The Namib Desert in Africa is one of the driest places on earth.With half an inch of rain falling every year,humans call barely survive there for a week with no water.But the Namib beetle does just fine.It collects morning dew that condenses on its back. Inspired by this little creature,27--year--old Edward Linacre,a former student from Swinburne University of Technology in Melbourne,Australia,has designed a new"Airdrop" irrigation system which can pull water from even the driest desert air.His invention won the 2011 James Dyson Award,an international design award.Hopes are high that the system will be able to solve the problems of growing plants on dry land,according to the may Mail.  Linacre studied the Namib beetle and found that it had hydrophilic   skin on its back,which helped catch water molecules passing in the air.These water molecules accumulated into small drops of liquid water.He realized that as long as the air temperature was low enough,even the driest air contains water molecules that can be extracted  . Following this principle,he designed the new system which works by pumping air through a network of underground pipes to cool it to the point at which water condenses.The water is then delivered directly to the roots of plants. According to the research,about 11.5 milliliters of water could be collected from every cubic meter of air in the driest desert.Further development could raise that number even higher . The idea of getting water from the air is not new.However,the Airdrop has certain advantages compared with its competitors.Similar systems often require great amounts of energy because they use refrigeration equipment to lower the temperature.But Airdrop simply uses the temperature difference between the air and the cool earth underground Which of the following is true of the new invention?
It uses refrigeration equipment. It need not to be improved further. It's likely to solve lack of water on dry land. Its underground pipes don't function.
