That extremely huge blade that don’t weigh shit would probably not be able to handle the stresses involved to rotate the turbine shaft. Most likely tear themselves to pieces.

From what I understand, this material (while light) is also very strong.  Also, it can be reinforced to some extent and still be lighter than current materials.

The weight of the materials isn’t what makes a windmill hard to turn.

Sure it does.  The heavier it is, the more friction at the base, etc. of the low speed shaft; hence, harder to turn.  Lighter means less friction and more efficient use of the energy from the wind.

Can I haz newz artical?

Awesome! Where can we get one?

You mean that is what you call a dandelion seed head? Why have I never heard this?

Mind blown by my own obliviousness — “clock”? Who knew?

but write-up makes it sound like they designed at the ever-popular thickness-of-a-human-hair scale.

It’s like all the cool stuff I hear about carbon nanotubes and how they will revolutionize the world, except we can’t crank them out easily and cheaply.
