The Greatest Philanthropist As an English army officer, Thomas Savery was once ejected from the Lord of the Admiralty's office as a lunatic because he proposed a ship that could be propelled by side-mounted wheels rather than by wind or oars.
The Family of Steam Engines : Unfit to be an Artificial Horse
James Watt’s Engine :The Artificial Horse Evolved over 100 Years James Watt radically improved Newcomen's engine (1769) by condensing the steam outside the cylinder .

The Otto’s Artificial Horse Nicolaus Ottowas's first occupation was as a traveling salesman selling tea, coffee, and sugar. He soon developed an interest in the new technologies of the day and began experimenting with building four-stroke engines. After meeting Eugen Langen, a technician and owner of a sugar factory, Otto quit his job, and in 1864, the duo started the world's first engine manufacturing company N.A. Otto & Cie (now DEUTZ AG, Köln). In 1867, the pair were awarded a Gold Medal at the Paris World Exhibition for their atmospheric gas engine built a year earlier.
Why road steam disappeared Road steam disappeared through becoming uneconomical to operate. By 1921, steam tractors had demonstrated clear economic advantages over horse power for heavy hauling and short journeys. However, petrol lorries were starting to show better efficiency and could be purchased cheaply as war surplus. On a busy route a 3-ton petrol lorry could save about £100 per month compared to its steam equivalent, in spite of restrictive speed limits, and relatively high fuel prices and maintenance costs
Diesel’s Artificial Horse Diesel was graduated in January 1880 with highest academic honours. Diesel understood thermodynamics and the theoretical and practical constraints on fuel efficiency. He first worked with steam, his research into thermal efficiency and fuel efficiency leading him to build a steam engine using ammonia vapour. He then began designing an engine based on the Carnot cycle, and in 1893, Diesel published a treatise entitled Theorie und Konstruktion eines rationellen Wärmemotors zum Ersatz der Dampfmaschine und der heute bekannten Verbrennungsmotoren. Theory and Construction of a Rational Heat-engine to Replace the Steam Engine and Combustion Engines Known Today.

Kelvin Planks postulate “It is impossible to construct a heat engine which produces no other effect than the extraction of heat from a single source and the production of an equivalent amount of work” On the other side It is possible to construct a heat engine which produces no other effect than the extraction of work from a single source and the production of an equivalent amount of heat
