Solar-powered Boat
An electric boat is a powered watercraft driven by electric motors, which are powered by either on-board battery packs, solar panels or generators. While a significant majority of water vessels are powered by diesel engines, with sail power and gasoline engines also popular, boats powered by electricity have been used for over 120 years. Electric boats were very popular from the 1880s until the 1920s, when the internal combustion engine became dominant. Since the energy crises of the 1970s, interest in this quiet and potentially renewable marine energy source has been increasing steadily, especially as more efficient solar cells have become available, for the first time making possible motorboats with a theoretically infinite cruise range like sailboats. The first practical solar boat was probably constructed in 1975 in England. The first electric sailboat to complete a round-the-world tour (including a transit of the Panama Canal) using only green technologies is EcoSailingPr ...

Panama Canal
The Panama Canal () is an artificial waterway in Panama that connects the Caribbean Sea with the Pacific Ocean. It cuts across the narrowest point of the Isthmus of Panama, and is a Channel (geography), conduit for maritime trade between the Atlantic and Pacific Oceans. Lock (water navigation), Locks at each end lift ships up to Gatun Lake, an artificial fresh water lake Above mean sea level, above sea level, created by damming the Chagres River and Lake Alajuela to reduce the amount of excavation work required for the canal. Locks then lower the ships at the other end. An average of of fresh water is used in a single passing of a ship. The canal is threatened by low water levels during droughts. The Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous route around the southernmost tip of South America via the Drake Passage, the Strait of Magellan or the Beagle Channel.

Anthony Reckenzaun
Anthony Reckenzaun (23 March 1850 – 11 November 1893) was an electrical engineer who worked in the UK and the United States. Reckenzaun worked on electric tramcars and electric boats. He is probably best known for applying worm gear drive to tramcars. This was not a great success on full-size vehicles but was later very widely used on electrically powered model railway locomotives. Early life and education Born in Graz, Austrian Empire on 23 March 1850, and died of consumption at his home in Stockwell, London at 2 a.m. on 11 November 1893. He was 43 years old. At an early age he had first-hand opportunities of practical engineering, seeing the operations in the ironworks of his father who carried out large contracts for brewery plants, tanneries, buildings and railway materials - especially for the Hungarian railways. After receiving a practical education at the Technical School in Graz, and with a view to widening his engineering knowledge, he moved to England in 1872 ...

Propeller
A propeller (often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from stern sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the wat ...

Gustave Trouvé
Gustave Pierre Trouvé (2 January 1839 – 27 July 1902) was a French electrical engineer and inventor in the 19th century. A polymath, he was highly respected for his innovative skill in miniaturization. Early life and education Gustave Trouvé was born on 2 January 1839 in La Haye-Descartes (Indre-et-Loire, France) into a modest family. His father, Jacques Trouvé, was a cattle dealer. In 1850, he studied to be a locksmith in Chinon College, then from 1854 to 1855 at the École des Arts et Métiers in Angers. His studies were incomplete due to poor health, and he left his local region for Paris where he obtained a job with a clockmaker. Paris From 1865 Trouvé set up a workshop in central Paris where he innovated and patented many widely differing applications of electricity, regularly reported on by popular science magazines of the time such as ''La Nature''. He invented a carbon-zinc pocket-sized battery to power his miniature electric automata which soon became very popul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Outboard Motor
An outboard motor is a propulsion system for boats, consisting of a self-contained unit that includes engine, gearbox and propeller or jet drive, designed to be affixed to the outside of the transom. They are the most common motorised method of propelling small watercraft. As well as providing propulsion, outboards provide steering control, as they are designed to pivot over their mountings and thus control the direction of thrust. The skeg also acts as a rudder when the engine is not running. Unlike inboard motors, outboard motors can be easily removed for storage or repairs. In order to eliminate the chances of hitting bottom with an outboard motor, the motor can be tilted up to an elevated position either electronically or manually. This helps when traveling through shallow waters where there may be debris that could potentially damage the motor as well as the propeller. If the electric motor required to move the pistons which raise or lower the engine is malfunction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
