gravity powered lighting for developing countries

‘gravitylight’ – gravity powered lighting for developing countries



london based designers martin riddiford and jim reeves have developed the ‘gravitylight’, an innovative new approach to storing energy and creating illumination. taking only three seconds to lift the weight which powers the device, the process creates 30 minutes of light through its descent. the project aims to reach developing countries without access to electricity, where traditionally, kerosene lamps are used for providing luminosity. conceived without batteries, the system works by creating a charge through a ballast that weighs down a pulley, generating the needed energy for power. additionally, the ‘gravitylight’ incorporates an external negative and positive terminals for charging accessories, or batteries if needed.


the ‘gravitylight’ is currently seeking funding on indiegogo.

  • Well the idea of a light powered by gravity is around probably since generators were invented. there are also numerous modern examples. The most beautiful executed one is probably ‘first light’ from ‘post fossil’ that won the price at salone satellite some years ago. Of course packaging old technology in a new design is done all the time, but I do not really know if it is that successful here.

  • First question to be asked if its aimed at the third world, what will it cost.
    Second question. The wind-up torches work so well, when will be the same apparatus/mechanics be applied to wall/table lamps?

    Henk Wessels says:
  • cool ! Don’t like the design so much but the concept is ingenious .

    Thijs Roumen says:
  • Everything is very open with a really clear explanation of the challenges.
    It was truly informative. Your site is useful.
