Your laptop battery is no more of use. Don’t be too quick to throw it out the battery from the laptop. It might be used for powering homes in developing countries, and helping the environment in the process.
Thanks to IBM researchers who have revealed UrJar, a device that turns old lithium-ion battery packs into rechargeable energy sources for low-power devices like LED light bulbs, fans and cellphones.
How it works?
The team extracted functioning lithium-ion cells from a trashed battery and combined them with both charging dongles and safety circuitry.
Thought it sounds simple, it’s potentially very effective. The company claims that roughly 70 percent of all discarded batteries can provide at least four hours of LED lighting every day for a year.
The power is enough to offer extra safety to homes in areas with little to no reliable electricity, or to keep a street vendor in business after sunset.
The researchers said, some final changes are necessary before UrJar is ready, but IBM is quick to stress that this isn’t a commercial product.
It rather hopes to give devices away for free in countries whose energy poverty hurts the quality of life and chances of a better future for poorer residents.
UrJar should also kill two birds with one stone by making good use by reducing the mountain of the e-waste.
Rather than send your old batteries directly to landfills, you could give them a second life that helps the less fortunate.
That’s not as eco-friendly as truly clean power, but it might prevent technological garbage from getting out of control.
