  • 4:13 Another reason they make them larger is because wind velocity increases considerably with increasing attitude, and you can see in the equation for power, velocity is cubed.

  • Governments have no business forcing utility companies to use wind power when life span, maintenance, noise issues, manufacturing pollution, damaging the local environment, and high energy costs are resolved. Most of those issues will be resolved, but are far from it. Development should continue, but only privately funded.

  • I would have loved to see an estimation of how big a wind turbine theoretically could get, if we used the best materials/composites possible that exist today. You mentioned carbon fiber plastics being too expensive to manufacture at that scale, and that is definitely true. But let's say that material sciences advance within the next 20 years, and it suddenly becomes economically feasible.. What would be the maximum wingspan using the best of the best materials? Good video nonetheless

  • When the blades are fatigued and due for replacement how can they be best re-assigned into something that would be widely useful. Could the blades be manufactured to be less than optimal so as to be easy to use in some other role? It really goes against the grain to visualise the system just putting these blades into landfill...

  • Hi all @ This is a slight deviation from your exact thread but is still EV and Green energy-related. I was wondering why no one is talking about TE$LA and Wind turbines. With Elon and his company's engineering expertise, I am sure they could design and build The most efficient turbines and towers on the planet. With their knowledge of motors ( and that is all a generator is, a motor being pushed rather than driving a shaft ) coupled with the aerodynamic design of the blades ( remember they have some of the best drag coefficient numbers of any other road car due to their in house designers and fluid dynamics engineers ) That along with Elon’s Materials expertise used to design the towers, and his ability to scale up production at lightning speed, I can’t see how this would not go a far distance to accelerate his change to renewables and away from fossil fuels in the prime directive. Can you honestly think of a better company for this job than TE$LA ???? Eddie in Scotland

  • Have you considered a point of principle at the heart of engineering which apposes compressive structures with tensile structures? How many spinnakers applied in an ocean current could you get for the cost of just the blades of a wind-turbine, how much greater constancy of yield, what greater force from the density of the medium which has a ratio to concrete of 1 : 2.4? With tension the atomic bond of the molecules is doing most of the constructive work. And in the marine - off-shore - the salt is ready-provided for electrolysis. No damage to marine life as opposed to serious damage by wind turbines to avian life, visual degradation of the landscape, fractional interface with the weather system confronted, partial use ability of the same, and fairly huge maintenance and repair costs. They simply cannot be the real future of energy generation. The leap upwards is into Geodetic considerations which means taking a whole view of Ambient Planetary Energy and interfacing with it at large or condensing it for use in more manageable proportions. I suggest that earth-tangent modular isocratic construction is the thing to consider - not minute stalks with blades on them - and that three starters for combination on that route are 1) Geodetic structures 2) the Isotropic Vector Matrix and 3) Khatmatrix - the last little known but essentially ‘normal’ cubic structuring but upon the basis of a syncopated cubeoctahedron and allowing dry-bond construction in the marine.

  • People fail to realize that the big boy wind turbines have a production life of 25 years max then they are rust buckets that have to be demolished because it's too dangerous to disassemble them. The massive composite blades have no half life -they are mammoth fiberglass hulks that fill ENTIRE landfills FOREVER as they do not degrade. There is no such thing as recycling the blades as they are falling apart pieces of junk by the end of their service life. (By the the way, a nuclear plant service life is 50 to 75 years) And we haven't talked about the displaced animals and hundreds of thousands of birds of prey killed every year by wind turbines. If people want green energy then they should back zero emission, safe nuclear that output hundreds of times MORE power (one reactor = 1,520 big wind turbines) on a footprint that is a 100 times less. Remember, this gleaming white monstrosities become massive, broken dangerous rust buckets in 25 year or less -search Germany and wind turbines. The Germans invested first and very heavily in wind and now they are secretly firing up more and more coal fired plants as their turbine are literally falling out of the sky as massive pieces of junk. Research what these turbines and blades look like after 10 or twenty years of service -they are no longer gleaming white statues but rusty and dangerous hulks that literally pose a danger to anything beneath them. The reason they are building these inefficient mammoths is NOT because they are great value for the energy dollar BECAUSE they are built with government subsidies. People and governments erroneously think these initially gleaming white things will last forever -THEY DON'T. The demolishing of these monsters will offset any fraction of use that they had. If they lasted one hundred or two hundred years and didn't wipe out millions of birds all over the world then they might be viable, but they don't. Smaller wind turbines are useful for small remote sites or villages NOT for producing base electricity for the grid.

  • So many false statements in this video I don't know where to begin. The first two minutes are just laughable. Although there is some good information here, it's being presented under a somewhat false or misleading narrative. Engineers have not figured out how to efficiently implement wind into the grid. There are some exceptions of course, as highlighted, but there some major obstacles that engineers have not been able to overcome. The problem is being able to ramp up the power output as needed and store enough extra energy for peak needs when excess is available. We don't have the battery capacity to do so. This is the big problem pro green energy, climate alarmists choose to ignore. The statistics of the effectiveness of wind turbines are inflated numbers. The push for wind and solar is being subsidized by special interest groups and government agendas. As turbines become more efficient, the cost of electricity does not plummet. That's not the way the economics work, especially in a capitalistic society. Not in the real world anyway. The suppliers keep the additional profits created by lowering their costs, it's not passed on to the consumers. The savings are only passed on when a competing product sells cheaper, forcing the supplier to lower their rates. You have to remember, the consumer is not their customer, the stock holders are. Coal plants are not being replaced by wind and solar as the green energy community would like you to believe. What's actually taking place is these plants are being replaced by natural gas and bioenergy plants, aka burning fossil fuels and trees. Everyone should watch the documentary by environmentalist Jeff Gibbs and Michael Moore: planetofthehumans.com/ Although wind and solar have their place, we need to take a harder look at nuclear and hydro options as a more viable solution.

    • @Shamrock what is the largest ingredient in the iron used to make the rotor? Coal. Have yo ever looked at making carbon fiber? You start with a large amount of a special plastic made from oil, then you pull it for a few hundred hours in a huge machine to align the molecules then you put it in an electric oven, pump out all of the atmosphere heat it to 1800 degrees and inject a clorrine atmospher to bur off all of the hydrogen! And you get about one tenth as much carbon fibre . The ore for the rare earth magnets is mined in Africa than shipped on freighters burning bunker C oil to China. there they use huge amounts of water and electricity to refine it. The by product is a radioactive slurry that they dump in a huge lake! Then every ting is shipped all over the world on huge freighter burning Bunker C! Check out some of the ports where they arrive and see how little is on a ship!

    • @Terence Iutzi I have looked it as a matter a fact and it is far cleaner than coal. Where as wind only requires production of parts every three decades coal requires building multiple, large factories, maintaining them, mining coal out of the ground which in of itself requires production of mining equipment and a mine as well as severely scarring the land, transporting the coal, an extremely high carbon emission process and burning it, another extremely damaging process Coal is far worse than wind
