Alternative Energy Sources

A recent analysis of worldwide wind energy by UNC and Harvard researchers indicates that geophysical and climate considerations reduce the amount  of energy available for harvest from the wind to well below prior estimates....More

Using principles analogous to those of hydroelectric dams, wind catchers from SheerWind could generate power much less expensively than conventional wind turbines....More

MIT researchers have figured a way to move piezoelectric material with polymers that react to water vapor. The technique harvests enough energy from water vapor to do useful work....More

Engineers at the U.S. Naval Research Laboratory are developing a way to turn seawater into fuel....More
