It's funny that when India does feats like moon landing, UPI, etc people rightly cheer it but when people ask for footpaths or cycle lanes suddenly they spew excuses like summer is too hot, we're below $4K GDP pc, etc You grow only when you break out of constraints.

The more rich people are clustered in dense areas, the better a city works for everyone including poorest residents and future migrants. The more the rich sprawl outward, the worse it gets. Height limits plus car-centric planning are among India’s most anti-poor urban policies.
Opposing taller buildings in Indian cities is a bizarre leftist position. It ends up punishing the poorest by making drainage, waste management, cables, electricity and public transit far costlier & worse, while forcing endless sprawl where cutting lakhs of trees becomes normal.

The Indian left has grasped the American left's worst Ludditism, the Indian right doesn't understand technology and hates the actual researchers, and the Indian center wouldn't know technology if it hit them in the face India desperately needs to center tech literacy in all wings

Partly explained by this:
People in Tamil Nadu act as though they’ve been living under oppression, mistreated by the DMK government, held at metaphorical gunpoint, and desperately waiting for some saviour to rescue them from imagined horror and slavery.

The West is obsessed with Chernobyl, churning out award-winning series about a 1986 disaster that killed 54 people on impact. Yet they remain silent on Bhopal 1984, where an American-owned factory leaked gas, killing 3,500 people instantly.
Raghu Rai’s portfolio of the 1984 Bhopal industrial gas disaster are among the most profound photojournalistic works of the last 50 years raghuraifoundation.org/bhopa…

A good thumb rule: any analysis/ commentary on rising temperatures in cities that attributes the cause singularly to climate change is highly likely to be wrong. Reason being the fact that built environments (concrete, asphalt and glass) absorb a lot of heat

Tamil Nadu faces one of the most crucial elections in its history. With population growth stabilising & the average age now 36 , the next 10 yrs will decide: will TN remain lower-middle-class or finally rise to upper-middle-class prosperity? Need eagle-eyed focus on economy 1/3

More proof, why indian cities need to grow vertical, design according to the wind, prioritise shade both green and gray. Stop sprawling into the forests. Metropolises like Bangalore, will probably feel less cooler in the coming decades cause it's on a sprawling spree.
IIT Bombay research shows that heatwaves over the Indo-Gangetic Plains are primarily driven by local land and atmospheric factors, rather than by hot air travelling from elsewhere. New research led by Prof. Karthikeyan Lanka, Associate Professor, Centre of Studies in Resources Engineering and the Centre for Climate Studies at IIT Bombay, shows that not all IGP heatwaves are the same, and the factors driving their origin are more local than distant. iitb.ac.in/research-highligh…

Chennai & other cities in TN will keep sleeping. An earthquake prone state is building taller. Shameful!! 😑🤷‍♂️

Chennai folks should stop opposing skyscrapers Skyscrapers are good for the same reason buses, trains or nuclear plants are good. They serve more people but need less space & resources It’s far easier to build infrastructure like metros or sewage to support vertical clusters than horizontal sprawl. Which is easier: build metro to cover 200 km² or 1000 km² ? Services like garbage collection are also easier for vertical growth than urban sprawl When a school kid distribute chocolates to classmates for birthday, which is easier: visiting each of their homes? or giving when they’re all in the classroom? Our current FSI limits are akin to banning local trains or buses. Imagine how stupid & inefficient that would be! Already TN's tax money is redistributed up north; the little that remains shouldn't be wasted on maintaining suburban sprawl
Why do Indians think skyscrapers are desirable?

Coimbatore is such a cracked city It deserves 2x the infrastructure that it currently gets, with proper footpaths, bus lanes, FSI relaxation, and metros But in India, we don't believe in investing in successes, so all we get is mediocrity. Places like Coimbatore are ignored by both Central and State govts Heck, Cbe even has more GCCs than every other tier 2 city
Something I keep coming back to: The precision machining cluster in Coimbatore exports to Tier-1 automotive suppliers in Germany. The German buyer knows Coimbatore. The Indian policy conversation doesn't.

Anti-nuclear folks opposing PFBR is very ironic, considering that: 1. Fast Breeder reactors solve problem of nuclear waste. FBRs can use up the longest lived radioactive wastes produced from regular reactors. 2. FBRs also increase the energy that you get from uranium fuel by up to 80 - 100x, so it reduces the need to mine uranium Both are major wins for the environment. So why oppose? The real reason is different from the one stated. Once you oppose a solution, the "problem" can be used to oppose nuclear in perpetuity. This is why FBRs, permanent waste storage sites, etc always get special attention from anti-nuclear activists across the world.

India's PFBR is an ENORMOUS achievement Why? Look at natural uranium: mostly U238 with less than 1% of U235. Most reactors can use only that 1% PFBR converts the U238 into Pu239, which can then be used to make energy. So, you can get up 50-100x more energy from uranium Cntd.🧵
Today is a historic day. India has entered 2nd stage of our three stage nuclear power program with the achievement of clriticality of PFBR. Congratulations to every contributor to this critical technology that makes India only the second country to operate a large fast reactor.

2/n FBRs also have another cool feature: They solve the age-old issue of nuclear waste How? Using an FBR will remove the long lived fission products that are radioactive for 10,000s of years You no longer need to build expensive facilities to store nuclear waste for centuries

3/n PFBR helps reduce mining impact Producing 80-100x more energy from given uranium means you need to mine less uranium This makes nuclear even more resource-efficient than it already is:

Romance movies involve walking through cobblestone streets with the love of your life, holding hands, and chatting over a streetside cafe. Even if you do find the love of your life, this is hard to do in Indian cities.
I think romantic movies do so well in India is because people get to live vicariously. In their own lives, they don't really get to date, fall in love, marry the person of their choice. They are deprived of such a basic human instinct.

Govt research in USSR did not have a pipeline to consumer goods US gov research in semiconductors led to a whole industry of consumer products, from calculators to personal computers As long as you have feedback loops with pvt sector, public research is essential for India
Let's look at a counterfactual. What if government spending on R&D is completely slashed? Will corporate R&D follow different and perhaps more efficient path dependencies in raising overall productivity? Soviet Union spend a lot of R&D and much of it didn't translate into productivity. Maybe there is "tech search space" in abstraction that's better perused by markets forces than public R&D?

- Electrification is good for energy security & reducing pollution - The storage, transmission costs can be reduced by adding more nuclear in the mix with renewables France shows the way. ~70% powered by nuclear, 20% thru renewables, so it's 90% clean. No need for all that gas
The core analytical error in the "primary energy fallacy" argument, that renewables plus electrification will dramatically cut total energy needs, is that it treats energy as interchangeable. A TWh of gas isn't just energy. It's dispatchable, energy-dense, and seasonally storable. A TWh of solar is none of those things without substantial infrastructure to make it so. The leap from "EV motors are more efficient than combustion engines" to "the transition is easier than you think" skips over the hardest parts of the problem. Electrification can eliminate some conversion losses while introducing new ones, like curtailment, storage round-trip losses, overbuild, and grid expansion. If we look at how much infrastructure is needed to support an electric heat pump with renewables in the dead of winter, we'll see that gas delivers far more value than a Sankey diagram shows.
