Atmospheric Water Generator

Navratna Defence PSU Bharat Electronics Ltd (BEL) has unveiled its new product, the Atmospheric Water Generator (AWG), an innovative solution to meet the ever-increasing need for drinking water worldwide,at Aero India 2019.

Highlights:

  • BEL’s Atmospheric Water Generator can be used to generate water straight from the humidity present in the atmosphere.
  • BEL’s Atmospheric Water Generator employs a novel technology to extract water from the humidity present in the atmosphere and purify it.

How does it works?

  • It uses heat exchange for condensing the atmospheric moisture to produce pure, safe and clean potable water.
  • The AWG comes with a Mineralisation Unit, which is used to add minerals which are required to make the water potable.
  • The AWG is configurable in static and mobile (vehicular) versions and is available in 30 litres/day, 100 litres/day, 500 litres/day and 1,000 litres/day capacities.

Significance:

The Atmospheric Water Generator can be used to provide drinking water in community centres and public places like health care centres, schools, colleges, offices, railway stations, bus stands, airports, sea ports, off-shore oil rigs, military establishments, remote field areas and remote establishments and residential complexes.

Waste to Wonder Park

The “Waste to Wonder” Park under the South Delhi Municipal Corporation (SDMC).

Highlights:

  • The park features replicas of seven wonders of the world. The replicas have been made using 150 tonnes of scrap material.
  • The efforts should be made towards behavioural change of the people and proper arrangement should be made for waste disposal.
  • A system should be developed for recycling of waste that can be reused.
  • The products which cannot be recycled should be minimally used.

Digital Bharat, Saksham Bharat -A Compendium on Digital India

A Digital India Compendium on Digital Bharat, Saksham Bharat was released recently.

Highlights:

  • The objective of the document is to disseminate and propagate the success of Digital India among masses.
  • The document is divided in two sections-
  1. Digital profile of India- It comprises a in-depth analysis, comparative study of implementation of Digital India Programme and transformation it has brought out in the lives of citizens. It has simplified the way citizens avail various Government services and has brought transparency and accountability.
  2. Digital profile of States & UTs- It reflects the State/ UT wise implementation of various initiatives taken under Digital India Programme.
  • The document emphasizes Digital India initiatives that aim to transform India into a knowledge-based economy and digitally empowered society by ensuring digital access, digital inclusion, digital empowerment and bridging the digital divide.

Param Shivay-supercomputer

The ‘Param Shivay’ Supercomputer of 833 teraflop capacity built at the cost of Rs 32.5 crore under the National Super Computing Mission at the Indian Institute of Technology (IIT), Banaras Hindu University (BHU) was recently inaugurated.

About Param Shivay:

  • The ‘Param Shivay’ will include 1 peta byte secondary storage and appropriate open source system and application software suite using 223 processor nodes, 384 GB per node DDR4 RAM, parallel file system, including CPU and GPU.
  • India’s first supercomputer called PARAM 8000 was launched in 1991.

Benefits:

  • The problems of common man related to relevant social issues such as irrigation schemes, traffic management, health, an affordable drug will also be taken care of with this supercomputer centre, claims the institute.
  • Scientists, teachers and research students, government research laboratories in adjacent engineering colleges to IIT-BHU can avail benefits of the projects.

Topic 5: Material Science

Nanotech to help make affordable, non-polluting cars

Scientists have developed a new method of increasing the reactivity of ultrathin nanosheets, just a few atoms thick, an advance that can make fuel cells for hydrogen cars cheaper in the future.

Highlights:

  • The research offers promise towards faster, cheaper production of electrical power using fuel cells, and also of bulk chemicals and materials such as hydrogen.

How does it work?

  • The strain is, in short, the deformation of any material. For example, when a piece of paper is bent, it is effectively disrupted at the smallest, atomic level; the intricate lattices that hold the paper together are forever changed. Scientists  manipulated the strain effect, or distance between atoms, causing the material to change dramatically.
  • By making those lattices incredibly thin, roughly a million times thinner than a strand of human hair, the material becomes much easier to manipulate just like how one piece of paper is easier to bend than a thicker stack of paper.
  • By using force to tune the properties of thin metal sheets that make up electrocatalysts, which are part of the electrodes of fuel cells.

Benefits:

  • Fuel cells can reduce cost and clear the way for widespread adoption of green, renewable energy.
  • Researchers estimate that their new method can increase catalyst activity by 10 to 20 times, using 90 per cent less of precious metals than what is currently required to power a fuel cell.
  • To make environmentally-friendly cars more accessible for everybody.
