00:00From the dawn of civilization, humanity has looked to the sky and asked,
00:04how can we capture the wind?
00:07Our journey begins in 5000 BC,
00:10where the Egyptians first converted wind energy into linear motion,
00:14powering the earliest sailboats.
00:16By 200 BC, the Chinese had developed vertical axis systems for pumping water,
00:22though their efficiency was below 5% due to negative drag.
00:27Across the world, Persian engineers in the 7th century built windmills with reed blades,
00:32using protective walls to channel the wind for greater power.
00:37Europeans revolutionised the design with the postmill,
00:40allowing the entire structure to rotate and always face the wind.
00:44The 16th century saw the rise of the mighty Dutch tower mill.
00:49Its sturdy brick tower and advanced gears harnessed wind to grind grain on an industrial scale.
00:56By the 18th century, windmills became automated marvels,
01:00with fan tails, shutters and governors working in perfect harmony to control their power.
