Fast Company reports on a solar powered lamp developed to help refugees and those in developing nations reliant on kerosene lamps. From the article:
The SolarPuff is a two-ounce, flat-pack solar lamp which quickly expands into a 4.5-inch cube. The lantern can last eight hours and easily recharges with clear sunlight. It provides enough light for refugees or people in impoverished areas to perform tasks at night, without instigating any dangerous fires or needing batteries.
Engadget highlights a potentially huge leap in the efficiency of solar cells (i.e. the amount of sunlight converted to electricity.)
A team of researchers in Australia has achieved a conversion rate of 34.5% – the previous record was 24%. Some had predicted that a 35% efficiency rate would be decades away: hopefully the approach can be quickly applied in the real-world.
Researchers at the University of Exeter (UK) have found that adding green LED lights to fishing nets can significanty reduce that numbers of turtles that get trapped and die, without impact on the quantity of fish caught.
Inhabitat highlights the development of an LED-based alternative to wi-fi, that promises to be 100 time faster and harnesses the imperceptible rapid blinking of LED lights to send data to compatible devices. The system is currently being tested in a few countries, including France and India.
A new Indiegogo campaign aims to bring lighting to some of the 1-billion+ people who don’t have access to safe and clean lighting. The Gravity Light 2 could replace kerosene lamps (responsible for health and environmental issues) in low income and developing nations. The ingenious design using weights and gravity to provide light is nearly half way to its funding goal.
