8-hour LED illumination with a glass of salt water

Power shortages on many of the islands in the Philippines have prompted an engineer to create 8-hour light bulbs with just one glass of salt water.

Gizmag said on July 26 that Aisa Mijeno , a volunteer engineer and volunteer at Greenpeace, has come up with the idea of making SALt ( Living Light with Sustainable Light) during his stay with the indigenous people. Philippines.

Witnessing the use of oil lamps for their daily activities after dark, Aisa sought to replace the toxic lamps with salty water , the source of abundant raw materials in the Philippines.

The LED SALT operates on a battery pack consisting of two electrodes placed in electrolyte solution saline. This is a common method used in battery design for LED lightbulbs, and is the foundation for providing brighter visibility thanks to renewable energy sources .

Like other batteries, the electrodes can not remain in service forever. The duration of use of the lamp is 8 hours per day within 6 months before replacement of the anode. The finished product will produce enough electricity to charge a smartphone via the USB port on the side of the lamp.

According to the plan, Aisa's company will provide nearly 600 lamps to the Filipino people, while also consuming SALt on the market in early 2016.
