South Korean scientists have introduced the new MetalCell, a battery that is modeled after a design created 2,000 years ago in Baghdad, now called Baghdad Batteries. The original design used terracotta jars, copper cylinders and an iron rod. When an acidic solution was added it could have generated low-level voltage.
The MetalCell is a unlike other rechargeable batteries in that it is: 1. refuelable 2. takes seconds to recharge. According to a S.E.G. Inc. report, The battery contains either magnesium or aluminum plates. Addition of salt water, creates a chemical reaction and generates electricity. Adding extra salt water will recharge the battery until the magnesium dissipates. The battery can charge anything from flashlights to night vision goggles to laptops. While saltwater creates the preferred chemical reaction, addition of urine can also help charge and power the cells.
These battery cells may not take the place of wind or solar in terms of generating mass amounts of energy, but it begin invading our household. Japan has created urine powered batteries for public use. Currently available in AAA and AA size, these batteries (NoPoPo) produces 500 milliamps/hr and can last up to ten years. Like it’s larger brother, MetalCell, the NoPoPo contains magnesium (and carbon) which reacts with various liquids. Unfortunately the batteries are only available in Japan.
So the next time you’re going to the bathroom, remember that your pee also has its place in saving the environment.
