🤬🤬🤬🤬🤬🤬🤬🤬 https://newatlas.com/environment/balsa-wood-wind-turbine-blades/ "As a result, chunks of old blades – with the wood and plastic still bonded – are typically just burned in cement factories as a source of raw material."

This just adds to the cost of building and operating these abominations. These things can not compete on a cost per Kw hour with conventional plants. We have these things because some people believe that man is so powerful we can affect climate on a global scale. The climate has been changing ever since this rock started cooling. It will always change. Isn't it a good thing that man was making enough carbon footprint to cause enough global warming to bring the earth out of the last ice age?
Wind turbines are a bad idea.

We'll see how good they work with one blade missing.😁

Well, I suppose that's better than just burying them in the landfill.

We need to start a wind turbine blade recycling company .

Looks like the Spar is balsa. Funny how these companies can buy up all the balsa and ruin so many others. Hopefully they will find better manufacturing techniques that doesnt require balsa.

Turbine Windmills are one of the greatest and long running lies of the Left.

4 million dollars for "one" land based Windmill and they serve absolutely no value.

Off shore Windmills? I have no accurate information on theses but some say 6 million plus.

Ya gotta just love the Left with their propaganda about Green Energy and Wind Turbines which are a huge part of the scam.

Looks like the modeling community pays a price for this.

Man effecting "climate change" is like an ant climbing up an elephants leg with "rape" on his mind.... good luck.

All that good stuff going to waste! It makes me think of a story from back in the late 1940s, when money was scarce and balsa was even scarcer: some young modellers in England found a scrapped Gloster Gladiator and discovered that the fairings on the undercarriage legs were BALSA! They hacked off as much as they could get, and actually managed to put it to good aeromodelling use. They'd have LOVED a turbine blade.

Avaiojet · « **Reply #9 on:** September 28, 2020, 08:45:17 AM »

Recycle the blades?

Probably keeping people from doing this.

It'll bring interest and knowledge to the Windmill scam.

I vote for recycling if someone can figure out how to give it a go.

Just a question. When you say that a windmill cannot compete with the power other plants make.Are you considering the actual cost to completely undo the the damage that burning oil does ? Seems if you held gas and oil type power plants to zero emissions. Then the cost might well be the same ? The issue is NOT cost. It is people and enforcing rules. Which all comes down to PEOPLE!

How many years have we had coal and oil fired power plants. Nuclear power came to be with the dangers of what could happen. I see these wind mill generator farms growing all over our country destroying the scenery. If they are so great, how come they are not providing the power they are supposed to do? And also how much of the balsa in one blade is useful?

Dan McEntee · « **Reply #13 on:** September 28, 2020, 08:29:54 PM »

It's been reported on here and in articles that the balsa used is ground up, then mixed with resin for use in these monstrosities. In the one photo posted of what looks like a shear web or spar, it resembles flake board paneling. I think that is verification of it.

Jim,
I agree that pollution of all types must be reduced. Are you including Carbon Dioxide as a pollutant? If all Carbon Dioxide disappears, all Oxygen breathing lifeforms on this planet disappear. No Carbon Dioxide no photosynthesis, therefore no Oxygen. No Carbon Dioxide no vegetation. I cannot accept that global climate change is being caused by man. How can we explain how the planet came out of the last Ice Age without man causing the warm-up? Another problem with pollution is the fact that the USA has one of the largest if not the largest industrial economies but we are no where near the greatest polluter on the planet. The Chinese probably produce 10 to 100 times as much air pollution as the USA. Los Angeles has air quality problems, Denver has air quality problems, Wuhan China has air that makes the air in either of those look like an Alpine meadow. I can speak from experience, I have been to all 3 cities.
We must continue to work on pollution. I believe that wind generation is inefficient and overall an abomination. What about the noise pollution and the damage to bird life around those things?

I wonder if any of that balsa could be reused for model airplanes.

Look at the photo in reply #7. Do you know what flake board is? It's a cheap substitute for plywood. They take flakes and chips of shredded wood and bond it together to make a sheet of wood. Not the same as particle board. Look at that phot closely with that description in mind. What you are seeing is balsa flake board, or at least that is what it looks like to me! No way to reuse that for hobby use except for making flight boxes!

Great Idea- how do you start? About all you can do with windmill blades, which generally are a mixed composite of epoxy, balsa, dense wood, fiberglass, and sometimes other plastic, is burn them for heat and then mix the ash with some cement to make it solid enough to handle. A burner for this stuff will require a completely new design to contain the ash, prevent build up inside, and separate the ash.
It will NOT be economical and will require subsidies, in addition to the construction subsidies. Likely the ash will make a useful extender for cheap, non-structural concrete, again with a separate subsidy.

Or maybe burn them in one of those generating plants designed to use garbage as fuel?

Maybe we should have a contest to see what can be built with the blade leftovers. We (control liners) are a very resourceful group of people. I betcha someone could make this work.

Dennis Toth · « **Reply #21 on:** October 14, 2020, 07:43:03 AM »

What you are seeing are blades that are part of an upgrade to new technology. They can not be reused or sold because of US tax law that requires material and in some industries (like model engine manufacturing) tooling to be destroyed in order to claim business tax deductions. These are perfectly legal standard business tax deductions that have been in place long before wind turbines were deployed. It is a shame that the tax laws have not been amended to allow old materials to be sold to say a third party and have the government receiving some portion of the sale proceeds.

Many of the newer turbine blade designs have switched from the end grain balsa that was used between fiberglass blade shell skins to structural foam as used in some composite aircraft wing designs. This provides a stronger blade that can be made longer which increase the amount of energy they can capture (basically adding a bigger sail to caught more wind). The theoretical max efficiency of modern wind turbines is 59.3%, most current designs capture between 45 -50% of the available energy. The big gains have come in the lower wind speed area with new blade designs allowing power generation at wind speeds as low as 6 mph. Free fuel does wonders for cost, most systems pay for the equipment and installation and start being profitable in about 8 months after coming on line.
