1. A geothermal feedback energy storage system comprising:
a water tank;
a controller device;
piston;
a first fluid pipe;
an energy storage capsule;
a generator;
a fluid storage tank; and
a second fluid pipe,
wherein the water tank receives a hot water generated by geothermal heat and converts the hot water into gas;
wherein the controller device is connected to the water tank, and the controller device determines a flow direction of the gas, wherein the flow direction of the gas positions a status of the piston;
wherein the first fluid pipe is connected to the piston, the energy storage capsule, and the generator, and the first fluid pipe is filled with a fluidic substance;
wherein the first fluid pipe is coupled with the energy storage capsule such that the fluidic substance moving through the first fluid pipe is able to flow directly to the generator;
wherein the second fluid pipe is connected to the piston and the fluid storage tank, and the second fluid pipe is filled with the fluidic substance;
wherein the piston is connected to the controller device, and the piston generates a force through the controller device to force the fluidic substance located in the first fluid pipe to the energy storage capsule or the generator,
wherein the generator is connected to the energy storage capsule and the first fluid pipe, and the generator is driven by the fluidic substance to generate electricity;
wherein the energy storage capsule is connected to the first fluid pipe and the energy storage capsule has the fluidic substance and pre-pressurized gas having a pressure no less than 20 atm and wherein the energy storage capsule stores pressure by using the fluidic substance to compress the gas; and
wherein the fluid storage tank is connected to the generator and the second fluid pipe, and the fluid storage tank to receive the fluidic substance acting on the generator.
