Bio-Science meets Domestic Science
Bio-fuel researchers at the University of Michigan have come up with a novel way of extracting oil from algae.
They are mixing Domestic Science with Bio Science! They have found that pressure-cooking algae allows extraction of oil in a simpler and more efficient way.
The pressure-cooker method of oil extraction has not been used to date AFAIK. The accepted technique is to grow the most oily types of algae, then dry the algae before extracting the oil.
The pressure cooker method can extract oil efficiently from less oily varieties of algae. The process also eliminates the need for drying, which wastes a lot of energy and time.
