Top 5 Engineering Marvels of the Modern World


Innovation is what fosters development in science and technology – to make people’s lives better.

 Here are some of the top engineering marvels of the modern world:
  1. 3D printers (mechanical engineering)

A 3D printer, as it name implies, prints three-dimensional objects while being guided by a computer. 3D printers have come in trend as companies have been implementing it to print/produce complex/intricate parts of their overall product to reduce production cost.
As 3D printers use electronic data source to print 3-D models, objects of almost any shape or geometry can be printed. Just like conventional 2D printers, 3-D printers use ink jets to shape the object (intended to be printed) layer by layer.
  1. Smart grid (electrical engineering)

A smart grid is an electrical grid which comprises of a variety of operational measures including Energy efficient resources, renewable energy resources, Smart appliances, and smart meters.
The most important aspects of a smart grid include distribution of electricity, and electronic power conditioning and control of the production.
India is one of those countries which is steadily venturing into renewable energy sources such as solar and wind energy. As these renewable energy resources are unpredictable energy sources, it is important to have an efficient grid that is highly adaptive. And as a good electrical supply is one of the fundamentals to support overall development, India strives to implement smart grids in regions that are economically viable.
  1. Origami-inspired robots (electronic engineering)

The realm of small-scale robots is taking a whole new turn as folding/origami-inspired robots are being developed. Conventional small-scale robots require bulky batteries for power which limit their functionality. But this is not the case with origami-inspired robots as they do not require any battery.
Instead, they are controlled by a wireless magnetic field. These robots are being developed to make them commercially viable. Their success can make a great impact in medical science and other industries that involve precision.
  1. Burj Khalifa (civil engineering)

Burj Khalifa is a modern architectural marvel as it is the tallest building in the world as it stands at a height of 2,717 ft. Burj Khalifa is an engineering feat and doesn't seem to have a peer when it comes to concept and execution.
The construction work of Burj Khalifa began in 2004, took five years to complete, and was opened in 2010. The main objective behind the Dubai government's execution to construct the building was to diversify from an oil based economy.
  1. Palm Islands (civil engineering)

Palm islands are three man-made islands (including Palm Jumeirah, Palm Jebel Ali, and Deira Island) on the coast of Dubai. Amongst these three artificial islands, Palm Jumeirah has been completed.
The shape of the island resembles a palm tree, with a crescent on the top. Palm Jebel Ali has also been designed to take a similar shape. The Palm Jumeirah hosts residencies, hotels, and resorts.
