A brief account of Orffyreus and his wheel John Collins - Youtube video:
Orffyreus wanted to sell his machine for the sum of £20,000, a fortune in those days, equivalent to well over a million Pounds today. Despite the apparent stupidity of asking such a large sum of money, it was not unique and in fact Bessler based the sum on the one offered by the British Board of Longitude, which, at the same time, was offering £20,000 to the first person to discover a means of locating the exact position of a ship at sea, longitudinally. John Harrison eventually won the money although it took him and his son many years to get all of it from a reluctant British government.

In 1712 Johann Bessler (aka ORFFYREUS) exhibited a machine which he claimed, drew its energy from gravity. Despite nearly twenty years of the most stringent tests, examinations and public trials, not the slightest sign of deception was ever found. Bessler died 33 years later, in poverty, still maintaining that his machine was genuine and there was no convincing evidence to the contrary.He had a number of supporters as well as enemies, and among his champions were some of the most respected men of the day. These men, included Gottfried Leibniz and Christian Wolff, top scientists of the calibre of Newton.
