Scientist and inventor, Dean Kamen, is responsible for the innovative efforts at DEKA RESEARCH. This Slingshot Water Purifier system has been expensively floating around for at least 10 years. It is reportedly quite efficient at producing pure water from very impure sources. Once the price can be more affordable, the consequences for water challenged areas of the world will be profound.
“One Slingshot unit can purify up to 300,000 liters of water each year — enough daily drinking water for roughly 300 people — producing 10 gallons of clean water an hour while consuming less than 1 kilowatt of electricity, which is less than the amount of power needed to run a standard handheld hair dryer. The unit can be plugged into the local grid or can be powered by other locally available and renewable power sources such as solar cells, batteries, or another DEKA invention — the Stirling electric generator, which can be powered by biogases such as methane from local waste sources.” (X)
