Two Korean industrial designers Kitae Pak and Inyong Jung, have created a caddy that generates energy from the kinetic energy of its movement. When you push it, this invention is called Electronic shopping cartAs you shop, its specially designed wheels convert kinetic energy into electrical energy, which is stored in a battery. It can generate up to 467 kWh of energy and reduce CO2 emissions by around 65.5 kg per year.
The project aims to provide an electric microgeneration system to the supermarket in question. The consumer has to leave the cart in a specific place at the end of their shopping, as we are accustomed to, this is where the energy stored in the car battery is transferred to a main storage unit.
