A promising new field of clean, alternative energy lies in the oceans and rivers. Capturing energy from waves and tides is no longer fantasy but gaining much attention; even power companies are investing in the field.
"The industry is still in its infancy, but it is gaining attention, much because of the persistence of marine energy inventors, like Dean R. Corren, who have doggedly lugged their wave and tidal prototypes around the world."
"Moreover, it is not just oceans that could be tapped; the regular flow of tides in bodies of water linked to oceans, like the East River, hold promise too."
"These days, wave power designs vary from machines that look like corks bobbing in the ocean to devices that resemble snakes pointing into waves. There are shoreline machines that cling, like limpets, to rocks.
Tidal power machines, in contrast, often come in the form of turbines, which look like underwater windmills, and generate energy by spinning as tides move in and out; some inventors also are testing concrete-and-steel machines that lie on the seabed and pipe pressurized water back to the shore."
"Even big commercial power companies are joining the action. General Electric; Norsk Hydro, a Norwegian company; and the Germany power giant Eon have recently pledged money for new projects or investments in tiny marine energy companies."
However, just as wind mills can harm birds, so too can tidal turbines harm fish populations, and environmentalists are watching.
“The situation is very similar to wind 15 years ago,†said John W. Griffiths, a former British gas executive and founder of JWG Consulting, which advises on renewable energy projects. He added: “We think that this is an industry waiting to happen".
