Not much good as a reliable method for crossing oceans that are 
prone to having heavy sea conditions, moderate to large waves 
prevent the use of Ekranoplans. Good for inland seas and other 
large calm bodies of water, perhaps featureless flat plains too.

Beanstalks are a waaaaaaaay major engineering task, and very 
demanding of materials technology, 20,000+ km long stalk with 
enough strength to perform the task. Not cheap to build either.
"Hey.. it costs a dollar a ton in fuel to pull things up it... but it

a googledollar to build it." ;) Not too great if someone blows it in 
half. Half floats away, the other half falls on you.
Then again, perhaps you could use solid state antigrav to support 
it...
