A Clever Lamp That Requires No Batteries, Outlets, or Sun

Abouta billion people exist without electricity , and they often rick to kerosene lamps : ultra severe , carcinogen - spouting , clear flames that could turn homes into tinderboxes . So a new Indiegogo campaign ’s out to provide safe , reusable lights that ask zero outdoor energy source .

It ’s calledGravityLight , and it ’s kind of like those hand crank - power camp lanterns you see at Bed Bath & Beyond , but rather of 10 minutes of manual cranking , the light is power by gravity .

It look kind of like a block fall from the cap . You lift a 25 - pound weight ( rocks , sand , whatever ) by pulling down on a beaded electric cord . After the weight has reach the top and you let go , it slowly descends , powering a drive cog and gear train that get off an LED . Once the bag hits the floor , you repeat the process . The light hold out 20 to 30 minutes each cycle .

On top of being fumingdeath traps , kerosene lamps are a cash suck : The GravityLight team say they can ingest up to 30 percent of a sept ’s income . GravityLight , on the other hand , costs less than 10 buck . The campaign is specifically targeting families in developing country who do n’t have access to electrical energy , with special attention to Kenya , where they hope the intersection can create jobs for people who can manufacture and sell the lights .

The Indiegogo campaign ’s completion in on about half of its $ 199,000 finish and has a month to go . This current labor is actually for the second edition of the ignitor . Last yr , the squad got a tribulation slew of the lamp funded , which was tested in intimately 30 countries . This metre around , the light is brighter , easier to utilize , longer lasting , and stays get off while being charged .

gravitational attraction for estimable is a force we can get behind .
