I am curious to know if the St. Louis Gateway Arch would be strong enough to act as a support structure for a giant vertical axis wind turbine.
I way I am envisioning this being constructed is that a radial shaft bearing block could be installed just below the top of the Arch and a combined radial & thrust bearing block could be constructed down at ground level. 600 feet of steel piping would be installed between the top bearing block and the ground level bearing block. The turbine blades would be attached to this steel piping and the rotating steel piping could be connected to an electric generator on the ground via some sort of pulley and chain setup.
Could the St. Louis Gateway Arch be used as a support structure for a giant vertical axis wind turbine?
Here is a drawing of what a vertical axis wind turbine might look like positioned underneath the Arch:
