Bad statement, Rob, as usual. Sounds like you have only a nebulous idea of the point. There is a reason elevators aren't built with bungee cables, Rob, but it sounds like you have no clue about that. <G> > The cables do stretch over time, but they are not used to "level" the > elevator at each floor. Bungees stretch much more than steel and much more quickly, Rob. Quite different than steel cables.

When someone gets onto the elevator, the bungee stretches. Do you think these feedback systems are built to rapidly reel in and out quickly enough and long enough lengths of bungee to counteract the bouncing up and down as people get in and out and keep it perfectly level with the floor? Cause it sounds like this absurdity is what you are claiming. Either that, or you just totally missed the point. -- "Erik Reuter" <[EMAIL PROTECTED]> http://www.erikreuter.net/ _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
