Argument: Algae pools can become contaminated and less efficient

Issue Report: Algae biofuel


“Leave the algae alone”. Low-tech Magazine. 4 Apr. 2008 – “low-tech methods (comparable to growing corn, soy or palm trees to make ethanol or biodiesel) are being left behind for more efficient ones, using closed glass or polycarbonate bioreactors and an array of high-tech equipment to keep the algae in optimal conditions. Even though some companies still prefer open ponds (like the PetroSun plant that started production last week), this method has serious drawbacks. The main problem is contamination by other kinds of algae and organisms, which can replace the energy producing algae in no time.”
