SkyScrub
AUTONOMOUS POLLUTION CONTROL
Autonomous electric mini-zeppelins that patrol urban skies using sextant-like precision GPS
to detect pollution hotspots, then deploy biodegradable soap bubbles that chemically capture
and neutralize particulate matter before falling harmlessly to earth.
Standing in a smoggy city center and watching silent zeppelins glide overhead releasing
iridescent soap bubbles that sparkle as they fall, and within 20 minutes seeing the air
actually clear enough to spot distinct cloud formations through the purple haze that
blanketed the skyline moments before.
