Heliotrope: A Solar Powered Hot Air Balloon Flight System
Abstract
What it is: A roughly spherical balloon constructed from light duty painter's plastic (0.31 mil high density polyethylene) and darkened with air float charcoal powder. Balloons typically range from 12-40 ft across depending on mission needs. How it works: Sunlight shines on the balloon, heating the air inside. The density difference due to the hot air in the balloon is sufficient to lift it up to 80,000 ft in the air
