A submarine is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as boats rather than ships irrespective of their size.
A vehicle is a machine designed for self-propulsion, usually to transport people, cargo, or both. Vehicles include wagons, bicycles, motor vehicles, railed vehicles, watercraft, amphibious vehicles, aircraft, and spacecraft.
An electric boat is a powered watercraft driven by electric motors, which are powered by either on-board battery packs, solar panels or generators.
A ferry is a boat that transports passengers, and occasionally vehicles and cargo, across a body of water. A small passenger ferry with multiple stops, like those in Venice, Italy, is sometimes referred to as a water taxi or water bus.
Cochin International Airport is an international airport serving the city of Kochi, Kerala, in southwestern India. It is located at Nedumbassery, about 25 km (16 mi) northeast of the city center. The airport is the first of its kind to be developed under a public-private partnership (PPP) model in India. This project was funded by nearly 10,000 non-resident Indians from 32 countries. It is the busiest and largest airport in the state of Kerala and the fourth busiest airport in India. As of 2024, the airport caters to more than 63% of the total air passenger traffic in Kerala. It is the fifth-busiest airport in India in terms of international traffic, and the eighth-busiest overall.
Air-independent propulsion (AIP), or air-independent power, is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen. AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels.
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.
A battery charger, recharger, or simply charger, is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage, current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging after the battery has been fully charged and can be recharged by connection to a constant voltage source or a constant current source, depending on battery type.
Kochi is a major port city in the Indian state of Kerala. The city is widely known as the commercial or economic capital of the state of Kerala.
An electric aircraft is an aircraft powered by electricity. Electric aircraft are seen as a way to reduce the environmental effects of aviation, providing zero emissions and quieter flights. Electricity may be supplied by a variety of methods, the most common being batteries. Most have electric motors driving propellers or turbines.
A battery electric vehicle (BEV), pure electric vehicle, only-electric vehicle, fully electric vehicle or all-electric vehicle is a type of electric vehicle (EV) that exclusively uses chemical energy stored in rechargeable battery packs, with no secondary source of propulsion. BEVs use electric motors and motor controllers instead of internal combustion engines (ICEs) for propulsion. They derive all power from battery packs and thus have no internal combustion engine, fuel cell, or fuel tank. BEVs include – but are not limited to – motorcycles, bicycles, scooters, skateboards, railcars, watercraft, forklifts, buses, trucks, and cars.
The West Coast Canal or National Waterway No 3 is a 205 km (127 mi) long inland navigational route located in Kerala, India, which runs from Kollam to Kottapuram. It was declared a National Waterway in 1993. In addition to the main stretch, Champakara and Udyogmandal canals are navigable and connect the industrial centers of Kochi to Kochi port Inland Waterways Authority of India (IWAI) under the Ministry of Shipping is coordinating the task for developing, monitoring and administering national waterways. It is the first National Waterway in the country with 24-hour navigation facilities along the entire stretch. It has been extended to Kozhikode by the National Waterways Act, 2016. The National Waterway 3 mainly passes through the previous Thiruvananthapuram–Shoranur canal.
LOMOcean Marine is a naval architecture and yacht design company based in Auckland, New Zealand.
MS Tûranor PlanetSolar, known under the project name PlanetSolar, founded by the Swiss explorer Raphaël Domjan, is the largest solar-powered boat in the world and launched on 31 March 2010. The vessel was designed and engineered by LOMOcean Marine. In May 2012, the vessel became the first solar electric vehicle ever to circumnavigate the globe taking 584 days between 2010 and 2012.
Electric rickshaws are small three-wheeled vehicles powered by an electric battery and motor. These small electric vehicles do not require petroleum fuel like auto rickshaws but still offer greater mobility than traditional pulled rickshaws. This has led to their popularity and use expanding in some cities since 2008. Electric rickshaws are primarily manufactured in India, Bangladesh, Nepal, and China.
Aditya is a solar-powered ferry operating between Vaikkom and Thavanakkadavu in the Indian state of Kerala. The boat was inaugurated by Kerala Chief Minister Sri. Pinarayi Vijayan and Central Cabinet Minister for Power, Renewable Energy, Sri. Piyush Goyal on 12 January 2017.
Kochi Water Metro (KWM) is an unfinished ferry transport system serving the Greater Kochi region in Kerala, India. When fully operational, it will connect Kochi’s 10 island communities with the mainland through a fleet of 78 battery-operated electric hybrid boats operating along 38 terminals and 16 routes spanning 76 kilometres. It is integrated with the Kochi Metro and serves as a feeder service to the suburbs along the rivers where transport accessibility is limited.
Raphaël Domjan is a Swiss explorer and lecturer. He initiated and completed the first round-the-world trip using solar energy between September 2010 and May 2012 aboard the MS catamaran PlanetSolar. In 2015, he carried out the first polar solar navigation in the Arctic Ocean. He is the founder and pilot of the SolarStratos project, the first solar plane in the stratosphere. In August 2020, he made the first jump off of an electric plane and the first solar free fall. Raphaël Domjan is a pilot, mountaineer, diver and parachutist. He is a member of the Explorer Club of New York as well as the Société des Explorateurs Français.
