In 2010, a female Chinese innovator named Daizi Zheng proposed a new approach to powering everyday mobile phones: sugary carbs like Coca-Cola.
Zheng's research found that conventional batteries are expensive and detrimental to the environment because of their difficulty to dispose of and Earth-unfriendly composition. Furthermore, she found that the manufacturing process was resource-hungry and time-consuming.
The alternative she proposes, a bio-battery-powered phone, is biodegradeable and has a potential life-span that is three to four times longer than the commonly-used lilthium batteries.
The bio-battery is powered by the enzymes from carbohydrates - currently sugar - which is poured in liquid form into the top of the 'green phone' that has a removable screw-cap top.
The bio-battery even runs off of Coca-Cola. Once the battery dies, all that remains is oxygen and water.
