On older buildings, it’s not too uncommon to see the crowning touch of an ornamental weather vane — a rotation device which indicates the wind’s direction. But what happens when a bunch of weather vanes are put together on the same surface? That’s the question that American artist Charles Sowers answers with Windswept, a kinetic installation of 612 aluminium weather vanes placed on the facade of San Francisco’s Randall Museum — and revealing surprising results, as you can see in this video from Dezeen.

As you can see, the spinning blades don’t uniformly point in the same direction as one might expect, but rather show smaller diverse patterns and paths of the breeze. Says Sowers: ”Windswept seeks to transform a mundane and uninspired architectural façade (the blank wall of the theatre) into a large scale aesthetic/scientific instrument, to reveal information about the interaction between the site and the wind.”

More kinetic sculptures and more wind in the archives.

We’ve always loved the super tall wind-power turbines while speeding by on a train or in a car. Reaching tall into the sky, they are a marvel of sustainable kinetic power and so the kid often asks for videos of them…  

This time-lapse video shows the assembly of three wind-power turbines within a two-day period in June 2011 at Puget Sound Energy’s Lower Snake River Wind Project-Phase I, located in Garfield County, Washington. From the ground to the tip of a vertical blade, the 2.3-megawatt turbines stand more than 430 feet tall and weigh 340 tons. The boom on the crane erecting the turbines extends 390 feet into the air. When completed in early 2012, PSE’s newest wind farm will have 149 turbines capable of generating 343 megawatts of electricity, enough to serve 100,000 households.
