Lumir: a candle-powered LED light

Lumir, the LED powered by a candle. I can see why this would be useful. It's hard for many people, especially older people, to read by a single candle. But I can also see why people would not understand the concept. I can see them thinking "Why would I use a candle if I could just use my $4 LED flashlight or headlamp?"

That's a valid thought. But the technology in Lumir is pretty neat if a bit impractical for many western nations with power. However for nations without power, this might help them study at night by generating enough light to read by. However Lumir is much more expensive than some of the other solar charged lights for Africa.

There are several variations of Lumir and Lumir Spot would be the best for reading a book or magazine.

This appears to use a thermoelectric generator (TEG) and a voltage booster. But TEGs don't product much power, and the voltage boosters to boost the volts up high enough for an LED are expensive.

Wow! It seems they are $109usd on Amazon now.
