I'm no engineer, but this sounds like a pipe dream (no pun intended).

Those radio towers are built to a height for a specific purpose, not due to engineering limitations. The solar tower is to a sound engineering design which should be challenging, but not impossible, to construct.

Instead, they report that the plastic traps in heat and moisture, much like a greenhouse. Plants actually thrive under there.
