Lifeboats are rescue boats that don't sink even if they capsize (turn upside down). These are small boat carried on the vessel and used in case of emergency. By law, the total capacities of all lifeboats far exceed the total number of passengers and crew members onboard. Lifeboats have traditionally been made out of wood, and some still are. However, these days, it is very common for a lifeboat to be made out of durable plastic or water-resistant tarp. A plastic lifeboat is usually inflatable. Some lifeboats are even more capably equipped to permit self-rescue; containing such supplies as a radio, an engine and/or sail, heater, basic navigational equipment, solar water stills, rainwater catchments and fishing equipment. Furthermore, they are often referred to as life rafts.
Born on 9 July 1802 at Williamstown, Vermont, Thomas Davenport was an American Vermont blacksmith who constructed the first American DC electric motor in 1834 and built an electric car in 1835. Based on the concept of the battery-powered electric motor, he operated a small model car on a short section of track which provided the way for the later electrification of streetcars.
