For many families in third world countries, when the sun goes down at the end of the day, that’s the end of the light. Anything else that needs to be done that day is either going to be done in the dark, or by expensive kerosene lanterns and candles. The money that it takes to pay for these light sources can become a large burden for families who don’t make more than a few dollars per day. Hopefully, this will no longer be the case. A group of engineers from the UK has successfully used Indiegogo to fund their newest project: the GravityLight. The GravityLight is a new type of lamp that uses the potential energy of a 20lb weight to provide between 20-30 minutes of light at a time. The best part is the light only costs around $10 per unit to make, which is HUGE for those that have so little disposable income in the first place. The potential of such a device cannot be understated as it represents so many new possibilities for those who live so far below the worldwide poverty line. They are currently seeking funding for a new longer-lasting light on Indiegogo, with a goal of raising $199,000. Here’s hoping they are able to raise the funds!
