you would find on a telescope?
Ceramic black heat exchanger
Mirror curve has to be adjusted the top to bottom I believe??
Rather than wood arms, can you use wire? This would cast less Shadow.
What are you using to convert the heat to electricity?
Try copper mirrors. They reflect in the IR spectrum.
excellent
Hello Sergiy. Can I try to desalinate sea water using this design and generate electricity at the same time?
so, do you sell the solar power kits or teach people how to build them?
Shouldn't the reflector move with the sun in order to maximize the collimated light at the focal point and not the focal point itself?
10:36 There was a billion dollar concentrated solar plant that used molten salt as the working fluid. The salt was allowed to cool through some accident and the project was a total loss.
If you take a one hundred foot cylinder and a piston and compress the air inside to one third of its volume, a basic law of gasses says that the pressure will increase three times. Some temperature considerations will cause the pressure to increase more than that until the temperature returns to room temperature.
If the piston is one square inch in area and the piston weighs one kilogram, (need to unmix units) it will accelerate to a tremendous velocity within a short distabce. I forget how to do the calculus to get the exact number but averaging the force on the piston will give some concept of the velocity.
If the force starts out at 28 psi, it will decrease to 7 psi in abiut 33 feet. (28 not 42 subtracting the 14 on the other side of the piston. So if you average the force over that 33 feet suppose it is about 15 lbs. Converting to Newtons gives about 70 Newtons. Times the distance in meter of about ten meters is 700 Joules. This is equal to one half the mass times the velocity squared which gives v=sqrt(1400) which is about 37 meters per sond. If the piston weeghed one tenth of a kilogram the velocity would be about about 100 meters per second. If the mass is the mass of the air inside of a long one inch pipe, one might suspect that the air will reach a tremendous velocity.
Increasing the Kelvin temperature by three times has about the same effect as increasing the pressure by three times. Increasing the temperature from about 20°C to 700°C is about the same as increasing the T in the PV=nRT formula by three times. Since the volume is not confined, the pressure does not increase three times but the volume rapidly increases which increases the velocity of the spinning turbocharger which inreases the pressure and the velocity of the air coming out of the compressor.
But people tend to think of steam or jet fuel or natural gas when they think of gas turbines.
A small car turbicharger might be about the rights size for a home rooftop system. Many people might not want to deal with oil at 343°C and molten salt in a home rooftop system If the sys tem was flattened out and put in boxes with much smaller mirrors and pipes, it might make a good rooftop aystem. If it was enclosed in metal boxes with glass covers, the 700°C would not be as much of a problem and possibly quite safe. And if it is enckosed, birds would not be burned alive like they are in those big commercial projects.
What if the receiver is not flat but concave or of the multi section concave so as to focus the light in a more central areA, even with tubing
Very nice construction!
I was curious, if you could use this concentration method, and mount small solar panel in focal point, and cooled on back with water. This way you could make directly electricity with cheap (smaller panel, less cost, more light bigger efficiency) and in the same time cool it down with water making hot water for home heating. PRobably this design makes too much sun flux for such use, but it could be still interesting
PV solar panels work better with more "brightness", but also lose efficiency with heat. ~400 degrees would probably just melt them!
(Also no PV panel will be anywhere near 50c/Kw)
Somebody did develop a system of two moving, flat mirrors to reflect sun onto a static panel. That worked pretty well.
@@worldcomicsreview354 yeah tech ingredients video :)
I was not thinking about such big concentration XD But rob murray smith wastalking in one video about research in direction of use small panels with big concentrators
i just randomly had this idea today and searched to see if someones tried it
Is a solar collector which beams onto something to heat hotter than using a lens and shine onto something to heat? I would think the lens is more convenient, it’s smaller and easier to angle…
Will be interesting to follow up on this design. I am planning to use platinum coated HDD disks in similar design as I have aquired 100s of them at zero cost. Three problems I need to overcome: (1) they are round so there will be unused holes and spaces between them, (2) they are not flexible for curving and (3) the whole mirror needs to be made flat on the ground to survive frequent storms in my area :)
You can make it concave i and bury it in a concave hole in the ground, with collector traveling above it, similar to design shown in the video, just inside a hole in the ground.
Rain can be managed by digging a bit deeper hole and suspend a mirror above it so it doesn't get submerged by a heavy rain. Snow will be a lot harder to deal with.
Unused space is not an issue, it will just make the reflector bigger...
Just my 2 cents.
Cut small rectangles and put all together to preferred shape on another body like parabolic shape
If i where rich I would fund you further your work. I know its been done on a large scale but I think small units at each home is really awesome. If you can biol water can you not make steam for electricity also? I am curious.
Will it cause a fire if a leaf gets stuck at the right spot?
You seem so have a good understanding of solar thermal dynamics and physics. Why don’t you make your new reflective dish track the sun?
Lovely. I suspect Windmills would do very well in Ukraine also, although I don't know too much about wind there.
Also it's not off the shelf parts, but why not store energy in laser energy bouncing or circulating?
Can we use sand or rocks to store the thermal energy to be used later? At home, DIY
How does the 400° oil melt the salt?
How much power it can generate?
Why this was not mentioned neither in the video nor in the description?
Add a fresnel lens to focus the spot to a smaller area...
Keep working!
Очень интересно 😊
Sir, your videos are inspiring. I have been subbed for a very long time, and I have been impressed with your progress.
I have a question/suggestion:
Have you considered using an inexpensive Fresnel lens at the receiver, to take your already concentrated light, and further concentrate the pattern onto a smaller, hotter receiver? I mean, you must already use some glass/plastic to prevent convection cooling... why not make that one of those $1 plastic flat lenses? Would it melt?
It seems obvious from your video that it is the thermal collector that should be stationary, on a fixed steady platform. Down, not swinging around. Therefore, logically, it is the reflector that should be on a heliostat. Of course, you would also need perhaps two more reflectors. Thermal collector perhaps 3 meters away on a concrete block. Just saying.
Serhii, how much would you charge for constructing a heat farm worth of 300 kW heat power at winter night for keeping greenhouses warm in Subcarpathia?
Look into Chinese style greenhouses.
Cool
Thanks Sergiy! 😀
If we upscale this, we would end the world's energy problems.
If a factory was set up, steel versions of this could be mass produced. The salt tank could be stored under the mirror, and the whole thing put on a swivel to follow the sun (manual version cheap, or an optional motor and auto-tracker). Probably wouldn't be enough to power an entire home, but it would vastly reduce the burden on the grid and keep essentials going when the power goes off.
Also they could be put on the sides of roads, and the heat pumped under the roads to melt off snow and ice.
