CU Inventors Receive Gold Medal Award at International Exhibition of Inventions

           At the 46th International Exhibition of Inventions in Geneva, Associate Professor Soorathep Kheawhom and Mr. Kijchai Kanjanaprapakul from the Department of Chemical Engineering of Chulalongkorn University were awarded the “Gold Medal with the Congratulations of the Jury” for their invention of the “Easily Refuelable Emergency Power Box”.  The exhibition was held between 11-15 April 2018 in Geneva, Switzerland.

 

Associate Professor Soorathep Kheawhom reveals that the idea to invent the power box came up while creating a solution to the limited form of rechargeable batteries.  The refuelable emergency power box uses zinc-air batteries.  Powered by oxidizing zinc and the oxygen in the air, the power box generates energy densities by using zinc metal as fuel.  The power box contains up to 250 grams of zinc and supplies 25 watts of direct current, with a total capacity of 50 watt-hours.  This continual power system greatly reduces battery recharge time and has minimal impact on a battery’s lifespan.
