Kerosene lamps used in off-grid, rural areas are a major problem. They’re bad for people’s healthand the environment’s. One startup’s solution is to tap another, greener resource, something we all have in abundance: gravity.
The invention, GravityLight, does exactly what the name suggests: It keeps a light going through the power of gravity. As an attached weight falls, it pulls a cord through the center of the light, powering a dynamo. That dynamo converts the energy from the falling weight into power for the light. (It’s the same idea as a hand-cranked device, just more vertical.) The weight can be set in a few seconds, and as it slowly reaches Earth, enough energy is generated to keep a light working for 30 minutes. As long as it’s set every 30 minutes, it makes for a green, battery-free, continuous stream of light. Other, similar devices like battery chargers could be used through the same process, too.
The inventors say the gadgets can be sold now for less than $10, which would make a return on investment for owners three months after dumping kerosene lighting. And speaking of investments, the group has already shattered the goal for its Indiegogo campaign, meaning we’ll hopefully see these in action soon.
‘It is disingenuous to accuse everyone who calls for restructuring as trying to break up the county. History tells us that that kind of cheap blackmail will not work as long as the underlying reasons for the agitations persist.’
‘The biggest challenge seems to be that we seem to be allowing moderate voices on this issue to be drowned out by the reckless utterances of a few rabble rousers on all sides who may be tools in the hands of those who do not wish this country well. These are some of the people who arrogate to themselves the toga of spokespersons of our diverse groups.’
