Could algae power your car? In the search for new energy sources, scientists are turning the green goo into oil.
While the technology itself is not new, Japanese scientists say they believe oil from aquatic algae could become an important raw material as biomass technology improves and the world looks for oil sources other than those in the ground.
Experts also say algae will be a more sustainable biomass source than sugar cane or corn as the global population expands.
