Sea Water powered lamp

Permalink of this case: https://www.futuresdiamond.com/casi2020/casipedia/cases/14444

Colombian renewable energy start-up E-Dina has developed a cordless light that converts salt water into electricity as a more reliable alternative to solar lamps in off-grid communities.The portable device, called WaterLight, needs to be filled with 500 millilitres of seawater or urine in emergency situations to emit up to 45 days of light. It also acts as a mini power generator, the device can also be used to charge a mobile phone or another small device via its integrated USB port. the sustainable innovation being a sea water powder lamp that can power up to 45 days.
