I think a good corrosion resistant steel, would be even better then concrete.
It is strong compressive and tension wise. It is cheap and easily produced in
large quantities. It is probably lighter then a concrete sphere. I also believe
it would be easier to work with then concrete, considering many people know how to
make large steel frames and weld them together. Concrete usually would be poured
in molds and then attached at joints which could lead to some problems.
One thing for the concrete side, weren't America's Liberty Ships during WW II
made out of concrete.
What about natural wood or engineered reinforced wood or other recyclable
materials, maybe cardboard!
Sincerely,
