Patent-pending tech extracts energy from fresh, salt water | University of Hawaiʻi System News
Previous approaches Millions of gallons of freshwater naturally flow into oceans every day. Mixing freshwater and saltwater releases a significant amount of energy, also known as Gibbs free energy. One cubic meter of freshwater flowing into the ocean will release the same amount of energy as one cubic meter of water falling 270 meters. Currently, tapping into this energy source requires specialized and expensive membranes to generate the pressure to drive a turbine, or separate the positive and negative ions in the waters directly. Decades of research and development have shown it is very cha...
