India Needs 1.3 to 1.5 Billion Tonnes of Coal by 2030

  Due consultations were held for finalizing India's approach for negotiations at COP 21 and prior to signing the Paris Agreement.   As per Economic Survey, the demand for coal is expected to remain in the range of 1.3-1.5 billion tonnes by 2030. Coal is the most important and abundant fossil fuel in India and accounts for 55% of the country's energy need. Commercial primary energy consumption in India has grown by about 700% in the last four decades. The current per capita commercial primary energy consumption in India is about 350 kgoe/year. Coal is not only the primary source of energy in the country but is also used as an intermediary by many industries such as steel, sponge iron, cement, paper, brick-kilns etc. Similarly, with increase in growth of industries using coal, their demand for coal has also been increasing; hence, there has been an overall increase in the demand of coal over the years. Being an affordable source of energy with substantial reserve, coal is going

IIT Ropar develops first-of-its-kind Oxygen rationing device

 To increase the life of medical oxygen cylinders three fold, the Indian Institute of Technology, Ropar has developed a first-of-its-kind Oxygen Rationing Device – AMLEX that supplies a required volume of oxygen to the patient during inhalation and trips when the patient exhales CO2. This process saves oxygen which otherwise unnecessarily get wasted.

So far, during exhalation, the oxygen in the oxygen cylinder/pipe is pushed out along with the exhaled CO2 by the user. This leads to wastage of a large volume of oxygen in long run. In addition to this, a large volume of oxygen escapes from the openings of the mask to the environment in the resting period (between inhalation and exhalation) due to continuous flow of life saving gas in the mask. As we have seen the demand of medical oxygen has jumped manifold amid the second wave of Covid-19, the device would help in stopping the unwanted wastage of the same. 

“The device can operate on both portable power supply (battery) as well as line supply (220V-50Hz)”, said Director, IIT, Ropar, Prof. Rajeev Ahuja.

 

It has been developed by PhD students of Biomedical Engineering Department of the institution - Mohit Kumar, Ravinder Kumar and Amanpreet Chander under the guidance of Dr. Ashish Sahani, Assistant Professor, Department of Biomedical Engineering.

 

“Made specifically for oxygen cylinders, AMLEX can be easily connected between oxygen supply line and the mask worn by the patient. It uses a sensor which senses and successfully detects inhalation and exhalation of the user in any environmental condition”, said Dr Sahani. This ready to use device works with any commercially available oxygen therapy masks having multiple openings for air flow. 

 

Appreciating the innovation, Dr GS Wander, Director, Research and Development at Dayanand Medical College, Ludhiana, said that in the present pandemic times we all have learnt the importance of effective and pertinent use of life saving Oxygen. He said though many hospitals are increasing their oxygen production capacity, a device like this can really help in limiting the use of oxygen in small rural and semi urban health centers.

 

Prof. Rajeev Ahuja said that the country now needs rapid but safe solutions to combat Covid-19. Since the virus is affecting the lungs and subsequently breathing system of the patient, the institution has not intended to go in for patenting of the device. He said rather the IIT would be happy to transfer this technology free of cost, in the interest of the nation, to those interested to go in for mass production of the device.
