Effective Renewable Energy System – Ocean Thermal Power Plants!
Renewable energy systems include ocean thermal power plants, in the form of Ocean Thermal Energy Conversion technology, also called OTEC for short. This technology represents enormous potential. The surface of the ocean catches sunlight, and as the water gets deeper it gets colder. The temperature difference between the cold water and the warm water is what creates the energy when it is done properly, but the water temperatures must be at least thirty eight degrees different for the process to be successful. Hawaii has been using OTEC technology for a while, with good results, but as of right now there are few ocean thermal power plants in operation, and these are too small to be really effective. Bigger thermal power plants need to be built, so that they are more effective and cost efficient. These power plants also produce fresh water from salt water as a byproduct of the ocean thermal energy conversion process.
There are three main types of systems used for OTEC, the closed system, the open system, and the hybrid system. In an open system, water is taken in from the ocean, goes through the Ocean Thermal Energy Conversion process, and is discharged back out into the ocean. This means a constant supply of water moving in and out of the thermal power plants. With a closed OTEC system, the loop is closed and water is not discharged into the ocean, but rather continuously cycles through the thermal power plants. Hybrid Ocean Thermal Energy Conversion thermal power plants use aspects from both closed system and open system processes and designs. This allows for greater flexibility.

Hi there, just wanted to leave a quick comment about the interface of your blog. It is really easy on the eye while also being catchy. I think I will do something similar for my blog as well. Thanks for the nice blog share.August 17th, 2010 at 5:43 am
Now and then I’ll stumble across a post like this and I’ll recall that there really are still interesting pages on the web. ^_^. Thanks.August 17th, 2010 at 4:38 am
This should serve as being a clear illustration in the have to have for new vigour sources. If we weren’t reliant on oil, then we wouldn’t have destroyed the ecology within the gulf.August 6th, 2010 at 8:45 am
This definitely sounds like a good renewable energy source, but if the plants change the salinity of the water around them, would that hamper how the plant produces energy?February 20th, 2009 at 11:08 am
Otec plants of course will eventually become the worlds first really sustainable source for the worlds much needed power however it must be noted that this kind of technology is very new and hasnt been researched upon because methinks that this kind of technology will definetely have an effect on aqualife just better and good to tread softlyFebruary 20th, 2009 at 2:52 am
