Abstract

A method of transferring water provides potential energy with the air pressure of compressed air and uses compressed air used for transfer repeatedly and continuously. The compressed air is retained at the place where the water is transferred from. The compressed air retained is drawn and compressed by a compressor for another transfer operation, and the water is transferred continuously by an alternate replacement between the compressed air and the water. The water can be brought into a place by water pressure where the compressed air acts on the water.

Claims

1. A method of transferring water, comprising:

a. providing two pressure tanks having the same volume installed in water, each said pressure tank having an anti-reflux valve allowing the water to flow into said tank when the pressure in said tank is lower than the water pressure;

b. providing a water tank and an air compressor on the ground, both said pressure tanks having pipes and valves connecting said pressure tanks to said water tank and said air compressor;

c. providing compressed air in one said pressure tank and water in the other said pressure tank;

d. using said compressor to incorporate the compressed air from said pressure tank having the compressed air therein into said pressure tank having water therein so that the compressed air replaces the water and transfers the water to said water tank on the ground;

e. retaining the compressed air in said pressure tank from which the water was transferred;

f. allowing water to flow into said pressure tank from which the compressed air was incorporated in step d through said anti-reflux valve; and

g. repeating steps d-f at least once such that the compressed air cyclically and continuously replaces the water in said pressure tanks and continuously and repeatedly transfers the water in said pressure tanks to said water tank on the ground.

2. The method of claim 1, wherein step d includes adding pressure with said air compressor to the compressed air being incorporated into said pressure tank having water therein to complete transfer of the water to said water tank on the ground.

3. The method of claim 1, wherein step f occurs substantially at the same time as step d.
