There are 1.5 BILLION people around the world who live without Electricity...
The rest of us live in a world where the technology we have available to us is absolutely mind blowing. Now a researcher has come up with a very simple idea that will provide "solar" powered lights at 25% of the cost of what they're now paying for non-electrical powered lighting...
Using sheets of Photovoltaic cells (something that's not "new" but because of that - it's not very expensive) Frederick Krebs, a Dutch Researcher is the first person to embed the sheets with LED's - which when they're rolled up, produce light comparable to a lamp (see picture...)
The lights charge up, run all night and last for a year. He's been able to bring the cost of each lamp down from $27 to $7 and he's working on ways to drop that even lower... (which is important when you're trying to help solve the problems of people who are already living in poverty...)
