Global Warming #1: Hydropower in China

Even as heat waves and forest fires rage through Europe, China’s extreme summers have their own consequences. The Yangtze river’s level is at its lowest level since 1865, says this Bloomberg article. This is a major problem for China since the river feeds “much of the country’s food and massive hydroelectric stations, including the Three Gorges Dam — the world’s biggest power plant”.

 

As the water level kept falling, electricity generation at the hydropower plants decreased. In turn, that reduction in electricity has hit everything from malls to factories.

 

Which brings me to a worrying point. Yes, we know global warming is real. Yes, we know the world needs to take more steps to switch to less polluting and alternate forms of energy. China had been increasing its share of hydro, solar and wind power contribution in that context.

 

But with successive years of droughts in different rivers hitting hydro power production, and “given that wind and solar are even less stable”, China has started increasing coal production – it’s feeling that coal is more reliable…

 

This, of course, would set off a vicious cycle. If climate change makes eco-friendly energy sources less predictable and thus less reliable, and countries start shifting back to fossil fuels, they’d be increasing the very sources that have led to global warming in the first place.

 

It’s all very well to say everyone should be willing to pay the price to create a better environment in the future, but electricity is a basic necessity of modern life that fuels economic growth and helps move people out of poverty…

Student of the Year

As a toddler, my daughter loved Alia Bhatt’s songs, esp. the ones from Student of the Year . (That movie did have many good songs and well-choreographed dances). Fast forward to present day, when she is 12 yo. She rarely watches Hindi movies now, but one of the few ones she likes of late, Raja aur Rani ki Prem Kahani has, yes, Alia Bhatt.   If I had any hopes that there was anything to be read in the name of her toddler-time favorite ( Student of the Year ), they have been dashed. Our conversations come exam time are perfectly captured by this photo and its caption: In fact, the pic below captures how she and I look at her answer sheets – me intently, she with an expression of “It’s over, so why are you even looking at it?”   Of late, we pull her leg and tell her that she isn’t showing any signs of academic prowess, she’d better find a rich guy to marry. Some time later, she showed us this meme on the Internet: “Me No Study, Me No Care Me Go Marry Millionaire If He Die

Animal Senses #7: Touch and Remote Touch

Instinctively, we think touch is based on contact. Not entirely true, explains Ed Yong in Immense World – there’s a more important aspect than contact: “These incredible feats are possible through movement. If you rest a fingertip upon a surface, you can get only a limited idea of its features. But as soon you’re allowed to move, everything changes. Hardness becomes apparent with a press. Textures resolve at a stroke.” As you run your fingers over a surface, they hit the tiny peaks and troughs and set off vibrations in the mechanoreceptors at their tips.   At the tip of its snout, the star-nosed mole has many pairs of hairless appendages. It uses them to touch things around itself. Alive or dead? Food or ignore? It does these movements at an insane speed. In the time it takes to blink our eyes, the star-nosed mole can probe, identify and swallow its food. “Light may be the fastest thing in the universe, but light sensors have their limits, and the star-nosed mole’s sense of

The Retort of the "Luxury Person"

Image
Coming up with biting and witty retorts. It’s something we dream of, but rarely manage to pull off. Worse, the more we stew over the offending remark, the more likely we are to come up with that dream retort, as Calvin ruefully points out: During our last holiday at the Taj Resort, seeing my wife carrying towels to our poolside chairs, one of the kids there mistook her for a member of the staff and asked for a towel. When my wife narrated this to us, I did not imagine that my 8 yo daughter would come up with her own retort. But a day later, my daughter recapped the incident, an incident that didn’t even involve her in the first place , and said, “You know what I’d have told that kid who asked for the towel?”. And without waiting for an answer, she told us anyway: “I don’t work here. I too am a luxury person who is living at this resort. Go get your own towel.” We were highly amused by the phrase she had coined: “luxury person”. It certainly captures the kind of holid
