Clean fresh water is scarce throughout much of the world with as many as 2.1 billion people lacking safe drinking water at home. And climate change is adding to the stress. These innovations could help.
Producing drinking water, no power needed
In many parts of the world, the problem isn’t just a shortage of water, it’s that the available water is dirty. Not surprising considering that 80 percent of the sewage in developing countries is discharged untreated. That’s where devices like the SunSpring Hybrid come in. The shiny cylinder houses a self-contained water filtration system that can turn more than 20,000 liters of dirty water into drinking water every day. Perhaps more importantly, it can be set up quickly just about anywhere, as long as there is a water source like a river or a well nearby. Built-in solar panels and an optional wind turbine means it doesn’t need a power supply, which means it could be used in remote regions without access to electricity or places hit by extreme weather events or natural disasters.
