The E-Bag is a cooler that can keep your lunch or drinks cool without any ice packs. The cooling energy is derived from swinging the bag to and fro as the user walks along. The bag's handle, which is attached to a dynamo, rotates which charges a battery. The cooling action is derived through Peltier technology which is like a solid state heat pump for heat transference. Three LED lights indicate cooling status.
Apor Püspöki is the designer who came up with the E-Bag. He is a product design student at Moholy-Nagy University of Arts and Design in Budapest, Hungary. He said, "I wanted to make a point about the way urban life goes with increased energy consumption. We have responsible design thinking."
