Researchers heat algae in a pressure cooker to produce crude bio-oil
If you’ve read even a little bit about potential sources of biofuel, you’ll know that algae is one of the big ones. During photosynthesis, the unicellular aquatic plant turns sunlight and carbon dioxide into oil. It’s grown in ponds, where it’s not taking land away from food production, and yields much more oil than other biofuel crops, such as corn or soybeans. Researchers at the University of Michigan have recently come up with a method of getting algae to give up its oil more quickly and efficiently than has previously been possible - they pressure cook it.
