Rotating Solar-Powered Skyscraper 267

PieEye writes "Wired is pointing out a recent Gear Factor blog entry that highlights a new skyscraper in the works which will be solar-powered, and what's more will rotate with the sun. From the article: 'The completed tower will offer 200 expensive apartments for people who want to spend lots of money to screw up their circadian rhythm. Singh said they want to build many more such towers, with one for every time zone.'"

    But seriously: How exactly is a rotating building meant to mess up one's circadian rhythm [wikipedia.org]? Does the blogger think this building is rigged up to do a lap of the Earth each day? It's spinning on the spot!

If your workplace is like mine, they probably have a deal with some internet company which regularly sends me photos of my nextdoor neighbour and her antics per email.

          You could build it in sections stacked on top of each other, with each section able to rotate ±30 degrees or so, then (since the bottom section would be fixed), each next higher section would have a greater cumulative maximum angle. This could then be an extra added benefit to the more expensive upper units, because they'd have more variety in the view.

          Of course, the other thing you could do is just put all the mechanical stuff in a non-rotating center column, which would make a heck of a lot more sense anyway because you've got to have at least one set of stairs for the fire escape, and putting that in the rotating part seems pretty stupid...

    Suite Vollard [emporis.com] was the first rotating tower of the world, however it's not solar powered. Here's some facts (excerpts from the link):

    - This building is the only one of its kind in the world, as each of the 11 apartments can rotate 360.
    - Each apartment can spin individually in any direction. One rotation takes a full hour.
    - The facades are composed of double sheets of glass, in different colors (blue, gold, and silver) on different floors. This gives a spectacular effect as the floors turn in different directions.
    - The apartment rings rotate around a static core used for building services, utilities, and all areas which require plumbing.
    - Suite Vollard was a case study for more than 30 companies in Brazil and one from Germany.
    - Each apartment was sold for approximately R$ 400,000.00 ($US 300,000.00).

    Dubai's Kulkarni QS will manage the project, while the task of rotating an 80,000 tonne tower through 360 degrees over a seven day period has been handed to Nick Cooper, managing director of Bennett Associates, the British engineer who designed the drill machine that bored the English Channel Tunnel.

    Dubai is having an insane skyscraper boom. 205 high rise buildings completed, 333 under construction. (Los Angeles: 465 completed, 11 under construction.) Not because of space constraints. There's plenty of open desert nearby. It's ego, enthusiasm, and money.

    1) The building does NOT keep one side at the sun all the time.

    It rotates a little bit all the time, giving everyone a changing view. The solar powered bit is on the ROOF, not the side.

    2) The amount of power needed to rotate the building, assuming it is round, is fairly low. You are just paying for the friction, which unless you are a fool, is almost all on the ground floor, where it meets the non-rotating base. There is no 'core' that does not rotate, - that would just create more problems, starting with increased friction.

    3) New York City (and many other major cities) has several buildings with a rotating top floor that does this already. They usually contain restaurants, complete with full water and electricity.

    4) Electrical hookups are simple. They work fine on a brush contact, again only on the BOTTOM floor.

    5) Sewer hookups are also simple. In the bottom floor, there is a large pipe. Beneath the pipe is a gigantic inverse ring, that funnels to a pipe. It does not matter that most of the time the inverse ring is open, stuff falls down into it.

    6) The only problem is the water intake, to get water to the building. This can most easily be done in the center of the building, with a pipe connection that is water tight, but low friction seal, allowing rotation.
