Etymology[ edit ] "Gasoline" is a North American word that refers to fuel for automobiles. The Oxford English Dictionary dates its first recorded use to when it was spelled "gasolene".
The term "gasoline" was first used in North America in On 27 Novemberthe British publisher, coffee merchant and social campaigner John Cassell placed an advertisement in The Times of London: The Patent Cazeline Oil, safe, economical, and brilliant … possesses all the requisites which have so long been desired as a means of powerful artificial light.
Cassell discovered that a shopkeeper in Dublin named Samuel Boyd was selling counterfeit cazeline and wrote to him to ask him to stop. Carless registered a number of alternative names for the product, but "petrol" nonetheless became the common term for the fuel in the British Commonwealth.

Coal was the fuel that powered their navies. Though both Britain and Germany had natural coal reserves, new developments in oil as a fuel for ships changed the situation. Coal-powered ships were a tactical weakness because the process of loading coal was extremely slow and dirty and left the ship completely vulnerable to attack, and unreliable supplies of coal at international ports made long-distance voyages impractical.Nov 07, · The essence of trading is that it seeks to rectify the anomaly of the double coincidence of wants.
