  • Patent number: 10964955
    Abstract: Methods and systems for providing battery backup power to a home or other building are disclosed. Methods and systems include a fluid container holding an electrolyte solution. The electrolyte solution is prevented from flowing through an array of galvanic cells having annular flow paths via a fluid flow control mechanism, such as a valve, which is energized by an external power source. When the external power source is removed, such as during a power outage, the fluid flow control mechanism is deenergized and electrolyte solution is allowed to flow through the galvanic cell array, generating electric current. Energy produced by the system then powers the home or other building until the external power source returns, which in turn closes the fluid flow control mechanism and ceases energy production by the system.
