The Capsuli is a rechargeable solar powered LED emergency light kit that’s small enough to be stored while powerful enough to emit light from the palm of your hand. As small as it is, this thing is bright. Each capsule docks onto a pad embedded with solar cells. You activate the light by twisting the capsule. It’s just a concept for now so technical specifications aren’t available but the idea is sound. In fact, I think cities should be giving citizens basic emergency supply kits - each one should include something like the Capsuli.
