China is carrying out the solar revolution at scale. Here panels float on a reservoir in northwest China. This is just one of many massive solar power plants. The photos look like something out of science fiction:

Meanwhile Trump is fighting solar and pushing coal. The Chinese call him 建国同志, "Comrade Jianguo". Literally this means "Comrade Building the Nation". It's a joke about "Make America Great Again". It hints that Trump is actually helping China.

TIL about the super cool phenomenon of supercooled freeze pop popsicles when my son took one out of the freezer in a still liquid form and we watched it crystalize after he squeezed it. Physics is amazing!

@johncarlosbaez A reminder that China is doing nothing special, it's the society wide science denial here that's puzzling.
@snarkweek - The US is indeed puzzling and depressing. But we have to admit that China is better organized than other countries when it comes to solar. They account for over 80% of global solar panel manufacturing capacity, and they have installed more solar capacity than the rest of the world combined in recent years.
@johncarlosbaez Only because we keep sabotaging our own renewable industry.

@snarkweek - It's interesting to see how the Chinese proceed:

Ezra Klein: You had just come from China, and I had just come back from a book tour. And we were talking about something else, but then I asked you how your China trip was, and what you said to me was: Ezra, you have no idea how screwed we are.

Thomas Friedman: Yes, because what you see when you’re there is the product of 30 years of being in the fitness gym. It works like this: A new industry comes along. Let’s call it solar panels. Every major city in China decides they need a solar panel factory. The local government subsidizes it — maybe domestically born, maybe in partnership with a foreign one.

And you end up, in a very short period of time with — I’m making the number up, but 75 solar panel companies. They then compete like crazy against each other in the fitness gym, and five of them survive. Those five are so fit that they can then go global at a price and level of innovation that is very hard for a foreign competitor to deal with — which is why China today basically controls the global solar panel market.

But what you also don’t see is that process of winnowing down from a hundred of those solar panel companies to the five produced a massive explosion of supply chains domestically to feed that industry.

The same thing went on with cars. The same thing goes on with robots. So where you end up five years later is with an interlocking set of supply chains that now, if you’re a young Chinese and say: I just got this idea. I want to produce a shirt that has a pink polka dot button that can sing the Chinese national anthem backward — someone will have it for you tomorrow.

Opinion | Why Trump Could Lose His Trade War With China

The Times Opinion columnist discusses what he thinks Trump — and American policymakers — misunderstand about China in the escalating trade war.

The New York Times
@johncarlosbaez So the state is helping the industry. Same thing in the USA and EU though, where the state is doing exactly these things, except only for the fossil empire. The subsidies our societies carry for fossil are larger than the much debated 5% NATO contributions. The power structures here, the old boys networks and other furniture of our societies, they're stuck in a deadly rut so reflexively starting trade and proxy wars is not going to help them this time.
@snarkweek - I agree with you COMPLETELY about how dumb the US and (to a lesser extent) the EU is being when it comes to solar industrial policy, but you may be underestimating how smart China is being. I changed my quote to one a bit more illuminating.

@johncarlosbaez @snarkweek I’d suggest that Friedman is not seeing the whole picture. In a nutshell, building up the companies is competitive in depth, but not destructive, and the competitive focus is actual research and engineering, not marketing and financial hot air.

Chinese industry is coming out of Xi’s Gym actually fitter and faster, not just waving some team strips and branded fitness drinks shouting ‘Go Team’

@BashStKid wrote: "Chinese industry is coming out of Xi’s Gym actually fitter and faster".

That's exactly what Thomas Friedman is saying.

@BashStKid @johncarlosbaez @snarkweek

Were you on Twatter, I seem to remember following you there.

@johncarlosbaez @snarkweek

I would argue that the US under Trumpism is following the Chinese path. Currently, the US is entering Maoism and Cultural Revolution (1966 – 1976) phase. 🙃

@snarkweek @johncarlosbaez

Maybe if the USA had not voted Trump?

@lyndamerry484 @johncarlosbaez

If they had not voted in Trump, they would have had Harris. Harris would have extended Biden's policies, so virtue signaling with a tiny 0.4 tn renewables package while you refuse to transition because your fossil industry is making record profits. It's a golden cage, but a real mistake that stems ultimately from a refusal to understand how physics affect the economy.

@johncarlosbaez @snarkweek

(sometimes we forget that old puzzles have been solved)

Climate Science denial is a very Anglo-Saxon phenomenon[1]. It has has known explanations that connect it to other denials and science denial in general [2][3]. There was a network of individuals and organizations behind it.

In short:

It started in the 1950s. Anti-communism and associating government regulation with communism led to network of well funded denial. Denial of tobacco smoking causing cancer, acid rain, DDT, the hole in the ozone layer, climate change. Same organizations, lobby groups, and scientists.

It took long time to take a hold. Environmentalism remained bipartisan for a long time, Richard Nixon created the Environmental Protection Agency, signed Clean Air Act extension, Clean Water Act, the Endangered Species Act, and the National Environmental Policy Act.

They triumphed under Ronald Reagan.

@maxpool - America has become a sceptic tank. I predict that the next trend, now that weather disasters are rising unmistably, will be for climate change deniers to blame them on evil conspirators - Democrats, of course.

@maxpool - Now the climate change deniers have latched onto the fact that a company called Rainmaker was doing cloud seeding in Pleasanton, Texas on July 2nd, about 150 miles southeast of the floods in Kerr County two days later.

In the aftermath of the Texas Hill Country flooding, as well as floods in New Mexico and North Carolina, misinformation about cloud speeding is surging.

@johncarlosbaez @maxpool
Someone actually attacked a weather radar tower in Oklahoma because of this. 🤦🏻‍♀️

@johncarlosbaez @snarkweek China sees opportunities in many directions. China has a huge air pollution problem and a rising middle class that's unhappy about it. Worldwide deployment of renewables lets them address the internal pollution problem and profit by selling to the rest of the world. Trump's stupidity adds on the opportunity to take a more central role in the world politics.

This was going to be China's century regardless, but Trump is making it a lot worse for the US.

@johncarlosbaez For people wondering, building solar on water helps with both reducing evaporation and it cools the panels making them significantly more efficient.

(also some evidence of benefits wrt algae formation)

@snarkweek @johncarlosbaez this was exactly my question when I saw this. Do you happen to have the research that shows the effect? I'm curious how big the effect is.

@johncarlosbaez You know those big, dumb ass buildings y'all enjoy making so many of? Why not put them there? Stop littering.

Temporary fix.

@johncarlosbaez
In which China finally weans itself off Australian coal, only to find that Australia has the world's largest reservoirs of lithium.

@Rowena - while China produces most of the rare earths.

Maybe cooperate? Yes, I'm being naively optimistic.

@johncarlosbaez Oh, China is buying rare earths from Australian mines too. And anything else that can be dug up in fact. Only the other day I drove past a mine in remote NW Qld, out of which a contiguous stream of 4-skip road trains thundered towards the port at Bowen 500 km away. What is being mined there? Bentonite. An absorbent mineral used in kitty litter. The mine is doing a roaring trade with China. As millions of Chinese people enter the middle classes they all want to keep a pampered puss-cat in their city apartments.
@Rowena @johncarlosbaez Bentonite is used a lot in construction (drilling) and industrial applications. I bet it's those that are driving demand and not so much kitty litter.
@johncarlosbaez @Rowena Battery tech may not rely on either before long, hopefully, because that would reduce harmful mining by both nations. We already have a lot of lithium in circulation that would continue to serve for high energy density applications like the devices we’re tapping on, but SO MUCH of industrial and household storage could be done with sodium, at drastically reduced fire risk.
@cwicseolfor @johncarlosbaez @Rowena
Our house is old enough to have a coal room. Of course the coal shute has been filled in and I use the space to store stuff. I don't need the energy density of battery technology best reserved for portable objects and vehicles when the old coal room could be battery storage.
@johncarlosbaez this is so on point! Wake up US!

@johncarlosbaez

Makes sense. The chinese government loves that the world is toppling into fascism it's what has enabled them to double their coal production since 2007 and export much of it. As always, they look to save face while being a significant participant in the problems we all face.

The campaign they've undertaken to normalize global fascism alongside Russia is finally paying off for them.

@johncarlosbaez Quick aside, the characters you copied are just the transliteration of his surname (Telangpu) by which he’s most neutrally referenced, not the epithet you reference in your toot.
@cwicseolfor - I think I've got it right now. I don't know Chinese but Google Translate says it's right.
@johncarlosbaez This will be the Chinese century, perhaps because of Trump is completely gambling on US futures, sheer ego instead of sound policy. Will threats make it or break it? Because if US loses the dollar as world reserve currency, they’re going to go bankcrupt. Not chance in hell they’ll survive.

@gimulnautti @johncarlosbaez I hear European nations are pulling their gold out of the US as we speak, I mean would you have your gold kept with a madman who's mind is unravelling and is destroying the nation bit by bit?

@johncarlosbaez Floating solar cell also decreases water loss from evaporation.
@johncarlosbaez Donald destroyed America but the motivation he provided to other countries will help Earth in the long term. It's not the deal I would have chosen but there is an upside.

Thanks for the correction of the name.
建国同志 as nickname for Trump makes more sense.

@johncarlosbaez

@johncarlosbaez
The picture is phenomenal and the scale is unparalleled. Thanks for sharing!
@johncarlosbaez so... they are not putting them on top of roads? No solar roadways? But but but but- *explodes in 65535 pieces of garbage tech startup*
