Imagine not having to buy batteries ever again... Just think about the amount of battery-powered gadgets we use daily in our lives, and the problem it is when we have to throw them away. Simply take a moment to think how much our planet is damaged with this process, and the number of people who use and dispose batteries every day. Under such premise, and to address this problematic, Mexican scientist Arturo Solis Herrera was motivated to start an important research regarding this small and little lasting-power sources, which pollute the planet in large amounts. Bat gen is the name of this ever-lasting battery. It consists of a biochemical process triggered by mixing water and melanin, which results in a substance capable of separating oxygen from hydrogen (the components of a water molecule), therefore liberating energy. The process continues as the same molecule brings together both elements turning them into water again; as a result one more energy load is triggered.
