When there's no electricity, it's pretty difficult to do … anything. Whether you're camping or trying to get through a power outage, you don't want to have to worry about dead batteries in your flashlight or struggling to see by dim candlelight. The Lumir K lamp, now raising money on Indiegogo, provides bright LED light using only a tiny bit of cooking oil.
The Lumir K works with a wick, like a candle, but provides the brightness of an electric lamp, burning 100 times brighter than a traditional candle. To turn it on, users just need to pour cooking oil in the container, light the wick, and place the lamp cover on top of it. To turn it off, users can simply blow out the candle. Roughly 1 teaspoon of oil can provide an hour of light. Unlike solar lamps, Lumir K can provide year-round light even in very rainy environments.
In the developing work access to electricity to charge devices, disposal of batteries, etc are still problems. Often cooking oil is still available or has been used and is anyway not disposed of in an environmentally friendly way. Whilst this still involves some combustion, its overall footprint may be less given the existing context in these countries.
