the water. especially at the equator. on the other side as the earth is literally pulled away from the ocean from the moon. we get the strongest tides and if you're in the right place at the right time the moon even provides enough energy to. incoming water. turtle nature of the power. and the idea of using the tides for humans purposes has been around for ages several hundred years ago enterprising engineers constructed flour mills powered by the daily. people have looked to harness the tide for electricity generation in the twentieth century a number of projects around the globe were proposed but were decried as economic madness for a time it looked as if the proponents of title power were fighting a losing battle but in one nine hundred sixty three the rance river estuary in

brittany france was blocked off to start construction on what would be the first industrial sized power station in the world in the process of one and a half million cubic meters of water were displaced for seventy five construction site. twenty four turbines have a capacity of two hundred forty megawatts to this very day but the hefty price tag dampen enthusiasm for such plants in the country but that didn't deter others who knew to be done better and more cheaply. today and. around the world where it's possible to construct a good plant for sure we're good. but .

i think it's safe to say that there was one man that was the driving force behind the. idea. or. the concept even before. when he was. he had already played the idea of a power station. this means while working. he travelled. home which is remarkable for.

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. . for innovative engineering projects like baby. because of the many. fluctuations in the water level as the tide rushes are more pronounced than otherwise would be the views can be breathtaking. having stripped away the top layer sediment leaving mostly exposed. water. purposes the most ideal spot for the world's second title power plant was here. because it's. connected directly to the via an especially. compared with a concurrent competing project in france. much less invasive site prep was required. there was absolutely. nothing people thought

were going about it. there was no way you can build a tidal power plant like you can. perhaps the most important breakthrough was a revolutionary method of construction. powerhouse. greatly reduced environmental damage in france. the climate proved to be another potential obstacle. to find a concrete composition that would survive such severe winters. and we managed to make create.

invented develops. that is the core of the entire facility. so once the construction was complete they simply attached a giant pontoon filled the dock with water and 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 measure just a hair under one hundred kilometers. an hour triumph. before everything went well it took us one day to transport planes. under water. this was a great success. we get universal recognition. in the decades since those

accomplishments have withstood the test of time. it 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 powerhouse operated its entire useful life without problems or substance of repair and 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 in the arctic frigid waters. at the center of this russian engineering feat a french 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. reverse thanks to the special made blade system however most of agree that it's often better to just use in one direction because water rushes back out to sea it operates at ninety percent efficiency but only fifty

percent in the other direction. some friends it was a seven. but also very complex and expensive one of the units was equipped with a french turban 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 here it is an orthogonal turban. based on what's called a 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 spins 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 of 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 well 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

activity here surprisingly simple an actual operation. power plant can be. no 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. turbine. to create electricity. construction. itself.

past you. produced 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. the fact that it has to be floated out to. particular challenges for design engineers. in the region of fifty to sixty tons these generators are far more likely to sink than swim when face to face with water. engineers decided.

to try. but we. were also developed tested. in japan because. they were able to achieve. thirty percent. so they gave up working on such projects and with you know with both and we picked it up we changed the blade. as well as the section to. today our turbans efficiency factor is as high as eighty two percent. that is. thirty eight percent to eighty two. if you want as a result our design is more energy efficient than the french turban which was

brighton. song from phones to impressions. means queenstown totty dot com. it took years if not decades to get that turbine just right but now with that in hand institute of energy structures is ready for the next challenge to the next

logical stages to achieve. these measures in megawatts where is will need to. downsize you have a totally different scale and require a different approach. the remainder is deeply so with the plant with three year olds to a bind the generators capacities for megawatts the roller is five meters in diameter and the bleats. bruce hydro plans to test out the new design in the waters of the on the barents sea the severn 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 in individual sluices which will give it a total capacity of twelve megawatts however given that the power house is only

a small part of the entire piece struction engineers have found a way to boost energy generation by using the previously into. increased threefold. the thing is that we have. these so-called. exact same terms. except they're driven by. crashes into. the rising forces inside the. electricity. heat. and the turbine in creating tricity. together to create more powerful.

perhaps most interesting. power plants. place previously simple concrete retaining walls. at the institute and. this is the. fan that generates an airstream pressure of. the air rushes through a pressure air duct and into the. this is exactly the kind of turbine there will be installed on the new. power plant which scientific research institute of energy structure just finished developing. terminus connected to a generator. including pressure. readings enable us to evaluate 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 the. conditions different. because. 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 converters out there but these engineers are confident that they're designed for something other simply can't. 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 . first we came up with a concept of an orthogonal turbine 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. a huge amount of electricity. since the tide only comes in and out twice a day all of its potential energy has to be harnessed in short bursts to help sort out 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 the water back into the upper reservoir more often than. peaks in electricity demand in the morning and evening. 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 in 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. it did reach design to capacity in two thousand but is currently operates at full power. this practice to storage power stations are normally placed in mountainous areas with 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 pump 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 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 loose hydro is pushing ahead with the second phase where the client is located is seven hundred fifty meters south of the existing facility design work started in two thousand. in the first. two thousand and eight it's one of the biggest construction projects in russia at the moment with 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. 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 it will be able to burst through the pipes every second similar foreign facilities have chosen to use. a water pipe made of metal is prone to such. when we were designing our. be considered employing such metal. 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 plans 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 of spare capacity in order to get the added. quickly as possible the structure of the messenger later made parts is taking place around the clock with five thousand people employed in three shifts the generators will boost existing capacity by eight hundred forty megawatts one will reach that powerhouse by traveling eight hundred pipes the new. cubic meter pool is being built right next to the existing. of the. lower reservoir rather than build an entirely new one will be the fourth largest pumped storage plant in the world achieved it's obvious that if russia should make use of its immense potential for tidal power generation and

put it into practice then pump storage power plants would definitely come in handy particularly to compensate for tidal plants not ural cyclical pottery like we. know together or separately these technologies are under likely to sate all of society's 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 the some of the greenest methods of power generation out there and 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 chef occasion but that'll do it for this edition of technology update will see you next time and until then enjoy the ride.
