New UV Technology (September 28, 2011)
This new water purification method sterilizes water using UV radiation. The UV radiation is used to inactivate waterborne water pathogens. The sunlight is captured by a parabolic reflector which is then focused onto a UV pipe that has water running through it continuously. This breakthrough in technology can solve the worlds percentage of water shortage.
