British industrial designer Martin Riddiford has created a pineapple-size lamp powered by a 25-pound weight that falls about six feet in a half-hour. That may not sound like much, but it’s enough to drive a silent motor at thousands of rotations per minute. The GravityLight, which shines slightly brighter than most kerosene lamps, requires a certain amount of elbow grease: Once the weight reaches bottom, it must be manually lifted to repeat the process.

This idea convinced the [next idea] jury and the project GravityLight got awarded a honorary mention. We congratulate and dedicate this blog entry to that brilliant project! Ars Electronica [The Next Idea]
Over time the designers say that eliminating the need for kerosene -- which can absorb 10 to 20 percent of a household's income -- has the potential to lift people out of poverty, as well as help prevent illness and injuries associated with traditional lamps. Wired UK
When @BillGates (15.9million followers) tweets your company to congratulate you on something “pretty cool”, it’s safe to say you’re on the right track. To that end, let us introduce you to the engineering duo behind GravityLight- a $10 LED lantern powered by gravity. Shortlist
