As an enthusiast of Stirling Cycle Engines, I am always excited when I read and learn something new about them, as I'm sure some of you readers will be.

Stirling Cycle Engines were applied to power many types of early devices, like water pumps, dental drills, and so on. In fact, there was a time when hot air could really cool you off. In the gas lamp era, before electricity became widespread, hot air engines were applied to fans. Many enthusiasts are familiar with, for example, Dr. James R. Senfts' model version MORIYA. However, an array of companies built hot air engine fans commercially, such as the Lake Breeze, just to name one. Many of these fans were similar to present day electric fans, in that they were portable and designed for individual use. They can occasionally be spotted in older (or very authentic) motion pictures. Ceiling fans were also built, often belt-driven from a fairly sizable hot air engine.

As electrification spread across the world, electric motors took over the task of keeping things cool, and the manufacturing of hot air engine fans ceased. Or did it?

You see, electricity hasn't gotten everywhere quite yet, and as a result, hot air engine fans were still being commercially manufactured in Pakistan until as recently as five years ago. This fan is a modern version of the original KYKO brand hot air fan sold in England and around the British empire for about ninety years.

From the front, it looks almost like any modern day electric fan, but from the back the hot air engine shows clearly in the shape of the housing, not to mention the tall exhaust chimney, intended to get the heat from the burner up and out of the air stream.
