An Indian street vendor gets a light bulb going



Urjar is a device that turns old lithium-ion battery packs into rechargeable energy sources for low-power devices like LED light bulbs, fans and cellphones.

The gadget is created by extracting the lithium-ion cells from a trashed battery and combining them with both charging dongles and safety circuitry.

Roughly 70% of all discarded batteries can provide atleast 4 hours of LED lighting everyday for a year.

It offers extra safety to homes in areas with little to no reliability electricity.
