The very first self-powered road vehicles were powered by steam engines and by that definition Nicolas Joseph Cugnot of France built the first automobile in 1769 - recognized by the British Royal Automobile Club and the Automobile Club de France as being the first. So why do so many history books say that the automobile was invented by either Gottlieb Daimler or Karl Benz? It is because both Daimler and Benz invented highly successful and practical gasoline-powered vehicles that ushered in the age of modern automobiles. Daimler and Benz invented cars that looked and worked like the cars we use today. However, it is unfair to say that either man invented "the" automobile.

John Henry Google.  He and Al Gore invented the internet and then he went on to invent search engines and toasters.

a car engine that would run on silicone and water.\nwhy?\nbecause i live just next to the sahara which  has long been associated with death , famine,desperation.\nrecently in history fortunes reversed when petroleum exploded from the sand , becoming the (black gold)\ni hope invention of such an engine would serve many goals\n     1  spare the petroleum for industry and manufacture of \n         medicine and other necessities for which it is the best\n        crude material.\n     2 decrease world pollution and green house effect\n     3  cars would be less dangerous because the explosive\n         tendency could be better controlled,so collisions dont necessarily mean explosion fire death.\n    4   cheap transportation for work and recreation(sand is everywhere)\n    5  further flourishing of our area (north africa) where sand \n        threatens to bury us alive, instead of that we can sell it.

The first hand-powered cleaner using vacuum principles may have been the "Whirlwind", invented in Chicago in 1865.\n\nThe first powered cleaner employing a vacuum was patented by H. Cecil Booth, a British engineer, in 1901. He noticed a device used in trains that blew dust off the chairs, and thought it would be much more useful to have one that sucked dust. He tested the idea by laying a handkerchief on the seat of a dinner chair, putting his mouth to it and sucking hard. He nearly choked, but upon seeing the dust and dirt collected on the underside of the handkerchief he realised the idea could work. Booth worked to create a device operating on such principles, and patented such a machine in Britain: the large device, known as the Puffing Billy, was drawn by horses and parked outside the building to be cleaned; suction was then provided by an internal-combustion engine burning petrol (gasoline). However, Booth never achieved great success with his invention.

The Stirling engine, also known as the hot air engine, is a heat engine of the external combustion piston engine type. Its invention is credited to the Scottish clergyman Rev. Robert Stirling in 1816 who made significant improvements to earlier designs and took out the first patent. He was later assisted in its development by his engineer brother James Stirling.\n\nThe Stirling engine works by the repeated heating and cooling of a sealed amount of working gas, usually air or other gases such as hydrogen or helium. The gas follows the behaviour described by the gas laws which describe how a gas' pressure, temperature and volume are related. When the gas is heated, because it is in a sealed chamber, the pressure rises and this then acts on the power piston to produce a power stroke. When the gas is cooled the pressure drops and this means that less work needs to be done by the piston to re-compress the gas on the return stroke, giving a net gain in power available on the shaft. The working gas flows cyclically between the hot and cold heat exchangers.\n\nThe working gas is sealed within the piston cylinders, so there is no exhaust gas, (other than that incidental to heat production if combustion is used as the heat source). No valves are required, unlike other types of piston engines.\n\nSee Wikipedia for more information, above courtesy of Wikipedia.

The inspiration for the earliest motorcycles, and arguably the first motorcycle, was designed and built by the German inventors Gottlieb Daimler and Wilhelm Maybach in Bad Cannstatt (a city district of Stuttgart) in 1885. It was the first petroleum-powered vehicle ever and, but for the provision of a pair of stabilizing wheels, a motorized bicycle, although they called their invention the Reitwagen ("riding car"). They had not set out to create a vehicle form but to build a simple carriage for the engine which was the focus of their endeavours. However,if one counts two wheels with steam propulsion as being a motorcycle, then the first one may have been American. One such machine was demonstrated at fairs and circuses in the eastern US in 1867, built by one Sylvester Howard Roper of Roxbury, Massachusetts. There is an existing example of a Roper machine, dated 1869. It's powered by a charcoal-fired two-cylinder engine, whose connecting rods directly drive a crank on the rear wheel. This machine predates the invention of the safety bicycle by many years, so its chassis is also based on the "bone-crusher" bike.

Sadi Carnot, a French engineer, resulting in his remarkable paper ReÂflexions sur la puissance motrice du feu et sur les machines propres a developper cette puissance (On the Motive Power of Heat) published in 1824 [1]. In his work, Carnot constructed an ideal cycle, which is now well known as the Carnot cycle, and analyzed its thermal efficiency. Carnot showed that:\n\n1. Any engine, using heat from a hot reservoir at temperature Th to do work, has to transfer some heat to a reservoir at lower temperature\nTl.\n\n2.The thermal efficiency of the Carnot cycle was working medium-independent.\n3. No engine could convert into work more of heat taken in at Th\nthan the fraction  known as the Carnot efficiency.\n\nFurthermore, the Carnot principles are only for the cyclic devices (heat engines), stating that:\n1. The efficiency of an irreversible heat engine is always less than the efficiency of a reversible one operating between the same two reservoirs;\n2. The efficiencies of all reversible heat engines operating between the same two reservoirs are the same.

While, indeed, Michał Sędziwój first wrote about oxygen. \n\n A Swedish person named Carl Wilhelm Scheele was a little more scientific in his description and used scientific methods. But, he did not published his findings until after the discovery of Oxygen by Joseph Priestley. Priestley published his discovery, consequently Priestley is usually given the credit.\n\nGet an "A".

His name was Alessandro Volta.  Alessandro Volta discovered the first practical method of generating electricity.  In 1800, he arranged zinc and copper discs in a column and invented the battery.  His most famous invention was the voltic pile. \n\nThese links should give you all the good stuff!
