Non-electric pressurized cooler


The Ann Richards School for Young Women Leaders InvenTeam invented a non-electric cooling pressurized container to preserve food or medicine for those who do not have access to electricity. The container is periodically pressurized with mechanical energy through a bike pump and the pressurized air is then released, making the container cool. Unlike current refrigeration systems, it uses no chemicals, and is compact and transportable, weighing less than 30 lb. The setup time is less than ten minutes. The stainless steel container is easily cleaned in under 2 minutes. The invention can be used in developing countries or in contexts such as camping trips, food trucks, and military camps around the world. The alpha prototype cost $200 to fabricate.
