The news has been abuzz the past couple of weeks with news of rotating towers, which will magically extract lots of energy from the wind, and with this abundance of energy, will be able to rotate their individual floors to face any aspect. There are some nice 3D rendered architects drawing on the internet at the moment, which seem to have captured everyone’s imagination. It's a lovely concept in the 3D playground of the conceptual architect, and whilst I can see that the idea might take off in a virtual world such as second life...I'm not sold on the idea.
There are a number of reasons. Gazing into my green ball, I think that the engineering challenge is... not insurmountable - but impractical.
I. I've had the pleasure to visit a few different countries in
II. Consider all the unexpected harmonics that will be set up in the central core, by a combination of rotating floors and wind turbines rotating. The Millenium Bridge in
III. Car lifts... The architect of one of these towers, envisages lifts in the central spine of the building, which you can drive your car into be whisked up to your respective floor, where you can park you car and get out onto your rotating room. This is a dumb idea for a number of reasons. I've been living in a block of flats with a car park out back with a pair of car lifts that move cars between two floors. Whilst it looks hi-tech, I am pleased that I have a ground floor parking space. I've had to call the fire brigade to get people out.
IV. The wind turbines. Sandwiched between two floors (which in themselves will likely induce turbulence?) how much wind energy are these turbines really likely to capture? Presumably in order to flow the wind needs to strike the building perfectly perpendicularly - the turbulence created by the adjacent floors - I am sure will disrupt any hint of laminar airflow.
It's a pretty idea, and I'm certainly not a luddite that dislikes big thinking, but what I do object to is fundamentally unsustainable ideas being jazzed up with a bit of EcoGeekery and palmed off on the open-jawed public who look on with wonder as sustainably sound.
There are some wider questions that we need to be asking in relation to tall buildings, and a bit of green window dressing doesn't go far enough to achieve the radical change required.
