Abstract

We have innovated “The Energy Conversion System for Travelers” or the ECoST. With the fact that most travelers have wheeled cabin-bags, whilst walking, the wheels will rotate so why don’t we harvest electricity from this kinetic energy? We thus install our innovation, the ECoST, to the bag to generate electricity from the spinning wheels. The electricity is then kept in the storage unit and ready to charge your empty battery devices in an emergency case via a USB port. To make life easy, our ECoST was designed to replicate the power bank charging method; therefore, we can charge it by plugging it into any wall sockets. Our system was composed of two important parts, namely, the energy harvesting unit, and the energy storage unit. The harvesting unit was designed to convert kinetic energy from rolling wheels into electricity. During our walk, the wheels rotate, which gets the axle in the gearbox to spin and transfer the angular motions to the generator producing clean electricity. Thus our ECoST is indeed a Greenovation. The electricity then flows through a small wire into the luggage are stored in the energy storage unit. Replacing the conventional Li-ion battery, we opted for the most recent supercapacitor technology which exploits no chemical process which is more environmentally friendly. Without chemical reactions, they generate no heat. Thus there was no heat loss making the energy conversion more efficient. This removable energy storage unit can be plugged into any electrical outlet to charge to full capacity. Last but not least, with the recognition of our innovation, we have already been assigned the patent submission number (1703000492).
