more news today violence is once again fled uplifting these are the images the world has been seeing from the streets of canada. giant corporations are old today . hello and welcome to technology update with demand so wearing and resources limited the sun could be setting on an outdated era of global energy simply put new alternatives to invoke alternative sources or the best bet going forward energy directly from the sun is often the first thing that comes to mind when people

mention solar power however when you really think about it the sun's responsible for far more than just fuelling solar panels wind farms are an indirect result of the sun's rays as convection currents drive global air streams and create the majority of gusts on the globe. and in fact there'd be no plants or trees to make biofuels from if there was no sun to spur on photosynthesis in the first place. as those plants die off and decompose thermal heat and pressure slowly turns those into fossil fuels like coal and oil however there is one source of energy that has no apparent connection to the sun instead the moon is to think for the motion of the ocean that we know as the tides is relative proximity it exerts a much stronger influence than the sun. as the moon circles the globe the water closest to it gets pulled out words especially at the equator there's also a smaller bulge on the other side as the solid earth is literally pulled away from the oceans furthest from the moon when the sun moon and earth are aligned we get

the strongest tides and if you're in the right place at the right time the moon even provides enough energy to surf on its title bores funnel incoming water down narrow river ways. in this rights reflect the eternal nature of the moon's tidal power. and the idea of using the tides for humans purposes has been around for ages several hundred years ago enterprising engineers can. 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 hundred sixty three. blocked off to start construction on what would be the first industrial power station in the world in the process of a half million cubic meters of water were displaced seventy five construction site

. twenty four term passive two hundred forty megawatts to this very day but the hefty price tag dampened enthusiasm for such plants in the country but that didn't deter others who knew it could be done better and more cheaply. today. but. i think it's safe to say. that was the driving force behind the.

idea. even before. thirty eight when he was. he had already played the idea of a power station. where to build one instance while working. he travelled. home which is remarkable. 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. 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. water. purposes the most ideal spot for the world title power plant was here. because it's. connected directly to the via an especially outlet compared with a concurrent competing project in france. much less invasive site prep was required. there was absolutely nothing 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. entire power house. greatly

reduced environmental damage like that scene in france. 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. they invented develops. that is the core of the entire

facility. so once the construction was complete they simply attaching joint pontoon filled the dock with water and tugs the 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 the planes. to the underwater. this was a great success and once we had done it we get universal recognition. in the decade since those accomplishments have withstood the test of time. floating method has become an industry staple project engineers everywhere cut costs by as much as up to fifty percent and the station itself is 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 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 as well as in 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. some friends it was. good 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 it. and so we did here 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 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 lush one of russia's leadership in submarine makers and a testament to the relative simplicity of the new rotor system the whole complex

complete with turbine and 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 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. in just a few workers. and

. 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. turbine. to create electricity. construction. the past you.

produced so too was the generator. here. on a tried and true fact to construct probably the second most important part of the station. factory is one of the country's top makers and generators. including those special. tricity plants and then all of that experience prepping for the tidal power plant. particular challenges. in the region of fifty to sixty tons these generators are far more likely to. face to face with water. energy from the vertical shaft to a horizontal one but one of the arrangement. the generator is only as useful as

a turbine below the powers that. turbans were also developed in tested in canada in japan. they were able to achieve an efficiency factor of thirty percent. so they gave up working on such projects with both and we picked it up we changed the blades as well as the section to. our turbans efficiency factor is as high as any two percent. increase that thirty eight percent to eighty two. as a result our design is more energy efficient than the french turban which was considered the classical type. of this.

nuclear. side. radioactive fallout of government betrayal. and laud how can the truth be revealed if there's no official evidence there was a very bright day to the servicemen concerned who will give protection and to the people of this country generally because all right deal like the full. the secrets of the u.k.'s nuclear tests.

more news today is once again flared up. these are the images. from. china corporations are today.

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 the next logical step. out. of a totally different scale and require a different approach. with three. generators capacities for megawatts the rollers for. and the bleed. design in the waters of the on the barents sea. 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 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 construction engineers have found a way to boost energy generation by using the previously concrete blocks. by using wave. title pole plan project plan can be increased three fold if you. are so much more efficient the thing is that we have a lot of space which till now been used for power generation. these so-called oscillating water columns use the exact same turbine as the tidal power plants except they're driven by air rather than water. crashes into the. the rising forces inside the. electricity.

heat. and the turbine creating tricity. together to create more powerful. perhaps most interesting. blocks of place previously simple concrete retaining walls. at the institute and. this is the. air driven. 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. term minus connected.

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. under various conditions different speeds or alternating flows one thing they've noted is that because the turbine spins in the same direction regardless 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 are designed for

something other simply. some power plants that are shaped 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 that absorb. 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 plant. 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 tidal electricity. ok proceeding.

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 the 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 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. 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 is seventy four percent of you couldn't hear it as 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 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. storage are being constructed at the company's metal factory which has been in operation for over one hundred fifty years 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 this. is located

seven hundred fifty meters south of the existing facility design work started in two thousand and seven. and the first cement 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 really. 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 and is prone to so.

when we were designing our power station it would not 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 cheapest in comparison to those made out of metal it is one hundred percent. according to roos hydrous 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 or maybe parts 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 travelling eight hundred meters pipes the new roughly

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 will be the fourth largest pump storage place in the world achieve 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 not ural cyclical pottery. no together or separately these technologies are unlikely to save 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 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
