space elevators & untra ultralight materials

[Wesley Bruce]

A key to space elevators, solar chimney technologies and big flying jet 
stream windmills is *zero weight building materials*. I have a design 
for such a material; an expanded foam filled with hydrogen and helium. 
Its meant to be Buoyant up to 5 km and ultralight but stiff above that 
hight. Think what it would do for rocketry. I'm trying to find the right 
reinforcing materials and chemistry. As I said before; will someone give 
me a LAB!
