Ocean Thermal Energy Conversion (OTEC) process and an ideal location in Puerto rico
Duration : 0:3:51
There is no OTEC …
There is no OTEC plant operating anywhere. However, it is now getting a lot of attention including articles in the New York Times and Worldwatch magazine as well as a morning session at the Offshore Technology Conference in Houston on May 7 (last week)
The new governor is …
The new governor is very supportive of renewable energy and has mentioned in his state of the Island, the OTEC project we have proposed for the Southeast part of Puerto Rico.
Feeding the planet, …
Feeding the planet, energy for life
Nutrire il pianeta, energia per la vita
Nourrir la planète, énergie pour la vie.
Greetings from Italy
It sort of makes it …
It sort of makes it sound like there’s one of these plants existing, but there’s not, right? It’s just that this is how it would work if they got the money to do it.
What is the …
What is the position of the new governor of PR?
Cool, just like …
Cool, just like Geothermal.
thanks i really …
thanks i really liked watching this video, very educational!
uh, thanks for …
uh, thanks for showing us this video. I needed it for my Project.
Again, thank you.
You can obtain much …
You can obtain much more information on our web site which is located under my name on youtube.
I am working on a …
I am working on a local science fair and some of my students would like to use this model as a modeling experiment. Can you direct me to any site/journals more technical information? My students (pre-service teachers) could work on a design with their schooll age students neat experiments and who knows, maybe finding a way to to cost cutting of this project.
Tom, I am an …
Tom, I am an istant professor at Cal State, Stanislaus and teach Science Methodology to pre-service school teachers. I am very interested in this concept. When you say that the units are very expensive what do you mean? Can you give me a ballpark figure of the initial investment and subsequent maintenance costs of the plant? Dr. Ramón Vega de Jesús
The problem in the …
The problem in the Mediterranean Sea is that the cold deep ocean water cannot readily enter due to the shallow depth at the Straight of Gibraltar. This lower depth sill also prevents the cold deep water from entering the Red Sea.
There is work being done in south east India which is close to the cold deep water.
Right now Puerto …
Right now Puerto Rico has the ability to become both energy independent and to create large numbers of good jobs. This is the reality of the current situation. Discussions about past status is too often used as an excuse to do nothing. The current situation calls for actions that are well within the control of the Puerto Rico people.
But even with that, …
But even with that, if you think that now is the time and you are ready to make this work… why don’t you try other places too? Like south Greece where i come from and south Italy. You can find 1000 meters depths at 5 miles range maximum. You know of course that (theoryticly) energy production is allowed for privite sector now. (Practicly is not)
I’ve checked your …
I’ve checked your site. Interesting but it seems to me that this project is allways on the edge. The success of it depends on other things (oil price, technology problems, limited locations, cost).
I have been …
I have been interested in the deep ocean resource since the early 1970s when I helped build a small factory at Cabo Mala Pascua at km 111.0 on Rt. 3. I was unable to get Puerto Rico to become the location for OTEC energy research even when offered the free use of our large unused factory site. With the internet it becomes possible to learn about most of the research and contact the people who were involved in the past and now. Check out our web site for more information.
That is intresting …
That is intresting statistics. How do you have all this information mr. Tom?
High voltage …
High voltage electric cables can exceed 100 miles in length, permitting much of the USA, Mexico, part of India, Africa and even Arabia to connect directly to OTEC plants. Further out locations can be used to generate high energy products such as ammonia in OTEC plant ships.
Most of the tropics …
Most of the tropics between 20 degrees North to 20 degrees South have sufficiently warm surface water to generate electricity year round. More in the summer when more electricity is needed and less in the winter when demand is also lower (due mostly to less air conditioning needed).
About one third of …
About one third of the gross energy is used to pump the water needed to generate the total amount of electricity. The Gross output of a 100 megawatt plant is approximately 135 MW.
It has been …
It has been estimated that OTEC could supply up to 30% of the world’s energy needs. Over 90 locations are close enough to land for direct cable connection including the entire surroundings of the Gulf of Mexico.
This idea is good …
This idea is good as a back up plan to others more well known power production methods. Only in few places can be done so it can’t solve earths problem for energy…
And what about the …
And what about the cooling propane system. Pump all this water from 3000 feet needs a lot of power. That means the energy % will be redused even more. Maybe smaller % from methods like solar or wind. It won’t worth the risk to invest to a tecnology which is at baby stage.
That means big …
That means big energy lost from the distance to bring it home. And what about the winter time? Maybe the climate is pleasant for the tourists but the stream doesn’t work like this. Cold water at the surfice and even colder deeper. So, the plant probably will work half a year…
Maybe that area at …
Maybe that area at PR is ideal for this kind of plant but at how many places in the world you can find 3000 feet depth in a 2 miles range from the coast? No more than 4-5 places. To find 3000 feet depth you need to go 40-50 miles out to the sea, maybe more….
