多年以来,人们一直在努力研制太阳动力机。早在1615年,法国工程师就曾设计了一个太阳热空气泵,利用太阳能加热空气,通过空气膨胀进行抽水。到了十九世纪下半叶,在欧洲,特别在法国太阳动力机得到了进一步的发展,提出和建成了至今仍在采用的各种太阳动力机的设想和试验装置。其中有代表性的是法国学者在1860—1878年之间建造的一系列太阳蒸汽 For many years, people have been working hard to develop solar power machines. As early as 1615, French engineers designed a solar hot air pump that uses solar energy to heat the air and draw water through the expansion of the air. By the second half of the nineteenth century, further developments were made in Europe of solar power machines, especially in France, and the design and testing of various solar power machines still in use were proposed and completed. Among them, a series of solar steam built by French scholars between 1860 and 1878
