Description
technical field [0001] The invention belongs to the technical field of energy conversion, and in particular relates to a device for accumulating and utilizing human activity energy. Background technique [0002] Energy is the basis for human survival and social development. The main energy sources in the current society are coal, oil and natural gas; in addition, there are nuclear energy, solar energy, wind energy, tidal energy and biomass energy. , which is not conducive to large-scale promotion. The rapid development of today's society has intensified the consumption of fossil energy, degraded the environment, and seriously threatened the sustainable development of human society. The shortage of global energy and the deterioration of the environment force human beings to seek a cleaner and healthier low-carbon lifestyle. According to the law of energy conservation, effectively saving and utilizing the energy generated by human activities is a way to save energy and devel...
