“An LED light that runs on rope pulls and gravity has been developed, which could be good news for developing countries without access to stable lighting. GravityLight, a crowdfunding campaign and product created by British designers Martin Riddiford and Jim Reeves, allows a cheap LED kit to run for up to thirty minutes — for free — through no more than a three-second pull on a rope. The energy source after this? Something free that everyone has access to — gravity.”
