Maglev trains are one of the greatest inventions in man-made history. These trains float over the track using magnetic power. The name Maglev is an abbreviation of Mag netic Lev itation. As there is no contact between the train and the track, these type of trains moves faster with minimum energy loss. These trains are also well known for their eco-friendly operation, as it does not use any petroleum products like petrol, diesel, etc. From the year 1902, magnetic levitation has begun to rule the world. In 1984, the first commercial maglev train was introduced in Birmingham, the UK, with levitation of 15mm and a track length of 600m. From the past to the present, there were several breakthroughs made in maglev technology. These breakthroughs were successfully implemented at present in three countries; namely China, South K...
An engine is a machine that converts one form of energy into mechanical energy. Heat engines particularly used in vehicles, use chemical fuel to produce mechanical energy. In heat engines, the fuel is burnt and the resultant steam provided, is used to cause a rotating motion. These heat engines are classified into 1. Internal combustion Engine 2. External Combustion Engine Credit (Internal Combustion Engine): By MichaelFrey - Own work, CC BY-SA 4.0, https://commons.wikimedia.org/w/index.php?curid=41646424 External Combustion Engine An internal combustion engine burns the fuel within it and uses the developed steam to produce mechanical energy. Whereas in an external combustion engine, the fuel is burnt in a separate chamber and the generated steam is carried out through a pipe and then fed to the engine to produce mechanical energy. The interna...
Jet streams are fast-flowing winds that circulate over the globe at a higher atmosphere. It is the part of global air circulation situated over the tropopause. Global air circulations are one of the primary things established under three cell categories to redistribute the heat all over the globe. Jet streams are formed during these redistributions. The major jet streams that form via the global air circulation are subtropical jet streams and polar jet streams. The subtropical jet stream originates at the subtropical region, and the polar jet stream originates at the subpolar region. These jet streams are permanent winds that exist in both the northern and the southern hemispheres, and flow around the globe all around the year.
