Today technology has advanced to reach sky limits. Newer techniques have been evolved to make our life easy and stress free. One such recent invention is of Greener battery by MIT scientists.
Also as pollution is becoming threat to environment, every new invention is tested whether it is environment friendly or not. A presidium of researchers at MIT has come up nature friendly method to generate electricity that harnesses heat without incorporating metal or toxic materials.
This invention is vital as most of the batteries that power everything from smart phones to computers are made of toxic materials like lithium which can be difficult to dispose off and have restricted global supply. Apart from this lithium is also profusely flammable.
The brain child behind this invention is Michael Strano, the experienced scientist of MIT who found that wire made from tiny cylinders of carbon known as carbon nano tubes can produce an electrical current when it is progressively heated from one end to the other in the same manner as one holds the fuse.
When the pulse of heat pushes the electrons through bundle of carbon nano tubes, the effect is seen as the carbon nano tubes that carry the electrons look like surfers riding the wave. Stran and his team of scientists have gone one step ahead and raised this efficiency more than a thousand fold. In other words they have produced devices that can put out power in sync to that the today’s best batteries generate.
This invention has bought laboratory technology to be within the striking distance of other portable energy technologies like lithium – ion batteries or fuel cells. The device has been experimented on simple electronic devices like LED light which revealed that it is robust enough to power the LED light.
A feather in the cap is that the greener batteries have indefinite shelf life whereas the batteries lose power if they are stored for longer period of time and this makes these batteries beneficial for deep space probe uses where the probe remains dormant for many years as it travels to a distant planet and then requires quick burst of power to send back the data the moment it reaches the desired destination.
Also as per the scientists the newer system of greener batteries is very scalable for use in increasingly tiny wearable devices whereas batteries and fuel cells have certain drawbacks that make them difficult to shrink them to tiny sizes. In fact the scale of these new batteries is unique.
Scientists view this invention as an important demonstration of increasing the energy and lifetime of thermo power based systems and this step makes the technology more applicable for real time applications. This new way of tapping energy by MIT scientists is surely going to give new dimension to all the battery driven appliances.
