An Arizona energy company is betting big on algae. PetroSun Biofuels has opened a commercial algae-to-biofuels farm on the Texas Gulf Coast near scenic Harlingen Texas. The farm is a 1,100 acre network of saltwater ponds, 20 acres of which will be dedicated to researching and developing an environmental jet fuel.

PetroSun's gameplan is to extract algal oil on-site at the farms and transport it to company bideisel refineries via barge, rail or truck. The company plans to open more farms in Alabama, Arizona, Louisiana, Mexico, Brazil, and Australia in 2008.
