Rotor for the Smith Putnam wind turbine being assembled at the Budd plant near Philadelphia sometime in the early 1940s.

On this date in 1941, the first commercial-scale wind turbine was connected to the electrical grid in the United States. It was a milestone in the development of wind energy. The giant Smith-Putnam turbine proved that a wind turbine could be used to generate commercially quantities of electricity in parallel with other forms of generation in North America.

No. That title isn’t click bate. Long ago, in a land far away, I had to give a speech on the future of wind energy. That’s not noteworthy; I do it all the time. What was noteworthy, though, was that I had to compete with can-can dancers. If this was fiction, no one would believe it.

In 1919 the utility installed a wind turbine at Buddinge and connected it to its lines—a first worldwide, a full two decades before the Smith-Putnam machine in Vermont was connected to the grid.

Today marks the liberation of the Buchenwald concentration camp in 1945 by the 6th armored division of the US Third Army. Buchenwald is significant for several reasons. 56,000 people died in the camp, some one-quarter of those imprisoned.

In the research for my new book, Wind Energy for the Rest of Us, I came across several unsung heroes of wind energy development. One of those was French engineer Louis Vadot.

The Madison County (Indiana) Historical Society was able to locate the photo that I’d seen on display in mid 2015 of Charles E Miller’s 1926 wind turbine in Anderson, Indiana.

Miller is practically unknown among historians for his contribution to wind energy technology. He could be an unsung Hoosier hero for his invention of the pitchable blade tip.

In the research for my forthcoming book, Wind Energy for the Rest of Us, I came across a lot of intriguing information about the development of wind energy. While fascinating, much of it is too far afield for one book on wind energy. So I am posting these items on my web site so they’re searchable–by me as well as others.

Miller was an inveterate inventor and the Madison County (Indiana) Historical Society has an exhibited devoted to his work. It was here that I first saw a clipping of his wind turbine.
