Aftermath of a boiler explosion on a railway locomotive circa 1850. Hewison (1983) [23] gives a comprehensive account of British boiler explosions, listing 137 between 1815 and 1962. It is noteworthy that 122 of these were in the 19th century and only 15 in the 20th century. Boiler explosions generally fell into two categories.
Rexburg flooded following Teton Dam failure. This is a list of major hydroelectric power station failures due to damage to a hydroelectric power station or its connections. . Every generating station trips from time to time due to minor defects and can usually be restarted when the defect has been remed
Streetcars created enormous demand for early electricity. This Siemens Tram from 1884 required 500 V direct current, which was typical. Much of early electricity was direct current, which could not easily be increased or decreased in voltage either for long-distance transmission or for sharing a common line to be used with multiple types of electric devices.

The Coleman Lantern is a line of pressure lamps first introduced by the Coleman Company in 1914. This led to a series of lamps that were originally made to burn kerosene or gasoline. Current models use kerosene, gasoline, Coleman fuel or propane and use one or two mantles to produce an intense white light.
The basic problem was that large turbines ran most efficiently at around 3000 rpm, while an efficient propeller operated only at about 100 rpm. This required reduction gearing, but designing reduction gearing that could operate at both high rpm and at high power was difficult since any slight misalignment would shake the powertrain to pieces.
'Wilberforce' boiler in section The first recorded boiler of comparable form was used in a railway locomotive, Hackworth's 'Wilberforce' class of 1830. [2] This had a long cylindrical boiler shell similar to his earlier return-flued 'Royal George' , but with the return flue replaced by a number of small firetubes, as had been demonstrated so effectively by Stephenson with his 'Rocket' a year ...
