The liquefied working fluid 12 from every two condensers 20 is collected by one thermal-isolated high pressure resistant pipe 90 that drives the falling liquefied working fluid 12 downwards from the condensers 30 back to the evaporator 20, passing through a reaction turbine 51. Each descending pipe 90 is equipped with a group of high pressure resistant valves 910 that divide the pipe in sections, working as flow controllers, that when closed interrupt the flow of the descending column of liquefied working fluid 12 in order to prevent the loose into the environment of said liquefied working fluid 12 in case of an accidental crack or break of the pipe 90. The liquefied working fluid 12 falls as a column of fluid through the pipes because gravity, increasing its density with depth. 2A, 2B, 2C, 2E and 2F. In order to assure an optimal flow of working fluid through the thermodynamic circuit 10, the ascending conduit 40 widens with height in the same proportion as the gasified working fluid 11 loses density (FIGS.

6A, wherein a section of the ascending conduit is depicted, showing the gasified working fluid ascending through the widening ascending conduit, while mixes with the pressuring gas. In the other hand, if a much lighter pressuring gas 41 mixes with said sulfur hexafluoride (the gasified working fluid 11) in the widening ascending conduit 40, and for the same given conditions of gasification and liquefaction described above, said difference in height H2 could be up to 2,500 meters if nitrogen, formulated N2, is used as the pressuring gas 41 (height at which its pressure will be lightly over the needed 15 Bar; FIGS. 11 and a pressuring gas 41 (FIGS. The mode of operation is as follows (please, refer to FIGS. Please refer back to FIG. Please refer again to FIG.

FIG. 6F is a top view of the second embodiment. FIG. Dolor de espalda y falta de respiracion . 11A is a schematic illustration showing a seventh embodiment. FIG. 7A is a schematic illustration showing a third embodiment. 5A, wherein a section of the widening ascending conduit is depicted, showing the gasified working fluid ascending through the said ascending conduit. 2A wherein H1 represents the height between level L0, that is the level at which the liquefied working fluid gasifies with a temperature of T1 at the evaporator unit 20, and level L1 at the top-exit of the widening ascending conduit 40; H2 represent the height between said level L0 and level L2 that is the level at which the gasified working fluid liquefies at the condenser units 30 with a temperature of T0; and H3 represents the height between said level L2 and the level L3 of the power extraction apparatus 50, wherein the liquefied working fluid arrives with a temperature of T0.
In order to correct said losses or increases in heat in the thermal energy conversion plant, the closed-loop thermodynamic circuit will exchange heat with a heat source and a heat sink. 761; at least one auxiliary heating unit 733, in contact with the heat source; at least one pipe that connects the auxiliary heating unit 733 with the evaporator 20 of the closed-loop thermodynamic circuit 10; and at least one pipe that connects the evaporator 20 back with the auxiliary heating unit 733, closing the circuit; wherein the auxiliary heating thermal fluid 721 flows through the auxiliary heating thermal circuit 703 by the action of the pump 761, driving heat 31 from the heat source into the evaporator 20. The auxiliary cooling thermal circuit 704 comprises: an auxiliary cooling thermal fluid 722 (detail V6, depicted in FIG. In a solar plant 320 an external thermal fluid 723 (per example water) is heated by solar radiation 321 through solar panels 322. The warm external thermal fluid 723 is stored in a thermal pool 323 from where flows through an external heating thermal circuit 713, which is connected with the heating unit 73, by the action of a pump 755. The external heating thermal circuit 713 is also connected with a gas fired plant 330, wherein the external thermal fluid 723 gains heat from a burning gas in a gas furnace 331, when its temperature is lower than an optimal value, what could occur, as per example, because a decrease in solar radiation due to seasonal or climatic reasons.
3B and 3F wherein is depicted a second exemplary scheme of operation of the invention, wherein by means of a thermal fluid 71 (detail V4, depicted in FIG. As described, the external fluid drives the waste heat from the aluminum processing plant 310 into the auxiliary heating unit 733 wherein the auxiliary heating thermal fluid heats up (cooling down the external thermal fluid) prior to entering into the evaporators 20.

When using the water of a river as heat sink it would be desirable to do so in very large rivers, with a vast flow, and near its mouth, in order to avoid thermal pollution in its waters. Hitherto constructed Sea Thermal Energy Conversion plants-OTEC had not been able to produce significant amounts of energy, when compare to nuclear or conventional thermal plants. The heating 73 and cooling 74 units of the thermal circuit 70 will be of the type of plate heat exchanger, in which the fluids are exposed to a much larger surface area than in conventional heat exchangers, what improves the transfer of heat.
The dynamic position system, DP 205, under the information obtained from the current meter 204 and the meteorological station 206, will control the exiting flow of sea water through the exits (981, 982), increasing, decreasing or ceasing the flow through each of them, giving to the floating vessel 103 and the submerged vessel 102 of the evaporator 20 motion in one or another direction. Thus, unless expressly stated otherwise, each future disclosed is one example only of a generic series of equivalent or similar features. Also, any other heavy molecular weight gas could be selected as working fluid, as for example the nonflammable and nontoxic Hexafluoroethane, formulated C2F6, also known as R-116, which has a molar mass of 138.02 g/mol.
