The Filipina civil engineer developed the salt lamp with her brother Ralph and electrical engineer Oscar Bryan Magtibay after witnessing the hardships of a Kalinga tribe who’ve had to travel in the mountain for six hours a day just to buy kerosene for their lamps.
Using the principle of electrochemistry, the salt lamp uses the electricity produced by two different elements submerged in a salt-water solution. If used 8 hours a day, the lamp can provide light for up to six months without having to replace parts.
