New style of battery
Battery is widely used everyday to provide power for all kinds of little lighter and big family appliance, but have you ever thought about what we are gonna do with these batteries? we may throw them away or someone gathers them in a certain place. The battery which we throw into outside world will cause great pollution to environment, but some expert will do something to solve this problem.
A new battery-sized portable generator than produces electricity from vibrations could take the place of normal batteries in gadgets. The device could replace the huge numbers of conventional batteries that are currently used in the modern world’s ever-expanding number of portable gadgets and which often end up polluting landfills.
Many standard batteries are thrown out with the normal refuse and end up in landfill sites where they can leak toxic chemicals, causing great harm to the environment. The Vibration Energy Cell batteries recently displayed by a Japanese electronics company could radically reduce the practice of throwing away old batteries, thereby lowering the risk that discarded batteries end up causing more pollution.
Brother Industries, already well-known to many consumers as a producer of printers, says the vibration-harvesting generators could in some applications be substituted for AA or AAA batteries. The company demonstrated the generator power a television remote control, a remote-control light switch and an LED flashlight.
The Vibration Energy Cell works in a manner similar to the dynamo used to power bicycle lights. In this case, shaking the device a few times produces the electrical power. Speaking to the BBC, a spokesman for Brother explained how the device uses a coil, a magnet and a condenser to store the electricity produced from the movement. The Vibration Energy Cell generates low amounts of electrical power and is designed to be used in devices like TV remote controls, which have low power requirements and do not continuous electrical supplies.
