# Saltwater-Powered Lamps The SALt Lamp Burns For Eight Hours On Just Water and Salt By Rahul Kalvapalle | Published 2015-07-27 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/salt-lamp References: [gizmag](http://www.gizmag.com/salt-sustainable-alternative-lighting-lamp-saltwater/38626/) & [salt.ph](http://www.salt.ph/) The SALt lamp -- short for 'Sustainable Alternative Lighting' lamp -- is an incredible contraption that is capable of burning for up to eight hours at a time whilst powered by little more than [a glass of water](https://www.trendhunter.com/trends/planto) and a couple of tablespoons of salt. The lamp relies on a galvanic cell battery whose electrolyte solution consists of salty water into which a pair of electrodes are placed. The lamp can be used for eight hours a day for around six months before the anode needs replacing. The lamp can generate enough power to [charge smartphones via its USB port](https://www.trendhunter.com/trends/sodiumfrostglow-flashlight). The SALt lamp was conceived by Greenpeace engineer Aisa Mijeno, who was looking for a way to replace the [dangerous kerosene lamps](https://www.trendhunter.com/trends/fire-capsule-oil-lamp) used by many tribal peoples in the Philippines to perform tasks after dark. This lamp could indeed help bring light to deprived people around the world. ## Trend Insights (Trend Hunter) - Score: 4.7/10 - Popularity: 51% | Activity: 81% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: Asia, Africa ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### Key Themes Behind This Trend - **Saltwater-powered Technology:** Opportunity for developing innovative products and devices that can be powered by saltwater instead of conventional energy sources. - **Sustainable Lighting Solutions:** Opportunity for creating eco-friendly lighting options that utilize alternative energy sources and reduce reliance on traditional electricity. - **Off-grid Power Generation:** Opportunity for developing off-grid power generation systems that are accessible, affordable, and reliable, especially in areas with limited access to electricity infrastructure. ### Where This Applies - **Renewable Energy:** Opportunity for integrating saltwater-powered technology into renewable energy systems, such as solar, wind, and hydroelectric power. - **Emergency and Disaster Preparedness:** Opportunity for incorporating saltwater-powered lamps and devices into emergency kits and disaster relief efforts to provide sustainable lighting solutions during power outages. - **Remote Areas and Developing Countries:** Opportunity for delivering affordable and sustainable lighting solutions to remote areas and developing countries with limited access to electricity. ## Related on Trend Hunter - [Sustainable Light Designs](https://www.trendhunter.com/trends/geolectric-lantern.md) - [Naturally Inspired Digital Candles](https://www.trendhunter.com/trends/magma-lamp.md) - [Glowing Power-Free Lamp Designs](https://www.trendhunter.com/trends/nisshoku.md) - [Sunlight-Mimicking Panelled Lamps](https://www.trendhunter.com/trends/sunne-lamp.md) - [Water Purifier Devices](https://www.trendhunter.com/trends/ladislamp-disinfection.md) - [Subzero Sodium-Ion Battery Flashlights](https://www.trendhunter.com/trends/sodiumfrostglow-flashlight.md) - [Water-Powered Planter Smart Lights](https://www.trendhunter.com/trends/planto.md) - [Portable Tilted Battery-Powered Lamps](https://www.trendhunter.com/trends/lumio-ovo.md) - [Flickering Candle-Inspired Lanterns](https://www.trendhunter.com/trends/nebo-big-poppy.md)
