It's cheaper than solar panel and gives electricity at night

- I described a new (3rd) class of solar power plants (in addition to solar panels and traditional CSP) and formulated the goals that we must achieve
Now we see solar energy which is reflected from this mirror, and focused in this way, and this receiver converts solar energy into water steam. It is a prototype of one of my solar heaters. My goals are described by this formula, which leads us to the cost of solar heat at the level of 0.5 cent / kWh, and it is approximately 10 times cheaper than the cost of heat from natural gas. In addition, this cheap thermal energy can be used to generate solar electricity which is cheaper than electricity from thermal and nuclear power plants. The 2nd half of this video will describe how we can turn this thermal energy into electricity 24 hours a day, both during the day and at night.
This is the prototype of my 2nd idea for the production of very cheap solar heat. I remind you that such experiments are described in detail in other videos of my TH-cam channel, and this 2nd idea aims at these goals which lead us to this cost of our solar heat, 0.5 cent / kWh.
Here we can see that the total construction cost of my mirror should be about 10 $ / sq. m. This is realistically achievable because my mirror consists of this mesh of steel rods worth $ 3, and this reflective film at a price of 25 cent / sq. m.
The mirror of my 1st idea is more expensive, and it is a mirror version of cheap stainless steel. The wholesale prices of these mirror sheets are less than 10 $ / sq. m. I remind you that I am aiming for this cost of my stainless mirror, about 15 $ / sq. m.
This is just the beginning of my experiments, which will be described in my future videos. I will also research and describe other types of mirrors for cheap solar heaters, and for example, now I am showing the idea of this American company. It is a balloon, made of this transparent film and this reflective film which focuses solar radiation. This is also a balloon, but it is very large and was proposed by this Austrian company. Its reflective film focuses solar radiation in this receiver.
This German idea is the 2nd example, and the basis of this mirror is cheap and long-lasting concrete. I plan to start experimenting with the cheapest option of similar concrete mirror in 2 months. This is the 3rd example of cheap mirrors, and I have been testing these mirrors at this my solar station for almost 8 years.
Of course, we know about traditional solar heaters for large solar power plants, and this is the 1st type of the traditional heaters. This is the 2nd traditional type of solar heaters, and this is number 3. This is type number 4, and now I am showing the fifth traditional solar heater type which is used by this new solar power plant in China.
Unfortunately, these 5 traditional types use very expensive mirrors and systems to turn them according to the movement of the sun across the sky. Their cost is about several hundred dollars per square meter, and it is 30 or 50 times more expensive than those cheap mirrors which I will research and describe in my future videos.
So, I propose the 2nd road to cheap solar electricity, which is parallel to the 1st road of these 5 traditional types of solar heaters. The 2nd road goes through experimental and economic testing of various types of extremely cheap mirrors and through maximum simplicity of our solar heaters. The simplicity gives us the following advantages: Low cost, Reliability, Small investment.
Which of the two roads is better, we can understand by similar formulas, and the winner will be the road that will offer cheaper thermal energy at the temperature we need. So, it is only competition, and I am not an enemy of these traditional ways, and I believe in their prospects and ability to win against solar panels.
In addition, we understand that I must find cheap options for such turns according to the movement of the sun. That is why I am looking for different options which are several dozen times cheaper than traditional ones, and i will describe them in my future videos.
Sergiy, as myself own a company making all kinds of solar trackers for 12 years, I am very familiar with concentrated solar. I first saw your channel 2 years ago and I am so amazed to see your experiment have improved so much. Also your wide collection of different concentration technology is exceptional. I hope to have a chance to meet with you after the terrible war. I check the map and found Myrhorod is only 270Km from Kyiv. Please be carful and stay safe. My heart is with you and your fellow-countryman.
The world stands with Ukraine 🇺🇦
I always liked the super heated oil system's..the problem is one leak and spontaneous combustion
@@aipman Concentrated Solar is usually too expensive for commercial application due to high cost compare to PV. Also the efficiency of concentrated solar modules can be much affected by uneven solar ray on the tracker. PV with agriculture is better than concentrated solar.

Dear Sergiy, I have been closely watching your research and I am inspired by your work. My prayers and thoughts are with you, your country, your loved ones and your people during this nightmare. I can't even begin to imagine what you are going through. Stay strong, hopeful and proud, sir. All the best from Greece!

massive red flag right here
Nice presentation..I'm a senior citizen now.
In the 1980's I was with a company here in the USA that was in the early stages of these exact systems that you are showing on your channel..incredible.
Very satisfying to see the
"End result" of all our research and development I was involved in almost 40 years ago. I will enjoy your channel that I have subscribed to..Thankyou for your efforts...
This has been done on a large commercial scale where after just 1 year the project FAILED and all of the investors pulled out. It now sits as a huige pile of trash in the middle of the desert polluting the landscape. These climate morons do more damage than good honestly. The lithium batteries and the short lived solar cells pollute the planet more than household trash and the Lithium alone is 100X's more toxic. Great work Climate Detectives the only thing you proved is how much you are willing to sacrifice in order to push forward with your delusional agenda.
Never stop! You are amazing! An inspiration to all DIY solar enthusiasts.
Wish I were younger.... brought back memories of my 5th grade science project from 59 years ago .....cooking hot dogs on a 4 foot diameter parabolic solar reflector built from cardboard, Elmer's glue & covered with tin foil.......lol.....worked pretty good on a sunny day!!
30 yrs ago the large parabolic dish antennas could have been used for focusing solar onto a collector. Putting hundreds of mirror pieces in place would be tedious but worth the effort in the long run 👍
th-cam.com/video/lbb4xwYj19g/w-d-xo.html
Fantastic! I work on my dad's ranch. We need a way to heat water as to keep the water trough ice free and easily drinkable. Ranchers and row crop farmers need this.
Concentrated solar would be over kill here :-)
Just get a solar heating panel - or experiment with painting an old radiator black.
You'll need to have some kind of temperature regulator though unless your livestock likes a nice cuppa ;-)
There will be a lot of difference between a sunny and a cloudy day.
This is great, thank you for sharing. The part I like most is that it would allow taking advantage of existing infrastructure: a fossil fuel based power plant can be converted to use steam generated this way, while keeping in place the steam tanks, turbines, etc.
th-cam.com/video/lbb4xwYj19g/w-d-xo.html
The main advantage of the parabolic trough is that the longer it is, the more efficient it becomes in the early and late part of the day, while maintaining mechanical simplicity not having to rotate two axes for it to work, just one.

This is fascinating and wonderful progress, finally I see it as our world is becoming free once again! More than 9,000 patents were suppressed here, but the people are now aware of it, and this will cause change to happen. Thank you for your patient and excellent work 🌏
Respect my friend there is so many of us now trying to get all this out to the masses !
get what out to the masses? Solar power, liquid salt, what we talking about here?
If you are ever planning to do something with the generated steam (like running a turbine with it) you first need to de-mist it (getting the tiny liquid water droplets our). You can do this by routing the generated steam through the solar collector/ heater a second time to superheat it or just make a thick filter from steel wool (the stuff you use to clean your kitchen is fine) and reroute the collected water to the beginning of the heater for a second run or use it to pre-heat the input water.
Where could one read more about what you described? Would a thermodynamics textbook cover such?
@@billsmith7673 I myself am active in the naval sector so I really wouldn't known a general book about it. All I know is that it is really important that water doesn't get into a turbine. This is primarily due to corrosion reasons, but also to reduce stress on the blades. The water has a significant lower temperature than the surrounding steam so when you run it, microcracks in the metal of the blades can form. I would get a book on steam turbines too look further into it.
@@indigenous.rabbit2877 Thanks. Interesting. Will check into a book on steam turbines.
What I like about the idea of focusing the sun's rays and heating something as a source of energy instead of using solar panels, is that it is not dependent on particular elements that come from remote parts of the earth. The elements needed for solar panels may come from countries that hold the elements hostage for political purposes. Also the elements need to be mined. As shown in these videos, mirrors can be made of a variety of inexpensive materials and the heat can be stored by a variety of common and inexpensive materials. Flexibility!!
I suspect pea-size silicate gravel has lower gas-flow impedance than sand, but similar Q transfer rate. Riverbed gravel with rounded surface should be preferred to crushed or coal-slag material because the smooth particles offer easier airflow. Need studies on gas-flow and Q transfer for various size particles.
I like ideas that cost very little or nothing and produce large amounts of usable energy.
An idea of mine is to use reflective sunlight stored in one of many ways and then using a heat pump to transfer the already high temperature to a pressurized tank to drive a turbine.
I've already been able to combine several technologies that cost me almost nothing to heat a home in the Winter and to make electricity to power several appliances. I started with a woodburning stove that was given to me, then I trapped the exhaust gates, cooled and condensed the wood gas in an old propane tank using a 2nd hand air pump for running pneumatic tools and using the wood gas and burning wood to make steam that drove a simple turbine electrical generator.
So much can be done to take old junk to produce electricity of heat for our homes in the Winter instead of paying utility companies.
Please make more videos and share your ideas.
Interesting! I think we have to create a new life style with that said, less energy wasted, more wisdom about what is useful, necessary, and how dogmas makes us wrong about a safe life.
Sir, please you also make videos of your innovative efforts...
I've an idea if we focus from mirror to solar panel then would it generate more electricity??
@@AkhileshYadav-ly2iw I've wondered about the same thing. Let us know if you try.
@@AkhileshYadav-ly2iw When I was a teenager we tried this with a home made reflector and the solder melted off the solar cell.
Dear Sergiy
I just found your video channel. You are a very rare hero for humanity. Thank you for your unselfish willingness to share with your fellow man.
My heart hurts for the pain inflicted on the People of Ukraine and look forward to peace for you and your loved ones soon.
You keep me motivated, I’m currently building a trough type system with a sand storage. I haven’t decided on which type of fluid I will be circulating through the system yet, thinking of temperatures near 400F. I’ve been polishing aluminum flashing materials up to 10,000 grit and it’s quite the mirror finish. Sorry about your country’s state of affairs but you are a great example of what a free country’s people are allowed to think and do!.
Would be nice if you can share your work in the future. Good staf!! :)
I have seen sand mixed with platinum and palladium flakes, then HHO gas to create heat. A German scientist demonstrated this on TH-cam.
Very nice and inspiring work please share your work. 🙏
Amazing we are so blessed to have all this talent in the world around us it’s crazy the resources we would have if the average person was allowed to share their work and not be mobbed down by giant corporations that stand to lose profits if these sorts of things come to market I think it’s time to have a platform with people can upload their ideas and other people can if they’re looking for information other people could add to it or they could find monetary assistance but in a Blockchain form so that it could not be tampered with and once the information is out there it’s out there’s so many patents have been stopped because of their efficiency unfortunately they get blocked at the patent office we need to bypass that people have a right to know that there are all these others out there with brilliant beautiful minds and great ideas and that’s what we need in the world today is great ideas thank you so much for sharing amazing God speed!

Sergiy, you get better and better in sharing neat discoveries, and closer and closer to your desired dream of low-cost, low-tech solar heat and electricity. Fascinating research. Thanks from all of us around the world. I am in North Carolina, USA.
John Gregory - Very well said, and I wholeheartedly agree, from Edmonton Alberta Canada.
Friend of mine in NC has a solar home. Poured slab is exposed to sun through windows during winter and shaded during summer. It's 13ft thick so acts as heat storage in winter. Smart building.
Agree from South West Bulgaria👍
Yup,he is doing an excellent job...

I've an idea if we focus from mirror to solar panel then would it generate more electricity??
Humanity needs more people like you. Thank you for all you do.
I am just a simple non-expert, but this seems to be a complicated conversion process best for large scale plants and less efficient (cost effective) for small plants, and it seems potentially dangerous. Solar panels and batteries seem to me intuitively, to be better for smaller applications that allow a more distributed grid. Its great that these sustainable energy technologies continue to be improved. Thank you for sharing your work.
That was great. With gas prices going through the roof in some European contries, even small systems can be worth while now. I'm lucky I live in a south facing flat and the sun heats it up quite a lot even in British winter.
It's great to see a method of harvesting the natural energy that is all around us - without the burning if any fossil fuels. Great work my friend! 🤓🏴🌅👍
I saw another way where no sun tracking is needed, just split the mirror into several parts, for example 12 or 24 smaller mirrors set up to focus the sun on the collector at different angles at different times of the day, and making them adjustable to compensate for the seasonal changes.
You could heat a black box full of air and run a fan to pump it into the house. I hope you stay safe during this ridiculous problem with Russia. We are all with you! (Wisconsin, USA)
A great mention for asking, "is that the best I can do to harness the sun's power?".
Now that's what I call harnessing the sun's energy!
If we include some IT, who knows where this could lead for the average individual.
Yessss please don't be private with a patent! We all need this ASAP.
"Cyber Pandemic" and all that coming 2022.
Good on you thanks I've had small scale solar system for 2o yrs now and it's surplied my energy needs about 90percent the trick is to reduce our needs smartly rather than just keep unnecessary wasted energy keep it up your system is a winner. I haven't seen a power bill for 2o yrs be t people who have never even tried are still saying it doesn't work good for you

Remarkable work !

where were your hearts while Ukrainians were killing Ukrainian women and children for the past 7 yrs??
The future depends on people with the same spirit as you Sergiy.
Keep spreading the word!
I would love the idea of the Ukraine being self sufficient with clean solar energy.
Know that we are very concerned about the current situation in your country.
Energy can be stored thermally in insulated containment. This could then be recovered back into electricity by heating gases through a reverse heat pump process driving a turbine. Mirrors are very cheap and easy to maintain.

Interesting video. Storage of energy is the toughest nut when it comes to solar. Look forward to more from you.
Not really, it's just stupidly expensive. Now with the competition of electric cars, hopefully we will se a big leap in battery technology, I know different companies are working on solid state batteries promising in the future cheaper, safer, durable and more energy storage.
The cheapest storage of solar energy is using thermal insulated container with hot water. No need of DC/AC converters, only electric heaters for PV panels /or hot water from water panels/. All heaters for 230V AC can as well work on 230V DC and less. And little pump on the top of container pushing the hot water out to your central heating system. This is good for winter in say European climate. So you increase the temp. of water in container during the sunny days and then use it in nights or cloudy days. You need some 500 liters container at least or two of them for your household. Also using mirrors as Sergiy does is a great idea, allowing to increase the power from panels 3, 4x in cloudy days.
@@marianskodowski8337
You're talking about heat storage and not energy storage.
@@mackjeez Heat is a form of energy. The most important goal is reducing emissions ASAP. If we could implement affordable solar heating that would cut down energy consumption and hence emissions significantly.
@@philipm3173
The point is about solar energy storage in general. Energy storage in a DIY environment was never an issue, get yourself several batteries and voila you solved your needs, what he's talking about is solar energy as a viable renewable energy solution (mass) and one of the challenges of solar energy is storage.
Happy to know you Sergly, recomended to me by a freind of mine. Like you, I also am a pioneer of such technologies, which started with thermal storage, from domestic thermal stores I first developed in UK in 1991, to next generation produced in Cyprus and 3rd generation made in China, before returning to my 4th Thermal Store now made in the UK, as I needed quality and long life, Then in 2014 I developed with my American partner a flat pack commercial thermal store, as shipping costs then were costing more than making the stores. in 2015, I shared everything with a Sth African heat pump importer/engineer, who were seeking a HW tank that could be sized to there needs. By 2021, over 600 installations were completed with stores produced up to 22,000 litres all flat pack
My last innovation after 2 heat pipe developments is a new light weight solar thermal panel that converts PV to PVT
Take care
Air/stones idea is the best idea. Years ago lot of years ago, as I wanted to be Architect, I designed a house with a south inclinated green house, and beside a double black wall. Hight positionned wholes from the green house let heated air going down the in between two walls in the in between space heating the accumulator mass, and return in the green house by low wholes. By night, all this is closed but wholes are opened high and low, from the in between walls accumulator to the inside of the house. In the same time, provide the day long oxygen, and in the green house by night, the carbon cycle go normally, low wholes opening to the low ground, the external black wall inside the green house still heating it by night. Actual solar houses models, makes ne laugh because they put the corridor to rooms in the green house, the CO2 nigh cycle is not respected with growing leaves along the corridor... this is stupid. So, I'm interesting about how making electricity with all that heating, by night also, but with a small installation, for house purpose. This link to a question to you, how many electricity do we realy need by night?..Night is the time we go sleeping, so if we have accumulated heating energy, we need only few electricity, for lights, fridge, and so what, no big need by night . An other question is if climate go to cloudy days, or Sun activity going down, the problem would be different. So accumulate heating, for example with hot air and stones at home, for weeks or for cold season at home scale, is interesting me a lot. Some ancient people were designing their house in stones, or under caves, or partly under ground, trying to stabilize temperatures inside. This is also a air/stone system, but this can be modernized. In a cold climate, the need of a warm green house is needed, so my old design is a thing I have in mind for myself, because what I know of future, is mostly cold and cloudy. So I'm thinking about to combine green house to my home, here in south Bulgaria, using free Sun energy. Note the double accumulator wall is a very heavy thing, and the material used must be stone and concrete, and part of the build in house to be a solid thing the inside house part of the double wall must be isolated.
Hi, do You still have this project and wanna share it with us?
The kind of wall you describe is a Trombe. Very cheep and relatively efficient. I was considering at one house that was on 1.5m stumps, that I'd pile up tiles and encase in fibreglass bats or pottery kiln insulation, with a fan to draw cool night air through and through simple flap valves, redirect during the day for cool air inside. The same could be done for heating, if the pile was heated directly by a reflector, or through a air pipe.
just an added note: You can switch off all electricity at night for say 8 hours easily, the fridge won't mind, a few battery and sensor operated LED's will give you all the light you need at night.
I was working in Richmond Hill this week. On my way out I decided I take a drive to Tesla Canada to see if I could meet someone for a tour of the Canadian facilities. I come up with innovative business ideas on a daily basis so I feel like I can help with the transition to sustainable transportation and energy. We all know there is corruption in finance markets and politically with the use of oil and gas. I would like to continue to contribute what I can do to help this world be a better place and allow humanity to spread its wings. The time is now to stop corruption and all of our actions should be built with love consciousness in mind. All matter is built from love consciousness energy and all that matters is love consciousness energy. Let's shoot for the Moon and Mars, then we will end up amongst the Stars!
In the cost equation @0:36 , your units don't make sense. You can't add "USD" to "USD per meter". Proper addition requires the units to match. You probably meant 15 USD/square meter + 20 USD/square meter, multiplied by the size of the system (in square neters) so the square meter units can cancel out. Note square meters (m^2) should not be designated as "m" or "meters", the units should be "square meters" (or "m^2").
But then you also divide USD by time (in years). The units would now be "USD per year" (or "USD/year"). Again, the units have to follow algebraic rules.
Your right side equation result shows the cost per unit of energy (kWh). Since area (in square meters) was neglected, the cost per unit area was left out.
But if you intended to calculate the cost over the life of a system (as a function of installed area), that becomes a different equation, in units of USD/year per square meter.
Checking if the units are correct is a quick way to validate some of your equation. If the units turn out to be wrong, then you're equation is probably also wrong.
I have had this basic idea myself. I have many ideas, but no skills, tools, know how, or funds to implement them. It is great to see them thought of and implemented by others!
what idea do you mean? I'm curious 😃
I have many ideas and the skills and at least basic tools to implement them. Just no garage. Look at all the rich people. It's always all about the garage.
Thanks for sharing the developments and possibilities. Agricultural farming underneath the collectors is also greatly useful approach to solar energy collecting farms! That I dream of!
Your focus on starting with the cheapest materials is probably what will make it successful.
I’m very impressed, this has sparked my curiosity

Most interesting; thank you. I once saw a project where recycled glass containers where broken into small pieces using a sound-vibration technique. Then the glass pieces were used to fill pits in greenhouses, with hot air introduced during the day through perforated tubes. Then the glass radiated heat after sundown, which greatly enhanced plant growth.
tell me more please. do you think you could give me a link to that?
@@justthinkalittle8913 I wish I had a link. If I remember correctly I saw it on a PBS show several years back.
Wonderful. Hire security from oil companies, politicians & government bureaucrats. This is great.
Any distance that the proposed thermal energy must travel will be lossy. Therefore a large thermal mass with several reflectors local to each other makes sense to me. Bonus, in a closed loop system the thermal transfer liquid could cycle by thermal energy alone. Coupled to a very small turbine charging liquid based full cycle batteries seems feasible.
Multiple turbines will be expensive though.
... I don't suppose you can put the generator on rails and cycle it between several stores? ;-)

Thank you for embarking this journey towards cheap sustainable energy and sharing the results with us. Can't wait to see the final outcome 😛
Greeting from Ontario Canada Yes thank you for sharing your knowledge it’s much appreciated
Discovered your channel right now, understood you're located in Ukraine: my best wishes and solidarity, from the very tip of northern Italy.
Nice concept.
The efficiency can relatively easy be improved by releasing the steam in a heat exchange cover around your water source so warmth and water can be partially recovered… warmer water will result in a higher frequency of steam bursts. Etc etc…
🤤 that's for writing that!! Delicious ideas here
As far as I understand, the only advantage of using thermal oil vs air and molten salt vs. sand or rocks is compactness. I tend to agree with you that this is too slim an advantage compared to much greater complexity and cost.
Nice! I like the idea of using mine tailing as heat ballast! That's easy to come by and eventually may result in New materials & uses!
Good video. Seems like some sheet metal or plastic sheet would cost a lot less than regular solar panels.
Seems like a very inexpensive residential system could be made like one of those in the video with trough mirrors heating compressed air in pipes to drive a car turbocharger and storing the exhaust heat in a pile of gravel. Most residential energy is for heating and cooling. It makes more sense to bave the system where the heat can be used instead of at some disrant solar farm. It could be made like solar panels with narrower trough mirrors and smaller pipes so that each panel maybe one square meter is only about a foot deep and covered in glass. Aligned east west and angled for the roof with one central support it would only need to move the mirrors inside the box without moving the panell and the air intake and exhaust. The same turbocharger could be used to extract electricity at a later time like a battery. In a cold climate, generating electricity and using the exhaust heat for heating would be multiple times more efficient than regular solar panels. One little motor in each panel connected to a lever to tilt all the mirrors and connected to one main control system would not add great expense to the system.
Gravel cooled down by hundreds of degrees below zero could store cold for days or weeks in a similar fashion. Even the cold could be used to drive the same turbocharger by expanding cold air with room temperature air. A ton of gravel heated by 500°C stores 100 kwh of energy. A ton of gravel costs $50 compared to $100,000 for a 100 kwh lithium battery.
The sheet metal and pipes might cost $1000. A car turbocharger can be bought for less than $1000. There are turbochargers now that have a builtin motor/generator to avoid spool up delay and recover energy.
If it had an electrolysis system to make hydrogen it might save hundreds of thousands of dollars on electricity, heat and fuel over a 30 year lifetime for the system.
The thermal panels and thermal battery might cost 20 times less than a similar capacity conventional solar panel system and battery.
There are high temperature,high efficiency solar cells for concentrated solar that would add another 30 or 40% efficiency to the system. A thin row of the solar cells along the length of each pipe might cost a lot less than a roof of conventional solar panels.
If the turbocharger generates electricity at 30% efficiency and the concentrated solar cells get another 30% that is like three times as efficient as regular solar panels. The subtracting would add another 20 or 30%.
Some say concentrated solar is only for really sunny places. But regular solar panels lose most of their power when a cloud goes over the sun so how much difference is there.
How many kilowatt hours could it generate on a sunny day? If the pipes collect 70% of the heat and the turbocharger generator is 30% efficient that is 21% comparable to regular solar panels. 50 square meters of panels is about 10,000 watts. Times ten hours is 100 kwh. 200 kwh with the concentrated solar cells attached. If the average house uses 30 kwh, the extra electricity sold to the grid is maybe $30. Selling electricity generated from the heat stored in the gravel is another $30. A hundred panels might sell $100 worth of electricity a day. A one day supply of electricity from lead acid deep cycle batteries would cost about $5000. Ten tons of gravel to store two weeks worth of heat and electricity might cost about $500. A 10,000 watt backup generator costs $1000. An electrolysis system might cost a few thousand dollars. There are 8 kilograms of oxygen generated for each kilogram of hydrogen. If one kg of hydrogen sells for $14 and one kg of Oxygen sells for $2 that is $30. A hundred panel system that generates 200kwh a day of electricity would make about 3 kg of hydrogen at 50%efficiency which is $90 on a sunny day including the oxygen. Times 50% sunny days is about $17,000 a year. If you had room for another system, that is about $1,000,000 over the 30 year lifetime of the system.
If the system costs $10,000 and generates 100 kwh a day figuring 50% cloudy days over 30 years is like getting paid $1.00/kwh.
Nice! Your system could pass through a row of 20w each TEG modules, in a heat exchanger and the snow is a perfect cold side! That small mirror could easily make 500wh of energy. Cheers
Unfortunately TEGs are like 6-7% efficient at best
@@Kinetic_CGI a peltier is very low output but if a TEG is 20w?A 5×5cm space gives you 20w each. On a system like that you could attach loads of them and still have the steam!
Any solar solution needs to be contained to avoid other safety and environmental issues. Harm to wild life, further reduction of pollenating insects, etc... On the other hand, how cheaply this actually can be done for is quite promising... Maximum density in minimal space to make it transportable and installable would be the holy grail. I think that social media would be a great place for tomorrow's energy pioneers to openly present their ideas to the world. We need all the help we can get.
Great work Sergiy. I often wonder where all the big square focusing lenses from overhead projectors ended up. Must be thousands of them. Stay safe.
This is great work. Prayers for you and Ukraine.
You're doing great work. Just a thought here, but have you considered using fresnel lenses instead of mirrors? I don't know how cost and efficiency numbers would work out, but the lenses are fairly cheap. In single unit quantities full page plastic fresnel lenses are about $5 U.S. Credit card size ones are about $.10 each. Quantity purchases are likely far cheaper.
You can get these for free - if you salvage old projection TVs. :) Be warned - outdoors, have a slip cover on them. As a kid I leaned one up against the side of the house. I melted the siding! :D

Tamera village in Portugal has used a fresnel extrusion sheet. Overhead arrays in their solar test field there are adjustable. The hot oil is collected for continual or delayed steam production, a large one meter diameter sterling engine produces AC for power tools, pumping, etc.
Who makes this one meter wide fresnel extrusion material?
Inspiring and motivating work indeed. May you, your family, and your country be blessed and be protected
This is very interesting and kind of makes one understand there are real, feasible alternatives and real great, feasible people improving them. Go Sergiy!
what exactly did you learn from this video if I may ask?🤔
@@Broocklebut there are people out there working on things like parabolic mirrors can be used to focus sun's energy in a way that creates alt solar heating solutions?
What exactly is your obnoxious rhetorical designed to achieve?
@@ThanksAgain i c how it is 😅
@@Broockle could you tell me how exactly is it? Hahaha
@@ThanksAgain
well since you ask I'll tell you.
You have watched this video of a guy doing something vaguely environmentally friendly with numbers so he must be doing science.
You cheer him on but in reality you have no idea what his machine does.
His machine produces steam somehow but he doesn't elaborate how it works at all.
Really this video loox like a sham for attention and everyone in this comment section who left him positive feedback has no idea what it does either.
This is what I call a facebook comment section where everyone just lives in their own little echo chambers oblivious to any critical thinking.
No offense to you personally. Just my observation here.
Thank you Sergiy Yurko for all your creative experiments and practical solutions in the area of inexpensive clean energy generation. You are an inspiration! Thank you so much for your effort!
what exactly has he made that impressed you so? 🤔
Hi where can I get a turbine for this system? How do i calculate the specifications for the turbine? This is very interesting thank you for sharing
You need to know how much pressure the steam generates because a turbine needs a pressure difference to funtion.
Linear Fresnel is by far the best idea. Easier to construct and maintain and also to clean flat mirrors. Cost cutting in the plumbing too as the pipes are stationary and do not move like in solar troughs.
Not only did the molten salt solar plant in Nevada never match its expected production output, but it turned out to be too expensive to operate.
idd
You mean the first generation of an experimental design wasn't tip top, eh? Imagine that, a new tech that needs to keep improving! Shocking!
Get outta here.
@@MaryAnnNytowl Improving with whose money? Yours? Are you investing in these go nowhere ideas? Have fun losing your money.

Very interesting. Thank you for sharing your insights.
Chiayo and keep what you are doing up. Cheaper does not have to be worse. With your case it is even better. God bless!
Dude, love your vids, I appreciate the work you have done and also the enthusiasm you have for this, keep it going 👌🙌🙌
Just got your video dropped in my viewlist. Hope you and your loved ones are fine and well. Stay strong and healthy! Good luck for this unbelievable nightmare you are in (or hopefully already out and safe)
I've always thought that thermal energy storage was highly cheaper than chemical. However, the issue is the loss in a full storage/retrieval cycle. What you work on, where the loss is acceptable because it affects energy acquired for free, sounds like a great principles. Also, working at high temperatures. Do you know of any attempts at low temperature, using plain water as heat storage?
People use thermal arrays on house roofs to heat domestic hot water routinely, there's nothing particularly exciting there. To be able to get electricity, however, you need steam to drive a turbine. The 100C boiling point of water implies that it is advantageous to use conduction and storage media that is less volatile at much higher temperatures than water. Hence the suggestions the author mentions towards the end of the video to upcycle refuse/tailings from high-heat manufacturing processes.
@@freezerlunik I meant for full cycle storage, i.e., using electricity to pump heap from cold to hot water, and using the temp difference, however small, to get current back. I believe the closest to this are efforts at power generation from the difference between surface and deep layers of lakes or artificial basins, but that the efficiency is terrible, and therefore turning such a system into a full energy storage would have huge losses. And no, technically you don't need a H2O steam turbine to get electricity, you need a thermal (Carnot) engine of any kind, which you could create even without phase changes by cycling adiabatic and isothermal heating and cooling of any gaz. It's just the power/cost ratio of the generator that has so far argued for the use of water steam.
Sergiy, please stay safe. Your success in cheap solar energy can save the world!
Stirling engines can make electricity from temperature difference. I'm not well versed in it, but it might be intereting to look at them.
They are very efficient but require very precise manufacturing, thus expensive.
@@phrozenwun Expensive, as of now. There was a time when this was true to solar panels as well.
@@Sekir80 I've an idea if we focus from mirror to solar panel then would it generate more electricity??
@@Sekir80 you can get to know about the problems of stirling engine in this video
th-cam.com/video/mrV_c__mbxI/w-d-xo.html
@@AkhileshYadav-ly2iw If the mirror is so large that the focused beam in the focus is the size of the entire photovoltaic panel, then higher electricity production may occur. Since the photovoltaic panels are already large and the whole area uses solar radiation, the mirrors do not make sense, unless they are many times larger. Photovoltaics is nice in that it attaches to the roof and you no longer have to worry about the panels or invent ugly mirror sculptures that the wind would take away. Mirrors are not for amateurs, but for large companies with large plots of land or deserts.
This is BRILLIANT and BRAND NEW. ... You should be getting financing, a factory and building a $BILLION company.
Sergiy, I love your work on solar heaters. I am hoping to experiment with your designs this summer. My understanding is that you are using sphiricle mirrors, rather than parabolic. This makes a lot of sense, my brother explored spherical reflectors a few decades ago as a satellite antenna.
I am confused by one thing in your design, however. The arm that supports the receiver is mounted to the base of your mirror. Wouldn't it work better if it were mounted halfway up the side? Then it would ark around the focal point of your mirror.
Keep us posted as your dream takes shape, looking forward to more brilliant ideas
how strong is the mark aisi 430 ba film? would it withstand 50km / h wind from behind? we have such wind from the north occasionally
I'd suggest good strong backing sheet then along with the usual frame and anchor/foundation preparations needed anyway. Debri may be a problem.
@@seeker1015 i was wondering what sergeiy thinks about it as he handled the material
Thank you. I'm fascinated with the air transfer. My grandfather had black roof water pipes to help the hot water heater, I was always fascinated about ways to make it more efficient. I don't have to worry about pipes freezing here in Florida. Back to air... there is a patented pipe setup that separates hot air from colder air. And I think with a proper venturi injector you could keep the air moving down a long path (in a parabolic trough) without pumps/fans of any kind (much like a tesla valve). Would seem easy to move a simple generator, and move waste heat into a Granite basalt TEG where the cold side is maintained by on demand water flow. Here we are concerned with A/C systems mostly and not heating anything but water. Power from the solid state TEGs could first be applied to a proper refrigerator system and the generator could be expanded to run like a turbocharger ...where the hot side generates and the cold side just circulates the home air. Everything can be done with common stuff except the TEGs and refrigerant system. I have a refrigerator from the 1940s that cools by heating, I believe it uses an ammonia ... so it's probably outlawed. But I believe small scale system which you demonstrate could actually 'off-grid' a home. Where a solar panel system can only reduce power consumption (from grid) and cost $10k, I think a better integrated system could cost the same and eliminate grid consumption altogether. of course, people like myself who have their own water pump wells benefit the most imho. The heated granite w/ TEGs continues to feed energy well into the night and the parabolic isn't really required to run A/C systems at that time either. I've only had to run heat for two half days this winter, not even a good excuse to run my fireplace. We prefer to just bundle up. People I know N of us, heat stones in daylight and bring them inside at night for warmth during winter ... not very efficient, but they didn't freeze either with zero budget for heating oil or space heaters. I don't believe large systems should be created for greater than a couple hundred homes, the cost of scale loses its advantage. Keeep making inspiring videos. I believe plastic fresnel lenses combined with the parabolic is the way to go. I have a fresnel, they made them to magnify television screens and as toys back in the day. it's very cheap and powerful. maybe add water pipe hammers to your demo system to regulate pressure a little better? Do you have a float valve in there for water volume control?
the best way imo to heat water at summer are solar water heaters
my whole country uses them and they are very efficient and we don't waste any electricity on heating which is cool af
True members of humanity appreciate your work.
We are VERY MUCH praying for your safety. We hope you do not see danger.
There is more than one way to skin a cat. Keep up the good work! You can run molten tin at over 2200 degrees to solid graphite block stone for storage.
the inside of your potato chip bags are aluminum and give off so much heat, I posted a tweet about it six months ago, wondering how to capture that heat and use it. This video says it all. Thank you and stay strong.
it still requires solar energy to work. this reminds me of one of those "free energy" machines
Perfect explanations. I hope you and your famíly are safe and well.We are praying for the war end! God bless!!
Thank you sergiy. You have a fan from the USA 🇺🇲.
I don't know about producing electricity, but that's a great idea for heating a house. Right now my solar panels cover most of my electricity needs. But heat in the winter is a huge problem that requires natural gas and a lot of electricity. I'd love to use solar to heat my house like this.
Thank you from Russia!
You're a good and smart man.
Hope you can stay safe and keep up the work in these troubled times.
This is a very practical way to use the heat from a mirror. Great idea.
Thanks for your insights. Fact based information is always appreciated.
This is really clever! Solar farms using this would be far more efficient in energy generation on a cost benefit analysis than solar panels. Only issue is how to store and transmit energy.
Would be nice if true, but if you look at the commercial plants that have tried this, they have not been able to operate at costs lower than solar panel farms in the same area... there is a reason panels are dominant.
Though it dowa get a little murkier when you add the cost of power storage into the calculations.
Wishing you safety man. You're doing incredible work.
Sergiy your solar thermal research is very genius I am so sorry about your homeland Ukraine crisis and only want peace very much Excelsior on your endeavor...

I've been working on a very similar small scale solar steam boiler to power my sailboat. I have many ideas that would greatly increase the efficiency and decrease the cost of these solar boiler systems.
What about the system in Port Augusta which uses the stored heat to grow vegetables. Is it cheaper to make electricity this way instead of buying solar panels??????
