This video starts with a visual montage of
the sheer number of air conditioners used on
our street in Cairo, Egypt, describing them
as energy parasites that actually increase
the heat of the surrounding air. It then
shows the vacuum tube heat pipe solar
absorption cooling air conditioning system
installed by solar engineer Les Hamasaki at
the Debs Park Audubon Environmental Center in
Los Angeles. Les Hamasaki describes the
10-ton solar chiller and we conclude with a
note about how solar chillers not only
eliminate the need for air conditioners, but
the need for entire power plants. They also
produce hot water and can be used for
sterilizing and desalinating contaminated
water. As we say in the video, solar air
conditioners "USE THE SUN'S LIGHT TO DEFEAT
THE SUN'S HEAT!" Thus, the hotter it gets
outside, the cooler it gets inside! Tags :SolarairconditioneradsorptionabsorptionchillervaccuumtubeheatpipeAudubonEnvironmentalScienceCenterDebs
