I covered this technique for bringing good light to homes using plastic soda bottles and water awhile back. But the technique has been getting more attention and Priti Ambani of our sister site Ecopreneurist has written about it in more depth, and found a good new video showing how to install the lights and calling for support to help spread the word via MyShelter Foundation Inc.'s “Isang Litrong Liwanag" (or "A Liter of Light") Project. Check out Priti's piece here

Light emitting diodes (LEDs) provide long-life lighting technology that powers flashlights, street signs and medical devices. LEDs have bright output with low input power, making them much more energy efficient than their incandescent predecessors. Hybrid capacitors, a combination of an ultracapacitor and a lithium-ion battery, are an ideal choice for LEDs because the low energy and power of LEDs allows hybrid capacitors to be a longer term energy source than alternative energy storage solutions on the market. Other benefits of LEDs to lighting include little to no required maintenance

You would think, intuitively, that energy efficiency is good — it saves us money and is good for the environment. Some have tried to argue that isn't actually true, that increased efficiency results in greater energy demand and usage. They seem to have confused themselves, though, because that just isn't true
