It's very blue. To put it bluntly, a steam engine boils water. If a steam engine is used as an engine, the volume is one thing, and the fuel supply is another. And in winter, won't the water inside freeze? Antifreeze still needs to be invented; as for fuel engines, the first thing is that the metal smelting process is not up to standard. When New China was founded, it was still in the city with the aid of the Soviet Union, let alone doing it alone. The second is the issue of fuel, how to mine the oil field, what machinery should be used for mining, how to design the mining machinery, what materials should be used to design it, how to build the manufacturing workshop, and it must be tested after manufacturing. If it is not up to standard, it must be redesigned. The power must also be taken into account, whether it should be a steam engine or an electric motor. The third is how to process the extracted crude oil into vehicle fuel, and how to store and transport it. To sum up, the automobile will definitely not appear in the short term, because its appearance is fundamentally based on the development of cutting-edge technology in the current era; if it is to appear on a large scale, it can only occur after its technology has matured and been industrialized.
