I graduated from Mechanical Engineering in 2002 from the University of Toronto specializing in aerospace and environmental engineering and we knew then that they would be an expensive, high maintenance, high break rate machine that also had significant negative environmental effects. At such massive scale, each unit requires as much maintenance as an airplane. This was common sense 20+ years ago.

Very much new to all of this, but curious to learn more about the feasibility of installing wind turbines (smaller scale) on an plot of land in these islands, and thought you might be able to shed some light on this. Anyways, hope you see this! Cheers!

Actually much of the maintenance is automated and observed by human hands. Wind tubines give long trouble free service. Blades need to be changed and the gear oil needs changing but both the blades and oil are recycled. Blades removed are checked for cracks then resurfaced ready to be put back on for another cycle. Its not rocket science.

They all have MASSIVE gearbox to get the revs up for generator to work. I haven't checked, but at least three stages, meaning three pairs of gears, each pair turning a couple of percent of torque into the HEAT. A couple of percent from 3MW turbine, means approx. 100KW or enough heat for about three houses in winter. Amount of oil? Just about 100 gals of oil or more. What can go wrong??? NOT a detailed analysis, but a ballpark one. We all MUST stop this sheet madness, before the idiots destroy the industry and send us all back to dark ages.

I asked him if he had a big enough vehicle for the 4 foot by 8 foot sheet of plywood. He replied rudely that he was an engineer and he knew what he was doing. When we arrived to his compact car i laughed and asked him how he would fit inside his tiny car. He ended up returning the sheet of plywood because he didn't want to rent a truck or cut the wood down to fit.

I have been developing monitoring systems for wind turbines for ~15 years. The wear is (of course) real, but nobody expected maintenance free! That being said, the maintenance is more than expected, especially offshore (and other hostile environments like deserts and Sub-Zero tundra). Reasonable estimates would be between 1.1 and 2.5x expectations. Only a small portion of that comes from blade edge wear. I have never met an engineer that thought "small things can't wear out big machines". Wear/load is integrated over the life time of the turbine. I continue to be amazed with how good the engineering on most of the turbines is. These machines are facing load of megawatt, continuously, in some of the harshest conditions any machine are placed in. It is amazing they require as little service as they do.

Dupont (now renamed) has been selling the stuff for years and is amazing for industrial spec application but once you create the final product it is then very difficult to recycle or destroy. The kapton tape stuff technically doesn't even burn.

Funny you should mention burning ! I created a wood burning stove that burned so hot that I was going through grates made of 1/4" thick stainless steel about once every 10 hours of burning. I started putting cans of old nails and screws on the grill to protect my SS grills - the design was based on the "Turbo Jet Engine" principal which is seldom stated or taught which is "Reintroduce a large portion of your output energy to drive the input" This principal can be used in many other areas like SAVING MONEY - You know - Interest or Rent are good examples or a business in which the owner does not spend the money made but just builds a bigger business to put out more money .... It's the basis of FIRE and many other runaway chemical reactions or any runaway reaction. Just take a large percent of the exhaust heat and reintroduce it to the combustion chamber via the Fuel And Air ... done right you can burn almost anything!

Not necessarily. You have to take all the power that wind gives you or none at all. So turbines are disconnected and static if there's no demand for that power. No engineer has ever claimed they'd be maintenance free, and blade erosion was expected and designed for. Yes, in some cases it's more than expected, that's the nature of making predictions. Sales people oversell thing once in a while too. The video is sensationalist attention grabbing with at best a tenuous link to the truth.

You have to consider what the engineering knowledge overlap was. Were aerospace engineers working on these structures or did the infrastructure engineers go at it with and how much cross-discipline information sharing and employing happened while these projects were designed. It's not that unlikely imho that no one on the teams designing these structures had intimate knowledge of leading edge abrasion in airplane props or they had but siginificantly underestimated it.

There is no other solution, because building a low EROI system, or lowering energy consumption, will definitely make most people poor(er).

Where is the issue, blade are removed, checked for major structure integrity, major cracks, then resurfaced and put back on. Large wind farms keep the means to do this and are always in the process of changing blades or repairing them. Much like you change tires on a car or a roof on a house. Everything needs some degree of service. Nuclear reactors, oil or gas fired generators or coal fired generators all need to temporarily shut down for service. Where is the big deal about serviceing wind turbines?

This video presents a warped picture of reality. Blade erosion has always been a known, and very routine factor for wind turbines. Look at the lower part of your car after 250,000 miles - one year for a wind turbine, but the blade is going 3 times as fast. Another factor is the buildup of dead bugs - special airfoils tolerant of the resulting rough surface of dead bugs (think of your windshield if you always drove 150 MPH in a rural area and never washed the windshield) are used. There are many approaches to preventing blade erosion: leading edge tape, special coatings, etc. were all well known in aviation, with off-she-shelf solutions available. They each have their positives and negatives. Different solutions work better in various climates, locations, types of blades, budgets, expected lifespans, etc. There is one system that coats the blades in layers of alternating colors, so you can see if there is erosion at a glance, by the color change. Seems like a hard surface (metal) insert might help but it would be expensive and introduces more problems. The last thing you want is crap hanging off your blades causing the machine to be unbalance,d either by mass or aerodynamically.

@@harleyme3163 I think you seldom see leading-edge erosion on a vertical-axis machine because they would have to remain in operation continuously for a few years for that to happen, which they do not, since they usually break a blade long before then, assuming they are even mounted in a windy location, which they are often not. We had a big, heavy-duty, industrial-scale one down the street - lasted about a year - it gets windy here. Meanwhile the market-leader 10 kW wind turbine here has constant noise issues from loose leading edge tape, and the leading edges of the wooden blades on my 1 kW machines always look like they have termites after a couple or three years. Lots of dust in this here desert. :)

5:40 Some of the larger turbines hit more like 200 MPH at the tips in a medium-to-high wind. I once timed the blades for the Clipper Windpower 2.5 MW unit installed at Kirkwood Community College (Cedar Rapids, Iowa), at just over 17 RPM - on the shortest blade that model of turbine had available, it works out to over 280 km/hr (almost 175 MPH) at the tips of the 88 meter (IIRC) blades - if it had the longest available blades (97 meter IIRC) it was doing about 195 MPH at the tips. It might have LOOKED like the blades weren't spinning all that fast, but do the math....

If only the blade engineers (who, admittedly, possess awesome math and design skills) had talked to people, for example, in the steam turbine industry. They may have learned that gas flow has to be extremely clean or airfoil blades will experience all manner of pitting problems. When I first started working as a mechanical engineer 50+ years ago an old fellow who was my mentor told me that to be successful I needed to ask the operators, mechanics, machine shop personnel, etc, what their opinions were, and to listen carefully. He said they frequently already know the answers to mechanical failures but are unwilling to say anything because too many engineers would ignore them (or worse, tell them to stick to their own business and leave the engineering to the engineers). It was the best advice I ever got.

It kind of is dramatic as the ultimate goal of renewable energy is to be more environmental friendly. The goal is to reduce the carbon dioxide emission and other environmental impacts while providing a constant flow of energy, however a wind turbine power plant on land can take a lot of space, which mean deforestation, they also kill countless birds who accidentaly fly into the blades, however the biggest problem is how much polution is created for building and maintaining the parts of a wind turbine and not being able to sustain a constant energy flow. Also knowing the fact they do not provide as much power as hydro electricity and nuclear power plant which both have low environmental problems, it is a must for the wind turbines to keep replacement parts to a minimum and to generate more power to be an advantageous solution.

Where I live they do not put wind turbines on other's land, as no one wants the insane sound of a large amount of turbine spinning near them, also there is enough unhabitted space to use, however being unhabitted by a human doesn't mean it is not habitted by something else. I do agree that other methods of electric production have their share of problems, but as of the current situation, they are more worth it than wind turbines, which is why I say it is dramatic that they fail so fast as reliability is their selling point.

I'm not sure if this can really be called a "mistake". Modern wind turbines were probably the first ever example of large, high-performance aerofoils being operated for years at a time at such low altitudes (since being close to the ground presumably means a lot more abrasive particles in the air) and at such high airspeeds. When you're doing something new, you'll never be able to predict everything. I'd save the word "mistake" for when engineers failed to predict something they reasonably should have known about in advance.
