The Cleantech Open crowned EcoFactor, an entrant in the Smart Power category from California, as winner of the 2009 Cleantech Open, a business competition created to find, fund, and foster startup clean technology companies. EcoFactor has designed a software system that communicates with home thermostats to reduce energy use. EcoFactor won $250,000 in cash and services.
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.
