Default Limitless clean energy on the way? NEW SCIENTIST

Limitless clean energy on the way?

FOR a company whose business is rocket science Lockheed Martin has been paying unusual attention to plumbing of late. The aerospace giant has kept its engineers occupied for the past 12 months poring over designs for what amounts to a very long fibreglass pipe.

It is, of course, no ordinary pipe but an integral part of the technology behind Ocean Thermal Energy Conversion (OTEC), a clean, renewable energy source that has the potential to free many economies from their dependence on oil.

"This has the potential to become the biggest source of renewable energy in the world," says Robert Cohen, who headed the US federal ocean thermal energy programme in the early 1970s.

As the price of fossil fuels soars, private companies from Hawaii to Japan are racing to build commercial OTEC plants. The trick is to exploit the difference in temperature between seawater near the surface and deep down (see diagram).

First, warm surface water heats a fluid with a low boiling point, such as ammonia or a mixture of ammonia and water. When this "working fluid" boils, the resulting gas creates enough pressure to drive a turbine that generates power. The gas is then cooled by passing it through cold water pumped up from the ocean depths via massive fibreglass tubes, perhaps 1000 metres long and 27 metres in diameter, that suck up cold water at a rate of 1000 tonnes per second. While the gas condenses back into a liquid that can be used again, the water is returned to the deep ocean. "It's just like a conventional power plant where you burn a fuel like coal to create steam," says Cohen.

The idea of tapping the ocean's different thermal layers to generate electricity was first proposed in 1881 by French physicist Jacques d'Arsonval but didn't receive much attention until the world oil crises of the 1970s. In 1979, a US government-backed partnership that included Lockheed Martin, lowered a cold water pipe from a barge off Hawaii that was part of an OTEC system generating 50 kilowatts of electricity. Two years later, a Japanese group built a pilot plant off the South Pacific island of Nauru capable of generating 120 kilowatts.

In the first flush of success, the US Department of Energy began planning a 40 megawatt test plant off Hawaii. Then in 1981, the funding for ocean thermal technologies began to dwindle. It dried up altogether in 1995 when the price of oil began to drop, eventually falling below $20 a barrel.

Now rising fuel costs have revived interest in this neglected technology. In September, the Department of Energy awarded its first grant for ocean thermal energy in more than a decade, giving Lockheed Martin $600,000 to develop a new generation of cold water pipes

What pisses me off is that they only gave $600,000 to develop this. This should have millions poured into it! however, that would also mean the Department of Energy would **** off all the oil companys and we cant have that can we. Free, clean energy for the whole world? Far too much to ask when it comes to making a profit.

i had an idea that they would throw us a bone to get us back inline with the eugenics plan.. it would be like showing a phone to a lost amazon tribe.. we would wonder at it like children and then follow blindly into the NWO.. just my thought..
i mean there is hh0 tech. anti grav. the list goes on.. this is just another distraction
