The few billion tons I was referring to was the force required to 
support the beanstalk. You were going to have a several hundred or 
thousand mile long cable with counterbalancing loads? eww, the 
mass of the cable would rather eliminate any help. Anyway, this is 
turning into a engineering/physics discussion (which I'm happy to 
continue off list)

There is little advantage to doing so with those. However, other 
large structures like bridges, which are a parallel to beanstalks 
have been damaged or destroyed by terrororist or military force on

No point in having the thing if you can stop it falling, just use the 
grav stuff to transport the mass into orbit. It's powerful enough to 
hold up a beanstalk after all ;)

Too true... but it's probably a bit more 'high' SF than some of the 
flavours of FT. But hey, variety is the spice of gaming ;)
