Energy Conversion System For Travelers (Ecost), Thipok Bovornratanaraks Jun 2018

Energy Conversion System For Travelers (Ecost), Thipok Bovornratanaraks

The International Student Science Fair 2018

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 ...

A Swing Generator Using Water Power Produced By The Wind, Ruka Ozaki

The International Student Science Fair 2018

I focus on various kinds of natural energy sources, especially wind. Wind power generation is the most-used method of electricity generation using wind power. Wind power generation has many merits; it achieves high efficiency of electric power generation, it can generate electricity even during the night, it doesn’t make any hazardous materials. However, there are not only merits but also demerits. It can cause bird strike, environment disruption from noise and low-frequency wave. And besides, we must comply building laws when we build wind power generators. Thus I built ‘a swing generator using water power produced by the wind ...
