A locally-distributed power generation method that uses a device using an engine such as a gasoline engine, a diesel engine, and a gas turbine to activate an electric generator to generate a power and a battery of a three-dimensional structure comprising two vessels connected with a member interposed therebetween that permits passage of an ion but does not permit passage of an electron, a powdered active material filled in one of the vessels, and suspended in an electrolytic solution to discharge the electron, and a powdered active material filled in the other vessel and suspended in an electrolytic solution to absorb the electron, wherein conductive current collectors in contact with the powdered active materials are provided in the two vessels, as a battery for storing the generated power, the device for generating the power and the battery of the three-dimensional structure being mounted in transfer and transport means including any of a power-driven two-wheeled vehicle, a power-driven three-wheeled vehicle, a power-driven four-wheeled vehicle and a ship that travels by the engine and a power of an electric motor driven by the power from the battery, and connects the battery of the three-dimensional structure mounted in the transfer and transport means to an inverter installed in a house or an office, to enable to power generated in the electric generator of the transfer and transport means to be used in a load in the house or the office when the transfer and transport means is not moving, thereby utilizing the transfer and transport means which is not moving as fixed power generation equipment for the house or the office,
- that supplies high-temperature substances or/and low-temperature substances generated in the transfer and transport means which is not moving to the house or the office to perform cogeneration.
