Osmotic power–the energy generated when freshwater and saltwater mix–is being explored by Statkraft, a Scandinavian company, with the opening of a prototype power plant outside of Oslo.
A group of researchers from City College of New York says that small-scale piezoelectric devices mounted to autos and planes may offer a way to scavenge kinetic energy to power control panels and mobile phones.
Cell towers in southern California will soon serve as a testing ground for small mounted wind turbines which not only power the towers, but also potentially put energy back into the grid.
