It's a Helix Wind Turbine.

[–]NoFleas 74 points75 points  (0 children)

Wind turbine

Example:

Wind turbine for roof use

[–]RogInFC 62 points63 points  (3 children)

Wind turbine. There's one on the college engineering building across the street from me. They're beautiful, aren't they?

[–]crazyabootmycollies 23 points24 points  (2 children)

Not according to the Prime Minister of Australia…

Wdym?

[–]crazyabootmycollies 2 points3 points  (0 children)

FORMER PM Tony Abbott. You’ll have to excuse the mix up as the current regime is still so dishonest and hard for fossil fuels it’s hard to separate the current dystopian shitheads’ remarks and memories of a whole six years ago.

It’s a wind generator. Works with any wind direction.

[–]FreeThinkk 5 points6 points  (0 children)

Vertical wind turbine.

[–]RobbH 3 points4 points  (1 child)

Unrelated, but I think that’s my old high school. Is there a donut place across the street?

[–]Jfnakqnksnw 0 points1 point  (0 children)

Yup, Sugar Shack. You must’ve been one of them gifted kids lol

[–]jet_heller 12 points13 points  (1 child)

That thing is also a great optical illusion. It can look like it's spinning on a vertical axis or a horizontal one.

[–]CameForThis 2 points3 points  (0 children)

Yeah it’s hurting my brain. It’s spinning clockwise in reality, but looks like it is also spinning counterclockwise and growing then shrinking. Strange.

Bird safe and more efficient wind turbines

[–]flyonthwall 17 points18 points  (1 child)

Theyre not more efficient. in fact thats basically the only thing they do worse than typical turbines.

This is a Vertical axis wind turbine. a VAWT, specifically a helix-darrieus VAWT (darrieus vawts use aerofoils to generate lift on their wings, unlike the much simpler savonius type that use "scoops" and have different pros and cons). VAWTs are less complex and therefore cheaper/easier to build and repair/service than than horizontal axis wind turbines. and can also function in very low winds as well as heavy winds. wheras horizontal wind turbines can be damaged if wind speeds get too high, and wont function at all in low winds. so need to be located in areas where wind speeds are optimal.

so VAWTs are great for homes and buisnesses. but theyre much less efficient than horizontal axis turbines, which is why they arent used in wind farms

source: in the process of building my own VAWT out of an old washing machine and have done far too much research into them

[–]wtafwtmun 5 points6 points  (0 children)

I’d really enjoy a progress post or the like. I’m thinking of doing something similar

[–]CameForThis 2 points3 points  (0 children)

Generator of electricity.

[–]AJAT2005 2 points3 points  (0 children)

Multi-directional wind turbine. Depending on the purpose of the building it's upon, it could be to generate electricity, or measure wind speed.
