This report was written by Jerome Johnson and Michael Cropp of the Center for Innovation and Development at the University of Wisconsin. The paper reports on their research into the design and implementation of a water purifier that is powered by solar thermal, which also uses that heat for heating and power purposes.
The researchers design uses parabolic solar troughs which have water pumped through them to use as both a desalinator and purifier. It then captures the excess steam and uses that as steam turbine power. The researchers found that the use of flash evaporation increased the efficiency of their design in comparison to others, and would prove particularly useful in colder climes.
