Nebraskan Farmers Were Using Wind Turbines Before Environmentalism Was Invented

To a casual observer of public discourse here in 2024 it seem extremely odd that the issue of replacing coal fired power stations with wind turbines is a matter of controversy, whether in America or Europe it’s an issue which causes some sparks to fly. The Atlantic has a recent article with a set of pictures from a gentler time in which the industrious nature of Nebraskan farmers in the 1890s receives praise as they create a wide variety of home-made wind turbines.

Farmers have always been the best hardware hackers, using what they have at hand to solve their problems and create the things they need. Perhaps out image of agricultural wind power is one of commercially produced wind pumps, but these are the generation of home-made devices which preceded that. Some of them look conventional to modern eyes, but others such as the horizontal “Jumbo” turbines have little equivalent today.

It’s easy to forget with so many energy sources at our disposal, that in the past the locality affected the choice of motive power. The Netherlands doesn’t have windmills because they are pretty, but because hundreds of years ago they lacked handy coal mines or convenient heads of water. Similarly out in the Nebraskan prairies they had plenty of wind, and never the folk to pass up on an opportunity, they made the best of it. And we’re very glad over a century later, that someone took the time to record their work.

If you’re hungry for more old-style wind power, we’ve got you covered, meanwhile 19th century America was no stranger to clever ways to use power.

Help Wanted: Keep the World’s Oldest Windmills Turning

An image of a desert with dramatically cloudy skies. In the middle of the image is a series of clay doorways with vertically-oriented wooden slats surrounding a central pole. These form the basis of a panemone windmill.

While the Netherlands is the country most known for its windmills, they were originally invented by the Persians. More surprisingly, some of them are still turning after 1,000 years.

The ancient world holds many wonders of technology, and some are only now coming back to the surface like the Antikythera Mechanism. Milling grain with wind power probably started around the 8th Century in Persia, but in Nashtifan, Iran they’ve been keeping the mills running generation-to-generation for over 1000 years. [Mohammed Etebari], the last windmill keeper is in need of an apprentice to keep them running though.

In a world where vertical axis wind turbines seem like a new-fangled fad, it’s interesting to see these panemone windmills are actually the original recipe. The high winds of the region mean that the timber and clay structure of the asbad structure housing the turbine is sufficient for their task without all the fabric or man-made composites of more modern designs. While drag-type turbines aren’t particularly efficient, we do wonder how some of the lessons of repairability might be used to enhance the longevity of modern wind turbines. Getting even 100 years out of a turbine would be some wicked ROI.

Wooden towers aren’t just a thing of the past either, with new wooden wind turbines soaring 100 m into the sky. Since you’ll probably be wanting to generate electricity and not mill grain if you made your own, how does that work anyway?
