Ah, but thats the rub. Vertical transport of mass is a waste of energy. Its the
main reason why the multi-floored mills along the rivers of the eastern US lost
out competetively to single floor factories elsewhere. Using a narrow
footprint/large vertical structure is economical for industries that involve the
transport of information, which is why you don't see automobiles being made in
skyscrapers. The bankers, lawyers, architects, and other executive disciplines
locate in such structures because their main product, information is relatively
massless and of extremely high value per lb. Software companies should be located
in skyscrapers, not in office parks.

But you knew this Anders, I posted this to the list three years ago... ;)
