The Philippines is a country composed of more than 7,000 islands. It is very vulnerable to natural disasters, such as typhoons, tsunamis, earthquakes, etc. In many places, even electricity is not available. An engineer led a team to develop a portable "seawater-powered light" for this country rich in seawater resources. Pour in a cup of seawater and it will continue to light up for 8 hours. It has a USB charging port that can be used as a charger to charge your phone. The entire process of the chemical reaction of seawater inside the lamp to power the lamp does not produce any harmful substances. Calculated by lighting it for 8 hours a day, the lifespan can be as long as half a year to a year. During this period, no consumables are needed as long as seawater is available.
