A liquid dielectric is a dielectric material in liquid state. Its main purpose is to prevent or rapidly quench electric discharges. Dielectric liquids are used as electrical insulators in high voltage applications, e.g. transformers, capacitors, high voltage cables, and switchgear (namely high voltage switchgear). Its function is to provide electrical insulation, suppress corona and arcing, and to serve as a coolant.
Most microalgae produce their own nutrients by using sunlight in a photosynthetic process. However, the proprietary microalgae are heterotrophic, meaning they grow in the dark (in fermenters) by consuming sugars derived from plants that have already harnessed the sun's energy. By using standard industrial fermentation equipment, it is possible to efficiently scale and accelerate microalgae's natural oil production time to just a few days and at commercial levels.
