First the sea gave birth to life. Now, thanks to a trio of Philippine-based inventors, it is giving birth to light as well. Led by engineer Lipa Aisa Mijena, the team has developed a lamp that’s capable emitting light for 8 hours on just 1 cup of saltwater. Not only are the Philippines prone to natural disasters like typhoons and earthquakes but the country is made up of over 7,000 islands, most of which do not have access to electricity, says the team. But one thing they do have is the sea, an abundant source of saltwater that can now be used to light homes and, in emergencies, power cell phones.
The saltwater-powered lamp uses the same science that forms the basis of battery-making. Where they differ from batteries is that the entire reaction is safe and harmless. Moreover, there are no flammable materials or components that go into lamp. Used 8 hours a day, every day, the team says the lamp can provide light for 6 months (or even over a year if used more efficiently) without having to replace any parts.
Over the past year or so SALt (Sustainable Alternative Lighting) has won 7 different sustainability and entrepreneurial awards.
