Wind Turbine Construction - Harnessing The Wind | Full Documentary

Masterpieces of German engineering: Electricity from wind power provides the second largest share of energy supply in Germany since 2017 - and has thus outstripped nuclear and coal power. Nearly 30,000 onshore and offshore wind turbines are currently in operation in Germany, covering around 19 percent of energy consumption.
This documentary follows the construction of a new wind power plant in Falkenthal in Brandenburg. Once installed, the windmill will be 179 meters high and will supply up to 5,000 households with electricity. But building up a wind turbine is a difficult task.

That's crazy that the towers are all rings of concrete. Here where I live they make and install wind farms in the mountains. The towers are all fiberglass, same as the blades. Installation is SO quick compared to what I'm watching. NOT bashing this though. I LOVE watching things like this and learning how thing's are done or done differently.

[@Kangenpower7]

I have never seen a wind turbine tower made of fiberglass, but most in America are made of steel. This tower has the lower 90 meters (or so) made of concrete, then the upper sections are made of steel. I think that a fiberglass wind turbine tower might crack from the stress of being pulled to the left and right by winds coming from different directions (on different days of the week). While the concrete being pre-stressed, it is not subject to cracking, and the steel is stronger than both in both pulling or pushing stress. Concrete is just a lower cost material, that can be used for the lower 1/2 of the tower. Beyond a certain height, the concrete gets to a point where it's weight might crush the tower support if the concrete went to far up the tower. Also the concrete sections are larger diameter than the steel sections, so will interrupt more airflow than the steel tower. The lower rings, I think they said they are 20 meters across. Some of the wind towers in America have a elevator inside the tower! Just a one person elevator, with a 750 or 1,000 pound capacity, so some tools and equipment can be brought up in the elevator too.

The wind turbine will keep turning as long as there is over about 15 MPH wind speed. Below that speed, it will normally stop. The wind turbines are connected to the grid, and the washing machine to the same grid. The grid has the ability to collect power from any spinning generator, and will not stop any of them when the power demand is to high. Just that the washing machine will get it's power from this spinning wind turbine, or another generator, from someplace!

[@swunt10]

@@MartinInAmsterdam A real engineer should know that as in english, most other languages have conflicting definitions of what these words mean and there is no ultimate semantic definition. the important engineering distinction between screws (with or without nuts) and bolts (with or without threads) is that a screw connects parts using 'frictional connection' by only using it's threads and the screwing motion to create a normal force pushing together the two parts causing enough friction between them to restrict movement. whereas bolts use 'form fit' as connection method where the bolt itself takes all the shear forces and surface/flank pressure just like rivets. Of course there are idiots, including fellow engineers, who think a machine screw with a nut is called a bolt by most people and therefore can be used as a bolt for form fit connections which usually ends in disaster since the sharp edged threads of the screw creates a material weakness and shearing forces easily destroys the screw since a screw is not meant to take shearing forces or surface/flank pressure at all.

[@MasterFeiFongWong]

This may be off topic, but someone might find it interesting.Over unity electric generator. By AMA. Segment 1: 1 motor with bar connected to it standing vertically. Circular disc connected to bar that has magnets embedded in it surrounded in high permeability material to focus magnets outward pushing force in an upwards direction from top of disc. Segment 2: Hollowed out cylindrical Bar of material horizontally positioned. Flat hollowed out ring shaped material with openings around its outer top flat edge. Magnets surrounded in high permeability material embedded in these openings. Magnets positioned in openings around ring are in at least 1 of 2 configurations either all N magnetic field pushing out or N,S,N,S all around it. Just depends on whether your going for Piston structure or spinning structure explained below & whether you want it to be DC or AC current. Place these all along the cylindrical bar connected to it solidly, except at far ends of bar. At both ends of bar place ring of material that can be magnetically repelled in specific locations. (magnetically repelled in specific location is in reference to outside of ring area that faces away from center of bar)(Other side of same ring facing in towards center of bar is capable of being magnetically repelled all around) Ring must be connected solidly to bar. points of repulsion on these rings is off set from each other on each end of bar. 3 Hollow ring structures with small square bars protruding from each. Ring structure has all magnetic repulsion on inside of ring shape & can rap around the main bar so that the bar wont be causing friction on things as it moves back and forth or spins. 1st positioned around far left of bar, 2nd position at center of bar (be sure to leave enough room for magnetic structures to be able to move back and forth without hitting it) & 3rd positioned on far right of bar. Tube structure is constructed in two parts that fit together on top of each other length wise over main structure. Tube structure has 3 square openings for the bars that the Ring structures that are connected around the main bar keeping it from causing friction on structure, to slide into. This tube structure is designed with material that does not block magnetic fields. Perhaps some type of transparent material glass or other. At both ends of the tube structure there is a built in circular groove that will house a round disc. The ceiling/floor/left side/& right side of groove has openings for small magnets to be embedded in it, so that the pushing force from magnets is pushing in towards the edge of disc that goes in this spot. There is also 4 openings located on the top, bottom, left & right positions of the open groove. Small magnets are placed in these spots so when round disc is in position these magnetic fields will hit sideways keeping it from generating friction against structure. Far Ends of bar has Cap structure that screws over tube halves holding them together. Cap structure also has 4 points on inside top, bottom, left & right that have openings. These openings have small embedded magnets in them that exert there pushing force outwards (sideways) so it will keep disc in position, generating no friction against structure. Cap is made of material like tube so it does not block magnetic fields. (Note: These magnets in groove and cap structure are only needed for piston design. If Disc is directly connected to main bar so as it spins the bar spins, magnets are not needed here). The disc has ring around it (ring of material goes around outer edge and folds over front side & backside a small distance) that is repelled by magnetic fields so the 12 small magnets will keep it lined up but it will be able to spin without causing friction on structure. The disc has openings on it's flat side that face inside of tube and magnets surrounded in high permeability material are embedded in this disc. The disc has small bar that is connected to it's center that goes all the way to the other end of bar structure through the center of the hollowed out bar and connects to disc on other end. Disc on other end is set up the same but magnets embedded in it are off set in comparison. As first disc spins the magnetic fields will push against specific spot on disc connected directly to bar, pushing bar in other direction, once bar is fully pushed over, further spinning of disc will then align the other sides magnet to push it back. Tube structure also has half moon shaped protrusion on inside and on both halves so when tube is connected they line up to make a full ring shape on inside of tube, these half moon shaped protrusions have at least 1 small round opening on it's side in middle of curve that faces away from center of bar. The opening has a small magnet embedded in it so magnetic force is repelling out sideways away from center of bar. The protruding ring is positioned to line up slightly further in towards center of bar then the ring of magnetically repelled material connected directly to bar. This way when bar moves right or left it is magnetically stopped after a short distance. Copper coil setup: Copper coils are wound in at least 1 of 2 ways. Either coiled in circles next to each other (Like if you wound coils around a cylindrical bar) or laid out in a row as if wire was on flat table going up then bent to go down & back up until it formed a flat rectangle of wire bending up and down and then the entire structure folded around tube. Copper windings are then lined up perpendicular to magnetic fields on outside of tube. Ends of copper coils are connected into separate construct that will allow electrical current to flow somewhere else. Circular construct is built like a stand that goes around the outside of motor segment. Circular construct has flat ring of high permeability (magnetic field shielding) material that has small openings that will allow magnetic fields through specific locations. Top of circular construct has groove to allow the horizontal bar to balance on. Circular construct can also be placed on other end of bar so it is balanced. The motor segment is positioned so the disc connected to the bar that is connected to the motor is lined up so the disc passes under the horizontal bars disc that is at end of horizontal bar. The high permeability material keeps the magnetic fields in disc from hitting into the disc that spins or pushes the horizontal bar until just the right moment when the impact will cause the disc in horizontal bar to spin which will perpetuate the piston motion in the horizontal bar. More horizontal bars of the same design are built and positioned around the motor segment in a circular horizontal fashion all the way around. The bar connected to the motor can be increased in length to desired height (As much as motor can handle) and more of the exact same setup is repeated higher and higher up, maximizing the over unity potential of the construct to ridiculous proportions. :D Current from the horizontal bars is diverted to power the motor as needed and all other current is diverted to power my game console or the world. :) Interesting variation to this design would be to connect the spinning discs on far ends of horizontal bar to main bar that magnets are connected to so the magnets spin instead of getting pistoned back and forth. So long as moving magnetic fields are perpendicular to copper wires it should work. By AMA

[@Kangenpower7]

They do maintenance on these wind turbines, and yes even replace the blades if they detect a problem with them. They have instruments inside the blades that can look for and detect stress in the turbine blades. At about 15 - 25 years old, we find that the 150 KW - 750 KW wind turbines (installed about 15 - 25 years ago) are ready for replacement, as the maintenance costs per MW is considerably more than a modern 2.5 MW wind turbine. And the older 750 KW systems did not have a elevator to the top of the 75 meter tall towers. The Zond wind turbines cost about $750,000 when they where new in 1995, so pretty low cost back then. Now they need to be replaced, and by up rating the wind turbines, it is really easy to get local approval, as they are just replacing a wind farm with 85 turbines with another wind farm with 50 - 65 wind turbines, but at a much higher output per turbine. If you watched a video of the wind turbine blade testing, it is evident that repairs would lead to the question "Will it hold up? For sure, 100% all better now?" And thus the bean counters and lawyers get involved and say, better and safer to replace it than to make the excuse "We thought the repair would be strong enough" and it worked for a few weeks / months before it broke and killed that poor guy driving by on a motorcycle.

100 of the best turbines equals to just one nuclear reactor, I think nuclear power is better you can have 4 or 5 1000MW reactors working 24/7

[@Kangenpower7]

The problem with a nuclear reactor is nobody really wants one in their back yard. Also I have never heard of a nuclear reactor coming in under budget or on the scheduled date to start operation. The problem with that is the $5 Billion they already spent needs to be paid back as soon as possible, and when you delay that start date by a couple of weeks, the payback time is extended, and there is nothing to pay the loan payments for that additional 2 weeks when the station is late at start up. And most nuclear power plants sit for a couple of years before they actually start running to produce power. So that $7 Billion borrowed to build the plant is needing to pay $700 Million a year in construction loan costs. And that is a substantial additional cost added to the budget to start the nuclear power plant. While a wind turbine power plant, you can start the turbines within a week of finishing each turbine, and start generating power even before the 15th wind turbine has been installed! So payback sometimes starts even before the project has paid for all of the wind turbines, and borrowed all of the money they will need to complete the project! And many are finished within a few weeks of the construction schedule, and within a couple million of the cost estimate. Natural gas power plants still come in at a few weeks to a few months over the scheduled timetable, while most come in at a few million over the budget, and perhaps run into a problem, like the 36" pipeline going to the plant might cost $35 million more than they estimated, or some other problem that happens. And remember that $250 Million dollar natural gas power plant needs to pay around $25 million a year in interest on the loans they take out for construction, or about $1 Million for every 2 weeks they are late. !

There are many wind turbines over 25 years old that still run fine. That is well over 50,000 hours of run time, and about time to replace anything with that many hours on it. Like driving your car for some 2,500,000 miles. Ready to replace it? Most of the Zond wind turbines are rated at 750,000 watts and cost about $750,000 to install back in the 90's. At 25 years old they deserve to be retired. And the cost to maintain a 25 year old turbine is a lot more expensive than a new 2.5 MW model, the new ones even have a small elevator to take the maintenance to the top! And the percentage of run time is higher with the modern wind turbines that are taller, with much longer blades. So they can run at 12 MPH, instead of the 16 MPH cut in speed of the Zond units.

[@Alex-ly4go]

So, from what I've been learning so far about wind turbines is that they are (GENERALLY) tall enough to get atleast some sort of breeze that helps move the blades. Also there are different types of wind turbines! So ones that are on water (offshore) are able to get more wind because of their location. Same with turbines placed on planes (as seen in the video). They are able to get more wind because there aren't many barriers preventing wind from getting to them. Also, some wind turbines may have batteries to store energy in when there isn't much being produced! So any excess energy that isn't being sent to the places they are providing energy for, is being stored in the battery for moments of "inactivity," if you will? Once again, I'm not 100% positive if all turbines have batteries, because some are connected directly to the power grid, but a fair amount do just because if convenience! Solar panels have the same option to have batteries in case there are cloudy periods of time or snow.
