In areas where there is no general electricity supply such as sub-Saharan Africa families spend 20-30% of their income on kerosene to produce light. More than a billion people are concerned.

The development of GravityLight allows to produce light in a cheap and clean way by pulling up a weight of 10kg which produces light for around 20 minutes.
