Try the mylar balloons as a thin reflective surface. Inflated, they can be used as a form for the cement. Add reinforcing fabric to the cement. Don't forget drainage holes.
I have designed a cheap system using 2L PET soda bottles which are about 110mm dia. By covering 1/2 in Al foil and then inserting into a parabolic mold and heating with paint stripper gun then applying air pressure , it forms a parabolic trough wit focus at centre line , and then insert a 19mm OD 3/4" black plastic pipe and align east west, in series strings. in this way it needs to be adjusted once per month aprox. and only about it's axis. This covers 110mm or more due to the distorted ellipse very cheaply and not affected my rain hail snow or wind.
Competing directly with solar PV is getting more and more difficult, current development suggests it will soon be difficult to compete with a combination of Solar PV, wind and batteries. I think it's great that someone that understands the problems explores the options, and explains to the world. I think it's more likely some new way of concentrated solar could have some niche application where it is advantageous, rather than competing with "conventional" industrial scale grid power generation. And, as we need a lot of energy as heat, better ways to collect and store heat energy might be as interesting as better ways to concentrate sunlight. maybe a phase change system, where a liquid is boiled in the receiver, and a gas carries the energy to the storage, both as latent and potential heat. Not only can that expansion "power" the heat transport, but it would also be possible to convert part of the heat energy to power.
One usage for the heat without turning it into electricity would be to make greenhouses in colder places, concentrating sunlight and storing heat for crops to grow even in harsh winters. And in hot climates, the sunlight can be concentrated to shade almost completely underneath, with the little light passing through being diffused by frosty/cloudy/scratched plastic to act like a neon which to give light to the crops below the mirrors. This would make the shaded areas colder/cooler, useful for growing crops, and maybe even useful for housing. And not only that, but large (meters/feet in diameter) pipes can be used to send humid air from the sea, through the pipes, reheated by concentrated sunlight, and released into hot-and-dry areas, ideally released close to mostly-shaded farmland.
@@jichaelmorgan3796 For the cost per kWh generated over the life cycle of the system, tracking became pointless, about 20 years ago, as adding more panels became cheaper about that time. The big reason is that solar panels are extremely reliable, over a very long time. Solar PV has become much cheaper, and better since then, so even if there has been significant development in electronics, solar PV has improved so much more. Under certain circumstances tracking can still make sense, as in when maximum output from a limited area is required, or if the mechanics can be made incredibly cheap somehow, like rotating whole systems of floating solar panels to track the sun.
@sergiy Could the wooden poles that you use to alter the seasonal height of the mirror, be replaced with upcycled umbrella shafts, which are disposed of widely but have a very useful telescopic function for this purpose? An estimated 1 billion umbrellas are broken and thrown away each year - this is enough to circle the earth 18 times, build 25 Eiffel Towers with the metal components, and cover New York City with the fabric. That means that they are cheap and widely available.
Nice Job. I wonder about the 'space blanket' which is a mylar sheet that is cheap but I don't know if it would last outdoors and remain reflective. Glass is durable and probably better (and washable). :)

Pressed metal mirrors, in mass it should be cheap, easy to weld mounting posts and any other necessary thing directly on them or just use bolts. Anyway mass production of base parts from metal sheets that get formed, including hands that hold the heat receiver should be cheapest while resisting heavy hail, very long life included. Also suggesting automation with Arduino like microcontroller and motors can used very sparsely with length adjuster when all is tied together with rope or metal wire, should find out the best motor power and gear ratio for cheapest option, very tiny and cheap motors could be used with very high gear ratio because there is no hurry. Special manufacturing line should make it very affordable in mass, motorized system should eliminate most upkeep cost also. :)
Not many companies developing solar power solutions are as focused on low total system cost to the degree you are. Only when solar is cheaper than fossil fuels will we make significant progress reducing fossil fuel emissions. Anyone who tells you different is selling you something. This is a brilliant idea. It could be used to create troughs as well as dishes, no?
Fossil fuels are a requirement. Mind you I love electricity. But recently I've had an admiration for people wanting to improve the engine side of things. If they're making promising, practical, and useful gains. I've in fact come up with certain strategies myself. Solar and wind.. both should be optimised for cost, practicality, resiliency, longevity and availability. So should engines. Engines are going to indeed be overrated for the poor performance they provide. And even more so when with slight.. minor improvements. I'm planning on making major improvements. Not to promote fossil fuel usage. But atleast if you're gonna use it anyways.. you might as well waste less. And get more performance. Wish this practically illiterate man ( me ) on his impossible endavour. And may he come up with something that may not be irrelevant.

@@jshaw4757 yes. Fossil fuels are also an economy stimulator. So whenever we buy it, we're stimulating economy. No matter how much the governmennte promotes pure electrical energy. EVs. They're gonna keep any new business or company from providing reasonably priced, low emission and reliable cars to the public. If some company does it. It'll surely be because of connections with higher ups. And they'll likely have obligations (or their own malice or greed) to ramp up the EV price from sustainable, widespread adoption.
What if you made a long pile of dirt with a parabolic cylinder impression? And mixed papercrete for surface stability? For reflective surface used a roll of aluminum foil lined beverage carton? Would love to see such setup. Cheers from 64 degrees north!
This idea could have an initial longer set up time but once you're familiar with the positioning of the sun throughout the day throughout the year you could just multiple mounds set up that way as it moves it constantly hits the next dirt mound therefore removing the need for any mechanical tracking?
Instead of glass mirrors, we could use cheap metal mirrors coated with transparent plastic. This would be cheaper to buy, but less efficient, so it might end up being more expensive in the long run, but tests would need to be done to get a better idea of their costs and efficiency in the long run.
Great video. I don't know how it made it to my suggestions but I loved it. I have invested into solar farm already purchasing 3kW but would definitely invest into some similar solution as well. Greetings from Lithuania and slava Ukraini!
The problem with mirrors/solar energy is the low value of efficiency and the high need for water, to keep the mirrors clean/efficient. Furthermore there is the problem to store and use thermal energy efficiently.
@@georgewashington1621 Ever calculated the efficiency of using compressed air? [-> thermodynamics] Mechanical polishing -> too much effort on big scale
@@michaelmueller9635 maybe you can use waste/residual heat to increase air pressure in a tank that was sealed at ambient pressure, then just syphon the hot air onto the mirror, the temperature of the air might help with cleaning effect.
You might want learn about JWST's design on focus adjustment, and since the target is big enough you don't need to pinpoint the focus that accurately. Also i wonder if it's feasible to bounce the ray thru a vacuum sealed window and heat something inside the house, double as indoor lighting. Also idea: use light tunnel mirror as light pipe.

I thought about using mylar space blankets, aka survival covers. They are 99.9% reflective, very cheap and I Imagine we could glue them to a slight reinforcement like a plastic sheet to keep a smooth shape and roll them down on a long stretch of concave formed dirt pile. Then we nail them down to make sure they stay put and put a long metal tube at focal length
i think what you propose may only be cost-effective on natural landscape which has already right orientation, facing south obviously, or may have rocky base. Moving land is not cheap and it seems like scale is what makes technology cost effective. I have sloped terrain where i will make use of your tech and let you know my findings. Here I would suggest to use rock instead of clay, which deteriorate under influence of water, snow, wind. Generally if the substrate is rock-based and shallow, an even probably cheaper option would be to dig a hole to the level where base rock is(lets assume its shallow roughy 0.5m) and use same material rock for creating wall/terrace. Definitely a tech which when conditions are met can be very cost effecctive but my assumption is its not for every and any cnditions.
The way I used to move my panels throughout the year - I mounted sixteen rigid 320W panels on top of a 30 cubic yard hydraulic dump trailer, I then rotate it with a mini backhoe and the trailer just pivots in place. If very strong winds or hail comes around, I can rapidly bring it inside the barn for protection. I have enough lifepo4 batteries to keep my refrigerator turned on for an entire week of overcast, aka shitty weather. Those strange windy/hail happenings only occurs once or twice a year. I am well off that I don't pay for any type of insurance - that money buys me more lifepo4.
I had simmilar idea - but instead of heat directly to stirling I thought of concenteating it in to reciever with liquid carrier and storage - then to stirling. This is completely managable even in local farm (optimized at least for 0.5 ha area). Thr key, however is having a atleast one smaller stirling that is used for just moving of oil/carrier liquid.
Yurko, I am interested in such solar based bricks with tiles. I would like to know how you made the concrete form. Any chance you could record the making of the concrete form? Thank you for your work. Юрко, меня интересуют вот такие солнечные кирпичи с плиткой. Я хотел бы знать, как вы сделали бетонную форму. Есть ли у вас шанс записать процесс изготовления бетонной формы?

What if I just heat up water in that tube, and connect the tube to a steam engine? 1) massive torque, which is most vital for electricity 2) much cheaper, because you produce more energy (less conversion) so no need to store it for night time
Crescent Dunes Solar Energy Project failure of this project Disappointed me but also solved many questions in my brain I would say mirror energy would be very much more suitable for warm water than 24h electricity due to high cost of steam engine parts ,heat storage plus maintaining effeciency and repairing cost. if that make sense I have seen low temprature stirling engine doing great job it should be working with medium water temprature from parabolic mirrors at least in the day hours.
So the goal is only heating a known thermal mass, id think that once this mass was to the target that means to insulate and maintain temprature would be of big interest. In vietnam we have vacumn solar heaters that are very efficient so having a thermal mass and a curculation of the cooler portion going thru the loop to be re heated. The bigger the mass the lower the variation and loss. Oil in a gravel mass the more dense the substraight the better. All say buried deeper would isolate from surface temps.
The reason you move the whole mirror isn't to just keep the focal point aligned with the collector, but also to maximise the solar flux on the dish. As the angle between the mirror and sun changes, the effective area of the mirror goes down, it is maximises by keeping the mirror pointing directly at the sun. I'd be curious to see how much this reduced efficiency affects your cost/kWh calculations. I'd expect it's still significantly cheaper to have an extremely low cost fixed mirror, though I can't imagine it would add much cost to build a simple frame anyway.
This problem was explored experimentally at the end of my previous video. 1 sq. m of a fixed mirror produces 2-3 times less energy than a moving one. Therefore, it should be 3-5 times cheaper (for example, 15 dollars per square meter)
As a Slavic person I feel very sorry about changing Ukraine culture... "Myrhorod" = Mir-gorod. Y = I H = G "Myrhorod" is not understandable in other Slavic languages, while "Mirgorod" is pretty easy to understand and do have etimological meaning. Slava rodu.
Так а шо по итогу? Вы планируете что-то еще делать? ну типа более менее сделать рабочую систему? Или вы больше про research&development? А производством заниматься не планируете?
just pour a concrete ground dish, instead of all that just use a soot blimp to collect hot air from sun. yep solar heat will float the blimp automatically and have minimum material per surface area and volume of hot air. there is no requirement for focus point and the hot air can be pushed like AC hot air flow from the blimp balloon ground attachment point fan. most of heat is used to heat houses and only part is used as electricity. there can be a blimp inner thin wall pipe to get the top side hot air pulled down to ac systems.
@yasirrakhurrafat1142 - Did you see the reciever shown at 4m25s?

@@christopherd.winnan8701 i think improvements can be made. I think I'm onto a stirling engine design that'd work quite well. I just have to make it. I don't make any promises.

My main concerns will be to keep things efficient ( I'll try ), keep the cost wayyyyy low, and have it be made from easilyyy available parts. Mostly just kitchen stuff.

I live in Shetland Islands where the winter is mostly dark, would it be possible to use solar power?! Many use wind turbines here but some people say those are harming wildlife. Plus they’re loud! Last winter we had a whole week with 0 electricity, there’s no gas here. It was very very bad, like in communist Transylvania where I was born. Electricity is also gotten more than twice as expensive, it’s almost as much as rent when it’s cold.
Try use a survey equip like total station to form the soil In. A parabólic form use geomesh or concrete barrer and try use a epoxy or polyster resin to seal the little pores , after use aluminum paper or use the diy silver mirror method to make the reflexión. 🤗
The long term solution for viable solar energy is to bring the Earth into a closer orbit around the sun. That can be accomplished by installing nuclear rockets/bombs on the moon to indirectly slingshot the Earth.
This is my favorite form of Solar Power. Hydro is my overall favorite, but you need flowing water for it, so it's not practical in most places.

This problem was explored experimentally at the end of my previous video. 1 sq. m of a fixed mirror produces 2-3 times less energy than a moving one. Therefore, it should be 3-5 times cheaper (for example, 15 dollars per square meter)
@@sergiyyurko8668 oh how cool! Thanks for the reply, and keep up the awesome work!
As a Slavic person I feel very sorry about changing Ukraine culture...
"Myrhorod" = Mir-gorod.
Y = I
H = G
"Myrhorod" is not understandable in other Slavic languages, while
"Mirgorod" is pretty easy to understand and do have etimological meaning.
Slava rodu.
What are the components for the oil used to absorb the heat?
Так а шо по итогу? Вы планируете что-то еще делать? ну типа более менее сделать рабочую систему? Или вы больше про research&development? А производством заниматься не планируете?
Nice !
Earth/cement mixture could be used in the same way as compressed earth blocks are made.
Good stuff my dude
great idea
welcome back :)
can you tell me where i can get a sterling engine like that? the only ones i can find are toys.
So come on over and help to start it up!
the downside of this is that u get no tracking system. I think the antenna option is still better because it allows for the tracking system
just pour a concrete ground dish, instead of all that just use a soot blimp to collect hot air from sun. yep solar heat will float the blimp automatically and have minimum material per surface area and volume of hot air. there is no requirement for focus point and the hot air can be pushed like AC hot air flow from the blimp balloon ground attachment point fan. most of heat is used to heat houses and only part is used as electricity. there can be a blimp inner thin wall pipe to get the top side hot air pulled down to ac systems.
Try carbon fiber cloth solar collector hot air balloon
tres bien !! merci
Mirror manufacturers cannot see this demand? Why so artisanal?
What method do you utilise to extract the energy from those parabolic mirrors sir?
@yasirrakhurrafat1142
- Did you see the reciever shown at 4m25s?
I reckon that this could be improved considerably by using a conical helical spiral, which would increase the pressure of the water as well as the heat. Still, such a device might be difficult and expensive to fabricate. Can you suggest any effective alternatives?
@@christopherd.winnan8701 i think improvements can be made.
I think I'm onto a stirling engine design that'd work quite well.
I just have to make it.
I don't make any promises.
Would you wanna see it?
It could really take me some time.
My main concerns will be to keep things efficient ( I'll try ), keep the cost wayyyyy low, and have it be made from easilyyy available parts.
Mostly just kitchen stuff.
Although.. you may need to buy some things, like bearings.. and some other.
But.. I'll try to keep it as accessible as possible.
@@christopherd.winnan8701 ohh btw.. yes. The shape you mentioned.. would definitely see improvements with more efficient shape to absorb the heat/light.
@@yasirrakhurrafat1142 How about upcycling an old fridge coil. Those are pretty cheap and widely available. Maybe upcycle old biscuit tin to use as an enclosure. I know that a fridge coil is not helical, but it might be useful to get some base performance readings.
@@yasirrakhurrafat1142 I am working on another project that is repurposing a couple of old umbrellas. Could I contact you to get your feedback on that one as well?

I live in Shetland Islands where the winter is mostly dark, would it be possible to use solar power?! Many use wind turbines here but some people say those are harming wildlife. Plus they’re loud! Last winter we had a whole week with 0 electricity, there’s no gas here. It was very very bad, like in communist Transylvania where I was born. Electricity is also gotten more than twice as expensive, it’s almost as much as rent when it’s cold.
I think wave power is more interesting in your case. But its not individual devices.
I think you should raise the price for mirrors
I was thinking that most chip bags or similar could also be used as free reflectors, has anyone tested this?
Don't forget about the wind blowing😊
If solar power have future, only inflatable construction.Because most cheapest
Try use a survey equip like total station to form the soil In. A parabólic form use geomesh or concrete barrer and try use a epoxy or polyster resin to seal the little pores , after use aluminum paper or use the diy silver mirror method to make the reflexión. 🤗
Approximately how much heat it will produced ?
About 2 kWh / sq.m per one sunny day
The long term solution for viable solar energy is to bring the Earth into a closer orbit around the sun. That can be accomplished by installing nuclear rockets/bombs on the moon to indirectly slingshot the Earth.
stop drugs
use black surface to get more heat on reciver
TIPA: The Future of Solar Energy, Today. Доброго дня. А ви щось вже розказували за цю тхнологію?
Great
This is my favorite form of Solar Power. Hydro is my overall favorite, but you need flowing water for it, so it's not practical in most places. When I have my own Home, this is how I plan to heat my air and water along with being one of my sources of electricity. I will not be on the grid- Society sucks harder than an industrial shop Vac, harder than anything imaginable, besides society itself. I look forward to disappearing and being forgotten.
I don't know how to build the reciever and convert the head into energy.
Перевірку градом пройде?)
You can make it with cement

Instead of concrete why not try sodium silicate mixed with the earth?
Is sodium silicate cheaper than wood ash?
@@christopherd.winnan8701 Don't know. Might get better results with the silicate, but for sure you can never beat free. Be a matter of what are the results and which lasts longer.
@@johnmcginnis5201 Good point.
1m2 mirror can boil water, same solar power make 100w
شكرا جزيلا
Сергей. Помогите посчитать. Я пытаюсь посчитать систему. Я хочу сделать подземное хранилище воды, обложенное пенопластом, и летом через солнечный коллектор загонять туда тепло.
Первый параметр сколько мне потребуется кубов воды, для круглогодичного отопления дома? Для этого мне нужно понять сколько Киловатт тепла в одном кубе по разнице температур. Получается минимальная температура для меня это 40 градусов для теплых полов. если я нагрею воду до 80ти а может и 90 градусов, сколько мне нужно воды, чтобы отопить дом 100кв метров и СИП панели, энергоэффективный, в южном регионе в Киргизии, наверно даже теплей чем в Украине.
А потом уже посчитать сколько квадратных метров зеркальных панелей мне понадобится чтобы нагреть эту воду за летний период.
Помогите мне найти нужные формулы пожалуйста.
