they show these shots of it burning, naturally, it looks very scary, and people are afraid of it, but in fact, hydrogen - when it leaks, it evaporates, it is a very light gas, it accordingly rises up and practically does not concentrate below us, where we are, in my opinion, in this case, hydrogen is even safer. later we will have other oceans, but already in the second part of our today's investigation, research. pentalgin - remedies for different types of pain. pentalgin works against pain, wherever it is, regardless of the reasons for its occurrence. pentelgin, we will do without pain. still thinking about the ideal home? it's time to switch to dom click to buy an apartment in a new building or secondary market or build your own home on a mortgage. on dom click everyone will find housing for themselves. do you hear?

smart officer named shelishch, he first came up with the idea of ​​no gasoline, he came up with the idea of ​​removing the elevator winches around the house, they removed the elevator winches. they put them in position, a few days later there was no electricity, a dead end, then lieutenant shelich came up with the idea of ​​filling the one-and-a-half-ton truck with hydrogen, he started the engine of the one-and-a-half-ton truck, the engine started, then it blew and there was an explosion, and he realized what had happened, a spark had passed from the engine into the gas tank, so it was necessary to interrupt the path for the spark, how do the toilets work there just like we do, excuse me? there is a water seal, such water seals were removed from fire extinguishers, today everything is even more interesting, that is, the near future on you take energy, essentially from the air, wind, split water, hydrogen, and burn this hydrogen to generate electricity,

we do not burn it, we transform it in fuel cells, if you allow me , i want to explain in a few words that here we are not talking about the literal combustion of hydrogen, which means in two or internal combustion, this is chemical reaction, it happens like in a battery , which is on any car, we have two electrodes that are separated by an electrolyte, the only difference, the fundamental difference between fuel cells, for example, and batteries, in batteries we have the fuel oxidizer actually inside the device itself, here we supply the fuel oxidizer from the outside and this ensures at...

hydrogen was a waste of this production. and where to get hydrogen today? in one of our previous materials from ur, from the city podchevstro. we talked about the local university and showed the world-famous laboratory of dmitry besarabov located there. and it is just a wire. i think that depending on the specifics of the country, some technological solutions will be more acceptable for one country and less acceptable for another. for example, in the south african republic, where i work now, the emphasis is on the use of solar energy, while russia is rich in natural gas. dmitry besarabov needs to be explained, he nobly proceeds from the fact that you can decide for yourself, what method of hydrogen production to choose, for example, blue from gas or green

by electrolysis, and with alternative sources from water, for understanding from easter island, in theory at these latitudes this is just an ideal condition for the production of green hydrogen, the wind is constantly blowing. sun, one problem here on easter island, specifically the water shortage, catastrophic, if it accumulates only there in this crater at the bottom of an extinct volcano, but in other neighboring countries there is an abundance of water there, but no, not only there, that's the thing, yes, yes, even in our last film from the series "world watershed", when we flew over dried-up reservoirs in africa, well, i'm flying over an abyss now, under me is an artificial scalypt forest, which is now almost dry. of course, such a strong word as hypocrisy was used. to understand, on the atlantic coast in namibia there is enough sun and wind, but there is a desert all around. so the germans set up a desalination

plant on the ocean shore, the water from which, however, goes to their plant, and behind the fence even the grass won't grow, that is true, it is white coal, i am retelling this article to someone who, as we have heard, is in favor of alternative energy sources, here is an unexpected turn in our conversation with experts from the developing world. this is fair, i know that this is a political issue, well, excuse me. it is not a problem for me to talk about this, it is clearly unfair, i have no doubt, but the fact is that the world is unfair, what is happening everywhere? i will not even dwell on namibia, what is happening everywhere, we we continue to see that we are in an eternal struggle for resources everywhere, the world is unfair. well, let's listen to the one whose father adapted hydrogen to the needs of besieged leningrad and at one time headed the russian national association of hydrogen energy, business is business, for it the criterion of the main

profit is always, what you are talking about now, the need for water, not only namibia and many countries, this is the business of states, from my point of view, uh, well, maybe we have not yet matured humanity, but this is of course, the business international community, the russia africa session on water use, which was opened by deputy prime minister dmitry patrushev, here's what else ours: the global energy association held at the st. petersburg international economic forum this year, at our big session in st. petersburg with the participation of deputy prime ministers and ministers, energy curators, we tried to make sure that everyone heard each other. however, in russia itself there is much more room for maneuver, we have competitive advantages on the topic of hydrogen near the shores sakhalin. lots of solar radiation, lots of sun, lots of wind, there will be a lot of water now, but the competitive advantage of our coast. is that the water is not only salty, there is pressed water, where-where in such

a rich rivers, lakes country as russia, about what can be done with water wisely, there is something to talk about, if you dream, and not hydroelectric stations should be the main place where hydrogen is produced, i absolutely agree, this is entirely green energy, moreover, it is cheap electricity, and accordingly, the generation of electricity... for hydrogen, well, it just suggests itself, well , where there are hydroelectric power stations, there is automatically water, so here you have electricity, here you have water for hydroelectric power, yes, this is the topic that can definitely be developed in russia, yes, based on hydroelectric power. what can you say about the prospects of the hydrogen economy? i believe that this direction must definitely be addressed, today there is still a hydrogen economy, compared to other energy sources, there is no economy there yet, not yet, not yet, but everything can change, therefore. as soon as the hydrogen economy starts working, we must have time

to quickly enter with our technologies, sovereign technologies, and implement this process project. here in sakhalin they want to experiment with hydrogen production and so does edek, especially since there is so much gas on the shelf, and the shelf can be explored in more and more new ways. this is also a hydrogen drone. but in sakhalin they are now very actively developing the topic of flying drones-copters, and sea drones. well, let's start the experiment, so, probably, yes, oops, and now it will fly itself will start living its own life. let's go, where if not near the water, still ask about green hydrogen based on water. where will you get water from? well, look, there is enough water, because we take it from wells. don't touch the rivers. no, we do not have leafy rivers and we try

to get by, although there is plenty of water, but nevertheless it is smooth, yes we check again lower vertically, so we have now passed several very nice rivers, there are fish there and what exactly will you take water from these rivers for hydrogen, earlier we took water from the river to cool our mechanisms, but we encountered certain problems from environmentalists and the fish industry, of course, the first thing i thought was, what is the solution? we drilled an artesian well, received the appropriate permission, and now we will take water, including for the production of hydrogen with a sludge. on the one hand, it may seem that such a careful attitude to water is something completely new for russia, but at least it was formulated 100 years ago in the book "white coal". the costs of hydraulic structures for power plants are largely justified in cases where these structures can simultaneously serve to improve navigation. come on, just navigation. from the completely exotic cherkey hydroelectric power station in dagestan they drive sheep, along hydroelectric power stations such as volzhskaya,

saratovskaya, uglicheskaya, paved roads, and even railways, that is, these are both power plants and bridges, well, and also ready, this track for rafting competitions was also built based on the experience of building hydroelectric power stations, actually it and located at the hydroelectric power station (gas) on zagorskaya, and soon there may be more on the topic of the hydroelectric power station. a lot of new things. at the july ceremony of announcing the names of the laureates in the global energy prize , the names of the winners in the non-traditional energy nomination were announced. this year, the first latin american in the history of the award, a quertar rican, hector obrunia in the nomination of new ways of using energy mingau, ouyang from the people's republic of china, but there was a moment when we remembered the visit of members of the international committee to the largest volga hydroelectric power station in europe and the one located behind it volzhsky branch of the moscow mii, when the global energy guru presented a project for the construction of a new channel that will give

water to the dehydrated floodplain. again, we look at the map, the channel should go like this, and this is only part.

device: this device is called a wave product, what is it currently simulating? it simulates the calculated waves for such, then, a structure, like the coal terminal port elga, and then the waves go there, right? yes, they go there to the far side of our wave basin, where the wave absorber is located. these are these sensors - what is this? these are sensors that allow us to determine the characteristics of waves, they measure the dynamics of free water surface marks, from such and such.

the design of the nizhnezei station has begun, pre-design work is underway on the selemzhinskaya station, this is a station on the tributaries of the amur river, they are very important from the point of view of flood control, and these stations are also very important from the point of view of energy, well, there has been a 5% increase in energy consumption in the far east in the last few years,

so they could be the solution, yes, yes, yes, and here it is up to the country to decide, and which one exactly... we will talk about it, but if it is possible to solve the flood problems, then it should be a hydroelectric power station, this is a complex effect, yes, our current expedition, which we have in the far east, has already mobilized and left to carry out field engineering surveys, to the process, everything, in the process we are in the process, the work is in full swing, energy production is already in full swing at those far eastern power plants, which nevertheless operate on coal, if in simple terms, this... filter, no, this is not a filter, this is a dry radiator cooling tower, that is, a cooler, it cools the circulating water, a cooler, i understand, how many fans are there here.

yes, burning coal, this station still releases co2 into the atmosphere, but everything can be solved, for example, with the economical use of water, they decided here, so here the water accumulated and

went through the filter, yes, that's right, here, this, this filled this reservoir, yes, in general, you are immediately coal miners, and energy and water use, yes, that's right, we we have minimal water losses, but what about co2 interception, this should be the next step for our energy sector, it is mandatory, therefore... we are developing new technologies for the absorption of co2, this is also in the program of our national project new nuclear energy technologies, but this does not mean abandoning coal and gas stations, in no case, i will ask you a difficult question now, today we discussed how new drones will help further development of the oil and gas industry, now we told how new electric hydrogen belazs will contribute to the further development of... the coal industry, and this does not contradict your concept that sakhalin is an experimental site where carbon must disappear, look, reducing

energy costs is the main way to reduce co2, that is, this is the path to efficiency, on the one hand we are talking about ecology, and we are talking about the climate, we are talking about reducing co2 emissions, but in reality we are talking about increasing efficiency, from each process you need... into the tank, that's how it works from reporter's report: electric train drivers have a choice, if we want to save time, we use express charging for an hour and a half and the battery is full, if on the contrary

we save money, then we use this cable, though then we have to wait longer, 6-8 hours, it all started 4 years ago, today there is already a whole network of electric filling stations on sakhalin, and there will be hydrogen ones, although of course, the new energy balance still needs to be built and built, and there is no need to rush, diesel generator. engineer shupnikov taught, we call technology art aimed at increase in labor productivity, but that 's for another film. so, we've been to the shores of several oceans

today, including here on easter island, on the opposite shore of the pacific ocean from us. but now ahead of us is the russian far east, specifically vladislav vostok, and the upcoming eastern economic forum. see you there.

let's return to the news review, we'll start with a report from belgrade, the ukrainian armed forces have released about '. in one day , the ukrainian military has released more than 100,000 rounds of ammunition across the region, including the elderly district. 100 shells. our special correspondent, olga kurlaeva, is on the line. olga, hello, what information do you have at this minute about the situation in the region and the consequences of the attacks. yes, hello, well

, it is not customary to wish us a good day here, but at about 3 o'clock in the afternoon the shelling began, the alarm went off, the danger signal, the missile danger, many managed to run for cover, here in the belgorod region this is customary, there are no careless people here, they really know what a missile danger is and how they can fragments can harm a person's life, in general , deprive him of it. we are now at one of the addresses where the ukrainian shells arrived , the operator will show this now, this is august 5, august 5 street, a high -rise building, the glazing is damaged, territorial defense is on duty here, there is a car nearby, you can see for yourself how much the fragments are scattered, cars are damaged, trees are cut down, the glazing of the entire house is damaged.
