Peak Energy: New Funding For OTEC Research

Fri, 10 Oct 2008 20:02:16 -0000

The world’s oceans are an energetic place, and military-industrial giant Lockheed Martin said today it has been granted $1.2 million by the Department of Energy to demonstrate that ocean thermal energy conversion is possible. Although the ocean often doesn’t feel very warm, the temperature gradient between the warm, sun-soaked surface and the frigid, dark depths provides enough of a differential to run a heat engine. The idea has been kicking around for over a century but has never been scaled. Lockheed Martin helped build the largest ocean thermal energy conversion system to date back in the 80s, but it only ever produced 50,000 watts, or .05 megawatts.

Rubber 'snake' could help wave power get a bite of the energy market

Fri, 04 Jul 2008 07:04:57 -0000

Innovative concept could make wave energy more affordable

A device consisting of a giant rubber tube may hold the key to producing affordable electricity from the energy in sea waves.

Invented in the UK, the 'Anaconda' is a totally innovative wave energy concept. Its ultra-simple design means it would be cheap to manufacture and maintain, enabling it to produce clean electricity at lower cost than other types of wave energy converter. Cost has been a key barrier to deployment of such converters to date.

Watertown Daily Times | Alliance details plans for river turbines

Fri, 09 May 2008 08:37:11 -0000

OGDENSBURG — Alliance Energy is proposing to generate up to 110 megawatts of electricity using underwater currents from the St. Lawrence River.

The company proposes to place up to 11 arrays, with each array using 10 underwater turbines, in the river. Each turbine can generate up to one megawatt of electricity.
