Patent ID: 8415142

Claim:
A system for removing CO 2 from air using algae, the system comprising: a culture tank for a suspension of algae in a liquid; a bioreactor in fluid communication with the culture tank to absorb CO 2 and grow the algae, the bioreactor having a plurality of translucent, substantially horizontal channels therethrough in an alternating horizontal arrangement from top to bottom of the bioreactor and vertical end channels connecting adjacent substantially horizontal channels to form a continuous flow path for the suspension from the top of the bioreactor to the bottom of the bioreactor, the enclosed horizontal channels and end channels being made from a flexible polymeric material and the bioreactor being adapted to be hung vertically for gravity flow of the suspension through the continuous flow path; a monitor determining the growth of the algae in the channels and adjusting a parameter of the suspension of algae to maintain a predetermined range of the parameter; a separator to separate grown algae; and an extractor to extract biomaterials from the grown algae.
