How these mirror toys can generate cheap solar energy
HTML-код
- Опубликовано: 1 янв 2024
- Many of us wanted to turn a satellite TV dish into a concave mirror. Now we see how a mirror dish focuses the solar radiation, and it is obvious that this point will have a high temperature, which can set fire to wood, or blow something up, or melt metal, or for cooking. Usually a satellite dish is turned into a mirror through sticking small pieces of mirrors, or sticking reflective films, or some other way.
Our concave mirrors appear to be very cheap, and therefore it seems to us that they are capable of producing cheap thermal energy and electricity. That is why we ask the question, can we install thousands or millions of our cheap mirror dishes, which will give us a lot of cheap thermal energy and electricity so that such solar power plants are better than thermal and nuclear power plants and solar panels, and the answer to this question will surprise you.
Now I am showing the 1st option, which suggests that a mirror dish would focus solar radiation onto a similar Stirling engine. These are examples of the 1st option from various bloggers, when a Stirling engine converts the thermal energy into rotation of an electric generator.
The 2nd option suggests placing a small solar panel here, similar to how this mirror dish focuses solar radiation onto this photovoltaic panel which is water cooled.
The 3rd option is used by this Indian solar power plant, where the solar radiation from the mirror dishes is focused on these cast iron receivers and heats them to a temperature of about 400 ⁰C. The thermal energy turns water into steam which moves through these pipes to this turbine with an electric generator.
Unfortunately, those three options are not suitable for us because our goal is victory over thermal and nuclear power plants, and therefore the cost of our solar electricity should be about 5 cents / kWh. In addition, I remind you that we want our mirror dishes to be better than solar panels.
That is why we must pay attention to the fourth option, which is used by solar power plants of this type. We know that solar radiation heats these pipes, which are filled with thermal oil with a temperature of more than 300 ⁰C. This hot oil moves through these pipes to the center of the solar power plant, where a proportion of its thermal energy produces steam for the turbine, and the rest of the oil energy heats thousands of tons of the substance in these thermal storages to a temperature higher than 300 ⁰C. Then, in the evening or at night, this hot substance produces steam for the turbine, and this is one of the advantages over solar panels, which produce electricity only when it is sunny.
In addition, one of my old videos described how that hot substance can produce electricity for several non-sunny days in a row, if that substance is concrete, gravel, sand or other cheap materials. The next advantage over solar panels is the ability to generate electricity during a non-sunny winter as good as during a sunny summer, if the heat storage is a large mass of soil or cheap waste, as described in this old video.
In addition, my previous video described how similar solar power plants can provide a lot of cheap thermal energy for industrial processes for factories, and my future videos will describe the possibilities of supplying the cheap thermal energy for district heating and greenhouses.
The use of thermal oil is not experimental, but a well-proven technology, which has been in use for more than 20 years, and investors have already built more than 100 such power plants with a total cost of about 40,000,000,000 USD.
Unfortunately, these mirror systems generate expensive thermal energy, about 2 cents / kWh, and therefore their electricity is expensive. That is why thermal energy from our mirror dishes should be 4 times cheaper, about 0.5 cent / kWh.
So, our cheap dish should have a similar receiver, which will heat thermal oil to a temperature higher than 300 ⁰C. These are more decent options for receivers for heating liquids.
Now we see that a dish with a receiver should rotate from morning to evening according to the movement of the sun across the sky. This rotation is done by a device called a "Dual-axis tracker", and this device is widely used as a location for solar panels.
Of course, our solar power plant will consist of a large number of mirror dishes,
which heat hundreds of thousands of tons of cheap substance to approximately 300 ⁰C during solar hours. The thermal energy will generate steam for a turbine both day and night.

Okay Sergiy, I have really enjoyed your videos and I understand getting the cost down is very important and what you use to take advantage of the solar thermal energy is important.
Having said that, you always say 3 constants:
1) use an oil as your thermal capture medium
2) storage into a medium (sand, concrete, etc),
3) use the stored energy in the use of a turbine steam generator.
Therefore, wouldn't it be smart to create the parts 1, 2, & 3 even as a test models while you're working out the mirrors & tracking?
This ONLY works if 1, 2, & 3 are set up in some way that makes "residential" use possible. I, and I'm sure many others, would truly like to see this in testing (small generator & storage). Not unlike CAYREX, and Blade Attila, who have amazing channels, it would be truly inspirational and motivational if something more "complete" were attempted. Without it, this is all just theory and while the videos are enjoyable, many of us will just move on as the world demands us all to "solve the energy problem" that many of us are expecting. So we can't waste time.
Just a suggestion and again, I do appreciate all that you have done but you have made the same version of your video about 30 times now and its time to see something new.
Cheers.
sorry and happy to share this with you boss , but both or most all of the currently used systems have at least 2 flows that greatly reduce their production as well as drive up the cost of kw per hour. When you all get ready and real about producing cheap power 24 hrs a day all year around . Please have Mr. Elon Musk find me & have him bring his check book as I know 2 ways to do it based on re or should I say arraigning currently proven tech. to get maximum output from minimal cost and no further input. Oh and tell Mr. Must manyor most any location urban or rural also with minimum environmental impact. I'm not getting any younger so time is an important factor in regards to my longevity . I work 1rst smart so I need not work as hard. But I do not do this work cheap , But as Mr. Musk has positioned himself & various companies in a very good configuration as well as position, he has the foresight and desires to do many of the same things that I do, he is not afraid to do the things others dare not,and lastly he has many ways to strike a very mutually advantageous deal with me that very few if any others do. for instance a share of both Tesla & the Boarding Co. stocks & oppositions, my own fleet of various Tesla vehicles , select properties of my choosing , power storage units, as well as bounds and currencies. And maybe some other long term contingencies . Let's do this and quit killing the planet it creatures. while providing truly green sustainable energy production for all. my designs work in most all environments & spaces.
also to your very wise points mine needs no power use for tracking, no or at least very little oil for movement of oil, the storage is some what simulator in my desing but much more efficient and none existing in the other as there is constant power production And if it makes people feel more comfortable they could easily add Tesla batteries in their systems which could be sold back to grid & there by potentialy but not likely reduce those prices.
Agreed, I'd love to see a DIY'd automated system we could install in our own homes even if it's just for heating rather than electricity.
The issue is finding a stirling engine that can produce enough energy for home use
You could probably produce enough steam for a Tesla turbine generator, as well.

Try GOE from china they have 10kw and 30 kw engines
Дуже радий вашому поверненю.Сподіваюся ви будете й надалі робити цікавий контент.Успіхів
Money could be saved on the dual-axis tracking, using the old method of having a dedicated solar panel for a pair of motors for the vertical, and another for a pair of motors for the horizontal. I'm sure you've ehard of this but for example the horizontal motors, when one recieves more light it turns the rotating platform one way. This system naturally points the dish toward the sun at all times.
Thanks!
:)@@MaacAbra
Love it! Cant wait to see the results
Super! Thank you very much!
Stirling engines work on temperature difference between two cylinders. Heating the hot side is easy but we shouldn't ignore the cold side.
I'm picturing two sand batteries located side by side, one for heat and the other for cold, on valve switched circuits. On cloudless nights point the mirrors vertically to radiate heat from the cold circuit out into space.
The Stirling engine's two cylinders can be embedded directly into the sand batteries.
It might take a month or more for everything to start working, depending on the size of the batteries and mirror array, but once it starts it could continue working for extended periods of clouds.
Good work
You are the best!!!!! I love your videos, this is science.
Very nice! I like! High 5!
Good one, which oil do they use?
I like the cooking in winter at 0:27

Has anyone researched using the oil as a direct heat storage method instead of a thermal movement device? I'm wondering if it's not a bad idea to decentralize the generation on the south side, hills/turbine to the north, and a city in the middle. Not In My Back Yard crew will certainly cause a fuss, but less so when they have no gas bill. Expanding it further could funnel a network as large as the US itself! Great videos stay safe and can't wait for the no need to move one!
Sand is the very best thermal storage medium
There is a Finnish company who stores heat in sand batteries, a Danish company (Stiesdal) working to store heat in crushed basalt rock (or any other kind of rock), and several US companies investing in thermal storage as well. In my semi-educated opinion it's a leading candidate for grid-scale or off-grid long term energy storage.

just maybe the way to go would be to use heat energy directly (without conversion loss) and only use photovoltaics for electricity for what remains.
We can use sun heat energy to heat oil to high temperatures and in turn heat the water to 60 C. Then we use both. This would allow:
- radiators in the winter (60 C water)
- hot water boiler (60 C water)
- dishwasher and washing machine (using 60C water, heating elements removed)
- refrigeration (absorption fridge with flame removed and using heated oil instead)
- cooking (in a way diesel cook stove works, but using heated oil, also oven in the same way)
- possibly even some kind of AC with absorption cooling in summer
Finally we could use (or not) some thermal battery solution (soil, sand or pool of water) to store excess heat during summer for winter. There is a formula for how deep in the soil your tube needs to be to shift heat for say 6 months. Not sure how this would go, maybe to help preheat (water)? Or heat air? Since this is not cheap it would be nice if it's not needed. But if you want a winter garden... then I'd say it is a must. This "battery" also goes both ways, since seasons are shifted it's used to heat in winter and to cool in summer.
Lastly, we need a fairly small photovoltaics+battery (vanlife like) solution to:
- keep LED lights on
- about 10W per notebook/tablet/phone (perhaps better to forget big gaming rigs or laptops and big screen TV)
- other low power devices, security cameras, alarms, home automation
- occasional use of power tools, vacuum cleaner, kitchen gadgets
This would need occasional generator use (bad weather in winter) and frankly if offgrid is not a must, it's probably cheaper to pay some small amount for the grid since all big energy consumers are handled separately. Even only the first 3 from the list would be great.
Interesting analysis. What strategies would you suggest for a tropical location?
Good point and really interesting analysis!
But probably the generation of CO2 heat pumps would help to solve a half of this points - so you would only need the sole panels (plus wind turbine for the winter season). And also geothermal is great for winter heating but still too deep and expensive in lot of regions.
Keep on good thinking! That’s what makes the progress :)
Regarding the tracking stuff, needing logic and energy to track and move significant masses --- if static mirrors can be constructed cheaply, then mght a network of pipes with valves to route the oil through the current 'hot route' be a useful appproach?
Instead of physically moving mirrors and/or pipes, just have static mirrors and pipes - different ones for different angles and times of year -- and then route the oil through as desired... The inefficiency of 'small window of use' offset against 'efficiency of no physical movement'.
How many additional pipes do you estimate would be optimal?
I use mirrors myself, but for producing electric energy there are too many mechanical parts that need maintenance, you need a tracker, a steam engine, a generator and don't underestimate the noise it produces.
Is the cost and type of thermal oil already included here?
I have an idea, it may be crazy, but at least it could be evaluated. If a thermocouple is used to generate a current in a conductor and an inductor to capture the frequency and its subsequent conversion.
Use SAND underground for heat storage
Hydraulic tracker. No gears. Use wind dithering to help move.

I thought you closed the channel! Why didn't you link to the new channel? I missed so many videos!
Now I have to catch up.
Glad you're doing well!😅
Wouldn't your equation change when using bigger mirrors
Solar panel maybe are weaker, but they easily can be spreaded. It can be installed on roof, on balcony etc. try to put hot oil tank on your balcony.
How about a long cheap stationary solar reflector trough facing towards the equator so that the focal point (line) tracks east-west with the sun. Add a strip of solar cells closer to the trough than the focal point to spread the concentrated light over the width of the solar cells. The only movement is moving the solar cell strip up and down daily(weekly) to track the angle of the sun. With the right balance of solar cell width, the cells can be more efficient with the concentrated light and avoid the extreme heat of being at the focal point. A simple radiator fins cooling system could be on the back of the cells to increase efficiency.
the current designs of any large scale use some of their power produced to run solar tracing & there by reducing available production volume Which drives pricing. also with out this added tracking in current designs solar systems in general are at best producing 70 to76 percent of their announced ratings. same with most other current green power production designs as are in use. but both or most all of the currently used systems have at least 2 flows that greatly reduce their production as well as drive up the cost of kw per hour.

What about using a steam engine turbine?
Could something like sunflower oil work? It's autoignition is 678 and smoke point is 412.
Is a small Stirling engine + an electric generator really cheaper and more efficient than a solar panel of the same area as this parabolic mirror?
yes & no because both of the current desins of any large scale use some of their power produced to run solar tracing & there by reducing available production volume Which drives pricing also with out this added fracking in current designs solar systems in general are at best producing 70 to76 percent of their announced ratings. same with most other current green power production designs as are in use. with this said however, I am happy to share this with you, but both or most all of the currently used systems have at least 2 flows that greatly reduce their production as well as drive up the cost of kw per hour.

You could look into passive solar trackers, much cheaper
loss of efficiency in coverting heat to electricity, turbines?
cost of such turbines etc.?
Solar panels are so cheap now that this doesnt make sense for electrical collection. It's still nice for having a free heat source. Also for big operations there is one currently in Spain, it's not very efficient and needs a lot of maintenance.
hello brother,can you make a powerful fresnel lens or parabolik mirror?
Why don’t they use a thermocouple? As I understand it the thermocouple takes heat and converts it into electricity.
لماذا لاتفكر في صنع عدسة محدبة كبيرة لتجميع اشعة الشمس هل من الممكن ان تكون اقوئ من الليز
I think you should rethink all of that. Why the solar panels are still so popular? Because of simplicity probably. And if I had to build much more complicated system involving piping, special oil agent, big heat storage with best insulation, then deal with the possible leaks and maintenance of the turbine and pressure line than even if it could be two times more efficient than solar panels I would still choose the solar panels for their ease of use and convenience… that is what people would choose.
Don’t get me wrong - I think similar and I support you but want to say that we should search for both simplest and most effective solutions to reach a breakthrough and make a change.
I’m also a big fan of the use of satellite dishes and was thinking about them a lot but unfortunately the only sensible solutions now are heat-cooking or generating direct electricity by some specialized solar receiver of industrial grade (like the one watercooled you have shown) - so this second option is beyond reach yet.
Good luck…🌟
Спасибо Сергей, надеюсь с вами все в порядке.
Solar mirror on the cheap:
Garbage can lid, solar blanket, sight vacuum will make the blanket concaved on lid.
Can it be used as a direct heatsource?
Yes, he mentions district heating @4:09
❤
The problem is cheap small sterling machines, generators, what machine oil or mineral oil will you use and so on. You need to make it as small as possible and as cheap as possible, also plug and play style if not nobody will even bother....
Do you need a tracker ? The position of the sun is known so a simple programmed motor could work but the programming would be a pain probably .
No you don’t! You just need to move to the equator - then you just need tow write one simple program for all of the days 😊
Solar steam running on air vane motor please 🙏 i wanna see pls upload videos 😉
🎉
Biggest problem I see is they only work if you can track the sun.
DEAR Yurko - Y whish you a prosperous and happy 2024 - Like all global energy production - much cheaper and truly sustainable (for rankine or stirling electrical generation or for industrial steam, etc.) - it can be combined via multiple, continuous and even hybrid reheating of a lot of thermal fluid circulating energy (such as Therminol VP II or LANX 500), I suggest expanding research to add heliothermal solar energy (PTC still with a thermal range of up to 450º C) with fast and very cheap syngasifications of MSW plus biomass and tires old trees, lawns, tree pruning etc.. and which also reheat the same thermal fluids mentioned, but now at up to 850º C. Only with such hybrid sums, will we be able to have fully sustainable hospitals, airports, buildings, stadiums, industries etc. and with very low generating costs.
Any units that need solar tracking have already failed to reach their maximum potential due to the inherent need to use a portion or any part of the produced power to power those drive units & control circuitry. A Properly designed system can be built with no needed moving parts save an properly sized turbine. or at least much less than currently mass used systems. In example of this I offer this design as well known design large commercial solar unitplants located in both CA. & UT. USA as well as several others around the globe. The documented records of these units speak to my points. They are 1st designed wrong as they need tracking systems to reach even the low levels of production as they do. 2nd the materials they are made of can only handle a fraction of the massive heat production levels they are capable of producing .
My designs both fix these 2 issues as well as others.
Let me throw you a bone, you are placing these various systems on a large ball that is moving around your solar source right ? You are currently using energy to track that solar sources . Wrong!!!
Let it chase your systems, & for good lord sake stop aiming them up through ( the bird infested air ) at towers made of metal. ( they keep melting every time you try to tune the systems up for higher production. ) Please is there no one in these classes that know basic physics or engineering ? And if so they should be fired. These designs were perfected in antiquity ! Please as they used to say "Your killing me here smallz" For good lords sake someone please have Mr. Musk get with me Please I CAN FIX THIS ISSUE .
No. This can not replace a nuclear power station. There is no efficiency of scale here.
I've seen theories like this before where people want to replace solar panels. Solar panels are unique because their design has a resemblance to nature(Photosynthesis). Just like airplanes the efficiency that they fly in is a resemblance to nature, those are unique technologies we should keep. Instead of refining that technology we have already discovered we are trying to replace it and that will lead to failure, I've heard of hydrogen,molten salts, balloons that generates power as the future of energy production but guess what, solar panels are used even on space crafts and one of those has already crossed the Kuiper Belt and still going and that is more than 25 years of power.
