According to the World Health Organisation, at least 840 million people have no access to reliable electricity. 

This means that 14% of the global population has no light for half of the day!

Two legendary companies have solved this problem by creating the WaterLight, a handheld light that can recharge with ocean water, freshwater mixed with salt, or even urine in emergency situations!

How does it work?!

Once filled with roughly 2 cups, the saltwater electrolytes instantly react with magnesium and copper plates on the inside of the device to generate electricity. *cool, huh?!*

Two cups of water provides 45 days of power depending on usage! Once the salt particles have evaporated the device is simply emptied and re-used! One light can provide 5,600 hours of energy over its lifespan, which is the equivalent of up to three years! It can also be used to charge a mobile phone or other small devices via a USB port!

Why is it important?

This is an efficient solution for remote communities because it regenerates instantly instead of requiring time to convert a source into energy. Saltwater is also a more reliable source than sunlight or wind.

The device can be used for night-fishing, homework, and crafting products. Gosh there are some clever people in this world!
