1. A power storage system comprising:
a sheltering space structured to have a power storage mode, an electricity generating mode, and a sheltering mode;
when in the power storage mode, the sheltering space receives a first amount of water to increase a gas pressure until the gas pressure is increased to a second level from a first level;
when in the electricity generating mode, the sheltering space has the first amount of water reduced to generate electricity by reducing the gas pressure from the second level to the third level; and
when in the sheltering mode, reducing the gas pressure within the sheltering space to approximately 1 atm.
