Hydrogen-Fueled Gypsy Zeppelin

An autonomous self-regenerating hydrogen-based zero-emission low-cost low-tech nomad houseboat airship. Wow. What an idea! Lieven Standaert, a Dutch engineer, architect and science teacher, has designed a ship that makes its own energy, using its propellers to generate hydrogen for fuel. The tagline? “Powered by wind, fueled by rain.”
