An inquiry into the hot air engines of the 19th century

The aim of this book is to provide a circumstantial and detailed information about the hot air engines of the 19th century. The inquiry takes base on the reading and scrutiny of numerous archives between 1800 and 1920, most of them being books, magazines, scientific review, articles, patents.
Reference to these archives will be given on a specific page.

The book will of course present the main inventors, their engines, a description of their operation. It will do it taking into account the technological evolution, giving a special focus to the specific technological problematic the inventors tried to answer.
Minor inventors will also be presented with a special focus on the reason of their failure.

The hot air engine existed during more or less a century and a half and then was abandoned ; a tragic destiny when considering that this engine could be a clean technology for power generation. Will it one day come back and become a technology for the future ?
The book, when presenting the engines, will analyze the causes of its dismissal. It will also benchmark its position in comparison to its competitors, the steam engine and the gas engine. At last it will try to address whether this technology can be one day sustainable.

Numerous inventors started a hot air engine venture, many scientists wrote about this engine, hundreds of patents were filed, thousands of articles have been written. An enormous amount of work has been dedicated to this technology. All of this resulted in an incredible amount of learning and science.
This book, by bringing most of it together in one place, will allow anyone curious about this engine to leverage on a century of acquired knowledge and experience.

NOTE: This book is in writing. It will be updated regularly. Being written by a non English native, the book will unfortunately be tainted with unwished language mistakes.
