SAVE PETROL







First, grow colonies of Botryococcus braunii algae (a species especially prone to storing fat) in long, thin, transparent plastic bags in the desert.




As the colonies mature, starve them of nitrogen [2]. The cells react to the low nutrient supply by entering survival mode and producing extra fats. When they’ve created enough fat, collect the cells and break them apart [3]. Filter out the large organelles and cell membranes, and then use solvents like methanol to separate out the fats from the water-soluble proteins and sugars [4]. Purify the collected fats, and evaporate the solvent [5]. Finally, put the fats in a chemical reactor to transform them into biodiesel (a process called transesterification)
