Hot Air Engines galore at Greenville 2021

The 2021 Greenville Ohio Power of the Past engine show featured hot air (stirling) engines of all kinds. Large and small engines from pumpers to playthings were well represented.

It's great to see these engines operating and the fans are "cool" too. Thanks for sharing

Neat!!!

Похоже, Стирлинг был образованным человеком с инженерными способностями и лишь в последнюю очередь священником.

Thanks for posting. That was most interesting. Some remarkable examples there. I often wonder how much cooling effect these fans actually give, considering it runs on a heat source ;) The Pakistani one was something I hadn't seen before. Amazing they still make something like that. Cheers Rob

Cooling from the fans is highly effective, especially in a tropical climate in the days without electricity. If the fan is in good condition only a small flame is required which can't be felt a few inches away.

There is still a place for fans of this nature

Where was this show conducting ...I wish I could c them

[@riderericsson]

This was in Greenville, Ohio, USA but they do not feature hot air engines every year.

A small hot air engine paired with a small electric motor as a generator, a voltage stabilizer and a USB port can be used to charge your cell phone when you have no electricity available 😊

I found a few advertisements for these things in some old magazines I have.

Thanks for the video, where can I buy one of this?

Excellent video! I wish I could have attended. 🤠

they remain mysterious machines

Vaya feria de Sterling, muy bueno, saludos.

[@riazhassan6570]

The hot-air engine is a master stroke of intuition and invention. Considering that Stirling was a clergyman rather than mechanic or an engineer, it is remarkable. One wonders why it was not developed further for general use

[@michaelbauers8800]

Doesn't the hot air engine predate Stirling by over 100 years?

[@riazhassan6570]

@@michaelbauers8800 You’re right. One hears speculation about the Wright brothers and the aeroplane, or Watt and the steam engine, since a good bit was going on before them. Workability, usability and viability decide the issue for most people, I think. Stirling’s vision worked pretty well, so it might be fair to associate his name with this machine. No cumbersome, dangerous boilers, just light a fire and get going. Despite this, the steam engine dominated the prime mover scene
