School project - Libertas is an energy generating laptop case, utilizing cutting-edge technologies to create a high quality solution for out of home workers. Based on insightful research and interviews with specialists in the matter, we are proposing a system that harvests mechanical energy from a moving mass and converts the harvested mechanical energy into usable electrical energy: enough to charge a laptop. The proposed system incorporates three different technologies through a three step process: energy generation, energy storage and energy transfer.
