Windpower

Scattered throughout the dry country, these windmills stand alone, pumping water into stock tanks ... or standing broken and discarded as the homesteaders and ranchers moved on.
The Aeromotor Company began experimenting with wind engines in 1883 and sold its first 24 all-metal windmills in 1888, selling over 20,000 by 1892. Through many changes in operations, names, and ownership, the company still exists, owned by a consortium of ranchers in Texas - having reverted back to its original name.
In 1890, the factory consisted of one large building. Sales were so great that by 1892, the factory had expanded to three buildings, the newest one-story building covering an acre.
By 1904, an 8ft mill cost $25 and a 20ft mill, $300 - but the mills required weekly maintenance. By 1915, an automatic oiler was developed that reduced maintenance to a yearly task rather than weekly.
The owner of the company, LaVerne Noyes, established university scholarships for veterans of WWI, primarily at Univ of Chicago and Iowa State. He died in 1919, leaving the company to a taxable trust. The scholarships are still available.
So are the windmills.

Today (2024 catalog), a basic 8ft windmill on a 21 ft tower weighs 795 lbs and costs just about $8600 and is of the same basic design as the 1888 windmill.
