Method and apparatus for CO 2 sequestration
First Claim
1. An apparatus for sequestering CO2 comprising one or more bioreactors configured as a series of vertically descending, horizontal baffles,wherein the bioreactor has a generally rectangular shape hanging vertically, having a height measured vertically and a width measured horizontally;
- wherein the horizontal baffles form an enclosed, continuous, serpentine channel from the inlet to the outlet of the bioreactor, each channel having a cross-sectional width measured perpendicular to the bioreactor height and width, the cross-sectional width being significantly less than the bioreactor height and width such that the bioreactors have a generally planar configuration; and
wherein the serpentine channel has a translucent wall, configured to flow a suspension containing algae in the presence of natural or artificial natural light, the serpentine channel translucent wall being made from a flexible polymeric material.

Abstract
A method and apparatus for sequestering CO2 using algae comprises a plurality of vertically suspended bioreactors, each bioreactor being translucent and including a flow channel formed by a plurality of baffles. A culture tank contains a suspension of water and at least one algae and includes a plurality of gas jets for introducing a CO2-containing gas into the suspension. The culture tank is in fluid communication with an inlet in each channel for flowing the suspension through the channel in the presence of light. A pump pumps the suspension into the channel inlet.
