Abstract: A closed loop system for generating energy is described herein. The closed loop system can include a solar collector, a tank, and the combustor. The solar collector can collect electromagnetic energy from a light source including, the sun. This electromagnetic energy can be transported from the solar collector to the tank via a light guide. The tank is illuminated with electromagnetic energy and biomass grows in the tank. The biomass is transported to the combustor and burned to generate heat energy. This heat energy can be used to generate electricity.
