Warner bros to the rescue

  1. Sep 16, 2008 #1
    You know those fans they use in movies to simulate wind? The really big powerful ones. How many of those would it take to counteract a hurricane? How many just to drop it down a category. I think you can get one to blow at hurricane force can't you? If cost wasn't a factor could enough of those fans be built and set up to stop a hurricane?

    Let's see what would do an inadequate job at saving Galveston.

    The main part of the town is about 10 km long. Let's say the fans are 1m in diameter (I doubt it). So a huge rack of fans 10,000 at the base and say, what 100 m high? just to protect the buildings?

    So, one million of these fans, on the order of 1000W each. A thousand megawatts of electricity to power them. And still, I doubt they'd stay up, and if they did, they would create a small pocket of extreme turbulence (as two masses of wind collide).

    I say we call the Mythbusters!

    maybe we could at least make a hurricane veer off and hit mexico instead of us?

    How about dropping giant ice cubes into it to cool the water down?

    That's what I always thought (well, actually stir the water so the cold water from the bottom comes to the top).

    How do you think the hurricane got started in the first place?

    When you drain a sink and that little whirlpool forms I know from experience that it doesn't take much to totally destabilize it. Can a hurricane be broken up if just a portion of it is disturbed? Say an H-bomb dropped into the middle. Forget about the radiation and the danger. Would it stop a hurricane?

    It was that F-ing butterfly in Australia.

    That's a better idea, the high sea surface temperatures put a lot of energy in those storms.

    How about tugging in a big chunk of (Ant)arctic sea ice into the gulf?

    :uhh: What about the wind getting sucked toward the fans from the other side?

    I wouldn't want to be the one in charge of unplugging them after the storm surge hits either. :surprised

    Do you not know? all one needs is some actors from a B movie and the problem will be solved in 90 minuted, 30 is they shoot the actor playing the government science specialist.
