Hyderabad, Oct 9: As India plans to give a robust push to promote use of electric vehicles, a top scientist says hydrogen-based system would be the right choice in the long run given its potential to become fuelof the next generation.

The Indian Space Research Organisation (ISRO) had come out with a demonstration vehicle using hydrogen itself as fuel, G Madhavan Nair, the former chairman of the space agency, said.

He was referring to a hydrogen-powered bus developed four years ago by Tata Motors and ISRO after several years of research.

"In the long run, I will say that hydrogen-based thing will be the right choice because hydrogen has to become the fuel of the next generation," Nair told PTI in an interview.

India is looking at having an all-electric car fleet by 2030 with an express objective of lowering the fuel import bill and the running cost of vehicles. The government is aggressively trying to push the sales and production of EVs in the country through schemes such as FAME India.

State-run Energy Efficiency Services Ltd (EESL) last month said it will procure 10,000 electric cars.

According to Piyush Goyal, who held power portfolio till recently, India aims to become 100 per cent e-vehicle nation by 2030.

Union transport minister Nitin Gadkari has earlier asked automobile manufacturers in the country to go for eco-friendly alternative fuels, else he would 'bulldoze' them.

"We should move towards alternative fuel... I am going to do this, whether you like it or not. And I am not going to ask you. I will bulldoze it. For pollution, for imports, my ideas are crystal clear. The government has a crystal-clear policy to reduce imports and curb pollution," Gadkari said. Nair said the hydrogen fuel cell that directly powers vehicles is "pretty expensive these days" and, so, one has to evolve a low-cost fuel cells technology, to make them viable.

"And how to generate hydrogen in an economical way and then how to make fuel cells...these are some of the technology challenges. We should mount a research and development programme in this regard," he said.

He is of the view that disposing of lithium-ion batteries (LiBs) after use in EVs is going to be "tough".

"Lithium, you cannot throw it around. That becomes the most polluting thing. There has to be an adequate mechanism for collection and reprocessing," Nair said.

LiB has a life of five to seven years, which can be stretched up to 10 years, according to him.

"Disposals (therafter)...when you have millions of (electric) cars like this (LiB-operated)...they should not get caught in the normal way and pollute the environment," Nair said.

The availability of lithium is scarce and that's why the cost of LiBs is high, he said.

"Secondly, handling (lithium) is difficult, you require moisture-free environment.

That's why I say for the long-run, one should look for (Hydrogen) fuel cell which is something like a battery-sized box but does this conversion of hydrogen into electricity. If you invest on that, I think we will have a much better opportunity," Nair said. According to industry officials, hydrogen fuel-cell powered vehicles are "non-polluting", and water vapour is the only emission.

In such vehicles, hydrogen is stored in compressed form, which combines with oxygen in the air to generate electricity, which is used to charge the fuel cells to power their motor, they noted.

New delhi, Jun 22: As consumer sentiment runs high amid growing chorus for boycotting Chinese goods in the country, the fluid market situation offers new opportunities for various smartphone makers, especially the non-Chinese ones like Samsung, Apple, Nokia, Asus and others, to realign their strategies and regain the lost market share in the face of fierce Chinese competition.

The challenge here would be not to look "opportunistic" and leverage the current explosive situation on just riding on the anti-Chinese sentiment but to offer real challenges in the form of top-end devices with solid internals at affordable price points, feel industry experts.

"The current market conditions in India are fluid and open up new opportunities for smartphone original equipment manufacturers (OEMs) to focus and leverage," Prabhu Ram, Head-Industry Intelligence Group, CyberMedia Research (CMR), told IANS.

In the first quarter (January-March) this year, Samsung's shipments were driven by its upgraded A and M series (A51, A20s, A30s, and M30s).

According to Counterpoint Research, Samsung managed to hold third position in Q1 2020 due to launches across several price tiers, especially in the affordable premium segment (S10 Lite, Note 10 Lite).

The South Korean smartphone maker last week announced a Rs 4,000 price drop on its popular Galaxy Note10 Lite smartphone that will now cost Rs 37,999 (6GB variant).

Earlier this month, Samsung launched two new smartphones, Galaxy M11 and Galaxy M01, with powerful batteries under Rs 15,000 in India.

Galaxy M11 comes in two variants. The 3GB+32GB will be priced at Rs 10,999 while the higher 4GB+64GB variant will be available for Rs 12,999.

Samsung has also launched an affordable Galaxy A21s smartphone with quad-camera system and 5,000mAh battery at a starting price of Rs 16,499.

On the other hand, Apple grew a strong 78 per cent YoY driven by strong shipments of iPhone 11 and multiple discounts on platforms like Flipkart and Amazon in Q1, according to Counterpoint.

Apple has also brought its cheapest yet powerful new iPhone SE that costs Rs 38,900 (64GB) in India with a special offer from HDFC Bank. The new iPhone SE is powered by the Apple-designed A13 Bionic, the fastest chip in a smartphone and features the best single-camera system ever in an iPhone.

According to Tarun Pathak, Associate Director, Counterpoint Research, consumer sentiments are running high and a section of users will look for alternatives, benefitting global and Indian brands.

"However, we do not think non-Chinese brands will run aggressive campaigns based on the situation as it might look like being opportunistic," Pathak told media.

It may actually let brands of Chinese origin try to run aggressive campaigns on their presence and scale.

"Some of these Chinese brands have been active in scaling up local value addition, creating jobs and investing in research and development," Pathak noted.

On Saturday, market leader Xiaomi said that it is "more Indian" than any other smartphone brand.

The company's India head Manu Kumar Jain said that the company's mobile phone R&D centre and product team is in India, it employs 50,000 people in the country, the entire leadership team is Indian and that the company pays its taxes in India.

Earlier, Realme India CEO Madhav Sheth who is also very active on social media said that Realme is an Indian startup.

In his latest episode of Ask Madhav' series on YouTube, Sheth said: "I can proudly say Realme is an Indian startup, which is now a global MNC (multinational corporation)".

New Delhi, Jul 18: India's national cybersecurity agency CERT-in, has warned people of credit card skimming spreading across the world through e-commerce platforms.

Attackers are typically targeting e-commerce sites because of their wide presence, popularity and the environment LAMP (Linux, Apache, MySQL, and PHP), the Computer Emergency Response Team (CERT-In) said in a notice on Thursday.

Recently, attackers targeted sites which were hosted on Microsoft's IIS server running with the ASP.NET web application framework, it said.

Some of the sites affected by the attack were found to be running ASP.NET version 4.0.30319, which is no longer officially supported by Microsoft and may contain multiple vulnerabilities, CERT-In said.

The notice also included a list of best practices for website developers including the use of the latest version of ASP.NET web framework, IIS web server and database server.

The advisory is based on research by Malwarebytes which found that this skimming campaign likely began sometime in April this year.

Credit card skimming has become a popular activity for cybercriminals over the past few years, and the increase in online shopping during the pandemic means additional business for them, too, Malwarebytes said in a blog post, adding that attackers do not need to limit themselves to the most popular e-commerce platforms.

Researchers from global cybersecurity and anti-virus brand Kaspersky had warned in December last year that more cybercriminal groups will target online payment processing systems in 2020. 

It said that over the past couple of years, so-called JS-skimming (the method of stealing of payment card data from online stores), has gained immense popularity among attackers. 

Kaspersky researchers in their report said they are currently aware of at least 10 different actors involved in these type of attacks.

Their number will continue to grow during the next year, the report said, adding that the most dangerous attacks will be on companies that provide services such as e-commerce as-a-service, which will lead to the compromise of thousands of companies.

In the wake of the gas leak at a factory in Visakhapatnam, the National Disaster Management Authority (NDMA) has issued detailed guidelines for restarting industries after the lockdown and the precautions to be taken for the safety of the plants as well as the workers.

In a communication to all states and union territories, the NDMA said due to several weeks of lockdown and the closure of industrial units, it is possible that some of the operators might not have followed the established standard operating procedures.

As a result, some of the manufacturing facilities, pipelines, valves may have residual chemicals, which may pose risk. The same is true for the storage facilities with hazardous chemicals and flammable materials, it said.

The NDMA guidelines said while restarting a unit, the first week should be considered as the trial or test run period after ensuring all safety protocols.

Companies should not try to achieve high production targets. There should be 24-hour sanitisation of the factory premises, it said.

The factories need to maintain a sanitisation routine every two-three hours especially in the common areas that include lunch rooms and common tables which will have to be wiped clean with disinfectants after every single use, it added.

For accommodation, the NDMA said, sanitisation needs to be performed regularly to ensure worker safety and reduce the spread of contamination.

To minimise the risk, it is important that employees who work on specific equipment are sensitised and made aware of the need to identify abnormalities like strange sounds or smell, exposed wires, vibrations, leaks, smoke, abnormal wobbling, irregular grinding or other potentially hazardous signs which indicate the need for immediate maintenance or if required shutdown, it said.

At least 11 people lost their lives and about 1,000 others were exposed to a gas leak at a factory in Andhra Pradesh''s Visakhapatnam on May 7.

The incident took place after it restarted operations when the government allowed industrial activities in certain sectors following several weeks of lockdown.

The lockdown was first announced by Prime Minister Narendra Modi on March 24 for 21 days in a bid to combat the coronavirus threat. The lockdown was then extended till May 3 and again till May 17.
