A prototype designed to test a novel thermodynamic cycle
that generates renewable energy from the evaporation of
water. Power output of the cycle was simulated in Excel,
and a prototype was designed and built using 3d printed
parts, plastic machining, and sensor electronics

Design and Testing

Novel thermodynamic cycle cools air using the evaporation
of water. This temperature difference is then used to
generate useful power. The power output and efficiency of
this system was calculated via simulations in Excel under
differing input conditions. The prototype was made using 3d
printed and acrylic parts, and data was collected and
displayed using temperature, humidity, pressure, and force
sensors.

Impact

Theoretical energy output is ~150w/m^3, rivalling the
output of solar photovoltaics. This system could be used to
generate renewable energy with no inputs besides water
(no purification required) and hot dry air, using cheaply
available materials.
