In a possible hate crime, an Indian woman IT consultant working with tech firm MindTree was stabbed to death at Sydney in Australia today.
Identified as Prabha Arun, the victim was attacked at Amos Street in the western part of Sydney. Police found Prabha “seriously wounded” and took her to the Westmead Hospital where she later died, The Sydney Morning Herald reported.
The attack happened near a cluster of trees with wide open spaces on either side and was 20 metres from the nearest light, media reports said.
The external affairs ministry spokesperson in New Delhi tweeted that the Consulate General of India in Sydney was aware of the incident. “All necessary assistance is being provided,” the spokesperson said.
Police are scanning the CCTV footage of her walking from the station along Argyle Street and on to Park Parade to see if there was anyone following her into Parramatta Park.
As the pre-monsoon summer heat takes hold in New Delhi, two things are as inevitable as 40-degree-Celsius days: power cuts and air pollution from the diesel generators that then kick in.
But a team of Indian engineers has figured out away to bring some good from choking generator exhaust: They are capturing it and turning it into ink.
“The alarming thing about diesel generators is they are located in the heart of densely populated areas. It’s spitting smoke right there,” said Kushagra Srivastava, one of the three engineers who developed the technology, now installed in Gurgaon, a satellite city of New Delhi, and in the southern city of Chennai.
The idea, Srivastava said, came about when he and his co-founders stopped at a sugarcane juice stall on a hot day.
They noticed a wall that had turned black behind the stand’s diesel generator, where exhaust emerged from a pipe.
They wondered if diesel exhaust might be used to produce paint — and set out to try.
The device they came up with, which attaches to generators, captures 90 percent of the soot particles from cooled diesel exhaust. The material can then be sold to ink manufacturers.
Their company, Chakr Innovation, has so far installed 50 of the devices for government firms such as Indian Oil, real estate developers and other state government offices, earning more than 11 million rupees ($200,000) in revenue in the first year, Srivastava said.
The company has plans to install another 50 devices over the coming year, he said. It has so far sold 500 kg of collected soot, which has been used to create 20,000 liters of ink, he added.
Chakr Innovations is not the first start-up to see cash in diesel exhaust. A competitor called Graviky Labs, based in Bangalore, is using similar technology to turn diesel exhaust from vehicles into ink.
Srivastava and his co-inventors Arpit Dhupar and Prateek Sachan see themselves as part of a movement towards cleaner air and energy in a country where major cities struggle with choking air.
About 1.1 million people a year die from the impacts of air pollution in India, according to a 2015 survey by the U.S.-based Health Effects Institute. That is about a quarter of the total number of air pollution deaths worldwide, it said.
In New Delhi, levels of the most dangerous particles in the air are sometimes 10 times higher than the safe limit, the survey noted.
Srivastava and Dhupar both grew up in New Delhi, which the World Health Organization in 2014 declared the most polluted city in the world. Sachan comes from Allahabad, the third most polluted city in WHO’s 2016 rankings.
“Earlier I remember there were a lot less cars on the road, there was a lot less congestion, and a lot more greenery,” said Dhupar, Chakr’s chief technology officer.
But as trees were felled and roads widened to accommodate more cars, Dhupar — then in high school — developed chronic respiratory problems. Doctors put him on medication and warned him to stop playing sports.
“My problem is, whenever I start to run out of air, the anxiety levels shoot up,” he said.
Dhupar said many of his family and friends have also developed long-term respiratory issues.
Diesel exhaust contributed to just 2 percent of all air pollution deaths in India in 2015, according to the Health Effects Institute.
But in “confined spaces” in urban areas, where many generators are used, it represents a larger risk, said Pankaj Sadavarte, one of the report’s researchers.
Action in New Delhi
India has in place policies to monitor and restrict air pollution, but they can be difficult to enforce, experts say.
Worries about air pollution are growing, however. Last November, the capital launched its first air quality emergency action plan during a particularly hazardous week when pollution spiked.
The government halted construction within the city, raised parking fees to discourage driving and shut schools to keep children indoors.
The national Ministry of Environment, Forest and Climate Change is drafting a national policy to clean India’s air, though its release has been delayed, said Sunil Dahiya, a senior campaigner with Greenpeace India.
“The air pollution debate and health debate is picking up in India,” Dahiya said in a telephone interview. “That momentum is forcing the policymakers to make our cities more livable.” (VOA)
