How to make solar electricity 2-3 times cheaper
HTML-код

- These mirrors focus solar radiation and convert it into steam, and I do a lot of experiments with different types of mirrors to find the best type which can convert solar radiation into thermal energy at this cost, 0.5 cent / kWh, and it is about 10 times cheaper than heat from natural gas. Such a low cost of our solar heat allows a turbine to produce electricity so cheap that it wins competition against thermal and nuclear power plants, and combining the following three ideas could reduce the cost of our solar electricity by several times additional.
The 1st idea is used by these large solar power plants which convert solar energy into thermal energy with a temperature of almost 400 ⁰C. My previous videos have often described how this thermal energy generates electricity using a turbine and similar heat storages which allow the same turbine to produce electricity at night.
Our 2nd idea is also well known, and for example, this solar station has been in operation for 10 years, and these solar collectors heat water at 50 ⁰C, which is used to produce copper. Now I am showing another example, in the desert, and here we can see many mirrors that convert solar radiation into steam, which is used to extract oil. This is another example, in California, where many mirrors heat vegetable oil above 200 ⁰C to produce snacks. In addition, we can find several hundred other examples where solar energy is converted into thermal energy which is used for industrial processes in the food, textile, chemical and other industries.
Our 3rd idea is also well known and used very widely, for example, this solar station, which heats thermal oil to over 300 ⁰C. This energy is spent on the simultaneous production of both electricity and thermal energy to heat water (for district heating), and engineers call this simultaneous production of electricity and heat by this term.
So, let's combine those three ideas with similar mirror systems that could give us huge amounts of very cheap thermal energy. We understand that similar low-cost mirrors must cover many square kilometers, and therefore their power can be comparable to nuclear reactors. Their thermal energy heats a huge amount of substance inside similar heat storages to a temperature of approximately 300 ⁰C, and one of my old videos showed many types of heat storages made from concrete, gravel, sand and other cheap materials. This hot substance produces steam for a turbine not only during the day, but also at night and on non-sunny days. The turbine not only rotates an electric generator, but also releases a huge amount of thermal energy which is not emitted into the atmosphere, but is transferred to some factory.
Now I will prove why the sales of that thermal energy can reduce the cost of the electricity several times.
Let's assume that we do not sell the thermal energy, but emit it into the atmosphere, and let the cost of our solar heat not be 0.5 cent / kWh, but 4 times worse, 2 cent / kWh, which is written here. This case leads us to this very bad cost of our solar electricity. But now I take into account the sales of our thermal energy to some factory, which are added to our formula in this way. We see that these revenues from the sales have reduced this cost of our solar electricity by almost 3 times, to the level of 5 cent / kWh. Now we will compare it with the first formula, and we see that the 2nd formula takes into account these revenues from the sales, but it is well known that the sales will noticeably reduce this turbine efficiency, and also slightly change these values.
It is obvious that such effect of reducing the cost of our solar electricity will be different for different cases, and for example, let's consider the case of solar power plants of this type. If the heat sales are not used, these power plants lead us to this cost of electricity. This is the same case, but now we sell that thermal energy to some factory, and the sales are taken into account here.
Let's compare these two formulas, and we are surprised to see that those heat sales do not reduce the cost of electricity, but on the contrary, increase its cost. Of course, these heat sales revenues reduce the cost of electricity, but other causes increase its cost. The main cause of the increase in the cost is the decrease in this efficiency of converting solar energy into electricity. In addition, the cost of electricity increases slightly due to the decrease in this capacity factor and the increase in this value, although improving this energy block cost slightly reduces the cost of electricity.
Nevertheless, let's pay attention to this selling price of our thermal energy. It's obvious that increasing this price reduces the cost of our electricity, and for example, now the increase in this price of heat has led to a decrease in this cost of electricity by 1.5 times.

The same information over and over again. if you make a new video, improve upon previous videos, dont just reclycle the same things.
Pour apprendre il faut répéter le même sujet, nous avons tendance a avoir une mémoire d'une mouche a fruit.
I really appreciate all the work you do.
....Like i have said before.....you are repeating yourself to much. When you will start to convert your ecuation in somenthing usable? Theory ist more then enough on your channel...please do somerhing also with your formula ...convert it into reality.
Please understand my comment in a positiv way!
All the negative comments are from people who can't produce a decent video of their own.
Здоровля та успіху у вашій роботі!
appreciate your work bro
Great man working for Humanity ...
Sergio, I am working on using this system to manufacture cheap pool heaters for Australia and the American south west.
Can you make a video on how to make this in our homes? If you had already made it please please tell where we can find it.
Love your work!
If you operate your turbine system under vaccum, you can also lower the boiling point of the fluid (water or other) Check out Charlie Solis's channel, for a tesla turbine system that can efficiently turn the heat energy from your mirrors into electricity with a proper, high surface area tesla turbine...
But what about the construction and maintenance costs and viability of the energy transfer infrastructure required to make it possible for a random home to sell it's heat (energy)? I know electricity can be sold off to the energy grid but heat???
Это одно и тоже.
The trick is to try and make each process minimise the increase in entropy.
Nothing new so far. Do you keep repeating the same information, or am I wrong?
Excellent.
Nah this youtuber has come with nothing new since the war, with good reason but these videos are just the same as earlier. And the design isnt that good as he has not yet got a cost effective system that people would actually consider. I still love you Sergiy
Maybe you can do better than him. Let's see your videos. Its very easy to be keyboard warrior.
@@drrohitchaudhary7537I thought exactly the same! 😂
@Sergiy Yurko, what do you think about a hybrid solution consisting of a photovoltaic system, a thermal battery and biomass?
Heh. How do you think to integrate biomass into the system?
@@intellectualcat4000 Photovoltaic system that has two functions: produces electricity for the grid and uses the excess electricity for heating a thermal battery to high temperatures. Thermal oil passes through the inside of the thermal battery, which produces steam in a boiler. This steam rotates a turbine. When the thermal battery cools down, the steam in the boiler will be produced with the help of biomass, either by gasification or by direct combustion.
@@MrDilauc I thought you wanted to pass light through an aquarium with algae, and then focus it on a photocell)
@@MrDilaucusing excess electricity to heat a thermal battery = inefficient and uneconomic.
All good info. It's just that most have advanced to solar heat prowering a Sterling engine is more efficient. Sterling engine with either 4, 8 or 16 cylinders .
Sergey, it's winter now. Please make a large lens out of ice. I would really like to watch a video of this experiment.
That is a lot of electrgcity!
Get a better robot voice...
Hey from Australia Sergi, I been watching yr posts for some time and I've always wondered if in the beginning you had a home made turbine/generator or if you purchase one?
Going with your simple set up I can easily see how someone could possibly store or use the heat in their house without electricity however I'm curious about the simplest way to generate elec.
This is the difference between theory and practical applications.
Dzień dobry, w nocy i o północy. 🎉
As always, great content. Thanks
This guy is so friggin awesome
Any MVP plans?
The only thing I have against using a traditional steam turbine is that you are using up precious freshwater (I guess saltwater would destroy the turbine pretty quickly), and emitting it into the atmosphere which would create a greenhouse effect.
Vaporizing water doesn't contribute to greenhouse effect. Plus you can have the water of a steam turbine in a closed system.
Check out Charlie Solis's channel... He is designing an optimized tesla turbine heat to electricity combined heat and power system that could absolutely run off of the heat from sergei's inexpemsive solar reflector/collector systems, and should run fine with filtered sea water.
@@orcoastgreenman Thanks, I'll look into it!

Only put it on your own roof, let nuclear, gas&coal cheaply take care of the rest.
Hi Sergiy! I was thinking about using solar and massive heat storage to boil ocean water, spin a turbine if needed, but the remaining steam to be channeled up by pipe into a giant water tower built like Taipei 101 to rezist storms and quakes. The tower itself can be built on top of a neighboring mountain. The goal would be to take the steam as high as possible and run it through a passive radiator at the top. The colder upper atmosphere would be more efficient at cooling the steam, no pump needed to get the steam up there, and once cooled down, the water can be fed by gravity as far as we want to, as long as the elevation of the terrain is lower than the collection basin in the tower.
Using natural phenomena of rising and condensing steam and falling water for passive or minimal intervention desalination and water distribution, like the roman aqueducts.
Also the resulting brine can be made at high enough concentration for mining lithium or plain salt. The fresh water can be used to irrigate deserts, maybe a plantation of Jatropha Curcans (edible variety that uses minimal water and soil unfit for agriculture) that would make a carbon neutral biodiesel, the remaining pulp would be great animal feed, the resulting animal excrement can be used as fertilizer and soil building.
What do you think?! Would this be feasible?!
I like your awesome imagination and engineering knack.
Have you heard of the sky window
A portion of the infrared spectrum goes through the atmosphere without interacting with the air and goes straight to space. You could cool the steam and use a radiator coated with a paint or other coating that radiates heat in the wavelength of the sky infrared window
The issue with desalination is that stuff that's dissolved in water also evaporates with the water, but not all of it. This means you end up with salt to clean up and if u don't then if u keep adding water eventually it will be a brine and then even more salt can escape in water vapor. I think there are already plants using distillation though. Its always a cost issue. Humans have never been able to build exactly what was best. Its a challenge of weighing the cost, and if there will be better technology to do the same thing later. Just like how people have to save money or take loans to buy things like horses or cars or even smaller things. If you are able to pay more upfront you usually can get better deals on stuff or better quality of stuff.
A great example is the samuel vimes boots theory of economics.
If humanity could afford to do things like create green energy, infrastructure like water desalination, electricity, transport agriculture
Capitalism doesn't provide an answer to these problems either. The great works is one example of a time when we were able to invest money into things that would help many people for a long time but they are getting pretty old.
Unfortunately the great works happened right before capitalism was allowed to take over in its present form. Corporations now hold more liquid assets than the federal government. They won't build infrastructure because their business model relies on utilising publicly funded infrastructure to do their business. This is why so many people are on welfare yet work for a corporation. It's better for them to pay their workers so little that they can receive welfare. If the government would insist that they pay enough for people to not need welfare the companies start crying and threaten that it will lead to the loss of jobs. Corporate America is nothing more today than a system of legal theft (that is the theft of resources taxes people land and water) lack of morals and cultural stupidity. It is more popular to make profits above all else that they are now willing to actually extract wealth from humans by buying their blood plasma, cataloging dna sequences and selling them to the highest bidder, and destroying the nation's capacity for food production.
Rant
Theoretically, building blocks can be made from salt. In any case, we must return the salt to the sea in a closed form to reduce the salinity of the water.
@@intellectualcat4000 if you put the salt back in to the sea you are increasing salinity. This is why I proposed mining it. It will increase the profit margin and will keep the salt out of the sea/ocean, this way we combine the environmental goal with the economic interests.
You can’t use sea water the turbine blades would collect the. Solids in the water
@@andystone9265 You can distil the sea water and use the distilled water 4 the turbine. Also you can make a closed loop with distilled water that on one end spins the turbine and after existing it preheats the sea water for the solar desalination, like a sterling engine. There are different ways to do it. The part that interest me is the water production and distribution over large areas that are not usable at the moment. The rest are just economic aspects that could entice investors to create such a system.
damn chp 🟥
