Growing Spirulina
Spirulina is grown on amonia-rich water and can be grown in large open ponds (known as raceway ponds) in a special container known as a bioreactor. Pond growth tends to take up a lot of space and water and can be open to bacterial infection resulting in the loss of whole crops.
Raceway ponds being used to grow Algae. This method can take up a lot of room and are susceptible to infections.
An example of a photobioreactor. This method allows for better control of the growing enviroment.
Hydroponics4life use containers to grow Spirulina, known as Photobioreactors (PBR). Phtobioreactors use light and a rich nutrient water which is constatly moving to allow for better quality of crop (in the case of spirulina it allows it to grow in tighlty packed sprials) and reduces the loss of water due to evaporation.
Bioreactors can be expensive but hydroponics4life is developing containers that are very cheap to build, easy to run and can be stored almost anywhere out of direct sunlight. They will help produce food for comsumption and sale in some of the poorest communties in the world.
Spirulina as fuel
Spirulina has a high carbohydrate content and is a very good bio-product to be turned into bioethanol and used to run cars, generators or farming machinery very easily.
In January 2009 a Continental Boeing 737 tested algae-based fuel in a 50-50 mix and the plane performed perfectly. The test pilots described the flight as text and no special modifactions were made to the plane, making the biofuel cost efficent and good for the enviroment.
