But one of the greatest challenges in creating biofuels from algae is that when you extract the oil from the algae, it kills the organisms, dramatically raising production costs. Now researchers at the U.S. Department of Energy's Ames Laboratory and Iowa State University have developed groundbreaking "nanofarming" technology that safely harvests oil from the algae so the pond-based "crop" can keep on producing. http://www.physorg.com/news158333205.html Nanotechnology Tue, 07 Apr 2009 14:27:13 EST news158333205
