Gigantic Aluminium Spiders

Might take the CGI with a grain of salt though. AFAICT the company has existed for 4 years, has 7 employees and no actual office address. They own zero physical assets. Seems most likely they're trying to do just enough to get some patents so they'll be bought out by one of the large offshore service companies and make a nice profit.

You gotta be the weirdness you want to see in the world! Let's learn to weld aluminum, and make our dreams come true.

If you want something industrial, art, giant, and sometimes spider, there's always Storm King! :)

(It re-opens in April, if anyone happens to be in New York and hasn't visited Storm King, I really cannot recommend it enough, it's a lot of fun, Dia too, Earth Room and Beacon are magic but honestly they're all amazing, so fun! https://www.diaart.org/visit/visit-our-locations-sites)

If you want industrial giant spider, Kumo: https://www.youtube.com/watch?v=_E1PpbncR20 is a must see. "Les machines de l'île" have other beasts of the same kind: https://www.lesmachines-nantes.fr/.

For crane geeks, that _is_ pretty exciting. :)

You're not unreasonable for expecting something at least vaguely spider-like. This just looks like a big crane for assembling big wind turbines.

Is the "spider" part supposed to be the web-like aluminum frame of the crane? That seems like a stretch, but it's the most charitable interpretation I've got.

> We have our space elevator!

Out of context, that sounds like a kite. Can it be used in locations that are not very windy (like, for example, space)?

Unfortunately not, there is no wind in space.

Thanks, it looks like what I had been hoping for is called a "spider excavator".

Indeed, but this company's cranes do not to my untrained eye resemble spider cranes.

Totally underrated film that doesn’t get the praise it deserves.

Unless something goes wrong, and they crash into a ferry.

When edge cases become catastrophic, engineering gets hard.

Large ones are higher up and windy gets faster the higher you go. Though I think even if that wasn't the case it's more efficient to build a few big turbines than many small ones.

I believe power increases exponentially with scale. Essentially, Area = (pi) * r^2 (but much more complex given it's turbines).

This article has a good summary: https://www.energy.gov/eere/articles/wind-turbines-bigger-be...

* 89ft - 0.2mw

* 173ft - 0.9mw (2x radius, 4.5x power)

* 410ft - 3mw (2.5x radius, 3x power)

* 820ft - 17mw (2x radius, 5.5x power)

In addition to the other replies, bigger rotors achieve their power at lower rpm. That's because blade tip speed needs to stay well below the speed of sound, at all sizes. Where small, hectic rotations are annoying, the large ones appear majestic. They are seen very far, but blend in much better. The small turbines are the ones that are catching the eye.

You can spend many hours with a mix of different turbine sizes in view perceiving that difference without really being able to put a finger on it. But when you do realize how that plays out, you will never ever consider two smaller turbines where a larger would do. Chances are you'd even prefer a larger one over a single smaller.
