Solar Windcatcher

I noticed an idle thermal relief vent spewing steady, hot exhaust right next to a cluster of discarded Mylar insulation sheets. With my Flying V secured on its back harness, I snagged a lightweight titanium strut and pierced four triangular foil flags onto its tip. Planting the spindle into an empty magnetic ball-bearing collar on the railing, the thermal updraft instantly caught the reflective wings! The whole assembly whipped into a furious, glittering turbine that whirred like a miniature aero-dynamo, kicking up a delightful vortex of sparkling dust right against my chest plate.
