Description

Power generation device using air pressure inside the hull The present invention relates to a power generation device, and more specifically, to a power generation device that generates electricity using air pressure inside an enclosure. Generally, a generator is a device that receives mechanical energy from an external power source and converts it into electrical energy, and external power sources used include turbines, water turbines, electric motors, and engines. Methods of generating electrical energy using external power sources include power generation that directly utilizes natural forces, such as hydroelectric power generation utilizing the difference in water's potential energy and wind power generation utilizing the power of wind; additionally, there are thermal power generation and nuclear power generation that generate electricity through artificial methods using natural resources extracted from nature, such as petroleum, coal, or uranium. As is well known, the power generation principle of a generator using an external power source as described above is based on the relative relationship between electrons and magnetic fields within a conductor, and when a conductor cuts through magnetic flux, a voltage is induced across the ends of the conductor, and current flows due to the induced voltage. At this time, since the magnitude of the induced voltage (E) is related to the magnetic flux density (B), the length (I) of the conductor in the magnetic field, and the speed (V) of the conductor, external power is required for the operation of the generator, and mechanical energy must be continuously supplied from an external power source. However, in the case of the aforementioned thermal power generation or nuclear power generation, the generator is operated using thermal energy generated by the combustion of natural resources or nuclear reactions. Consequently, not only is the efficiency of conversion into electrical energy reduced due to the loss of thermal energy, but many environmental problems associated with power generation are also emerging, such as global warming caused by the generation of carbon dioxide from the combustion of fuel, radioactive leakage from nuclear reactions, and the problem of nuclear waste disposal. Furthermore, natural resources such as coal and oil, which are representative fossil fuels, have limited reserves and are predicted to deplete their available energy. Consequently, serious energy issues are being raised regarding the need to develop new alternative energy sources due to the trend of continuously rising oil prices. Additionally, there are problems associated with environmental restrictions that accompany the use of natural energy sources such as hydropower, wind power, or solar energy.
