August 6, 2006 When disasters happen, be they natural (hurricanes, tsunamis, earthquakes etc) or man-made (war), three essentials top the list of must-haves: water, electricity and refrigeration. Now two University of Florida engineers have created a single unit that can provide all three. With further development, it is expected that the unit will be made compact enough to fit onto a large truck. The system marries a gas turbine power plant to a heat-operated refrigeration system. The refrigeration makes the gas turbine more efficient, while also producing cool air and potable water. The turbine can run on conventional fossil fuels, biomass-produced fuels or hydrogen.
