** IIT-M researchers develop zinc-air batteries

It is an alternative to lithium-ion batteries for electric vehicles

Researchers at the Indian Institute of Technology Madras are developing mechanically rechargeable zinc-air batteries as an alternative to lithium-ion batteries to power electric vehicles (EV). They have filed for patents for their technology and are collaborating with major industries to develop the batteries.

As zinc-air batteries are economical and have longer shelf-life, they can be used in two and three-wheel EVs, the researchers say.

Aravind Kumar Chandiran, assistant professor in the Chemical Engineering Department at the Institute, and his team is working on zinc-air batteries as zinc is a widely available resource in the country. Currently India imports lithium-ion batteries from China. “Our research team is developing a futuristic model for zinc-air batteries for EVs. The team has developed zinc-air cells and is working to develop zinc-air packs for EVs,” he said

** Learn about India’s biodiversity from this card game created by Chennai students

A new game developed by Chennai students spreads awareness about different ecosystems, species and what we can do to help them

Can a game of cards increase environmental awareness? A group of educators and students seem to think so. Having worked for five months on a project by city-based Palluyir Trust, they now present The Wilderness game.

The game is essentially a pack of cards — think cricket or wrestling cards — but with sea creatures instead of The Undertaker, and a flood of real-world information thrown in. Environmentalist M Yuvan and Chennai students Nanditha Ramsatagopan, Charlotte Jeffries and Rohit Srinivasan, designed it for people above the age of 10. The gameplay format keeps in mind millennial and Gen-Z mindsets.

** Women make their families proud as they march out of the Indian Naval Academy as officers

What makes the likes of Brahmjot Kaur tick? She holds a B.Tech degree in Electronics and Communications and could have opted for a job in the private sector. Yet, it was that attraction for the uniform that prevailed. On Saturday, she was one of 30 women who marched out of the Indian Naval Academy in Ezhimala, Kerala, as a sub lieutenant of the Indian Navy.

“It is great that the number of women opting for the Navy as a career is going up. As it is, the Navy has the largest percentage (6.2 per cent) of women officers among the three armed forces in the country. In the batch that passed out on Saturday, there were 210 men and 30 women. That means that this batch had 12.5 per cent women. We also have women pilots serving on ships now,” a senior naval officer said.

While Brahmjot is from the Naval Armament Inspectorate Cadre (NAIC), there are other women in her batch who will go on to become logistics officers, law officers, observers and naval constructors after further training at other bases. The last 5-odd months at Ezhimala have been gruelling, Brahmjot says but she is ready for more.

Her grandfather is Wing Commander Swarn Singh Birdi (retd) and her father is Group Captain Simranpal Singh Birdi. Her maternal grandfather is Lt Col K.S. Cheema (retd).

** 1946 Last War of Independence Royal Indian Navy Mutiny review: The 1946 naval uprising

Pramod Kapoor transforms a footnote in history into a remarkable account of a rebellion that convinced the British it was time to leave India

As rightly remarked by Shyam Benegal, a footnote in the history of the freedom movement has been turned into an exciting and important account in Pramod Kapoor’s  1946 Last War of Independence: Royal Indian Navy Mutiny. Pramod himself stumbled onto this forgotten story while researching for his book on Gandhi: “After the draft of the Gandhi book was done, I re-read the Royal Indian Navy mutiny episodes and realised the magnitude of the event.”

Reports of the revolt

When Pramod began his research, he discovered hundreds of reports by British admirals, commanding officers of ships and shore establishments, cables and letters exchanged between London and Delhi, proceedings in the British parliament and debates in the Legislative Council in India. They were “honest,” but were told from the British point of view. For another view, Pramod waded through hundreds of newspaper reports and documents at libraries, met people with knowledge of the revolt and toured HMIS Talwar, the signal school of the Navy at Colaba, where “inflammatory slogans” had been written on the walls and “seditious pamphlets” were circulated. A tour of the dockyard and areas of Navy Nagar in Mumbai helped him understand the “history and geography of the area where the uprising took place.”

In February 1946, ratings, or the lowest rung of sailors in the Royal Indian Navy hierarchy, staged a revolt. The young sailors were protesting against the fact that things they were promised at the time of recruitment had not been honoured: living conditions were horrible; the food worse and there was rampant racial discrimination. Also, says Pramod, inspired by the Indian National Army (INA), they were politically charged and keen to play a part in India’s freedom movement. Within 48 hours, the strength of the mutineers grew to 20,000, and they took over ships afloat and on-shore establishments. Servicemen in the army and air force, and civilians joined the protests.

** VVCE students design low-cost cooling solution to keep fruits and vegetables fresh

The model requires the vendors to charge it once in a day at home

A low-cost cooling solution harnessing solar power to help vegetable vendors in keeping the perishable produce fresh has been designed by four students of Vidyavardhaka College of Engineering in Mysuru.

H.V.Naveen, Shubham Sain, S.Supreeth and Vivek Chandrashekar who took up the project are students of Mechanical Engineering branch and are in the sixth semester. The project addresses one of the major problems that vegetable vendors face every day: that of keeping the vegetables fresh when they are out in the market selling it under the scorching sun.

The students have designed the cart in such a way that the refrigeration of the cart can be maintained in a temperature range between 0 degree C and 10 degree C. Generally, a temperature in the range of 5 degree C to 10 degree C is required to keep the vegetables fresh. But the students have gone a step ahead and have extended the utility of the cart to help those selling diary products as well.
