Biofuels: Algae?
¥Algae may be the long term biofuel of the future.
Still some significant technical problems to overcome
Some BIG Advantages motivate research:
¥Yields of oil from algae are orders of magnitude higher than those for traditional oilseeds
¥Algae can grow in places away from the farmlands & forests, minimizing damage to the eco- and food chain systems.
¥Algae can be grown in sewages and next to power-plant smokestacks where they digest the pollutants and give us oil!
