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.

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.

Giving each and every app access to personal information stored on Android smartphones such as your contacts, call history, SMS and photos may put you in trouble as bad actors can easily use these access to spy on you, send spam messages and make calls anywhere at your expense or even sign you up for a premium "service", researchers from cybersecurity firm Kaspersky have warned.

But one can restrict access to such information as Android lets you configure app permissions. 

Giving an app any of these permissions generally means that from now on it can obtain information of this type and upload it to the Cloud without asking your explicit consent for whatever it intends to do with your data.

Therefore, security researchers recommend one should think twice before granting permissions to apps, especially if they are not needed for the app to work. 

For example, most games have no need to access your contacts or camera, messengers do not really need to know your location, and some trendy filter for the camera can probably survive without your call history, Kaspersky said. 

While decision to give permission is yours, the fewer access you hand out, the more intact your data will be.

Here's what you should know to protect your data.

SMS: An app with permission to send and receive SMS, MMS, and WAP (Wireless Application Protocol) push messages, as well as view messages in the smartphone memory will be able to read all of your SMS correspondence, including messages with one-time codes for online banking and confirming transactions.

Using this permission, the app can also send spam messages in your name (and at your expense) to all your friends. Or sign you up for a premium "service." You can see and conrol which apps have these rights by going to the settings of your phone.

Calendar: With permission to view, delete, modify, and add events in the calendar, prying eyes can find out what you have done and what you are doing today and in the future. Spyware loves this permission.

Camera: Permission to access the camera is necessary for the app to take photos and record video. But apps with this permission can take a photo or record a video at any moment and without warning. Attackers armed with embarrassing images and other dirt on you can make life a misery, according to Kaspersky.

Contacts: With permission to read, change, and add contacts in your address book, and access the list of accounts registered in the smartphone, an app can send your entire address book to its server. Even legitimate services have been found to abuse this permission, never mind scammers and spammers, for whom it is a windfall.

This permission also grants access to the list of app accounts on the device, including Google, Facebook, and many other services.

Phone: Giving access to your phone means permission to view and modify call history, obtain your phone number, cellular network data, and the status of outgoing calls, add voicemail, access IP telephony services, view numbers being called with the ability to end the call or redirect it to another number and call any number.

This permission basically lets the app do anything it likes with voice communication. It can find out who you called and when or prevent you from making calls (to a particular number or in general) by constantly terminating calls. 

It can eavesdrop on your conversations or, of course, make calls anywhere at your expense, including to pay-through-the-nose numbers, Kaspersky warned.
