I love this stuff. - simon Fri, 23 Nov 2007 06:40:04 +0100 http://www.ecogeek.org/efficiency/1139#comment-7363 This is an interesting idea, but to be a good efficient design, you need more than a serial resistor to connect to the battery. This "standard" design, will loose almost half the battery power over the resistor, something that is very precious in areas with low access to electricity. A small design like the ones using the following device: Will increase the battery life by a minimum of 40%. I am working on a design to make it available for public to drive multiple white LEDs from a cell phone battery, I will send it here when it is done.

I am going to live there in January and, due to severe floods in September, there is a large area being rebuilt. I would happily agree to write/video a review of the lights. Please email me for more information, or with a contact of somebody who would be able to make this decision. Thank you!

It's always good to see cutting edge ideas applied to the world's poorest people. - makewealthhistory Thu, 15 Nov 2007 01:38:54 +0100 http://www.ecogeek.org/efficiency/1139#comment-7176 This is awesome!! new LED lighting solutions are always great! - PT Wed, 14 Nov 2007 21:42:41 +0100 http://www.ecogeek.org/efficiency/1139#comment-7171 The Joule Thief is all about running high-voltage LEDs on low-voltage sources. Step-up transformers, such as flyback transformers, waste some energy in order to put out a higher-quality energy source, in much the same way that heat engines do. A pulsed power source may be an improvement, but the lithium-ion batteries in this light are perfectly capable of providing the 3V that high-efficiency LEDs require. It's probably better just to use the voltage that's already available, and compress the current into quick bursts. It may even be possible to do so using the circuitry of the charger itself, if they're clever enough. - Joel Wed, 14 Nov 2007 21:30:20 +0100 http://www.ecogeek.org/efficiency/1139#comment-7158 Evidently, you don't allow embedded video so here's the youtube URL http://www.youtube.com/watch?v=m56Lu2o9Wfc - gmoke Wed, 14 Nov 2007 13:50:39 +0100 http://www.ecogeek.org/efficiency/1139#comment-7155 Combine this with a previous Ecogeek entry, the Joule Thief, and you've really got something. There's also the Bogolight, an LED flashlight/reading light that charges AA batteries. You pay $25 and they send a second to the developing world. See http://www.bogolight.com for further details. And you might want to take a look at my own concept of the Minimal Solar Light - gmoke Wed, 14 Nov 2007 12:30:06 +0100
