GravityLight: lighting for developing countries
GravityLight is a new way to help poverty-stricken nations and developing countries. Without a battery to replace or a need for solar charge, the GravityLight only requires a few seconds to lift a weight to provide light for a full half hour. Its LED technology does not attract mosquitos and it has virtually no running costs. To find out how to help the cause, visit GravityLight’s Indiegogo campaign.
