Europe appearing some time in the 12th century. Well a post mill was built above
a central post so it could pivot. With a pivoting mill you could turn to face the [Wind changes sides and the mill follows]
wind, well this was a seriously big deal in Northern Europe where wind patterns are
constantly shifting. If folks couldn't turn their mills they had a really ugly lawn
ornament that just sat there 75% of the time. Well post mills were the most common
type of mill for centuries, they were cheap to build and they usually worked. [People building a post mill]
Then the tower mill hit the scene with a bang. In a tower mill the main body of [Tower mill drops from the sky]
the mill is fixed to the ground and only the very top section turns in the wind.
They usually include a second smaller set of sails on the side of the mill and
these would automatically turn the big sales to face the wind less work for
human beings all you betcha, and isn't that always the goal.. but we're asking [Person in a hammock]
Siri, come on, you thought we were gonna think about something... Anyway tower mills
could be way bigger because they didn't have to spin around completely, the bigger [Much bigger tower mill next to a post mill]

Revolution when wind and water got kicked to the curb in favor of steam and coal
but windmills still had some uses. Well in the mid-1850s a new kind of windmill
was born wind pumps which use wind power to pump water out of deep wells. [Metal windmill spinning]

American Southwest, Australia and South Africa. To farm the way they were used to
farming they needed more water. Well old-school European windmills could pump [Man looking for pizza in the desert]
water out of wells but what were they going to build those huge clunky
mills out of... Cacti? Tumbleweeds? The shattered dream of the indigenous people
they conquered and destroyed.. Well they probably would have tried that last one [Windmill made of hopes and dreams]
if they thought it'd work instead the Halliday wind pump was invented. They were
metal lightweight cheap and soon they were everywhere picture a scenic little [Halliday wind pumps appearing]

Yeah well those metal wind pumps were so common that they changed the landscape
of the American West and the stage sets of many future productions of Oklahoma. [Halliday wind pump on stage]
(Singing) "Oklahoma, blowing in the wind" all that. Yeah well theatre fact, all actors know
