How to pay TNEB bill online through Paytm

You can now pay electricity bills in Tamilnadu through the Paytm and Paytm Lite apps.
How to pay through the Paytm app:
Once you open the Paytm app, click on the Electricity icon. You will be taken to a page that will have two tabs - Electricity Boards and Apartments. Click on the Electricity Boards. You will get a dropdown of all the states. Select Tamil Nadu. It will now show the electricity board's name 'Tamilnadu Electricity Board'
You will now have to key in your Consumer Number. You have to enter your Consumer Number starting with Region Code, followed by Section, Distribution and Service Number and click on Proceed. Once you do it, Paytm will fetch your details, which may take a minute or two. This will include your name, due date, bill number, bill date, bill period and the due amount.
If you have already paid, you will get a note saying the bill has been paid and that there are no dues.
You can use the 'Fast Forward' option and click on Proceed to Pay, which will immediately pay from your Paytm wallet balance. You can apply one of the listed promo codes to avail of the discounts.
If you don't select the Fast Forward option, it will take you to the Paytm login page. Once you key in the details, you will get an one-time password (OTP).
The next screen will give you options to pay from Paytm (again), debit card, credit card or net banking.
The rest of the process is the same as in other payments. You will have to key in the credit card or debit card details, or in the case of netbanking, log in to your bank account and complete the process.
As of today, there is no option to pay through the United Payments Interface (UPI)
How to pay using Apartments list:
Log in to the Paytm app. Once you click the Electricity option, click on the Apartments tab. At present, it is restricted to the 11 apartments listed. More will be added soon. You will now be asked to key in your mobile number. Paytm will now find out whether there are any dues. If there are dues, you will have to go through the previous process.

How to use your mobile as webcam or security cam

There is no need to go for an expensive CCTV set up if you want to keep a small area under surveillance, especially if you want to monitor only occasionally.
You will need a mobile with camera, a power source and enough bandwidth to stream the video.
This tutorial is for Android.
First, download the Ipwebcam app from the Google Play Store. In the menu, scroll down and click on 'Start Server' to begin streaming. Position the mobile covering the area you want to stream.

Vodafone Rs. 99 Recharge Offers Unlimited Calls to Compete with Jio, Airtel

  • The new Rs. 99 Vodafone recharge offers bundled local and STD calls
  • It has validity of 28 days
  • The recharge can be purchased via official site and app

Jio started its telecom operations with the promise of unlimited free calling for all its recharges, a boon for subscribers in smaller cities with not as much demand for data as there is for calls. It was no surprise that operators such as Airtel, Vodafone, Idea, and BSNL jumped on the Jio bandwagon with data recharges having bundled calls. Then came the turn of relatively affordable recharge packs with just voice calling to cater to this segment. Now, a new Rs. 99 Vodafone recharge pack has been launched to offer bundled calls to prepaid subscribers of the operator. It will compete with the Rs. 98 Jio recharge, which offers data as well as calling benefits.
The Rs. 99 Vodafone recharge offers bundled calls limited to 1,000 minutes a week and 250 minutes a day, a customer care agent confirmed. It is available to purchase from the official Vodafone app and website but not on third-party sites such as Paytm and MobiKwik yet. The validity of the pack is 28 days. However, there are no data and SMS benefits with the pack.
Competing with the new Vodafone recharge is the Rs. 98 Jio recharge, which offers 1GB data per day and 300 text messages, along with the unlimited voice calls. It also has validity of 28 days.
Airtel top offers bundled local and STD calls, 1GB data, and 100 SMS with its Rs. 99 pack. However, its validity is just 10 days, much less than what Vodafone and Jio are offering.

Why I work at a National Lab.

Over the years, one question that keeps popping up is why I decided to work for a National Lab, as opposed to a university or industry.  My first answer to this question, which is �because John Travolta once told me that without a job, residence or legal tender, I will be a bum� does not seem to lead to satisfaction.  So, here is the alternate answer.

When I first came to a National Lab, I really had no idea what a Lab did versus these other entities.  I had heard the origin story (the Manhattan project), seen the big, unique, expensive facilities (the synchrotron sources and the nano-centers) and knew the names of the many of the scientists in the complex as leaders in their field.  But it took a few years of being at a Lab (after I got past the �do not become a bum� phase) for me to really understand their critical role in scientific innovation.

At its core, scientific discovery has become hard.  The days of the inventor who tinkered on something in the garage and discovered the next big battery breakthrough are long gone, unless you are developing battery apps.  The �low hanging fruits� have all been picked.  The world still needs new discoveries leading to better technologies; so we have had to, and will continue to, go higher and higher up the proverbial tree.  

National Labs were/are built to satisfy this need.  In my opinion there are three aspects to a national lab, the first two being:  (i) take a bunch of smart scientists and engineers from diverse disciples who are willing to dedicate their life, working as a team, to solve a problem, and (ii) provide them with the means to build unique facilities (think big $$) and capabilities (think brains), unlike any other in the world.  Do this long enough that this combination will yield new breakthroughs, new insights, Nobel prizes, and the rest of the good stuff.  And out of this mix emerges the thought leaders who define the next phase of innovation and set the path for what will be the future. 

In the age when the great industrial research labs are all long gone, this role takes on an even greater importance.  

But there is a third aspect to a National Lab which, in my opinion, is equally important.  We are taxpayer funded and have an obligation to help the taxpayer in whatever way we can.  Which means that it is not enough to develop (i) and (ii) and then keep it behind closed doors, with an insular approach to problem solving.  Rather, our mandate is to use said facilities and capabilities to help the broader community gain further knowledge, aid in their quest to discover new things, win their Nobel prizes, and serve as a means of enabling new products that will drive the next big market. 

But there is lack of understanding among the larger science and technology community about this aspect of Labs.  This is especially true for companies.  For one, we at the Labs do not do a great job of explaining what we have and the breadth of our capabilities.  There is a translation problem between a Lab scientist explaining a new technique and a company scientist understanding how that technique can solve a battery problem. 

And then there is confusion about the ways to even work with the labs.  Companies often don�t realize that they there are well-established mechanisms to work with Labs, that protection of IP and confidentiality are built into these relationships, and that the Labs actually WANT companies to work with them. 

A decade ago, during the cleantech boom, I was able to witness this issue firsthand.  As companies started investing more into commercializing new technologies, the translation problem became an obstracle in leveraging the assets in the National Labs to effectively move forward.  Since those days, I have been passionate about finding ways to solve this problem. 

In June 14th, we are embarking on another part of the journey to solve the translation problem with, what we are calling, �Battery Industry Day at Argonne�.  On that day, we will open up the door to industry (and others) to show you what we have, both the people and the facilities, tell you a bit about what we do, hear from you on what issues you face, and introduce you to the various mechanisms we have to work with outside entities. 

We will talk about three areas where Argonne has deep expertise: high-energy batteries used in everything from cell phones to EVs, stationary storage and its integration with the grid, and batteries for our national security needs.

You can read a bit more about the day and register at this site.  Ping me with any questions.

All you need to know about batteries: in a dozen tweets.

I've been told that my blog posts are very long.  I have been known to retort that no one reads anything anymore.  After a few years of going back and forth on this I have come to the conclusion that if you can't best them, join them.  

Research (an euphemism for "made up") suggests that the human brain can't take more than 140 characters.  So here goes.  A summary of batteries in a dozen bite-sized tweets: 

Guess which battery will power most phones, EVs, and home solar in 2025?  A lithium battery. Yes. Really. Good luck new chemistries.

A battery fire is a feature�in Antarctica. For the rest, so wish we had new chemistries.  Water, where art thou? Hate flammable electrolytes.

Lead-acid (yes, that old dog), will destroy Li-ion for grid storage. Oh ya� there is that sulfation thing to solve. 

The 2017 Li-ion battery is not your grandfathers one.  It is oh, so different on the inside. Don�t judge a book by its cover.

Is there a solid-state battery in your EV future?  Not unless you are less than 50 years old (assumption: life expectancy=70). I made it.

EV battery roadmap: High voltage then silicon, then Li metal, sulfur, (oxygen?), Mg (Al?). After that? Aliens tech. Or maybe fluorine.  

Grid battery roadmap: Li-ion or lead-acid or flow or sodium or Zinc or... Who knows. Confused? So is everyone else. Except the aliens.

Hear about an amazing breakthrough in batteries? Safely ignore it. The inventors did when they violated a few laws of nature. 

All battery companies will claim to drive cost to less than $100/kWh sometime in the future. Even if they make the battery out of solid gold.  

Performance of any battery will fall (just) short of expectations irrespective of the complexity of the device it is powering.

Pull the plug. Your battery will thank you.  And don�t use the wrong rules for the wrong battery. Memory effect is so 1995.   

It takes 10 years and $250M to start a battery company. Unless you are in China. Then it takes 1 year and $50M. Gotta love incentives.
