The GravityLight Foundation is a UK Registered Charity working to alleviate poverty and protect the environment through innovative design.

Kerosene lamps are widely used for lighting in rural areas where electrical distribution is either not available, or too expensive for widespread use.

GravityLight is an innovative device that generates light from gravity.

In GravityLight, we are aiming to to deliver a product that will have a positive impact for people living without electricity. 

We are conducting trials across both urban and rural households to observe and learn the differences in distribution models, adoption rates and use of GravityLight. We are using a mixture of semi-structured interviews with sales agents and families using GravityLight, in parallel with quantitative data collection through mobile surveys.

We have gained insights on how to tailor our packaging, communications and understanding of under electrified households in Kenya. 

Power is typically generated and stored for later use. What if they removed the power storage - the battery? What if power could be generated as it was needed? They could reduce costs and might be able to gain in efficiency.

We initially developed GravityLight technology to provide a solution to people that currently depend on kerosene for home lighting. However, we quickly came to realise that GravityLight has many potential applications in other contexts. 

Not only did the success of our crowdfunding campaign dramatically change the scale of our intended production run, it also gave us the opportunity to further refine the product before sending samples to off-grid households and crowdfunders to test around the world.
