3D printed objects aren't the strongest due to the way the layers are laminated together. I imagine the last place you'd want a weak join is on a 150+ foot long blade swishing through the air.

You betcha.

Especially since a spinning blade gets more efficient as it gets faster. Higher speed = lower torque for a given horsepower density, so a higher tip speed ratio (TSR) wastes less energy "twisting" the air downwind.

Efficient wind turbines run at a TSR of 6 or higher - which means that in windy conditions the tips are running at an appreciable fraction of the speed of sound.

If one of those puppies breaks off it's NOT the kind of baseball bat or boomerang you want coming toward you, whether flying or summersaulting along the ground. (Imagine a caber toss with giants and redwood logs.) Not to mention what the resulting unbalanced spinning does to the other blades and the pylon.

You don't need usenet for these, by the way, it's all torrent driven.

Usenet tends to be faster, however. Torrent download speeds are highly variable: fairly quick for popular files that everyone else is downloading at the same time, not so much for other files. I've had to leave many a torrent running for days or even weeks for it to complete. SABnzbd, OTOH, will usually pull anything that hasn't expired at 5.5-6 MB/s (bytes, not bits) over my connection, which is pretty much as fast as the connection supports.
