But how does it work?  Just by swaying?  How does that stop the building. -- Posted by scalywag66 at 9:28 am on June 25, 2008 I think that's also going to be used when construction of the Al Burj is completed. It's being built not far from the Burj Dubai and is supposed to at least twice it's height, literally scraping the sky -- Posted by shadowpool at 9:30 am on June 25, 2008 Quote: from 420Mike at 1:21 pm on June 25, 2008 Thats cool.. But how does it work? Just by swaying? How does that stop the building. A huge hanging ball like that will tend to want to stay in one spot.  So when the building sways, the ball wants to stay put and it slows the building down.  I think.  Something like that.   -- Posted by 420mike at 9:34 am on June 25, 2008 Quote: from shadowpool at 12:30 pm on June 25, 2008 Quote: from 420Mike at 1:21 pm on June 25, 2008 Thats cool..

So when the building sways to the left the ball stays to the center/right and pulls the building back towards it.  That makes sense.
