India's design firm 'D.Light Design' has won an Ashden Award for its solar lamp, which is cited as the world's most affordable solar lantern. What's more, this technology is four times brighter than the average kerosene lamp. D.Light Design's solar lamp is also a cleaner option to kerosene, which produces indoor air pollution that can damage human health.
The potential in these new lamps is incredible. One of the entrepreneurs in the Ashden Award announcement said that "this will do to kerosene what mobile phones did to letters.”
