Скачать или смотреть How Ancient Chinese Treasure Ships Survived Months at Sea Without Refrigeration

In the early 1400s, Admiral Zheng He commanded the largest naval expeditions the world had ever seen. His fleets crossed the Indian Ocean with over 200 ships and tens of thousands of crew members. Long before refrigeration, antibiotics, or modern medicine.

And yet…
They suffered no recorded scurvy outbreaks.
Their food didn’t rot.
Their ships stayed afloat even when damaged.

This documentary breaks down five ingenious technologies that made it possible:

Sprouted soybeans that quietly prevented scurvy
Watertight bulkheads that protected food and ships
Fermented soy paste (jiang) that preserved protein for months
Integrated desalination systems using ship furnaces
Floating ecosystems with livestock and onboard food production
