How mirrors can generate cheap solar electricity to end coal and nuclear power plants

- This is one of my experiments, and a large number of these mirrors focus solar radiation in this way. Here we see thermal energy which can be used to generate electricity, and later I will describe how it is usually done through a turbine by these large solar power plants with millions of square meters of mirrors. However, these mirror solar heaters are very expensive, and therefore they produce expensive electricity, but our solar heaters are many times cheaper.
So, this is my next attempt at finding a cheap way to convert free solar energy into electricity, and my goal is the victory of cheap solar electricity over thermal and nuclear power plants. Our idea is based on such mirrors on the upper surface of similar concrete slabs which are commonly used for garden path, sidewalk or covering large areas.
A variety of companies produce concrete slabs that are durable and cheap, and technologies for their installation have been known for many years. Moreover, we can meet similar machines for automatic concrete slab laying. It is obvious that these machines drastically reduce the cost of installing concrete slabs and allow us to cover large areas with slabs quickly and efficiently.
Here we see spots of solar radiation from each of my mirrors. We see that the spots are trying to unite at one point, where a similar receiver should be. Such receivers must heat some kind of liquid heat transfer to a temperature of several hundred degrees, and this thermal energy is used to produce electricity.
It is obvious that our paths of mirrors must form such long rows. The principles of such rows of mirrors are shown by me in this primitive example. Here we see several receivers of one short row, and, for example, this receiver is the focus point of the solar radiation of these mirrors, but it is obvious that there must be several hundred mirrors here, and this width should be several meters.
I should clarify that my experiments use such concrete slabs with multiple mirrors. At the same time, such slabs with one mirror seem to be cheaper. The cheapness of our concrete slabs is very important because we should strive to reduce the total construction cost of our mirror covering to the level of 15 $ / sq.m. This total cost seems realistic because the cost of components for our concrete is approximately 2 $ / sq.m, and the cost of different types of mirrors can be several dollars per square meter. The total construction cost of our mirror covering of 15 $ / sq.m results in this cost of our solar heat, 0.5 cent / kWh.
This is that total cost of our mirror covering, and we understand that if it exceeds $15, our solar heat will still be very cheap and approximately 10 times cheaper than the cost of heat from natural gas. If we have already reduced the cost of our solar heat to this level, 0.5 cent / kWh, we can turn it into cheap electricity at 5 cent / kWh, and now I will remind you how the thermal energy from such solar heaters is converted into electricity.
When the sun appears, its radiation 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 such heat storages, where the energy heats several thousand 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.
In addition, my previous video described this heat storage based on cheap gravel rather than expensive molten salt. These gravel heat storage can accumulate thermal energy not only for the coming night, but also for several non-solar days in a row. Moreover, we can charge our gigantic heat storages with summer thermal energy, and they will store it until the winter months. That is why our solar power plants can be independent of the weather, and work just as well in non-solar winters as they do in sunny summers.

How exciting. I have always wanted to make a similar set up. Can't wait to see it 👍
so far unsung ...
yet A Hero
and I'm honored to watch your work
thank you
For creating a parabolic mirror you could use a stainless steel sheet, with laser/water jet cut slots and holes. The flat sheet would the be flexed into shape and rivets placed through holes to hold sections in place.
Always so intresting, energy and heat. GOOD work Sergey! Thank you for more uploaded Videos here! I Wish and Hope You and relatives are ok!
Hats off! And take care Sr!
Fantastic as always!
Firstttt!
Glad to see you're still okay man!
Alright, first i was wondering if you could do some videos on the receiver (where you concentrate all the solar light?) that would be so nice!
A complete tuto on a basic installation, and maybe how to hook up in series would be great as well!
Also if you have any numbers more numbers you can provide us? That would be awsome!
(how many watts did you save using that system? How much time were you able to have heat? How many time you couldnt? What were the numbers of sunny days? (and overall position so we can extrapolate for maybe others users?)
What would u different if you were to start from scracth?
I can also recommand a fundraising in order mayne to devellop the idea more? And try more things, do more tuto, maybe join some lowtech communities?!
Thanks for the video man! Wish you the best!
Nice design 👍 Great work man!
I think this one is the best yet.
Excellent job on another great video 👍
Happy you are doing well! Another interesting video! Thanks/Tomas
Very good idea
Amazing...
Simplemente naravilloso. Yu are the best. Your videos are amazing. Next time i will write in spanish. Bravo!!!
Very good thank you!
Very nice innovate ideas 💡
Amazing like always 👍👍👌👌
Very nice 👍
Thanks
sergiy, thank you for your work, i have an idea, solar thermal collection>sand thermal "battery">stirling motor/heat exchanger>electric batteries.
wish you and your family and friends well.
Idea:
1) Build rotating platform.
2) Pour concrete in a round form on it while it rotates.
3) The centrifugal force will create a parabolic (?) concrete slab.
4) Then cover it in reflective material like the foils you used or pour on some mirroring solution
Some smoothing is probably required. Maybe one needs to use a material other than concrete that creates a smooth finish or cover the concrete in filler and sand it.
Good idea for the small buisiness.
It would be simpler to cut steel sheet in the shape of the required parabola and use it to screed wet cement into that parabolic profile.
@@fleaniswerkhardt4647 Is there a liquid, like a paint, which has the reflective qualities needed? Just paint it or pour it on the curved surface.
@@markhathaway9456 if a concrete mold is used and the top layer is made completely smooth with a fine mortar mix then a reflective Mylar layer can be glued to it.
Sergiy, I will be interested in how you made the backing material for the mini mirrors. It requires a certain level of precision placement to acquire focus correct?
Can you do a mini ebook to build this🙏.
Good, but only works with collimated / direct sunlight, not diffused light. You can not focus diffused light
I love how you singlehandedly debunk that one mythbusters episode :p
Greetings from Egypt.
Your expirement is very useful here in Egypt.
We have a very hot sun 365 /year we dont have fog 3 days /year.
We have a too long distance of diserts
Almost you need egypt 😁
Be aware the reflective film I got went transparent after three years. So factor that in.
For the grass near the mirrors, You can throw salt or mix salt with the dirt so nothing grows near, or some sort of chemical like acid. Or you can place black gravel which also works, or a cover of plastic, or cement.
actually Grass can also help to cool down the slaps
Very good seryur, mirrors are powerful instruments, the james web tele is supposed to see 100 million years after the bb, what ever that is, about 13.8 billion years ago, according to human estimates, anyway, your insight revealed to us, will help continue your plan, free energy for all, thank you>
Найдешевший варіант сонячної системи, який я зміг придумати. Викопати в землі параболічну форму, встановити туди дзеркала, сфокусувати, накрити плівкою від дощу і снігу. В якості приймача використовувати залізну трубу вигнуту за формою руху фокуса, хоча трекер був би краще.
i just hypothesized your skewed focuses because mirror not first surface and have thick glass, my suggestion try 2 mm common mirror or blank glass covered by adhesive mirror
Hey Sergiy! Have you seen the TED Talk with Bill Gross? I think he found a great cost effective solar solution.
How did you make the collector?
What is the angle of the mirrors?
The covering of building with a mirror.. well search "UK building melts cars" There was a High rise in London that was acting like a mirror.. I feel that thing is not going to work :) Great work btw.
Do you've an steam engines you can recommend for power generator?
Excelente job , very anxious waiting for diy video .
It can work as desalination?
If it can turn water into steam, why not? But one should not vaporize salt-water in the receiver, as the salt would stay there until it is full of salt. So you need to transport the heat from the receiver to the vaporizer and that is where it gets complicated.
@@hschmidt79 Hi Harry , you are right, the solar heater is for pre-heater, and then goes to the destiler, any comment welcome
I love these videos but please note $ goes BEFORE the amount as in $1
Why not try putting a magnifying glass in between the mirrors and the point where the heat is collected to give you more intensity?
Could you please Test it with sand as heat storage?
Just an additional video about biomimicry from Michael Pawlyn very interesting topic it's a video under 20minutes. .
Maybe the wall would be parabolic or hyperbolic
Can Tesla turbines be used in conjunction with the concentrated solar heating of water to steam?
Water under vaccuum can boil at much lower tempratures...
Mirrors should be placed on a parabolic surface. This is the law of geometric optics! You can make this surface flatter if you raise the focus of the mirrors, or if you cover all the mirrors with glass for a walk.
Hello from Romania, Sergiy. I think you are focusing too much on the heat production (you got that covered already) and too little on the production of electricity from that heat. How do YOU extract electricity from your boiling water circuit (I presume yours is with water)? It will be good to focus your videos on heat storage and conversion to electricity! Good luck.
Sergiy seems to have an endless stream of ideas about reducing collector costs. Amazing. I found a household scale steam turbine available from Germany for $10,000. The costs need to come way down there. I would love to see Sergiy steer some of his great creativity to that.
bạn đã ra mô hình mẫu phát điện 24/24h chưa ?
It's already being done , very efficiently there is 4000 kw plant in India
That's a bold goal, to end nuclear energy. Good luck with that.
Queste tecnologie sono state superate.
Ci sono innovazioni molto semplici per produrre energia elettrica e calore 24ore su 24.
I di può realizzare qualunque potenza in spazi ridottissimi.
Faccio in esempio:
50mq. Si possono realizzare oltre 100 Mw.
is anyone else wondering how a PV which needs 1km long clean room production facility has been developed but no cheap metal / plastic, mirror turbine system that can be built in low tech factories exists? is the engineering of such a system really damn difficult considering we have gas / steam engines for centuries and all they require is a mill?!
Solar thermal really makes sense when you can use the electricity and the heat produced so the steam cycle efficiency is not a limiter. Then it beats PV hands down. If you cant use the low grade residual heat then application of solar thermal is more limited and less astounding.
Have you considered gluing the small mirrors to a tarp or similar soft material?
Maybe that way, you could tie a rope to each corner of the tarp and adjust the position and curvature of the mirrors to better focus the reflection during the day.
Your solar collector ideas are great! Can you also talk about turbines to make the electricity for a house?
look at Tesla steam turbines, you should find some useful small sized power plants that are easy to make.
You might enjoy the large sterling engine scheme of Tamera village in Portugal which produces electicity from heat collected in thermal oil.
See the Stirling design Tamera uses @1:40 min to produce 1.5kw with the stored heat.

A sheet of Mylar would be even cheaper
When you'll move to turn your trials to solid enterprise (company for example), you also need to turn what you do to open-source for others to add to your experiment until something solid is created.
Put your contacts for others to help you and themselves to reach a break-through to energy slavery all world around.
Appreciate your knowledge and skills.... if you want to earn money on RUclips, then continue what you do..... but if you want to change the world and make others build something that will work locally in the global world, a more "complete setup" guide would be needed... a lot want to "make a change", but no one knows exactly how to do it (not everyone can add intelligence/sensors/movement/systems etc. to continuous harvest the sun while it moves...and thereafter convert the thermal power into either electricity or "heat exchanger" setup for e.g. hot water)
How do you calculate the mirror position?
Remember that with the changing of the seasons the sun will be shining down at right angles (90 degrees) between positions 23,5 degrees north an 23,5 degrees south. Like this: on december 21 the sun is directly over 23,5 south, on march 21 the sun is directly over the equator, on 21 june it is over 23,5 north (summer solstice for the northern hemisphere)
At this date, 90 degrees north of the equator, at the north pole, the sun is seen above the horizon at…23,5 degrees! When you travel south from there to Sergiy who is at 50 degrees north you have to add 40degrees to those 23,5 to find the max solar elevation for 21 june at his place: 63,5 degrees.
@@Calligraphybooster And how do you calculate the angle of each small mirror on the slate
@@MestreBonsai the passing of each day makes the angle of the sun vary between 0 degrees (at dawn and dusk) and 63,5 degrees at noon (that is not necessarily what you read from your watch; it is true sun noon) on june 21.
For the matter of maximizing efficiency I would want my mirror set up to make best use of the sun between 21 March and 23 September. At these dates the sun is 40 degrees above the horizon at Sergiy’s. The average of 63,5 and 40 is about 52 degrees. Therefore I would erect an earthen mount with a slope at 38 degrees to place my mirrors on. It must run true from East to West.
Next I would make a temporary support construction over the mount that runs North-South, and would mark the point on it where I want the future collector to be: the same position as the average seasonal position of the sun at noon. That means at right angles with the surface of the mount and halfway up the slope.
You asked me how I would calculate the positions of the mirrors. From this point on I wouldn’t. I would lay out a square grid on the mount where I need my mirrors to be placed. Next I would stick a lump of clay in the place of the future collector (the average foacal point) and, if I had one, fix a small laser pointer to it, pointing down on the grid on the mount. Then I would place a mirror on that spot and manipulate it until in shines straight back at the source.
Without a laser I would use a wooden cube with a long pointing rod to press the mirror in position while the rod points to the collector.
More about the position of the sun for any given date/hour and position you should be able to find googling. Use terms like ‘tables astronavigation’.
I hope this was of use.
@@Calligraphybooster Thank you very much for this very complete answer.
I was thinking of doing that :-) thought there was some other way 🙂Thanks
