The competition also honored two runners-up; Alphabet Energy, a waste-heat recapture venture, and my personal favorite, MicroMidas, a company with technology to transform sewage into plastic.
The Open itself was limited to the entries from California, the Rocky Mountain Region, and the Pacific Northwest. However, a separate, parallel competition, run with the help of the Kauffman Foundation, offered a prize of $100,000 in services to entries from around the world. The winner in this, the Global Cleantech Open Ideas competition, was Replenish Energy of Puerto Rico, a company that uses micro algae as a source of fuel.
