The volt is the derived unit for electric potential, electric potential difference (voltage), and electromotive force. It is named after the Italian physicist Alessandro Volta (1745–1827).
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 an infinite 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 EcoSailingProject.
A ferry is a vessel used to carry passengers, and sometimes vehicles and cargo, across a body of water. A passenger ferry with many stops, such as in Venice, Italy, is sometimes called a water bus or water taxi.
An electric vehicle (EV) is a vehicle that uses one or more electric motors for propulsion. It can be powered by a collector system, with electricity from extravehicular sources, or it can be powered autonomously by a battery. EVs include, but are not limited to, road and rail vehicles, surface and underwater vessels, electric aircraft and electric spacecraft.
An automotive battery or car battery is a rechargeable battery that is used to start a motor vehicle. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle. Once the engine is running, power for the car's electrical systems is still supplied by the battery, with the alternator charging the battery as demands increase or decrease.
The Sognefjord or Sognefjorden, nicknamed the King of the Fjords, is the largest and deepest fjord in Norway. Located in Vestland county in Western Norway, it stretches 205 kilometres (127 mi) inland from the ocean to the small village of Skjolden in the municipality of Luster.
A solar vehicle or solar electric vehicle is an electric vehicle powered completely or significantly by direct solar energy. Usually, photovoltaic (PV) cells contained in solar panels convert the sun's energy directly into electric energy. The term "solar vehicle" usually implies that solar energy is used to power all or part of a vehicle's propulsion. Solar power may be also used to provide power for communications or controls or other auxiliary functions.
A plug-in hybrid electric vehicle (PHEV) is a hybrid electric vehicle whose battery pack can be recharged by plugging a charging cable into an external electric power source, in addition to internally by its on-board internal combustion engine-powered generator. Most PHEVs are passenger cars, but there are also PHEV versions of commercial vehicles and vans, utility trucks, buses, trains, motorcycles, mopeds, and even military vehicles.
A battery charger, or recharger, is a device that stores energy in a battery by running an electric current through it.
A battery electric bus is an electric bus that is driven by an electric motor and obtains energy from on-board batteries. Many trolleybuses use batteries as an auxiliary or emergency power source.
M/F Tycho Brahe is a Danish battery-electric car-ferry owned by ForSea Ferries that operates on the HH Ferry route. It has been in use since 1991. The ship is bidirectional, which means it can change direction without turning around, so no time is lost for this. The ship is also able to accelerate and decelerate quite quickly to and from her maximum speed of 14 knots.
An electric vehicle battery is a battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). These batteries are usually rechargeable (secondary) batteries, and are typically lithium-ion batteries. These batteries are specifically designed for a high ampere-hour capacity.
The lithium-titanate or lithium-titanium-oxide (LTO) battery is a type of rechargeable battery which has the advantage of being faster to charge than other lithium-ion batteries, but the disadvantage of having a much lower energy density.
A battery electric multiple unit (BEMU), battery electric railcar or accumulator railcar is an electrically driven multiple unit or railcar whose energy is derived from rechargeable batteries driving the traction motors.
A plug-in electric vehicle (PEV), also known as new energy vehicle (NEV) in China, is any road vehicle that can be recharged from an external source of electricity, such as wall sockets, and the electricity stored in the rechargeable battery packs drives or contributes to drive the wheels. PEV is a subset of electric vehicles that includes all-electric, or battery electric vehicles (BEVs), and plug-in hybrid vehicles (PHEVs). Sales of the first series production plug-in cars began in December 2008, with the introduction of the BYD F3DM plug-in hybrid, and the all-electric Mitsubishi i-MiEV in July 2009, but retail sales only gained traction after the introduction of the mass production all-electric Nissan Leaf and the plug-in hybrid Chevrolet Volt in December 2010.
Ytre Oppedal is a village and ferry terminal in Gulen Municipality in Vestland county, Norway. It lies on the shores of the Oppedalsvika inlet along the south side of the Sognefjorden, east of where the Risnefjorden empties into the Sognefjorden. The village lies on both sides of the river Oppedalselva, which flows directly to the ferry port. The village of Brekke lies west of Ytre Oppedal, on the opposite side of the Risnefjorden.
Lavik is a village in Høyanger Municipality in Vestland county, Norway. The village is located on the northern shore of the Sognefjorden, approximately 100 kilometres (62 mi) north of the city of Bergen and about 50 kilometres (31 mi) west of the municipal center of Høyanger. Lavik is situated about 40 kilometres (25 mi) west of the villages of Kyrkjebø and Austreim, and about 25 kilometres (16 mi) southwest of the village of Vadheim. In 2001, the Lavik area had a population of about 1000 people, with about 285 living in the village of Lavik.
MV Catriona is a pioneering diesel electric hybrid passenger and vehicle roll-on, roll-off ferry built for Caledonian MacBrayne for the Claonaig–Lochranza crossing. She is the third hybrid ferry commissioned and owned by Caledonian Maritime Assets, one of three such ferries in the world to incorporate a low-carbon hybrid system of diesel electric and lithium ion battery power. The ferries are sea-going and are nearly 46 metres (150 ft) long, accommodating 150 passengers, 23 cars or two HGVs.
MV Victoria of Wight is a ship sailing on the Portsmouth to Fishbourne route operated by Wightlink. She entered service on 26 August 2018. Built by the Cemre Shipyard in Yalova for £30 million, she is the newest ship in the fleet and completed Wightlink's £45 million investment in the Portsmouth to Fishbourne route. In addition, upon introduction into service Victoria of Wight became the largest ship in the fleet and the new flagship.
E-ferry Ellen is a pioneering electric car ferry. She operates the 22 NM route between the islands of Ærø and Als in Southern Denmark.
