Repurposing old wind turbines this way.


Such a great form factor for this! I love it.

I’m surprised to learn that those wind turbine blades only have a lifespan of 20 years. Does that apply to the ones used in the U.S. as well?

I don’t know but it’s probably an issue of a load bearing, moving structure that is exposed the the elements 24/7. These things can’t be run to failure so some estimate of usable lifetime has to occur.

It is my hope that in the decade ahead, as fault detection and characterization matures it will make predicting end of usable life a thing. This not only does away with conservative estimates of end of life and allows each part to be used to its full usable life but it also eliminates failures for the most part. This will have a huge impact on reducing waste.
