Coffee Time Challenge Collecting and deploying water in drought-
stricken regions is vital, but far from easy… By 2025, the
United Nations forecasts that 1.8 billion people will be living
in countries or regions with water scarcity and two thirds of
the world's population could be under conditions of water
stress. Climate change is expected to aggravate water problems
via more extreme weather events. For this reason, there is
currently a rush to arrive at any intelligent and improved
management options to overcome these challenges. The need to
retain water in the most apparently dry conditions is therefore
paramount. Even the driest air contains water molecules which
can be extracted by lowering the air's temperature to the point
of condensation. The only question is 'how'? The challenge this
month is therefore to come up with a means of collecting the
water molecules in the air and harnessing them in such a way
that they can be used to irrigate water-starved areas. The
solution is obviously based on the colle
