I came across an IndieGogo project that is focused on building and trialing a gravity-powered power station that can serve either as a lantern or as a flexible power source that can be used to power a task light, recharge batteries, or potentially other things that users might dream up that the designers can’t yet imagine.
Check out their video from IndieGogo:
They have already raised FIVE TIMES the money they set out to raise on IndieGogo.
I found it interesting in their promotional video that initially they started with a design challenge of designing a system that would charge a light for indoor use using a solar panel, but that they decided to abandon the approach specified from the outset and pursue alternate power sources.
Also interesting from the IndieGogo project page are the following facts:
The World Bank estimates that, as a result, 780 million women and children inhale smoke which is equivalent to smoking 2 packets of cigarettes every day. 60% of adult, female lung-cancer victims in developing nations are non-smokers. The fumes also cause eye infections and cataracts, but burning kerosene is also more immediately dangerous: 2.5 million people a year, in India alone, suffer severe burns from overturned kerosene lamps. Burning Kerosene also comes with a financial burden: kerosene for lighting ALONE can consume 10 to 20% of a household’s income. This burden traps people in a permanent state of subsistence living, buying cupfuls of fuel for their daily needs, as and when they can.
The burning of Kerosene for lighting also produces 244 million tonnes of Carbon Dioxide annually.
So, what do you think, a meaningful innovation or an interesting but impractical invention?
