Oregon State University develops biodiesel from algae

The Oregon State University (OSU) is working on a new process that could draw up to 60 % oil from an algae farm. It has two small photobioreactors built to grow microscopic algae of both fresh water and salt water varieties in a closed system at the OSU Sustainable Technologies Laboratory. The biggest challenge is separating water from the micro algae he is testing - Chlorella and Dunaliella - which must continually be mixed with carbon dioxide and light as they grow. A combination of straining and centrifuging is the current method of extraction.

Nature gave us oil from algae; perhaps we should try Nature's way again
