But, did you know, that trains, can also reach the islands??
In this video we will show how a train is able to travel across the sea thanks to the aid of a...
What is a THYRISTOR and how it works - PN-PN junction

A Thyristor or SCR (Silicon Controlled Rectifier) is a semiconductor device that allows the flow of electric current only in one direction. It behaves like a diode, but unlike the latter, the pass-through current can be driven.

More than 10 years in industrial supply have led JAES to become a qualified partner for some of the most important thyrisyor manufacturer companies. ...
How Inverters Work - Working principle rectifier

We’re going to be looking at inverters: their uses and how they work, coming up.
First of all look at the difference between alternating and direct current, then we’ll look at the purpose of inverters and where they are used. Then we’ll move on and have a look at simple example of how they work and finally we’ll look at a more advanced pulse width modulation example.

How to produce hydrogen efficiently? Discovering the fuel of the future

Hydrogen is the most simple chemical element on earth. As a matter of fact, atoms are composed by a single proton and a single electron. That’s why hydrogen is the first element in the periodic table.
Many think wrongly that hydrogen is an energy source, however it actually is an ENERGY VECTOR, because it can accumulate and provide that energy. For example, this process happens with fuel cells, which generate...

Different types of engineering


Over the years, some people are world-known as great engineers because they have given us structures, solutions, methods that even nowadays we consider them as some brilliant innovations. If you think of the engineer Brunel who built the Great Western Railway in the United Kingdom, and still working today, or Archimedes recognized as the greatest of all classical engineers, with his screw pump also called the screw of Archimedes. ...
What is a diode and how it works - PN junction and 3D animation

The diode is a mainly resistive non-linear passive electronic component with two terminals, whose function is to allow the flow of electric current in one direction and virtually block it in the opposite one.

The two diode terminals are called ANODE and CATHODE. The electric current conventionally goes from the anode to the cathode following this direction. ...

What is really engineering?


Everybody has certainly seen huge buildings while driving, like a suspension bridge, and wondered “how can that bridge hold up? How has it been designed and built?”.

This is what engineering is for: a technical-scientific discipline, whose goal is to produce systems and solutions for technical and material requirements through...
Automatic Transmission vs Manual Transmissions – Epicyclic Gear Train - Dual-clutch - Continuously Variable

As we’ve already explained in our previous video a manual transmission consists mainly of a gear pair and a clutch.
While the traditional automatic transmission uses a planetary gear and a torque converter.

When we decide to buy a new car the question is always the same:...
How do Lithium-ion batteries work?

Rechargeable and lightweight, Lithium-ion batteries have changed our lives on the way we communicate, move and work. Let’s see how they were born and how they work.

These batteries have revolutionized the way of storing energy since the early nineties.

The real protagonist is LITHIUM, this metal is...
How do transistors work?

TRANSISTORS are semiconductor devices widely used both in analog and digital electronics.
They are at the basis of modern electronics and are essential for the control of many circuits or entire processors.

The CPU (Central Processing Unit) or main processor is the core of the Computers elaboration. Only this element is made up of about 5 million transistors in...
Pressure Transmitter

In this video we will explain the operation of the transmitter, a device used to convert physical quantities into readable data visualizations, a basic requirement in every technological field.

More than 10 years in industrial supplies sector have led JAES to become a qualified partner for some of the most important industrial automation companies, providing any kind of transmitters. ...
How do electric cars work?

An electric car is a vehicle that is propelled by one or more electric motors, using energy stored in rechargeable batteries.

The first electric car prototypes were built and introduced already 200 years ago, during the first half of the 19th century.
Thanks to the industrial revolutions, during those years many scientific discoveries and inventions were...
How do bearings work?
Types and durability calculation.


Bearings are used to reduce the friction between two objects that are in linear or circular motion against each other.

The first intuition came from Leonardo Da Vinci in his studies regarding friction.
But the first patent was filed only in 1794 by Philip Vaughan of Carmarthen. ...
How does a thermal power plant work?

A thermal power plant is a large-sized plant that turns the thermal energy into electric energy, using water as working fluid.
Thanks to their production of electricity we can turn on the lights and make all our household appliances work, so that we can take advantage of many comforts.

The first thermal power plant was built in New York in 1882,...
Solar energy and photovoltaic cells

Solar energy is the energy associated with solar radiation and it represents the primary source of energy on Earth.
The sun is the engine of life on earth, which gives us light and heat.
Its radiation, used by plants to grow, passes in the form of chemical energy to living organisms that eat plants, and to others such as humans who feed themselves with animals and plants. ...
How does a hydraulic and pneumatic cylinder work?

In this video, we will see the major differences between hydraulic and pneumatic cylinders, their functioning, and their applications in the industrial sector.

Before starting, it is essential to specify that there are differences between the single-acting cylinder and the double-acting one.
The single-acting cylinder can be ruled in...
What is an ENCODER - Linear and Rotary encoder - Incremental and Absolute encoder

An encoder is a communication device that controls the motion of an operating device.
Encoders are used to translate rotary or linear motion into a digital signal helping to determine the speed or position of a motor or other moving equipment.
Basically, an encoder acts as a measuring system for moving parts. ...
