Passenger Trains.

Passenger trains carry passengers over long distances and are usually long and fast. A growing type of passenger train used for long distances is the high speed rail. These trains can run at speeds up to 500km/hour. To achieve these speeds, a technology called magnetic levitation has been in research and development to be deployed….

Wind Turbines.

Wind turbines also known as wind energy converter are used to convert the kinetic energy of the wind into electrical energy. They come in two types, vertical and horizontal. The smallest turbines are used for charging batteries for domestic use while the larger ones are used to generate electricity for homes. Wind farms which refer…

Coal fired power plants.

Coal fired power plants utilize coal to generate electricity. They are the most commonly used of all power plant types. They have been used for so many years by countries in Europe and the US but because of global warming concerns and environmental pollution these plants are being closed down in phases and replaced by…

Satellites

A satellite is an object that has been placed in space, revolving in an orbit. Satellites are classed into natural satellites and artificial satellites. Natural satellites include, the sun, moon, stars, artificial satellites are the objects made by man and placed in orbits in outer space and used for communication and geographical survey of the…

Submarines

Submarines are vessels designed to move underwater. They are capable of independent operations with inbuilt power plants capable of supplying power to the vessel for extended periods. Submarines are different from submersibles which are usually launched from submarines or bigger surface ships and are not capable of operating independently from the mother vessel. Submarines are…

Quantum Computers.

These are futuristic computers. This because the technology behind these computers are in the testing phase and so have not yet been deployed for real time applications. These computers are said to solve mathematical problems many times faster than any supercomputer being used anywhere in the world. To put it in context, Google says it…

Nuclear Powered Ships.

Nuclear power has been used for ship propulsion since the 1950s when the first nuclear powered submarine was launched. Since then numerous warships like cruisers and aircraft carriers have been built with nuclear propulsion in countries like the US, France,Russia, Britain. This propulsion system has the advantage of not requiring regular refueling as refueling is…

RoRo Ships

Roll on Roll off ships or RoRo ships are specifically built to carry wheeled vehicles such as cars, trucks,railroad cars etc which can be driven in and out of the ship as required. The cargo are stowed such that during pitching and rolling they do not move out of their original positions to collide with…

LNG/LPG Ships.

These ships are designed and constructed to carry natural gas or petrol gas in the liquified form. They are highly specialized vessels and require more technical skills and knowledge to construct these vessels. The vessels are built with flush decks and the superstructure built aft of the ship. The superstructure hosts the bridge and accommodation…

Cargo Ships

Cargo ships are used for transporting cargo in large quantity from one seaport to another. They are large vessels usually from 40000 tons and above. They are constructed with compartments to hold cargo such as iron ore, coal, rice etc. Their propulsion system is diesel engines which are usually two- stroke engines.Two stroke engines consist…
