JJR has a post on the BOGO light, a solar flashlight.
A light, simple and well designed flashlight great for rural areas where there isn’t much electricity, plus everyone needs to have a flashlight in case of an emergency.
BoGo means Buy one, Give one. We want our lights to benefit the less fortunate; therefore, with each light purchased in the developed world, a second identical light will be donated to an organization that will distribute it in the developing world with our direct financial support
You can read about the success stories which just warm your heart…
The BOGO light is also available at Whole Foods markets around the US, which is where i first saw it, it costs $19.99.
Nice, but I would love to seem them being assembled in an African country.
I know! JKE. I am not one to encourage patent infringement, but its very tempting to take it apart and reverse engineer it ‘the juakali way’ I receive mine tomorrow, will do a quick test of it!
Talking of lights, check out this article in this week’s EETimes…
EGM, thanks for that link! very interesting indeed…especially towards the end
“The reflective back electrode used in OLEDs causes the device to reflect light constantly, even when turned off, and degrades the contrast when the display is on. The scientists reported that placing a solar cell in the back of the OLED absorbed the incident light and internal OLED emission, and then converted the light to electrical power for reuse as a photovoltaic device. The modest, 0.26 percent power-recycling efficiency of the experimental unit might be improved by using more-efficient OLEDs and solar cells, according to the scientists.”
Very interesting and inventive. Thanks again!!!
