Mechanical engineering has always been to increase production, improve labor productivity, improve the economy of production, that is, to improve the interests of mankind as the goal to develop and develop new mechanical products. In the future era, the research and development of new products will take reducing resource consumption, developing clean renewable energy, controlling, reducing and even eliminating environmental pollution as the goal task of super-economy. The development of engineering technology not only improves the material civilization and living standard of human beings, but also destroys the natural environment. Since the mid-20th century, two serious problems have been exposed: the massive consumption of resources (the most serious of which is energy) and the serious pollution of the environment. In terms of energy, the dependence on non-renewable fossil energy can be reduced by improving nuclear fission power plant, developing solar energy, geothermal energy, tidal energy, sea water temperature difference energy, etc. In the long run, nuclear fusion is a promising and almost endless source of energy for the future. Based on the future achievements of nuclear physics, mechanical engineering, together with other engineering technologies, will complete the development and promotion of nuclear fusion power plants in the 21st century, which may completely solve the world's energy problems. The use of this new energy can also reduce carbon dioxide emissions to the atmosphere.
