Adding another invention to our growing water filtration roster, the Trunz Water Systems 200 is definitely one of the top runners. A solar-powered water filtration device, it's a compact box that produces 900 liters of clean, drinkable water in an hour.
The beauty of the Trunz Water Systems 200 is that it requires no fuel and can be converted to become wind-powered as well. It only takes 30 minutes to set up and can run for 24 hours solely on its battery. As Core77 puts it, "It's basically a disaster relief dream come true."
