An apparatus for generating electricity using atmospheric pressure and vacuum, comprising:
- a main water tank containing water in communication with the atmosphere;
- a first vacuum chamber positioned at a predetermined height above the main water tank;
- an upward pipeline connecting the main water tank to a bottom side of the first vacuum chamber, wherein the upward pipeline is equipped with a water supply valve at a lower end thereof and has a lower side port adjacently above the water supply valve;
- a second vacuum chamber at a height lower than the first vacuum chamber and higher than the main water tank, wherein a vacuum valve is disposed on at least one of the second vacuum chamber and the first vacuum chamber for drawing air out to create a vacuum therein;
- a first downward pipeline connecting the first vacuum chamber to the second vacuum chamber and having a nozzle fitted at a lower end thereof;
- a power generating assembly disposed within the second vacuum chamber;
- an intermediate water tank adjoined to a lower portion of the second vacuum chamber and in fluid communication with the second vacuum chamber, wherein the intermediate water tank is equipped with a liquid level probe;
- a second downward pipeline having an upper end connected to a bottom side of the intermediate water tank;
- a return pipeline having a first end connected to the lower side port of the upward pipeline through a first normally closed (NC) solenoid valve and a second end connected to a lower end of the second downward pipeline through a second NC solenoid valve, wherein a first normally open (NO) solenoid valve is disposed in a middle portion of the return pipeline;
- and
- an air pressure cylinder vertically connected from above to a middle side port of the return pipeline, wherein the NO solenoid valve is located between the middle side port and the second NC solenoid valve, and the air pressure cylinder includes therein a piston, an extension spring, and a third NC solenoid valve connecting between a space above the piston in the air pressure cylinder and the atmosphere, wherein the extension spring has a lower end attached to the piston and an upper end fixed to a top inner wall of the air pressure cylinder, and when the third NC solenoid valve is open the space above the piston in the air pressure cylinder is in air communication with the atmosphere;
- and
- an overall timer-controller electrically connected via a sub-power switch to the power generating assembly for controlling the operations of the NO solenoid valve and the three (the first, the second and the third) NC solenoid valves,
- wherein when the water supply valve and the vacuum valve are closed, the NO solenoid valve is open, the first and the third NC solenoid valves are closed and the second NC solenoid valve is open, a continuous closed space is formed within the apparatus, which extends from the upward pipeline, through the first vacuum chamber, the first downward pipeline, the second vacuum chamber, the intermediate water tank, the second downward pipeline, the return pipeline, and a space under the piston in the air pressure cylinder,
- whereby after a vacuum is created in the continuous closed space and the water in the main water tank is allowed to enter and propagate through the continuous closed space, the water will flow through the upward pipeline to the first vacuum chamber and into the second vacuum chamber through the nozzle of the first downward pipeline, and then interact with the power generating assembly to generate electricity;
- afterwards the water will be directed, in an auto mode through coordinated operations of the three NC solenoid valves and the NO solenoid valve and up-and-down movement of the piston along with the extension and retraction of the extension spring, to recycle through the continuous closed space to the second vacuum chamber to interact with the power generating assembly in repetitive cycles of power generation.
