Mechanical Transmission vs Electrical Transmission.
This is how there is reduction in the weight, cost, losses and eventually increase in efficiency of Electrical Vehicles (DC or Induction Motors) as compared to those with mechanical generation of torque (IC Engine) transmission of power to the wheels through the gear and clutch mechanisms unlike electrical vehicles where the motors are directly coupled to the shaft via just one gear pair and the speed control is done by leveraging Power Electronics technology.

Latest Transportation Technology faster than the speed of sound!
===================================================
The Hyperloop is a conceptual high-speed transportation system put forward by entrepreneur Elon Musk(CEO Tesla Motors and SpaceX), incorporating reduced-pressure tubes in which pressurized capsules ride on an air cushion driven by linear induction motors and air compressors. The first of the routes which is proposed is between Los Angeles and San Francisco in the State of California, US. The distance between them which is about 570 km would be traversed in a time of just 35 minutes with the capsule having speeds as high as 962 km/h and top speed attained would be 1220 km/h. Considering the same in Indian context it would like living in Mumbai and working in Delhi that too just a total 2 hour to and fro commute or vice versa.
Looking at energy efficieny part of the system the tube would also be mounted with solar panals to harness as much solar energy as possible
A company called Hyperloop Transportation Technologies is already working on it in California to construct a 5 mile test track. There is alot of testing, analysis and improvements yet to be done on this still developing and not much known technology to get well acaquainted with it's effects on the human body (large acceleration) and with other factors which affect it's performance.
Also, the technological and economic feasibility of the idea is unproven and a subject of significant debate.

André-Marie Ampère (20 January 1775 – 10 June 1836) was a French physicist and mathematician who was one of the founders of the science of classical electromagnetism, which he referred to as "electrodynamics". The SI unit of measurement of electric current, the ampere, is named after him.
In September 1820, Ampère’s friend and eventual eulogist François Arago showed the members of the French Academy of Sciences the surprising discovery of Danish physicist Hans Christian Ørsted that a magnetic needle is deflected by an adjacent electric current. Ampère began developing a mathematical and physical theory to understand the relationship between electricity and magnetism. Furthering Ørsted’s experimental work, Ampère showed that two parallel wires carrying electric currents attract or repel each other, depending on whether the currents flow in the same or opposite directions, respectively - this laid the foundation of electrodynamics. He also applied mathematics in generalizing physical laws from these experimental results. The most important of these was the principle that came to be called Ampère’s law, which states that the mutual action of two lengths of current-carrying wire is proportional to their lengths and to the intensities of their currents and also the Ampere's Circuital Law which states "the line integral of Magnetic Field Intensity along a closed path gives the total current through that path".

So we look at another phenomenon related to electrical and magnetic fields which is called Hall effect.
If an electric current flows through a conductor in a magnetic field, the magnetic field exerts a transverse force on the moving charge carriers which tends to push them to one side of the conductor. This is most evident in a thin flat conductor as illustrated. A buildup of charge at the sides of the conductors will balance this magnetic influence, producing a measurable voltage between the two sides of the conductor. The presence of this measurable transverse voltage is called the Hall effect after E. H. Hall who discovered it in 1879.
Applications include position sensing, speed sensing, level indication, current sensing and many more.
Hall Effect Sensors also form a part of sensors which make up the IoT (Internet of Things)

The history of Electricity dates back to around 585 BC, Thales discovered that if he rubbed amber (ilektron) with a piece of fur, that amber could attract lightweight objects (like feathers) to itself. Thales had discovered the principle of static electricity. Moreover particularly Electrical Engineering can be dated back to the 17th century. So we take tour about how the developments, discoveries and inventions lead to the development of such a field which now is indispensable and as a result ubiquitous. We remember the people who have played pivotal role in this journey of electricity, in our series "Remembering Them". First of all we have Volta, in whose honor is the unit of voltage i.e. Volt.

Alessandro Volta was an Italian physicist, chemist, and a pioneer of electricity and power, who is credited as the inventor of the electrical battery and the discoverer of methane. He invented the Voltaic pile in 1799 and the results of which he reported in 1800 in a two-part letter to the President of the Royal Society.With this invention Volta proved that electricity could be generated chemically and debased the prevalent theory that electricity was generated solely by living beings. Volta's invention sparked a great amount of scientific excitement and led others to conduct similar experiments which eventually led to the development of the field of electrochemistry.

Back 2 Basics Our new series in which we start elucidating some basic electrical and electronics concepts and devices:
So,
We start with PN Junction Diodes which are the most basic circuit building blocks in Electronic Systems.
It is two terminal [ anode (A) and cathode (K) ] device with unidirectional flow property that is it allows current to flow only in one direction and blocks the current in opposite direction working in forward bias in the former and reverse bias in the later case. When A is at higher potential with respect to K, it is forward biased and reversed biased, when K is at higher potential with respect to A. In forward bias it only starts to conduct once positive voltage is more than 0.7V (Si diode). This basic characteristic can be used to control currents and voltages in many circuits and popular applications include rectifiers (AC to DC). For higher voltages in Transmission and Distribution System Level of voltages Power Diodes are used which work on the same principle as small signal diodes.
