Microalgae biofuel research. Researcher placing cultured microalgae in a thermostat cabinet. These algae are being grown as part of the Shamash project, which aims to produce biofuel from autotrophic microalgae such as these. This cabinet allows different parameters to be controlled, including brightness, acidity, temperature, and nutrients and the reaction of the algae to them to be analyzed.
