Konstruktion av en fotobioreaktor för odling av alger por Frick, Brage, Axelsson, Lukas, Neselius, Tobias

“…Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources. …”
