This is further information on a previous post “How To Power a Seaste Island” and another image I was unable to upload on the first post.
To reiterate, this is basically a wind turbine with its axis in the vertical, contained by a cylinder, with ambient wind diverted into the top of that cylinder and through a heat exchanger. The heat exchanger cools the air with cold ocean water pumped from the depths of the ocean. The cool air sinks, gaining momentum before passing through the turbine at the bottom of the cylinder.
There are several advantages:
Bird deaths eliminated.
The sound of the turbine is mitigated by its containment wall.
Flickering shadows on the surrounding landscape are eliminated.
Maintains a cool environment for heat-generating, rotating turbine/generator parts no matter the external temperature.
The vertical rotating axis of the turbine eliminates gravity and wind-load fluctuations seen by ordinary turbines, making blade construction cheaper.
Seawater in contact with the inner, hard-to-clean surfaces of the heat exchanger is too cold and salty to form algae, minimizing maintenance.
No chemicals to leak into the environment like in some OTEC.
Produces power when wind is still due to the reverse stack effect.
Brings to the surface nutrient-rich deep ocean water to use for aquatic farming.
No azimuth yaw mechanisms needed to keep wind turbine aligned.
Wind energy is forced through the turbine blade and not allowed to bypass around the blade tips.
There’s plenty of “fuel” since 90% of the ocean’s volume is between 32 and 46 degrees Fahrenheit and 40% of the world is tropical or subtropical.
Here is a link to a blog that more fully explains the device and how it works, including more images.
Here is that image I promised. This is the application that is salient to this site. My rendering is limited to cartoons in Autocad but I hope you get the gist.
