I do like the Aerovator. Seems much easier to build. But I suspect it will have to get in the way of some airline and bird migration paths.
but in both cases dealing with how to maintain things and replace worn parts seems like a major problem. You'd have to have something mounted on the cable/ribbon holding the whole system and put in a repair in the middle.
Neat ideas to think about in any case!
I never thought anything of it because I have been using psi for decades to to do strength calculations. Figure the force involved. Find the psi of the material. Figure the area * safety factor.
BTW Young's modulus is in the same units psi or GPa.
