According to Orffyreus’  biographer J. Collins, Orffyreus constructed four major wheels in his lifetime varying from smaller to larger size with capacity to produce more and more power.1 These were exhibited, examined and tested. No fraud was ever detected. Collins has found that in addition to these four well-publicized wheels Orffyreus also constructed three more wheels.  During all tests, the officials who had talked with him were convinced that he was a sincere inventor.

  Orffyreus exhibited his wheels at various towns like Prague, Gera, Leipzig, Drashwitz, and Merseburg, all these were parts of Germany in those times.  The accounts of exhibitions to the public, examinations of these wheels by distinguished persons and all other events and episodes related to the wheels are very interesting to read and are source of vital information.  These events cover major part of the story of Orffyreus.  We have many versions of the story from different authors in which descriptions of the events  vary slightly but main story remains undisputable that Orffyreus invented perpetual motion and demonstrated it without a fraud.   

Let us look into various details of Orffyreus’ wheels that he built in his lifetime with all hope that his work on perpetual motion would get recognition in world of science and technology and eventually bring him a suitable reward. To achieve this goal, he struggled steadfastly through out his life.  In following pages, you will find descriptions of main events that mark his life. You will find arguments, explanations on his wheel and also guess work about their working mechanism put forward by various authors.  In the end, you will also find reconstruction of his wheel by Ramananda.
