GravityLight - How Does it Really Work?
GravityLight is an innovative light powered by the force of gravity – all you need is a weight.
GravityLight has been designed as a clean, safe and low cost alternative to kerosene lamps, used by over 1.3 billion people without electricity. That’s over 1 in 5 people.
GravityLight covers aspects of design, science and technology, social and economic topics.
GravityLight encompasses:
- the physics of how it works
- the product development process of trials, feedback and iterative improvements
- the challenges of starting up a global organisation
- the potential for GravityLight to reduce CO2 and black carbon emissions
