people have looked to harness the tide for electricity generation. a number of projects around the proposed. economic. time it looks as if the proponents of title power. but sixty three. blocked off to start construction on what would be the first industrial power station in the world in the process. meters of water were displaced seventy five construction site. twenty four term passive two hundred forty megawatts. but the hefty price tag dampen enthusiasm for such plants in the country but that didn't deter others who could be done better and more cheaply. today.

but. i think it's safe to say. that was the driving force behind the. idea. or. the concept even before. thirty eight when he was. he had already contemplated the idea of

a power station. and this means while working. he travelled. home which is remarkable for us. despite the fact that it's up in the arctic circle more months it was already a well established and thriving port in the one nine hundred sixty s. . the industrial might for innovative engineering projects like baby. because of the many narrow. fluctuations in the water level as the tide rushes are more pronounced than otherwise would be the views can be breathtaking when the last ice age having stripped away the top layer sediment leaving mostly exposed rocks jetting out of the water. purposes the most ideal spot for the world's second title power plant was here. because it's. connected directly to the

sea via an especially narrow outlet compared with a concurrent competing project in france. much less invasive site prep was required. there was absolutely nothing like it nothing at all people thought were going about it. there was no way you can build a tidal power plant like you can and. perhaps the most important breakthrough was a revolutionary method of construction instead of blocking off the waterway. powerhouse. greatly reduced environmental damage like that scene in france. arctic the climate proved to be another potential obstacle. we had to find a concrete composition that would survive such severe winters. and we managed to make create.

that we had invented we developed. that is the core of the entire facility. so once the construction was complete they simply attached a joint pontoon filled the dock with water and tugs a whole complex to the chosen site along the way they took the opportunity to monitor how the structure fared in rough seas in total the trip from more months to measured just a hair under one hundred kilometers. an hour triumph.

before everything went well they took us one day to transport the planes. to the underwater foundation this was a great success. we get universal recognition. in the decades since those accomplishments have withstood the test of time and. floating method has become an industry staple project engineers everywhere cut costs by as much as up to fifty percent and the station itself has also held father time the original power house operated its entire useful life without problems or substantive repair and when engineers tested the state of the two thousand they found that the walls of the structure were in great shape even after nearly forty years of constant freezing and thawing of the arctic frigid waters. at the center of this russian engineering feat a french hard turbine with rotatable propellers was the most complex and most expensive

part of the power plant it could generate electricity as the tide came in with water rushing into the blocked off a reverse thanks to the special made blade system however most of agree that it's often better to just use in one direction because as water rushes back out to sea it operates at ninety percent efficiency but only fifty percent in the other direction. we bought. from france it was a. good but also very complex and expensive one of the units was equipped with a french german and the other one was left empty forty five years ago we had hoped that we would eventually make a turban. and so we did it is an orthogonal turban. based on what's called a dairy is turbine and uses blade shape similar to airplane we. can vary in depends

on the speed of the water goes of which way the water flows in the turbine strains in the same direction with no significant change in efficiency and after being tested out for a few years and eventually found its way into a brand new title power plant that was being added onto the existing structure. to produce a new turbine and powerhouse hydro turned to one of russia's leadership in submarine makers and a testament to the relative simplicity of the new voter system the whole complex complete with turbine generators was constructed in around six months as a factory just outside of the white city about hunger and in two thousand and six following as much fanfare that would normally accompany the launch of a new ocean liner the floating power plant made its maiden as final voyage to keep . just like the original it was towed on

pontoons into the bay instead of tearing down the existing structure they left it in place and simply attached. to the face of it which by the way had been made a monument to russian science and technology. outfitted with new digital equipment the original control room still remains the hub of human activities here surprisingly simple an actual operation. power plant can be. more than just a few workers. need. any machine. which can be mounted. in the process of converting. tricity is rather straightforward as well get the turbine

spinning it operates pretty much like all other power generation plants out there because of the. vertical shaft. of the turbine. to create electricity. construction. itself. past one and a half. and that's not. so too was the generator. here. on a tried and true fact sure to construct probably the second most important part of the whole station. electro machine building factory is one of the country's top makers and generators. including those special built for small and medium sized

hydro electricity plants and then all of that experience prepping for the tidal power plant. has to be floated out to. particular challenges. in the region of fifty to sixty tons these generators are far more likely to. face to face with water. engineers decided. they were able to achieve. thirty percent. you know they gave up working on such projects and with you know with both and we picked it up we mean we changed the blades as well as the section to. end today. the

factory is as high as eighty two percent going to go with that is that some thirty eight percent to eighty two. he owns as a result of our design is more energy efficient than the french turban which was considered the classical type instance of this. good lover touring. was able to build a clueless most sophisticated robot which. doesn't sound anything tim's mission to teach creation why it should care about humans in the world this is why you should care only dot com.

all tito is colm. alex. cohen. oh and. over a decade of north coast terrorist attack. x. hostages blood listen to their lives and after the tragedy. still gives try to cross out the past. because their future will yet be written.

it took years if not decades to get that turbine just right but now with that in

hand hydros institute of energy structures is ready for the next challenge because the next logical stage is to achieve. these measures in megawatts where is will need to. have a totally different scale and require a different approach. to the plant with three. generators capacities for megawatts the roller is five meters in diameter and the blades. to test out the new design in the waters of the box on the barents sea dissever ny or northern tidal power station requires a roughly two kilometer long dam to create an enclosed basin measuring five point seven square kilometers the power house itself will be equipped with a trio of new triple decker turbines that will mean. give it

a total capacity of twelve however given that the power. structure. by using the. project. three fold. crashes into. the rising forces air inside the. electricity. heat. and the turbine in creating tricity. together to create more powerful.

perhaps most interesting. place previously simple concrete retaining walls. this is the. fan that generates an airstream. the air rushes through a pressure air duct and into the. this is exactly the kind of. power plant which scientific research institute of energy structure just finished developing. the term minus connected. there are sensors installed here including pressure sensors angular rate sensors and turbine air speed sensors. their readings enable us to evaluate

a turbine's performance. we have an analysis center that collects all these data and studies them to find patterns and correlations. here's where the incoming data get analyzed. even the temperature of various parts of the construction. they can monitor. under various conditions like different speeds or alternating flow. is that because the turbine in the same direction of the flow it's ideal for use in the water columns in which the direction of. of course there are other kinds of wave energy converters out there but these engineers are confident that they're designed for something others simply can't use to some power plant like a snake but that's naik often gets carried away by the current. the installation is too heavy complex and difficult to secure with all the joints that serve to

generate electricity. there are also hydraulic turbines. but their design is way too intricate and leaves something to be desired. there are floating power stations but they also get carried away if there's. a large humanity's. first we came up with a concept. and then we successfully applied it in designing a way for our planet. and the ground work for including such wave columns in future projects has already gotten started this past year alone hydro built a prototype up and. it will produce electricity for the local grid as well as give the engineers back at the institute precious data to improve the next generation of ocean energy snatchers. could help.

dealing with an inevitable. ok proceeding. somewhat ironically even if. it was. since the tide only comes in and out twice a day all of its potential energy has to be harnessed in short bursts without this

and other peaks there's another type of hydro plant out there this one requires an artificial lake but relies on the natural power of gravity. energy right. hundred meters of. electricity generated. take advantage of lower prices and pump water back into the upper reservoir more often than not. demand in the morning and. they can also be used in tandem with plants balanced approach to energy. pumped storage power. turbines each with a capacity of two hundred megawatts of generation mode and two hundred twenty

megawatts and pumping about it was designed to regulate the energy balance in moscow region and neighboring areas in central russia the power plant was built back in the one nine hundred eighty s. in the one nine hundred ninety s. into reach designed capacity in two thousand but is currently operates at full power. this practice to storage power stations are normally placed in a mountainous areas with a greater water pressure european part of russia doesn't have the kind of terrain however still managed to set up a fairly efficient facility in spite of an average incline of around one hundred. stations efficiency factor is seventy four percent of all of you quit and here at the station is russian made including its turbines manufactured by power machines and its engine generator is produced by the general electric heavy engineering plant that's also part of the individual capacity of each turbine two hundred megawatts is quite powerful a few pumped storage power plants in the world can boast that.

as you just heard the workhorse of the whole plant is made by a company called power machines located in st petersburg they specialize in big powerful equipment like this giant ship propeller. pump storage are being constructed at the company's metal factory which has been in operation for over one hundred fifty years over the decades around twenty seven hundred turbines with a total combined capacity of over three hundred gigawatts. the factories making four by directional turbines each of which can crank out two hundred ten megawatts those new turbines are needed because at present in moscow region there's a pressing need for new capacity. as a result lose hydro is pushing ahead with the second phase here that. it's ok to seven hundred fifty meters south of the existing facility design work started in two thousand and seven. and the first summit was poured in mid two thousand and eight as one of the biggest construction projects in russia at the moment something

like sixty million cubic meters of earth to be moved it's approaching the suez canal like proportions the new expansion comes with a price tag of just over two billion dollars. this gives us a perfect overview of the current state of the construction site. there we can see how far along. in terms of completion. the water ducts measure seven and a half meters in diameter are made out of twenty individual sections three bars welded together before they're hold over to the main construction site where concrete is eventually for in the end two hundred thirty six cubic metres of water will be able to burst through the pipes every second similar foreign facilities have chosen to use. the time to pipe made of metal is prone to such. when we were designing our power station to be considered employing such metal and even an underground conduit but in the end. economic and safety factors we decided

to may not be the comparison to. one hundred percent. according to roos hydras plants the first two turbines will be in place by the end of two thousand and twelve while the third is slated for next year and the fourth in two thousand and fourteen and that really can't come soon enough with analysts saying that moscow region alone could use an additional one and a half gigawatts of spare capacity in fact in order to get the added waters are quickly as possible the structure of the messenger later the main part is taking place around the clock with five thousand people employed in three shifts the four new generators will boost existing capacity by eight hundred forty megawatts one will reach that powerhouse by traveling eight hundred new heights the new twelve million cubic meter pool is being built right next to the existing. one end of the . lower reservoir rather than build an entirely new one the fourth largest pump

storage plant in the world it's obvious that if russia should make use of its immense potential for tidal power generation and put it into practice then pumped storage power plants would definitely come in handy particularly to compensate for tidal plants natural cyclical pattern there is. no together or separately these technologies are unlikely to say. needs for electricity but they could soon play a growing role in completing the overall energy picture especially by adding stability to sometimes unreliable sources like solar and wind but most important of all some of the greenest methods of power generation out there interestingly enough perhaps the only ones that don't depend on the sun in one way or the other only time will tell if there ever become more than just a nice application. for this edition of technology we'll see you next time and until then enjoy the ride.
