The Thousand League Fleet
While Daifang engines became ubiquitous in households and factories, relieving man and beast alike, the driving force behind this development was actually shipping and warfare. In order for the technology to really mature, heavy investments were necessary.
Obviously the time between putting money into research, building production sites and profits was too much for most private enterprises to consider. Luckily soon enough military and logistical uses for the invention were found. Thus the state could stem the financial burden of making these early engines sufficiently efficient and building up the capacities for mass production.
The background of the story began in between 420-581. During that period the world’s first paddle wheel ship was build. The ships were used by Admiral Wang Zhene in his campaign against theQiang people in 418 AD. A wheel with boards or paddles affixed around its circumference, instead of the oars, was used to propel the ship. The use of a constantly moving device, rather than an intermittent device, signified a critical technological improvement in shipbuilding.
Song Wheeled Ship (1)
By the time of the Song Dynasty, powder and ships had become two of the most important military weapon. Historical records show that General Han Shizhong defeated the enemy largely due to the use of paddle wheel ships in the famous Huangtiandang Battle. Another record shows that Yu Yuwen's paddle wheel ships once "startled and astonished" the enemy troops. With the improvement of the shipbuilding technology, the number of paddle wheels also increased from 2 to 4, 8, 20, or even 32.
The standard Chinese term "wheel ship" was used by the Song period, whereas a litany of colorful terms were used to describe it beforehand. In the 12th century, the Song government used paddle-wheel ships en masse to defeat opposing armies of pirates armed with their own paddle-wheel ships. Obviously the Daifeng engine was just the missing piece to make China’s truly invincible. And once the government operated factories were churning out engines like rice cake, it became lucrative to privatize faculties in peace times. Once the country was flooded in cheap engines, a surplus of engineers as set free, nothing could turn back the tide of industrialization.
