Developing the world's 'hottest' heat pump

The heat pumps we use to heat our homes and domestic water operate at temperatures of between 30 and 60 degrees, but many industrial processes require much higher temperatures—and some industries require an entirely different ...

Solar-powered desalination unit shows great promise

Despite the vast amount of water on Earth, most of it is nonpotable seawater. Freshwater accounts for only about 2.5% of the total, so much of the world experiences serious water shortages.
