The winner of the Water Liberation Prize of up to $50,000 will be the
first person to invent a device that is either solar powered, manually
cranked, or otherwise not dependent on the existence of an electrical
grid, can produce at least 4 liters of potable (drinkable) water per
day, either condensed from the air (as measured in approximate 50%
ambient humidity) or filtered through a nanomembrane, and can be mass-
produced (as demonstrated by a pilot run of no less than 100 units)
for a cost of less than $5 per unit. The filter should be washable and
re-usable, without requiring a periodic supply of new filters, as the
device may be used in areas without access to a suitable distribution
channel.
