Which British organisation promotes 'useful mechanical inventions and improvements'?

The Royal Institution of Great Britain (often abbreviated as the Royal Institution or Ri) is an organisation devoted to scientific education and research, based in London. It was founded in 1799 by the leading British scientists of the age, including Henry Cavendish and its first president, George Finch, the 9th Earl of Winchilsea. Its foundational principles were diffusing the knowledge of, and facilitating the general introduction of, useful mechanical inventions and improvements, as well as enhancing the application of science to the common purposes of life (including through teaching, courses of philosophical lectures, and experiments).

Much of the Institution's initial funding and the initial proposal for its founding were given by the Society for Bettering the Conditions and Improving the Comforts of the Poor, under the guidance of philanthropist Sir Thomas Bernard and American-born British scientist Sir Benjamin Thompson, Count Rumford. Since its founding it has been based at 21 Albemarle Street in Mayfair. Its Royal Charter was granted in 1800.
