Repost: Tackling Agrarian Crisis

Hello again friends!

Note: This is a repost of “Tackling Water Crisis” which I uploaded at 3:46 PM today (May 30), but when I changed the title of the post, the content disappeared!

I was wondering this morning… Drought has gripped most parts of India and more than 300 million people are affected. So an idea that immediately crossed my mind was the artificial showers that were successfully implemented in the UAE.

Scientists Create 52 Artificial Rain Storms in Abu Dhabi Desert

Indeed, this can be used to bring in rain when the need arises.

But when there’s the need for sunshine, we can’t merely use artificial light to substitute sunlight.

http://www.sciencealert.com/scientists-have-created-artificial-sunlight-that-s-real-enough-to-trick-your-brain

Sunlight contains valuable nutrients such as Vitamin D, Calcium, etc, which help nourish the crops to enable them grow better. In the meantime, I’ll be thinking of artificial means to transmit all nutrients that are present in natural sunlight in the absence of adequate natural sunlight.

By the way, here are a few videos of Keukenhof, the Flower Garden of Europe situated in Lisse in the Netherlands.

Beautiful, isn’t it? However, we in India are reeling under drought and can’t even get enough water for basic sanitation, forget making Keukenhofs here at the moment! Suffice to say if we manage water and sunlight properly and learn to tackle unfriendly weather conditions, we can make more Keukenhofs at home ourselves!

Back to the topic: I propose a protective housing over vast farmlands that are close to each other.

Phew! The above images alone took more than 40 minutes to draw on Microsoft Paint! Drawing them by hand is far far easier, but my laptop isn’t touchscreen, nor can I connect my scanner to my laptop at present! Against all odds!

Coming to the first image: The green fields indicate the crops being grown, say paddy, maize, wheat, etc. The blue and light blue tiles constitute the housing over which rain falls and runs down into the drain (dark blue). This is during the rainy season. However It’s a glasshouse, a strong glasshouse with small pipes over its roof to collect all the falling raindrops. I couldn’t draw it on Microsoft Paint. It will take a vast amount of time, but I personally have a clear idea as to what I intend it to be.

Coming to the second image: The cylinders (250 meters tall and 100 meters wide) below the ground collect the rainwater and direct them to the following/next cylinders through horizontal cylinders (that are 40-50 meters below the ground and 100 meters wide). I’ve drawn 2 cylinders, but instead of 2, we can use 3, 4, up to 10 cylinders depending on the number of crop fields adjacent to each other. The last cylinder passes on the water to a pressure-controlled water tank which processes and releases the water on to the nearest water body, which maybe a lake, a river, or an estuary. After all, even the great oceans depend on the rain for its water as described by Thiruvalluvar in the 2nd chapter of the Thirukkural. To put it in short words, this is a garden variety of the G-Cans flood defense system which I briefly described in one of my previous posts.

To summarize my post:

  1. Use cloud seeding to usher in artificial rains during the drought season and when farmers need water to grow their crops.
  2. Use artificial sunlight and nutrient transmission to nourish crops in the absence of adequate sunlight.
  3. Use a flood proof protective glasshouse to sustain heavy rains, floods and hurricanes, and prevent damage to crops.
  4. Return the water back to the natural water bodies to preserve nature. If need arises, use less than half of the water for personal, sanitary and other purposes, but it’s obligatory to return nature’s property back to her.

That’s it for today folks! Thank You all for your valuable time!

We Have Sizable Shale Oil Resources, Why Not Exploit Them for Certain Uses?

Hello Again Friends!

While looking at articles to pen my previous post on a drainage system to sustain floods and heavy rains, I chanced upon the fact that Chennai has a sizable amount of shale in its soil from Wikipedia. I was involved in a conversation with a friend of mine a month or two back and he revealed that the US was exploring shale oil as a substitute to crude oil. In a flash that conversation came to mind and the idea to exploit shale to produce our own substitute for crude oil hit my head.

There’s a saying in Tamil:

புதையல் மீது அமர்ந்தாலும் அடுத்தவன் எச்ச சோத்துக்கு ஆசைப்படுவது.

That is, desiring for what someone else is eating (that too directly from his plate!) while sitting above a treasure trove.

This saying stands not just for Tamils and Tamil Nadu but for Indians and India as a whole. India in my honest opinion has enough to become a superpower, nay, an empire. But this shameful behavior of Indians and Tamils as a whole has turned India into a gutter nation from where talent flees to greener pastures.

Okay, back to the topic of this post that is shale oil.

Though shale oil has a production cost higher than that of crude oil, there’s no harm in attempting to extract shale for energy as crude oil is rapidly depleting and running out at this point of time.

https://www.pwc.com/gx/en/oil-gas-energy/publications/pdfs/pwc-shale-oil.pdf

Some Wikipedia articles are available regarding Shale Oil:

https://en.wikipedia.org/wiki/Shale_oil_extraction

https://en.wikipedia.org/wiki/Shale_oil

Shale is present in plenty in Chennai’s soils. It’s a mud-stone and can be commonly found in mud.

https://upload.wikimedia.org/wikipedia/commons/c/c5/ShaleUSGOV.jpg

Above is a sample of what the mud-stone shale looks like.

http://www.claysandminerals.com/materials/shales

Typical components of oil shale gas are usually methane, hydrogen, carbon monoxide, carbon dioxide, nitrogen, and different hydrocarbons like ethylene. It may also consist of hydrogen sulfide and other impurities. (Source: Wikipedia).

Indeed, shale oil can be used to produce gasoline, diesel and jet fuels.

Here are 2 patents on Google that can give us an idea as to how we can use shale and clay:

http://www.google.com/patents/WO2014014888A1?cl=en

https://www.google.com/patents/WO2014004193A1?cl=en

Here are a few articles that highlight how to extract oil from shale.

Oil Shale Extraction Methods

Using shale and clay, I guess we can make Chennai the energy capital of Tamil Nadu. I believe every city has enough shale and clay for self-sufficiency, but since I live in Chennai, I focus on Chennai.

Thanks a lot to all my readers for your valuable time.

Drainage System Proposal to Counter Floods and Hurricanes

Welcome back friends!

It’s been raining for the past few days here in Chennai. Usually rains bring about a sensation of joy, especially in a place like Chennai where people experience its climate in terms of hot, hotter and hottest. But this was not the case during the infamous Chennai floods of November and December 2015 that left thousands of people homeless (at least temporarily) and led to upwards of millions of US dollars in terms of monetary losses to the public and possibly billions to the city and the state as a whole. More on that rather (wo)man made disaster here. So another similar rain at present (the week starting May 15-16 2016) followed by intermittent power cuts gives that eerie sensation that we’re in for another wild ride!

So I was wondering today (May 18, 2016) as to what can be done in order to save lives, businesses and properties from heavy damage in the future.

I read 2 articles on Japan’s G-Cans drainage system that has effectively mitigated the effects of heavy rainfall and tsunamis that are quite regular in that archipelago.

https://japangasm.wordpress.com/2012/01/12/the-underground-wonder-of-tokyo/

http://web-japan.org/trends/11_tech-life/tec130312.html

I thank the Japanese companies, scientists and engineers who came up with this brilliant idea and credit them completely. I take no credit for the articles or ideas above. This post is just my opinion and sharing inspired by their ingenuity and brilliance.

As I write this blog post, the rain seems to have reduced and the threat seems to be mitigated, but I keep my fingers crossed, just in case!

Look at these videos of the G-Cans flood defense system:

Here’s a UNESCO resource for different types of sewer systems (not to be confused with the drainage systems used to sustain floods and heavy rains):

http://ocw.unesco-ihe.org/pluginfile.php/440/mod_resource/content/1/Urban_Drainage_and_Sewerage/1_Introduction/Types%20of%20sewer%20systems/Type_of_sewer_systems.pdf

Unfortunately in a country like India, hardly a handful of people take initiatives to improve living conditions but bash each other over trivial issues such as:

  1. sloganeering (Bharat Mata ki Jai, but Bharat was a King, when did he become a mother? Was he a HERMAPHRODITE?)
  2. renaming roads (after Maharana Pratap, Akbar, Aurangzeb, etc.)
  3. wailing over a lost blood diamond (Kohinoor, which caused the annihilation of an entire dynasty in Iran!)
  4. Fighting over the legacy of Indian freedom fighters or distorting history to suit personal agendas and political vendettas.
  5. Picking fights with and over college students and purging universities.

… and many more. Put me in the ‘not interested’ category if you will, as this ain’t gonna help any of us when push comes to shove!

How that’s gonna help us at present or in the future is out of question. What’s standard practice in almost all countries seems futuristic or impossible in a country like India. Shame.

Okay then, it’s time to get back to the topic of this post: The Drainage System.

Here’s a proposal for Chennai city which I think needs more modification but will still be as effective.

A map of Chennai below:

https://i1.wp.com/www.mapsofindia.com/maps/tamilnadu/chennai-map.jpg

In the above map, with regard to the G-Cans flood defense system I propose underground discharge channels via the following routes:

  1. Meenambakkam Airport – Pallavaram – Chrompet -Tambaram with a pressure-controlled water tank (200 meters long and 80 meters wide) setup at Tambaram around 50 meters below ground to discharge water into 2 water bodies near Tambaram.
  2. Ekkaduthangal – Nandanam with a pressure-controlled water tank setup at Nandanam 50 meters below ground to discharge water into the Adyar River.
  3. Velachery – Periyar Nagar – Tharamani with a pressure-controlled water tank setup at Tharamani 50 meters below ground to discharge water into the Buckingham Canal.
  4. Ambattur – Ennore Port with a pressure-controlled water tank at Ennore Port 50 meters below ground to discharge water into the Ennore Creek.

This way, water can be conserved better, heavy rains/floods can be sustained and rivers can possibly be revived.

That should do for now. In the next post, I’ll address how Chennai can produce energy from within its own resources, namely Shale Oil.

Till then, it’s bye… from Iniyavel (Twitter: @Iniyavel_)!
