Endless light using Earth's most abundant resource: Gravity

GravityLight is an affordable, reusable off-grid light source that doesn't require electricity or battery power. Combining kinetic and potential energy, GravityLight works by connecting an elevated weight — filled with rocks or sand — to a pulley system that slowly powers a generator as the weight falls to the ground.

The result of the innovative, kinetic-drive device is free light that can exist virtually anywhere, with no added costs.

GravityLight got its start after a successful Indiegogo campaign in which the startup received enough funding to produce prototypes for 1,300 off-the-grid families. And now, after making tweaks to the original model, GravityLight is ready to release the GravityLight 2.0, to be manufactured in Kenya, where the devices are most in-demand.

In March 2015, GravityLight was named the Shell Springboard Award winner and granted £150,000 to help expand its reach. This support from Shell, coupled with the success of the startup's ongoing crowd-funding effort, "Made in Africa," has ensured that the company's second market foray in 2016 will be a success.

“The funding has really helped us scale up our operation, providing us with the resources needed to explore GravityLight’s place in the wider humanitarian and relief markets," says GravityLight Commercial Director, Caroline Angus.

Shell hasn't been the only one to recognise GravityLight, either. In 2013, Bill Gates took to Twitter and called the device, "a pretty cool innovation."

With increased funding and the public's attention, the London-based shop is looking to expand the product's reach and applications — attempting to position GravityLight as a disaster relief tool — and also hopes to create a GravityLight-inspired radio.
