Water water everywhere...now a drop to drink

Dean Kamen has introduced a truly amazing new device that purifies ANY water.
The claims he makes are truly astounding, such as the ability to get water from the ocean, from poisoned wells, from urine...he claims this device has the potential to eliminate 50% of the diseases the world faces by bringing clean drinking water to the 20% of people of this planet who do not have it. If this thing pans out....WOW.
