    A Ruud Type F Size no. 3 instantaneous and automatic water heater from 1906. The Thermal Valve Model, Type F, of the Ruud Instantaneous Automatic Water Heater is a design that allows the user to instantaneously heat water for on demand applications while not heating, thus saving fuel, when not in use.

    John Wright (1808–1844) was a surgeon from Birmingham, England who invented a process of electroplating involving potassium cyanide. The process was patented in 1840 by Wright's associate George Richards Elkington. He was born on the Isle of Sheppey, Kent and was apprenticed to a Dr Spearman in Rotherham, Yorkshire.

    In 1802, Brugnatelli successfully carried out the first gilding electroplating experiments [4] with the coating of carbon electrodes by a metallic film, finally refining the process in 1805 for which he used his colleague Volta's invention of five years earlier, the voltaic pile, to facilitate the first electrodeposition. He hypothesized that ...

    A water heater is still sometimes called a geyser in the UK and South Africa. Maughn's invention influenced the work of a Norwegian mechanical engineer named Edwin Ruud. The first automatic, storage tank-type gas water heater was invented around 1889 by Ruud after he immigrated to Pittsburgh, Pennsylvania (US). The Ruud Manufacturing Company ...

    John Daniell began experiments in 1835 in an attempt to improve the voltaic battery with its problems of being unsteady and a weak source of electric current. His experiments soon led to remarkable results. In 1836, he invented a primary cell in which hydrogen was eliminated in the generation of the electricity.

    Mr. Baker claims that the particular mode of power used in creating the friction is not essential. It may be wind, water, gasoline, or any other source of energy. The most difficult part of the inventor's assertions to prove is that his system will light or heat a house at about half the cost of methods now in use. [5]
