Short Distance Trains

These trains usually run between city centres and suburban areas providing services to a huge population which would have been difficult for cars and other means of transport. Short distance trains include; commuter trains, rapid transit trains, trams, light rail, monorail, mine trains, magnetic levitation trains, railcar, heritage trains. Commuter Trains. These trains are used…

Intercity Trains

Intercity trains are trains that are utilized within cities and provide fast train services with limited stops over long distances. These trains are categorized into three types; intercity, express, regional. Intercity: It uses high speed trains to connect cities while bypassing all intermediate stops thus linking major population hubs in the shortest time possible. Express:…

High Speed Trains.

These type of trains are becoming more popular especially for travel within countries with vast distances between cities. High speed trains usually operate at speeds exceeding 200km/ hr with trains such as the TGV in France exceeding speeds of 300 km/ hr. The first example of a commercially successful high speed train was Japan’s Shinkansen…

Long Distance Trains.

Long distance trains travel between cities or regions within a country, or from one country to another. They are usually long trains, with coaches designed as restaurants to provide catering services to passengers embarking on the journey. There are also sleeping coaches and facilities such as bathrooms and toilets for the passengers. They are also…

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….

Trains.

Trains are a series of connected cars running on rail tracks. The tracks are made of iron resting on concrete bars laid on the ground continuously over long distances. Trains are used to transport cargo and passengers over long distances and difficult terrain. Most trains are powered by diesel electric engines, but can also be…

Osmotic Power Station

Osmotic power is the energy available from the difference in the salt concentration between seawater and river water. Two practical methods used are reverse electrodialysis and pressure retarded osmosis. Both processes rely on osmosis with membranes. The key waste product is brackish water. The technology of generating electricity by osmotic method was invented in 1973….

Biomass Power Plants

Biomass is fuel derived from organic materials, a renewable and sustainable source of energy used to create electricity. Some examples of biomass fuels include; forest debris, scrap lumber, crops such as sugar cane, manure, waste residue. With a constant supply of waste from construction and demolition activities to wood not used in paper making to…

Hydro Electric Power Plants

Hydro electric power plants utilize water in huge reservoirs to generate electricity. A dam is usually built across a body of water, creating a reservoir behind it. The dam is built with huge turbines located inside the dam. Outlets are created for the water from the reservoir to flow to the other side of the…

Solar Power Plants

Solar power is the conversion of energy from the sun to electricity. The process involves the use of photovoltaics or concentrated solar power or both. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic cells convert light to an electric current…

Nuclear Power Plants

A nuclear power plant is a thermal station whose heat source is a nuclear reactor. As with thermal stations, the heat generated is used to produce steam which is used to drive a turbine. The turbine is connected to a generator which produces electricity. As the turbine rotates, it drives the generator that produces electricity….

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…

Geothermal power plants

These plants generate electrical power using geothermal energy. The plant types include; Dry steam power stations, flash steam power stations and binary cycle power stations. This electric generation type is currently used in 26 countries. Statistics show that worldwide generation capacity of geothermal plants amount to 12.8 gigawatts and projected to reach 18 gigawatts by…

Coal fired power plants.

Coal fired power plants utilize coal to generate electricity. They are the most commonly used of all power plant types.
