The Aquaduct Mobile Filtration Vehicle, developed by Adam Mack, Brian Mason, John Lai, Paul Silberschatz and Eleanor Morgan from California, USA, was the Grand Prize winner in the “Innovate or Die” Pedal-Powered Machine Contest this year.

"The competition sponsored by Google and bike maker Specialized, asked people to create Earth-cooling inventions based on the simple mechanics of the bicycle and attracted 102 entries from around the world."
