HYPERLOOP ONE – The Future of Travelling

Ever thought about traveling Kottayam to Kochi in just 5 minutes? Well, it could be possible if we apply the concept of Hyperloop one.

We live in an Era where time is money, money that we lose and won't get back ever again. Hyperloop one focuses on effective travelling across cities.
Following a motto of “Be Anywhere, Move Everything, Connect everyone “, Hyperloop one achieves the vision of travelling in the future.

Hyperloop One is the beginning of a new way to move people and things at airline speeds for the price of a bus ticket. It's on-demand, energy-efficient and safe. Just as simple as the broadband for transportation.

They use a custom electric motor in order to accelerate and decelerate a levitated pod through a low-pressurized tube. The vehicle will glide silently for miles with absolutely no turbulence.

All this, is happening faster than you think. Hyperloop one tested their motor in May, 2016, and will test their full system in early 2017 (Abu Dhabi to Dubai, 160km in just 12 minutes).

The world is ready for a new mode of transportation that will change the way we live, we thrive, we think. Hyperloop one is in the business of selling time, the most precious resource there is. When cities become metro stops, regions will indeed flourish.

Look outside the window for the future is here.

Humanity's First Space Nation: ASGARDIA

Science and technology is moving at a rapid pace that's why a multinational group of researches, scientists, engineers and other experts revealed their plans for an independent space nation named ASGARDIA after the city in the skies from Norse mythology. This nation will provide a place free from land based country laws, or it can be considered as a no man's land. The initial step is to launch a robotic satellite in 2017 and then follow up with permanent space station where Asgardian citizens can live and work.

Asgardia's technical structure is comprised of three segments:
1- One or several core satellites
2- Clusters of network-centric small satellites
3- Protective space platform

The founder of Asgardia is Dr. Igor Ashurbeyli. The concept was presented at press conference in Paris on 17 October 2016. The project received more than 400000 applications in just one week from its announcement. Asgardia is a unique for of  philosophical aspect which serves every citizen equally regardless of their country, ethnicity, or other personal welfare. 
"The new space nation of Asgardia hopes to save the human race twice over. First, it will look to protect it from warfare in space and second, it will try to keep humanity safe from the dangers coming from outside of atmosphere, protecting us from threats like space debris and asteroid collisions''

Does anything violates the LAWS OF PHYSICS??

Does anything violates the laws of physics? Yes.. an EmDRIVE WILL.

Newtons Third Law states that for every action there is an equal and opposite reaction. But what violates it is a propulsion system in the EmDrive which is the reason for the controversy. It is developed by British researcher Roger Shawyer in the early 2000s.

Before getting into EmDrive, we can see how a propulsion system generates thrust. A propulsion system generates thrust by blasting propellant in one direction and thereby moving the craft in the opposite direction. For instance a rocket generates thrust by shooting super heated gas under high pressure to produce a kinetic energy greater than Earth's binding energy. This happens on the basis of Newtons Third Law, i.e. an action of shooting hot gas is the cause of the reaction, which is the thrust. 

But what happens in an EmDrive (electro magnetic) is that instead of blasting propellant it radiates microwaves around a cone shaped chamber. There is no exhaust so that there doesn't appear anything that can generate the thrust. Apart from that NASA researchers found that the EmDrive which they tested  produced a thrust of 1.2 milli newton force per kilowatt ina the lab.

According to Shawyer it can be used in spacecrafts and also power flying cars. Lets hope for a better future with flying cars...!

V2V Communication

Vehicles talking to each other!
In February, US National Highway Traffic Safety Administration have announced that it will begin taking steps to enable vehicle-to-vehicle (V2V) communication technology for light vehicles.

This technology would allow vehicles to "talk" to each other and ultimately avoid many crashes altogether by exchanging basic safety data, such as speed and position, ten times per second, to improve safety. It uses 'ad hoc network', where every car is free to associate with any other car available in the network and share equal status. V2V, which is also known as VANET (vehicular ad hoc network), is a variation of MANET(mobile ad hoc network). 

Many automobile manufacturers including are BMW, Audi, Honda, General Motors, Volvo and Daimler working and developing this technology to improve safety, overcome blind spots and avoid accidents.

The How v/s Why of Engineering

From the viewpoint of a common man, there are certain perceptions about an engineer. For example, every Mechanical Engineer is expected to know how to repair a bike or car. An Electronics Engineer must be an expert in fixing the problems in a device like television, computer or a switchboard. Most often Engineering Students are also expected to be the ‘repairers’ when there is a technical problem.

But is it the sole skill expected of an engineer? The real question is: What is the question to be answered by an engineer? The HOW question or the WHY question.
Confusing, huh?

The HOW Question: Have a look at some of the HOW questions.
How to tighten a screw? How to solder or join an electrical component? How to do the welded joint? How to cut a metal sheet?

These are practical questions with an answer available from thumb rules and experience. Answers that can be obtained from a trained person, who may not necessarily know the details of the science behind it.

The real question to which an engineer should answer is the WHY Question.

The WHY question:
Why is High Speed Steel used for drilling? Why is Aluminium difficult to weld? Why did that machine stop working? Why should there be a high factor of safety given while constructing complex structures?

The WHY question can be answered only by a well-educated and skilled Engineer. The knowledge of theory and its application is the foundation of an Engineer. To nourish the real engineer in you, start asking ‘Why’, more than asking ‘How’.

Start asking Why and find answers.

The Chinese TEB

A Bus running over a car! Oh, that seems to be impractical, how can it happen?  Even if it is there, how hazardous it would be? Obviously these questions would arise in every people. However, the Chinese brains have practically found an answer to these questions.
High population, pollution and energy requirement is challenging China in their growth as an economic monopoly. In fact, they are seeking many scientific applications as the solution to these problems. Among them the most recent and the vibrant one is the Transit Elevated Bus (TEB).

China is topping as the world’s most populated country. It also tops for the vehicular population too. This is creating large losses to the country as it leads to the depletion of energy resources and also leads to pollution.  In order to control the problem they increased the number of road lanes and their width. But on the go, they realized that it will not be a good solution to the problem. And now they have come up with a new sensational solution, the TEB.

Instead of adding more lanes to widen the road, what about doing more lanes above the road? That’s the idea behind the Transit Elevated Bus .The TEB travels above car traffic, with the wheels of the bus hitting the ground on the outer edges of the car lanes.
Test Run of  TEB

A test version of the TEB hit the road in Qinhuangdao City on August 2, 2016. The bus which is designed to ease traffic congestion, is a massive structure. It stretches just over 72 feet in length, over 25 feet in width, and almost 16 feet above road level. The TEB is powered by electricity and can carry 300 passengers. Although August 2016 saw TEB in its phase, the developers are hoping the bus will reach maximum speeds of 40 mph when it hits the road for mainstream use.
In a closer watch we can infer that this project is practical to a great extent, and it is advantageous over many other alternatives. Any way the initial installation cost would be a huge sum but it would not be a problem for Chinese Economy. Other countries should seek the help of skilled engineers to implement this technology in their country at a low cost. The zero pollution concept also adds to the advantages of this bus.

About BRAHMOS - India's pride

BRAHMOS, the first supersonic cruise missile in our world, is named from the two rivers (BRAHMaputra of India and MOSkava of Russia).These missile are developed by DRDO (defence research and development organisation) with help of Russia and are similar to sea-skimming Russian cruise missile technology. 

It has a two stage propulsion system, with solid propellant responsible for initial acceleration and liquid fuelled ramjet for responsible for sustainable supersonic trust production. It can attack surface targets by flying from 5 m to 14000 m height. It has 70 cm diameter. It is a far better cruise missile than Tomahawk (created by USA), because it can attack the target efficiently and 32 times speed than tomahawk. These missiles are launched from sea and land.

Indian and Russian governments have decided to create 2000 missiles over 10 years. In Future Indian Government will be export these missiles to countries like Bhutan, Bangladesh, Vietnam. These missiles are of great strategic importance to India. In 2016 India joins MTCR (Missile Technology Control Regime). Also, Russia and India are develop to create new generation missile and able to hit target with accurately. BRAHMOS II and BRAHMOS - NG are examples of these type of cruise missiles.
