Title: Algae cultivation systems and methods with reduced energy loss

Abstract

An open raceway algae cultivation system includes a channel configured to contain an algae cultivation fluid. The channel includes a contraction zone having a width and a depth. A pump is configured to circulate the algae cultivation fluid in the channel. A width of the contraction zone decreases leading into the entrance of the pump and a depth of the contraction zone is greater than a depth of at least a portion of the channel located outside of the contraction zone.

Algae cultivation systems and methods adapted for weather variations

Patent Hazlebeck, David A.; Corpuz, Rodney

Algae cultivation systems and methods account for weather variations that can affect algae cultivation. In one system, an open raceway algae cultivation system includes a channel having a high section and a low liquid collection section. The channel is sloped to allow substantially all of an algae cultivation fluid in the high section to flow downwardly into the low liquid collection section. A barrier is removably positioned in the high section and a drain is positioned in the high section such that, when substantially all of the algae cultivation fluid has collected in the low liquid collection section, any rainwatermore »« less
