One of the technical challenges with growing algae is maintaining a rapid growth rate and not having "culture die-off" where the algae stop growing and die. Here is a photo of the plastic bags in Solix's bioreactors which take in carbon dioxide and water to stimulate growth. Each end of the bag lifts periodically to send some algae off for collection and then processing into sellable products.
