Abstract
Abstract An installation and a method for the production of energy which utilize a source of heat or natural thermic differences are described. A first container contains a fluid in the liquid state and is capable of transmitting the heat to the fluid, a second container being used for holding the fluid after completion of the thermodynamic cycle and after it has returned to the liquid state, the second container being at a temperature lower than the temperature which prevails in the first container. Conduit means for connecting the first and second container are provided. The fluid has a low boiling point and is capable of undergoing a change from the liquid to gaseous state. A turbine or equivalent device is provided to utilize the kinetic energy of the fluid and transform this energy into mechanical energy; the fluid is converted from the liquid to the gaseous state upon entry into this device and returns to the liquid state in the interior of the second container. The operation may be reversed with the second container being exposed to the source of heat.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
213 words
An installation for the production of energy of the type which utilizes a source of heat or natural thermic differences which comprises two containers of suitable dimensions, the first container containing a fluid in the liquid state and being capable of transmitting the heat to said fluid, the second container being used for holding the fluid after completion of the thermodynamic cycle and after it has returned to the liquid state, a cooling source for cooling said second container, said second container being at a temperature and at a pressure lower than the temperature and the pressure which prevail in said first container, conduit means for connecting said first and second container, said fluid having a boiling point at one atmosphere lower than the minimum temperature of the cooling source in the location of the installation, said fluid being capable of undergoing a change from the liquid to gaseous state, and a device capable of utilizing the kinetic energy of the fluid and transforming said energy into mechanical energy, said device being placed in the conduit means between the first and the second container, said fluid being converted from the liquid to the gaseous state upon entry in said device and returning to the liquid state in the interior of said second container.
Claim 2
Dependent Claim

An installation for the production of energy of the type which utilizes a source of heat or natural thermic differences which comprises two containers of suitable dimensions, the first container containing a fluid in the liquid state and being capable of transmitting the heat to said fluid, the second container being used for holding the fluid after completion of the thermodynamic cycle and after it has returned to the liquid state, a cooling source for cooling said second container, said second container being at a temperature and at a pressure lower than the temperature and the pressure which prevail in said first container, conduit means for connecting said first and second container, said fluid having a boiling point at one atmosphere lower than the minimum temperature of the cooling source in the location of the installation, said fluid being capable of undergoing a change from the liquid to gaseous state, and a device capable of utilizing the kinetic energy of the fluid and transforming said energy into mechanical energy, said device being placed in the conduit means between the first and the second container, said fluid being converted from the liquid to the gaseous state upon entry in said device and returning to the liquid state in the interior of said second container.
Claim 3
Dependent Claim
67 words
The installation according to claim 1 which comprises valve means within said conduit means, said valve means being opened to let the fluid flow from said container into said device where the fluid changes from the liquid state to the gaseous state, and being discharged in the second container which is kept at a lower temperature, said fluid returning to the liquid state in said second container.
Claim 4
Dependent Claim
41 words
The installation according to claim 2 wherein the valve means have adjustable opening so that the flow of fluid within the device which utilizes the kinetic energy of the fluid is maintained constant during the entire work cycle of the fluid.
Claim 5
Dependent Claim
54 words
An installation for the production of energy according to claim 1, which comprises means for reversing the installation at the end of a work cycle whereby the second container is subjected to the action of a source of heat and the first container is brought at the lower temperature at which the cycle occurs.
Claim 6
Dependent Claim
53 words
An installation according to claim 1 wherein a conduit connects said containers, said conduit being provided with a check valve and a pump manipulated by external means whereby the fluid which is in the liquid state in said second container is reintroduced in said first container at the end of a work cycle.
Claim 7
Dependent Claim
46 words
An installation according to claim 1 which comprises a movable shield which is capable of being alternatively placed upon said second or said first container during each work cycle to expose alternatively only said first container or only said second container to the source of heat.
Claim 8
Dependent Claim
149 words
An installation for the production of energy according to claim 1 which comprises two containers, the first of said containers being placed above ground level and being subjected to a source of heat, the second container being placed under the ground level and being provided with an upper movable wall, first and second conduit means between said first and said second container, valve means within said conduits, means for raising said upper wall and for maintaining said upper wall in raised position whereby the fluid in the liquid state which has been transferred from the first container assumes the maximum volume in said second container, means for lowering said upper wall and for decreasing the volume of said second container and for increasing the pressure of the fluid therein, means for opening said valve means in said second conduit means and for reintroducing said fluid into said first container.
Claim 9
Independent Claim
135 words
A method for utilizing a source of heat for the production of energy which comprises heating a low boiling liquid substance in a first zone which is exposed to the action of said source of heat; removing said liquid substance from said first zone and then converting said liquid substance into the gaseous form whereby the kinetic energy of the liquid substance is converted into mechanical energy, transferring said substance in the gaseous form into a second zone which is kept at a lower temperature whereby the substance is converted into the liquid form, said low boiling substance having a boiling point at one atmosphere lower than the minimum temperature in the location in which the source of heat is utilized and continuing the flow of the substance until the end of the work cycle.
Claim 10
Independent Claim
135 words
A method for utilizing a source of heat for the production of energy which comprises heating a low boiling liquid substance in a first zone which is exposed to the action of said source of heat; removing said liquid substance from said first zone and then converting said liquid substance into the gaseous form whereby the kinetic energy of the liquid substance is converted into mechanical energy, transferring said substance in the gaseous form into a second zone which is kept at a lower temperature whereby the substance is converted into the liquid form, said low boiling substance having a boiling point at one atmosphere lower than the minimum temperature in the location in which the source of heat is utilized and continuing the flow of the substance until the end of the work cycle.
Claim 11
Dependent Claim
48 words
The method according to claim 8 wherein the liquid substance in said second zone is exposed to the action of said source of heat, at the end of one work cycle and the cycle is reversed with said substance flowing from said second container to said first container.
