Did you know that a bag of rocks and a downward force could
Light the world?
Creating a future that’s bright and safe for all is at the heart
of gravity light – the lamp
that’s lighting areas of the world with limited access to electricity using the
power of gravity. As the 2015 winner of shell’s springboard programme ,GravityLight is a gravity (there’s that word again) powered lamp
designed by Deciwatt to provide a safer, cleaner alternative to the dangerous
kerosene lamps which are common in the developing world
as of 2015 1.1 billion people are still without access
to energy . For many of these people the only affordable
solution to their lack of access has been kerosene lamps which are harmful to
their health. In fact, studies have shown that inhaling the toxic fumes from
kerosene lamps is the equivalent of smoking 170 cigarettes per year;
unintentional ingestion of kerosene is the leading cause of child poisoning.
in the developing world . Beyond respiratory
issues, the danger these lamps pose to the societies they light are plenty – in
India alone the WHO estimates that one million people each and every
year suffer moderate to severe burns caused by overturned kerosene lamps.
Exploring the great potential of the simple – and
infinite – force of gravity has allowed GravityLight to combat issues of energy
inaccessibility and risk to public health, paving the way towards a safer
future for those that need it most.
The magic of the rocks? As gravity does its thing and
pulls the rocks to earth the force pulls a strap, which in turn spins gears,
driving an electric generator, powering an LED. That’s quite the chain
reaction, but it works – Each journey to ground creates enough energy to give
continuous light for 20 minutes. The device will combat the issue of energy
expense in the developing world – there are no operating costs after an initial
purchase of a GravityLight, and it can last for years.
Following its recent second successful crowdfunding
campaign and with support from Shell, The GravityLight Foundation is on a 50
Night Tour across 50 villages of Kenya. People in these villages
regularly can be found lighting their homes with harmful kerosene lamps. Now
they can see for themselves the innovative solution that the GravityLight can
provide – a reliable source of safer, cleaner energy to the people of Kenya.
