For a minute there I thought I had to get off my couch, when all the while the fact is we don't have to do anything much but keep things afloat for just a few decades more! In fact, we'd best shut up about PO, because if our offspring finds out we knew about it all along, they'll turn and wring our necks come 2036!
The Oz project, as I heard it, was a 1 km high guyed steel chimney and 27 km2 of greenhouses containing enormous black finned water reservoirs.
Saturn,
I went to the web site again under "materials" they wrote the chimney would be made of Reinforced high streangth concrete. And the turbines from lightwhieght Alloy (AL?) "as used in aircraft manufacture."
Steel would be a better option for building up, way up, just like the "Skyscrapers", and TV antenas.
Why use concrete instead of steel?
Does steel release the heat too (conducts) quickly, while concrete has the "thermal mass"/ heat sink ability to make the theorhetical science work?
Problem could come in by actualy trying to build such a thing out of concrete....
