Scientists hope to hugely reduce the cost of wind energy by removing the blades from wind farms, instead taking advantage of a special phenomenon to cause the turbines to violently shake.
Vortex, a startup from Spain, has developed the tall sticks known as Bladeless — white poles jutting out of the ground, that are built so that they can oscillate. They do so as a result of the way that the wind is whipped up around them, using a phenomenon that architects avoid happening to buildings and encouraging it so that the sticks shake.
They do so using vortices, which is where the company gets its name from. The bladeless turbines use special magnets to ensure that the turbines are optimised to shake the most they can, whatever speed the wind is travelling at.
As the sticks vibrate, that movement is converted into electricity by an alternator.
The kochi-muziris biennale is india’s first biennale for contemporary art being held in kochi. one of the festival’s biggest draws is legendary artist anish kapoor‘s ‘descension’, created especially for the event. kapoor — long renowned for his large-scale, invasive sculptural works —
sets visitors within the harrowing space at aspinwall house, fort
kochi, where a caged vortex of black water spins down a seemingly
bottomless hole in the gallery floor. a perpetually rushing whirlpool
churns into the ground, entrancing observers in its continuity, and
creating a spine-chilling atmosphere for those nearby. contained within
the circular gate, ‘descension’ naturally draws visitors to peer as far
down to its depths as they can, but it is kapoor’s masterful play with
boundaries that keeps them constantly intrigued.
Now this is pretty awesome. Watch the patterns in the fog behind that building (viewed from the John Hancock Center, Chicago). You can make out a swirling, alternating vortex pattern. The fog is defining a Von Karman vortex pattern.
