"The word ""dynamo"" (from the Greek word dynamis (δύναμις), meaning force or power) was originally another name for an electrical generator, and still has some regional usage as a replacement for the word generator. The word ""dynamo"" was coined in 1831 by Michael Faraday, who utilized his invention toward making many discoveries in electricity (Faraday discovered electrical induction) and magnetism. The original ""dynamo principle"" of Wehrner von Siemens or Werner von Siemens referred only the direct current generators which use exclusively the self-excitation (self-induction) principle to generate DC power. The earlier DC generators which used permanent magnets were not considered"
"Henry Wilde (engineer) Henry Wilde (1833 – 28 March 1919) was a wealthy individual from Manchester, England who used his self-made fortune to indulge his interest in electrical engineering. He invented the dynamo-electric machine, or self-energising dynamo, an invention for which Werner von Siemens is more usually credited and, in fact, discovered independently. At any rate, Wilde was the first to publish, his paper was communicated to the Royal Society by Michael Faraday in 1866. The self-energising dynamo replaces the permanent magnets of previous designs with electro-magnets and in so doing achieved an enormous increase in power. The machine was"
"Dynamite Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay) and stabilizers. It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht, and patented in 1867. It rapidly gained wide-scale use as a more powerful alternative to black powder. Today dynamite is mainly used in the mining, quarrying, construction, and demolition industries. Dynamite is still the product of choice for trenching applications, and as a cost-effective alternative to cast boosters. Dynamite is occasionally used as an initiator or booster for AN and ANFO explosive charges. Dynamite was invented by Swedish chemist Alfred"

The subject was ""Railway Train Intercommunication"" and he described a system fitted to the London and North Western Railway Royal Train. In 1860, Samuel married Emily Andrews and the couple had seven children. Samuel died at Abbottsacre Lodge, Abbott's Road, Winchester on 4 August 1921. Samuel Alfred Varley Samuel Alfred Varley (1832–1921) was an English electrical engineer. He was one of ten children born to Cornelius Varley and Elizabeth Livermore Straker."

The Woolrich Electrical Generator of 1844, now in Thinktank, Birmingham Science Museum, is the earliest electrical generator used in an industrial process. It was used by the firm of Elkingtons for commercial electroplating. The modern dynamo, fit for use in industrial applications, was invented independently by Sir Charles Wheatstone, Werner von Siemens and Samuel Alfred Varley. Varley took out a patent on 24 December 1866, while Siemens and Wheatstone both announced"
"of the single-pole electric starter, both the stationary and the revolving parts were electromagnetic. About 1856 he formulated the concept of the dynamo about six years before Siemens and Wheatstone but did not patent it as he thought he was not the first to realize this. His dynamo used, instead of permanent magnets, two electromagnets placed opposite to each other to induce the magnetic field around the rotor. It was also the discovery of the principle of dynamo self-excitation, which replaced permanent magnet designs. The dynamo was the first electrical generator capable of delivering power for industry. The modern dynamo,"

While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines.

John Dalton was born into a Quaker family in Eaglesfield, near Cockermouth, in Cumberland, England. His father was a weaver. He received his early education from his father and from Quaker John Fletcher, who ran a private school in the nearby village of Pardshaw Hall. Dalton's family was too poor to support him for"

He patented improvements in lead-acid batteries and dynamos, and was a pioneer of manufacturing equipment that powered electric tramways and electric lighting. He invented the smokeless fuel Coalite. He formed the first company to distribute electricity over a wide area. He was described by Lord Kelvin as ""the Edison of Europe"". Parker was born at Lincoln Hill in Coalbrookdale, Shropshire, son of Thomas Wheatley Parker and Ann ""née"" Fletcher. His father was a moulder at the Coalbrookdale Ironworks."
"in excess of £1.5 million, he was a prominent investor in West Australian mines. The invention of the dynamo in 1867 led to a switch from Siemens' previous strength in light-current products to heavy-current products and processes. The world's first modern high-voltage power station was opened in 1891, Deptford East. Designed in 1887 by 23-year-old former Siemens' apprentice Sebastian de Ferranti it was erected by the London Electricity Supply Corporation on the Thames bank at Deptford Creek, two and a half miles west of Siemens' Woolwich site. Berlin was anxious that the London business should break its reliance on the"

He also studied the forces involved in these separations, inventing the new field of electrochemistry. In 1799 Davy experimented with nitrous oxide and became astonished that it made him laugh, so he nicknamed it ""laughing gas"", and wrote about"

Their electrolysis methods did not become the basis for industrial production of aluminium because electrical supplies were inefficient at the time; this only changed with the invention of the dynamo, which made creation of large amounts of electricity possible, by Belgian engineer Zénobe-Théophile Gramme in 1870 and the three-phase current, which made transmission of this electricity over large distances possible, by Russian engineer Mikhail Dolivo-Dobrovolsky in 1889. Soon after the discovery, Bunsen moved on to other areas of interest while Deville's work was noticed by Napoleon III; this was the reason why Deville's Napoleon-funded research on aluminium production"

Brush's design modified the Gramme dynamo by shaping the ring armature like a disc rather than a cylinder shape. The field electromagnets were also positioned on the sides of the armature disc rather than around the circumference. After dynamos and motors were found to allow easy conversion back and forth between mechanical or electrical power, they were combined in devices called rotary converters, rotating machines whose purpose was not to provide mechanical power to loads but"

Other notable early developments in chemical explosive technology were Frederick Augustus Abel's development of nitrocellulose in 1865 and Alfred Nobel's invention of dynamite in 1866. Chemical explosions (both intentional and accidental) are often initiated by an electric spark or flame in the presence of Oxygen. Accidental explosions may occur in fuel tanks, rocket engines, etc. A high current electrical fault can create an 'electrical explosion' by forming a high energy electrical arc which rapidly vaporizes metal and insulation material.
