If you were sent to the North-west frontier in the days of the Raj, or tried to keep order in the Persian Gulf, an essential for your comfort would have been your portable Ky-ko fan powered by a hot air engine fuelled by paraffin (kerosene). These were remarkably resilient and long-lasting and continued in use until the 1930s.  They were built by The Model Engineering Company in London. One pint of fuel lasted 10 hours. Here is Julius’ CAD take on the design, in metric of course.

A nice straight-forward project to prepare for summer.
