Edit / in fact it was “Ms. Easton, a widow of Boston, MA wants to buy $1,000 of a penny stock, so the broker buys $10, waits for her purchase to drive the price up, and sells them at a profit before going out to a showing of one of those exciting new moving pictures.”

The ISS already has issues with structural fatigue which seem to be worsened by thermal expansion. Having one side of your station red hot and another at room temperature is a big temperature differential and what faces the sun and heats up on one side of the orbit will be in shadow and cooling on the other side. And the bigger you make a physical system, the worse problems get.
