Developers say this is a new fuel source which involves only wastewater and carbon dioxide. Biofuel production is within a network of floating four nine-meter plastic bags fulfilled with wastewater and carbon dioxide.
In a demonstration plant in California researchers have shown this system can grow enough algae to produce almost2,000 gallonsof fuel per year under ideal condition.
The technology will require an enormous amount of plastic bags. According to estimation, to produce 2.4 million gallons of algae per year would require 5 square kilometers of plastic bags necessary to be replaced annually.
