For my test with DeepSeek-R1, I started by asking the ā€œdefault modelā€ a generic question: ā€œIā€™m trying to pick one growth area in my life, choose one highly effective technique and practice it every day. Can you come up with some ideas?ā€

I didnā€™t care about the answer. Just wanted to see what it came up with. It was a bland list of self-help cliches, but serviceable. Nothing special.

But there was a little button called ā€œDeep Thinkā€. This would turn out ā€œDeepseek-R1ā€ to solve reasoning problems.

@deepseek_ai

šŸ§µImage I pressed the ā€œDeep Thinkā€ button and got my second answer. But before it was a little grayed-out area where DeepSeek-R1 actually goes through its thought process. I donā€™t know the official name for this part so Iā€™m going to call it DeepSeekā€™s meta-thoughts.

ā€œOK, the user is asking for ideas to pick one growth area and a daily technique to practice. They mentioned they want something highly effective. Let me start by understanding their needs.ā€

They correctly deduce that their previous list of ten techniques was probably overwhelming. They remember in the same context window I previously asked about the DeepThink button for complex questions and hypothesized that I might want more depth.Image

šŸ‡¬šŸ‡§THE GREAT BRITISH SMR-OFFšŸ‡¬šŸ‡§

The competition to find the worldā€™s best SMR yet is ON with the Brits announcing their shortlist of 6 candidates from around the world. But more importantly, what does Angelica think about it?

Letā€™s see the contestantsšŸ§

šŸ§µ šŸ‡ŗšŸ‡øAP-300 by WestinghousešŸ‡ŗšŸ‡ø

Or should we be flying the šŸ‡ØšŸ‡¦ flag? In any case, Westinghouse is talking up the AP-300 as the AP-1000ā€™s little brother.

šŸ˜»shared supply chain, proven components
šŸ§whatā€™s making it cheaper if you use AP-1000 components in a smaller reactor? Image

CYANIDE AND LOAD-SHEDDING

If you ever get cynical or complacent about the state of the grid in your country, South Africa is a grim reminder that it can always get worse. They have 8 stages of load shedding. Stage 6 meaning 10hrs in the dark.

It wasnā€™t always like thisā€¦

šŸ§µ Once upon a time, the state-run electrical utility Eskom was held up as a paragon. As late as 2002, it won an award as the worldā€™s best power company. But the downward spiral wasnā€™t far behind.

The load-shedding begin in 2008 and continued ever since.

THE TURBINE WARS

Offshore wind is a curious business. Everywhere you look, deals are getting done, ambitious targets are getting set...and companies are losing money.

Revenues up...but so are losses. How can this be?

šŸ§µ

reuters.com/business/energā€¦ This is a 4MW onshore turbine. Turbine makers like Vestas and Siemens Gamesa gave been making it for years and now the supply chain is perfection. They've mastered everything about making these. Image

COAL IN THE AGE OF THE ENERGY TRANSITION

Thereā€™s no fuel more spurned and despised. Weā€™re trying to leave coal behind. Yet 2022 was a record year for for global consumption.

Letā€™s learn more about the fuel we love to hate, but canā€™t seem to quit.

šŸ§µ Image Coal is graded by energy content from the lustrous high-purity anthracite, through bituminous, sub-bituminous and finally lignite, the lowest grade brown coal. Any worse than that and youā€™re burning peat. Image

ā€œThe problem is everybody wants to build a Gigafactory but nobody wants to mine.ā€

Just had a verrrrrry interesting convo off the record with a banking person with a technical background in mining...

šŸ§µ The problem is banks, especially European banks, donā€™t want to take the ā€œreputational riskā€ of being involved in mining projects.

You can get ā€œgreen loansā€ for gigafactories, but not for the other side of the supply chain.

Norwegian developer Equinorā€™s 1GW floating wind farm is shelved, in part due to ā€œtechnology availability.ā€ Translation: they didnā€™t have their floating foundations figured out. This is a problem we are going to keep seeing with floating offshore wind.

šŸ§µ
equinor.com/news/20230522-ā€¦ There are hundreds of designs for floating offshore wind foundations, which is another way to say industry has yet to come to a consensus about what actually works.

Or rather, whatā€™s going to price-down enough to make their projects economically viable. Image

šŸ¤‘DECODING DEDOLLARIZATIONšŸ¤‘

In our lifetimes, the US dollar has always been the reserve currency of the world. But it seems every few years anxiety about the USD being toppled as the global denomination of choice rears its head

We are going thru one of those moments...

šŸ§µ As things stand, the Euro is the distant number 2 when it comes to the amount of business done around the world.

But most of the anxiety coalesces around the number 3 currency, despite the fact that it's even farther behind: the Chinese Renminbi.

People are asking whether the AP300 SMR by is late to the party.

TL;DR I think not. The AP1000 is obviously going places and can take the lil brother along. But letā€™s take this opportunity to do an SMR roundup.

Just my opinionsā€¦the SMR field not as thick as you thinkā€¦

šŸ§µ Image āš”ļøThe BWRX-300 by GE-Hitachiāš”ļø

The closest thing we have to a sure thing. Unexotic design. Experienced company. Great partners.

A great sign for success is the customers OPG, TVA and Synthos are pooling resources to mature the design, lessening First-of-a-kind (FOAK) risk. Image

What makes a car a product and a traditional nuclear power plant a project? If it's not made in a factory under controlled conditions, then it's not a product.

And that's a problem, argues @kirstygogan and Eric Ingersoll of @TerraPraxis.

šŸ§µ Image @TerraPraxis is a non-profit putting that principle, which a lot of us in the nuclear sphere know well, into practice. The reason? We need a LOT of nuclear if we want to reach out climate goals. Like, we need it in BULK.

The incredible ambition: 700GW a year. Image

Time to talk cross border collaboration to advance deployment! This is how we can standardize designs, share costs and create international supply chains!

#smr2023 ImageImage šŸ‡ŗšŸ‡²šŸ¤šŸ‡ØšŸ‡¦

šŸ‡ŗšŸ‡² We compared our licensing processes, evolved into collaboration between TVA, OPG on the BWRX-300.

Today Taiwan say goodbye to the 2nd reactor of the #2 Nuclear Power Plant, also known as Guosheng. The 985MW BWR from GE has served Taiwan well for 40 years. But for politics, it could have served for 40 more.

What a tragedyā€¦but also, a farce.šŸ§µ ā€œTaiwan is not lacking in electricityā€ is the eternal mantra of the government. Why, then, are manufacturers being ā€˜voluntoldā€™ to reduce production to save on power on a regular basis?

We all think of Germany as the Richie Rich of Europe, but kinda arrogant and sanctimonious. And what with that sweet European welfare state model, life must be good for the Germans right?

You have no idea how wrong, and youā€™ll never guess whyā€¦šŸ§µ Look at the mean household income. Yo. šŸ‡©šŸ‡Ŗ families are not just below šŸ‡«šŸ‡·šŸ‡§šŸ‡ŖšŸ‡¦šŸ‡¹, but even šŸ‡ŖšŸ‡ø and šŸ‡®šŸ‡¹. Whatā€™s going on?

I got to catch up with a grid expert in Taiwan to do due-diligence work today for a 1,044MW offshore wind farm project. He praised Taipower to the skies when it comes to grid connection. I was surprised because in TW weā€™re constantly gaslit from outside that Taipower sucks.šŸ§µ ā€œItā€™s an engineerā€™s dream,ā€ he said. Unlike in Australia, where the power producers, the grid companies and the retailers are all separate entities, resulting in a lot of vagueness and finger pointing, Taipower is in charge of everything when it comes to allocating grid capacity.

How Charles Munger can explain why your grid sucks. Specifically, his famous quote:

ā€œShow me the incentives and Iā€™ll show you the results.ā€œ

What do power plant owners want? They want high clearing prices. ā€œThe clearing prices get high when the grid is teetering on the edge of not being reliable, and even old and expensive plants are being run,ā€ explains @MeredithAngwin in a blistering presentation to the NH Nuclear Study Commission.

We hear it all the time: Gas can load-follow. But I think what we donā€™t hear about as much is the price of that flexibility. I asked a former plant manager of a Combine Cycle Gas Turbine (CCGT) plant about exactly happens when a CCGT plant ā€œbacks upā€ renewablesā€¦šŸ§µ First of all CCGT plants are some of the most efficient power plants in the world, with the latest technology ā€œexceeding 60% thermal efficiency.ā€ However, that performance becomes suboptimal when the plant operates at part-load to counter the intermittency of wind and solar.

Weā€™re going to see more of this: DPP legislator Chen Hsiu-pao just expressed curiosity about SMRs, asking Taiwanā€™s top nuclear regulator in a public forum what the possibilities are. Image I canā€™t believe the power of the SMR concept to get people to think again. However Iā€™ll take it. Atomic Energy Council Minister Hsieh Shou-shing replied that nuclear waste is still the most pressing problem and SMRs will still make nuclear waste.

A lot of ppl are big mad at me for being anti-EU when I am pro-EU but think the Euro was a mistake. Short version: they didn't think thru the implications of monetary union without fiscal union. Long version...I read this book. šŸ§µ Image "The Eurozone was flawed at birth," said Stiglitz. If you accept the premise that monetary policy is a useful at all, then it would stand to reason that giving up control of that tool to a foreign entity might be risky. This might not be so bad for a bunch of similar economies...

"In our excitement for Net Zero we've forgotten about security, affordability and reliability." I sat down with energy consultant @KathrynPorter26 to unpack what went wrong globally and what the UK govt should do specifically. This will be an epic šŸ§µ First of all, let me tell you, the situation here is dire for individuals and small businesses. A friend with a decent job actually told me he would take off to work from Spain for the winter to avoid the bills if it weren't for his cat.

Had an incredible convo in a Soho basement with a young man who thought we shouldn't build nuclear power plants because we should use the money to plant trees. šŸ§µ Incredibly, he used South Africa as a MODEL...they just switch off the grid at times and "people just get used to it." He also (correctly) said that any new nuclear project would not come to fruition until the 2030s.
