Abstract
Abstract A hydraulic turbo-generator driven by a water current is used for producing electric power; the water is supplied to the turbine (5) by means of a conduit (4). The high pressure vapor is produced in a vapor generator (2) and combined in the water current, so that the expansion energy of the vapor is transmitted to the water, if possible completely, and to the turbine. The interaction duration of the vapor and the water is considered to be a very short due to the high speed of the water, so that substantially no heat exchange occurs, thereby obtaining a plant output higher than that of conventional plants.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
152 words
An improvement in a process for generating electrical current by means of hydraulic turbogenerators, wherein a conduit connects a water reservoir with turbines of said turbogenerator, said conduit containing a water stream supplying motive power to said turbines, said water stream being subjected to common air pressure conditions at said reservoir, with a vapor generating chamber adjacent the water stream conduit at a point outside of the turbine space and in fluid communication with said water stream conduit, said improvement comprising: inserting the high pressure vapor into said water stream conduit at said point outside of said turbine space into one side of said water stream, said water stream having a very high flow rate in said conduit, such that continuous pressure and velocity increases are caused in said water stream, and that practically no heat exchange takes place between the inserted vapor and the water prior to contact with the turbines.
Claim 2
Dependent Claim
152 words

Claim 3
Dependent Claim
22 words
The improvement as claimed in claim 1, further comprising the step of using high output rotary pumps for generating the water stream.
Claim 4
Dependent Claim
20 words
The improvement as claimed in claim 1, further comprising the step of generating the high pressure vapour in steam generators.
Claim 5
Dependent Claim
29 words
The improvement as claimed in claim 1, further comprising the step of recirculating the water discharged from the turbines, such that the water is circulated in a closed circuit.
Claim 6
Dependent Claim
42 words
The improvement as claimed in claim 1, wherein the water stream has a velocity on the order of 50 meters per second and that said high pressure vapour is inserted at a point on the order of 5 meters upstream the turbines.
