WebSalinity Gradient (or Osmotic) Power is a renewable energy concept first proposed in the 1950s that has experienced a marked surge of interest over the past decade due to increased availability and improved performance of system components. In physics, chemistry and biology, a potential gradient is the local rate of change of the potential with respect to displacement, i.e. spatial derivative, or gradient. This quantity frequently occurs in equations of physical processes because it leads to some form of flux.
