A winner of the James Dyson Award as well as an Asia Design Prize, the Lumir K is a lamp that uses cooking oil, instead of kerosene, as fuel.

The Lumir K relies on a phenomenon called the Seebeck Effect, where a temperature difference between two dissimilar electrical semiconductors produces a voltage difference between the two substances.
