Energy
The Ocean Thermal Energy Conversion (OTEC) is one method of applying naturally existing sources of energy for generation of energy. It is a system that uses a heat engine for generating electricity. This project makes use of the difference between the temperature of the warm surface water of a tropical ocean (about 25o C) and the cold seawater at the ocean bottom, one thousand meters below (about 5o C). A pipe was installed in a closed loop between the ocean surface and its bottom filled with ammonia. Since ammonia boils at the surface level its vapor drives a turbine generator, which produces electricity. The temperature difference (about 20o C) turns the ammonia vapor into a liquid (a condenser aids this process). The fluid ammonia is then pumped back to the boiler at the surface level. The efficiency of this plant has been small (3-4 %). A great part of its output must go to run the pump. The salt water causes corrosion of the plant’s part. The OTEC plants have been considered useful for island nations. Convert temperatures using the formula for going from C to F is:
F = (C x 9/5) + 32
And to go from F to C:
C = (F - 32) x 5/9.
Several forces are present when ammonia is pushed by the water and converts temperatures.
The OTEC system installed in the tropical ocean between the corral reef at the bottom of the ocean and the surface of the ocean is depicted. This composition focuses on an overall feel of dynamics and action rather than representation of separate objects. The water habitats are shown as ocean life with animals and plants living at different depths, but not too easily spotted. It is a three-part scene: actions and events on the skies above the ocean comprise the atmospheric, animal and human-based actions – clouds carried by the wind, storms with thunder and lightning, heavy rain or hail, but also flocks of birds, planes, gliders, balloons with gondolas, and kites. The surface of the ocean on the horizon line where water meets the sky is populated with all sorts of ships, boats, birds, animals, and sport related actions: sailboats and surfers. A hidden treasure region includes whatever you may think about the underwater life: from plants and living creatures, to sunken galleons, treasures and corral reefs. Thus a cross section of the ocean shows the ocean life coexisting with the man-made constructions set underwater in order to produce energy. A depth related information is shown through the scale. All sorts of creatures live along the pipes, the generator, and objects installed around the system
