And looks like the addition of extra materials to strengthen the turbines might reduce their ability to be recycled??

The turbines near here locally apparently the blade tip speed is already near 270kmh, even though they look like they are only doing 30rpm

Soda bottles used to be made out of glass because plastics would stretch under the pressure. But glass soda bottles sometimes explode. PET plastic was discovered about 40 years ago. It can withstand the pressure without stretching. A two liter PET plastic bottle can withstand about 200 PSI.
A pressurized PET plastic cylinder might he the strongest building material for its weight and least expensive. It is flammable, but if it is pressurized with CO2 it would be like a fire extinguisher.
If you made a giant one kilometer square multi hull sailing ship out of 100 meter long, ten meter diameter pressurized cylinders, it could harness the wind energy with ubderwater propeller blades that are much smaller than giant turbine blades. Try bending a plastic Coca Cola bottle after it has been shaken up. A soda bottle can easily withstand a hurricane.

Do you know that a the Fibinacci sequence is the most efficient wind turbine.
|
Maybe it is partly a learning thing?

A far better question is , "why are they not contra rotating" ? Like the last of the WW2 pre-jet super propeller aircraft.

And I thought 5MW was large first time I saw one...
|
What happened to all the unconventional turbine designs that were around 15 years ago. I remember there was a vertical helical type that had most of the mass at ground level. Wouldnât that be easier to maintain?
|
Why isnât the square cube law preventing Chinese from building these gigantic wind turbines?
|
I think you're being too theoretical. You probably need to see it from the chonese point of view.
|
Just use tofu. Seems to work well in other Chinese construction projects.
|
Just go nuclear instead. We have already solved the energy crisis.

Interested to see how Kitemill will progress. Progress has been too slow.
So much wind over 500m.
