Also in 1815, but before Davy presented his first lamp to the public, George Stephenson (one of the pioneers in the development of the steam locomotive) quite independently was also working on a safe miner s lamp. He discovered during his experiments that flame produced by a particular gas at a given concentration will not pass through a tube smaller than a certain diameter. While most people have heard of Davy s lamp (it seems that Sir Humphrey received all the credit), it was actually Stephenson s discov-...

There are too many inventors and little cooperation in finding the best combination of suspension, guidance, propulsion, and control. A national competition would be vei"y helpful, such as the locomotive competition in 1829 when George Stephenson s Rocket heat several competing designs by hauling a coach of passengers at 39 km/h (24 mph).

Stephenson derived immediate satisfaction from his mechanical accomplishments, there is some evidence that he resented or disdained the public acclaim through his rejection of invitations to join the Royal Society or to accept Knighthood. Despite his brilliance, his relative late education kept him from feeling socially accepted. This may have started with a grudge as early as 1815, when he lost out in a patent dispute with a more privileged rival over a safety lamp that George invented.

The first practical locomotive, a steam-driven behemoth designed in 1829 by the British engineer George Stephenson, managed to huff along with a full load of passengers at a speed of 24 miles per hour. Not bad for its time.

A lamp used in areas of combustible gas that prevents ignition of the gas by the provision of a wire screen, which encloses the lamp flame. The wire screen absorbs the heat of the (oil lamp) light source before it can contact a gas, thereby preventing its ignition. Invented by the British chemist Sir Humphry Davy (1778-1829) in 1815 for use by coal miners where firedamp was present. George Stephenson (1781-1848), a British inventor and engineer, also independently invented a similar miner s safety lamp at about the same time but shared credit for this invention with Sir Humphry Davy. 

Simultaneously with Davy, George Stephenson, afterwards the famous locomotive engineer but then an obscure man, began to experiment, and devised a lamp in which a candle or oil lamp was enclosed in a lantern, and air admitted below through holes in a metal plate which could be partly closed by moveable discs. Stephenson says his first lamp was tried on 21 October 1815, when it was carried with safety (apparently it went out) a modified lamp was tried on 4 November and burnt better, a third on 24 November. He does not explain the principle, but the Report (iSiy) says he concluded in August, first, that the gas, produced by combustion in a Lamp, would prevent the communication of any explosion through the chimney of the Lamp upwards and secondly, that if the Lamp was supplied with air from a tube below, that tube would prevent the communication of any explosion downwards. He calls firedamp hydrogen gas .
