Qianli chuan

Qianli chuan (Chinese: 千里船; pinyin: qiānlǐchuán; lit.: 'thousand league boat'[1][2]) were paddle wheel boats used in medieval China. The boats were driven by human pedaling and were able to cruise hundreds of kilometers per day with no wind blowing.[1]

History

Qianli chuan were invented in the late 5th century AD during the Southern Qi Dynasty and the invention is attributed to the ancient Chinese astronomer and mathematician Zu Chongzhi.[1][3][2][4] References made to the boat were made recalling various tests on the Xinting River, south of modern Nanjing. The boat was proven to be able to cruise several hundred kilometers in a single day without any wind blowing.[1] Late 8th century AD records have descriptions of the Qianli chuan as a type of naval boat that had two wheels found on its sides that was propelled by treadmills.[2]

It uses a bunch of sieves running on soul sand, gravel and dust to make ore pieces and gems and such, as well as a void ore miner (I resent EnvironmentalTech, but apparently you need the crystals from it), as well as a laser drill, as well as an ender chest from the lunar mining site. It uses Ender IO machines for smelting/some grinding because they're really, really fast, Mekanism 5x ore processing (which constantly ends up backlogged) for a few rarer things, and 4x ore processing (still horribly backlogged) for most of the rest.
