    So what's the big deal? They obviously create these with replaceable blades. As time goes on, we get better and better materials that will last longer and longer. I'm sure they never thought a blade would last forever.

    wind turbines are an eye sore on the landscape, if the were all painted (Green), they would blend into the environment, and not be so noticeable.🌴🌴🌴cuthberteric2017@gmail. com

    What's going on with this stupid research? This problem is solved by a 5 years old!The dust hits the blade, why does it damage the edge? Because it hits HARD! You need to cover the blade with a smoother material, not tougher. Then, the momentum of the dust will be absorbed at impact. Because the wind acts in molecular level the significantly difference scale from molecular to particulate may not affect the generated power!

    Now you have epoxy and glass fiber pieces polluting the air and water, not to mention birds being killed.

    I'm sorry, but I find it suspicious how I have seen the crazy haired women on so many different kinds of scientific shows. Plus, she doesnt get that much airtime either. Stick with a specific field woman, than I can start listening to you more seriously. Oh yeah, dropping the whole talking to us like children thing would be a good start.

    Lol his demonstration is like a 5th grade science experiment🤣😂 this guy knows what he’s talking about🤣

    Uhm simple fix use a 3M film protection layer on the leading edge

    This is so friggen stupid. Just look at the headlights of any modern vehicle. Their plastic, and worn after a couple of years use. Now look at the painted metal next to the plastic headlights. It's not as worn.So make the blades out of painted metal.

    Cant see why they didnt know or expect this would happen. Same thing happens to boats that are made out of the same materials.

    Why don't they use a Aluminum cap on the leading edge? Yea it would add some more weight to the blade but you would think it would be stronger against abrasive forces

    The blades aren't biodegradable. Old blades are shredded and placed in landfills. Additionally, work blades have a tendency to kill birds.Not exactly clean energy.

    Hmm. Funny how aircraft propeller makers have known about that little nugget of info since the early 1920s. Wood propellers are built with a metal strip, usually copper or copper alloy, covering the leading edge to prevent such damage occurring.

    So you need all these fancy engineers and scientists to tell you something about air that anyone who rides a bicycle or motorcycle knows instinctively. Really!

    Of course they didn't get them right the first try, that's to be expected. Why do you think you don't see any Model Ts being built these days. I'm sure they're working to get better all the time and it's worth it.

    Looks like another government funded business required to install leading edge metal strips. Has anyone added up the amount of energy to produce and install these wind machines? What is the payback versus burning natural gas? My guess is the turbine will break and be destroyed before it is ever profitable.

    Should've went with nuclear energy, creates 300x less toxic waste per kwh than solar even. Green weenies!

    Put some weight on the tips of the blades.

    Umm engineers have known for at least a decade that wind farms are boof. What about land fragmentation throughout wind farm areas? Local fauna displacement during construction? Lets ask real questions

    So how much energy must a wind turbine produce before it surpasses the amount of energy used in mining the materials used in its construction, shipping those materials, all of the manufacturing and installation involved in putting a wind turbine in place? I’m willing to bet far more energy is used to manufacture and install, Service and maintain a wind turbine then it will ever produce.

    Drama, drama, drama, this is engineering not a brain dead TV show.  Just understand the problem and work on it.  But thanks for the technical information it the video.

    Kind of like all the migratory birds these things kill every year. I like how a migratory bird is considered an impurity.

    They don't tell you that to make these turbines creates more pollution than they stop, just like recycling creates more pollution than it stops
