In this study, they starved fat people down by 10kg over 6 months. As expected, the pure CICO group's metabolisms reduced by an average of ~250kcal/day from the carolic restriction. Fascinating: the group that did the same + wore a weighted vest for the 6 months saw almost no reduction in (resting) metabolic rate! They also maintained more of the fat loss 18 months after stopping the caloric restriction, which makes sense if you know their metabolism didn't down-regulate. Btw, 250kcal for 10kg lost is ... very bad? By this metric, my metabolism would've down-regulated by 850kcal/day. Instead, having done it without restricting calories, my metabolism is exactly where it should be. No weighted vest, either.

While I'm excited to see data center developers plan to build new clean electricity (👏), it always surprises me to hear people talk about using new nuclear SMRs for this purpose, when there are no commercially available SMRs that could bring a GW+ online before 2030 at this point. Are these data centers going to be built in 5+ years? If so, go nuclear. If not, let's be clear about what options are available.

Rod Adams@Atomicrod·
Oracle CEO (Larry Ellison) made an announcement on Monday's earnings call that he described as "bizarre." He told the audience that Oracle was going to build a data center that required 1 GW of electricity. Then he told them that the power would be supplied by three SMRs to be built on a site where there are already "building permits for three nuclear reactors". The location was not disclosed. Neither was the reactor design. Outsiders might confuse an NRC-issued early site permit (ESP) with a "building permit." If that is the case, there are 5 possible locations. (The NRC has issued 6 early site permits, but one of them was used for the Vogtle expansion project.) There are a few 300 MWe SMR designs. (Three units would be close to 1 GW) None of them has a design certification – yet. Note: I think Larry's choice of "bizarre" was a little outdated. These days, almost everyone is talking about using SMRs to power data centers.

@AaronHinman4 @AukeHoekstra Not to mention that El Hierro has been failing at phase 2 for a decade. Somehow it’s never gotten out of failure mode despite being a small and very manageable grid. Funny, ain’t it?

California is entering phase 2 of something we will see worldwide: Phase 1) Solar+wind replace up to ~70% of fossil electricity Phase 2) Solar+wind+batteries replace up to ~90% of fossil electricity Phase 3) Solar+wind+batteries+eFuels replace 100% of fossil electricity 🧵

There's definitely an issue w/ swamping like that. I think Peat is right in that SFA+carbs is the highest metabolic rocket fuel. But at the same time, most people who are metabolically unwell do not seem able to lose weight like that, or even gain weight. I know of lean people swamping like heck and being fine or even losing, and burning insane amounts of energy. But I don't know of anyone losing serious weight like that. I think @greg_barton lost some weight for a bit doing it but he was also doing near-zero protein and taking SEA and other supplements IIRC.

Peaters like to accuse ketards that we're wrecking our thyroid. Yet all the markers they can come up with, I'm totally fine. TSH: Crazy low (0.19, 0.3..) T3/4: Normal. T: Mostly >1,000 Free T: Normal. RMR by CO2 calorimetry: Normal. Don't starve yourself. Then keto's fine.

Thyroid and Low-Carb: What Do Thyroid Hormones Do? There's much too-ing and fro-ing over thyroid hormones and low-carb diets on the interwebs, in the paleo and now endurance communities, as low-carb or ketogenic diets have become popular. open.substack.com/pub/tuckergood…

@exfatloss @VERYCOOLLUKEY @greg_barton mashed Potatoes + butter is not making me leaner after 15 days, will do the month anyway, I am not gaining a gram outside of 0.5% weight variation daily from inflamation / sodium / hydration.

Germany vs France: 2023 Year in Electricity Germany burned less coal than any time in 60 years, as renewables soared, energy demand plunged, and the economy shrank. France slowly started its nuclear recovery after a precarious winter. RESULT: Germany 12x dirtier than France

@skdh Fukushima is downplayed in your video. Wind-direction was very favorably, had it blow inland the cost, would be even higher. Estimates including indirect cost are now up to 1000 billion dollars in some estimates. Have you forgotten your objective scientist background?

Out of the many bad arguments against nuclear power, there are two good arguments: It's too expensive and the power plants take too long to build. But are they true? And if so, why is it that nuclear power is so slow and so costly? youtube.com/watch?v=5EsBiC…

France seems an interesting anomaly. What’s different there compared to, say, Finland that has similar excellent provisions?

@BenBikmanPhD @SBakerMD Lost both muscle and fat, but about 2x more fat than muscle. I’m fine with that. I’ll build the muscle back.

@BenBikmanPhD @SBakerMD I did low/zero carb for about a decade. Worked great but over time my weight just crept up. Four years ago I started eliminating PUFA but that only helped slow the upcreep. In the last few months I tried protein restriction and my weight has gone down.

GROUNDBREAKING RESEARCH REVEALS MORE AUSTRALIANS 🇦🇺 SUPPORT NUCLEAR POWER THAN DON’T. Additionally, when asked if Australia was to focus on one energy source which one it should focus on, solar was first followed by nuclear at 23% beating onshore wind at 15%. The survey highlights a growing gap between support for nuclear from the public and government particularly in countries like Australia. The research was conducted by @RadiantEnergyG with 20,122 people surveyed over 55 questions. You can read the report on their website. @energybants

@AngelicaOung @EmilyZFeng @NPR @NPR is fairly anti-nuke. They’ve probably gotten the message that the anti-nuke line isn’t favored by the current US administration but that means they’ll just try projecting it elsewhere. That also shouldn’t be tolerated.

I’m super disappointed by @EmilyZFeng’s report on nuclear in Taiwan for @NPR, which totally bought into the anti-nuclear view that the Lungmen nuclear power plant is somehow a danger to Taiwan. No. It is a huge potential source of clean power! This is not about energy security vs. “environmental safety.” It’s about clean, reliable nuclear power vs. outmoded and unscientific attitudes and misplaced historical resentments. Yes, Taiwan’s nuclear power plants were constructed in the authoritarian era. So far! Build more and they won’t be! The technology itself should absolutely NOT be tainted by association! Listening to the report you’d think the KMT invented nuclear energy and have a monopoly on building it! npr.org/2023/12/16/121…

Angelica crashes a “normal” COP28 event hosted by Bloomberg. We went around the party asking people what they thought of about nuclear energy and not a single one was hard anti! Most were in the “it won’t work I’m afraid because xyz” camp and the one person enthusiastically for was like “don’t put me on the record!”

Interesting article about the prospects for SMR/advanced reactors after the NuScale "fiasco". It focuses on the Bill Gates backed Natrium reactor and the Xe-100 HTGR being pursued by Dow, b/c those are the only other reactors that have significant backing. (Article link in reply.) The article argues that those two reactors are actually in better position than NuScale was, because they get a 50/50 government cost share under the ARDP program. X-energy says that the NuScale cancellation is not affecting their plans, and that the recent layoffs and their remaining private will have no effect on their development process. Terrapower (Natrium) is entirely privately owned, and is actually going to offer the utility customer a fixed price, which is determined before construction begins! It's unclear how X-energy and Dow will split the developing and licensing costs, which are a significant up front burden for private companies to bear. According to the article, both Dow/X-energy and Terrapower will have to agree (w/ their customers) on a price before construction. All told, the commercial terms/hurdles for all these SMR venders (including NuScale) are more challenging that those the Vogtle project faced. Instead of having to offer a competitive price to utilities that will walk away if its too high, Voglte had regulated market utilities that could pass all costs to captive ratepayers (under the cost plus fixed profit margin model), and thus didn't mind cost too much. IMO, that's the main reason why the NuScale project died, while the Vogtle project moved forward. If NuScale had similar terms (i.e., was being built down in Georgia for the same utilities), would it have been built? I can't think of a reason why not. The ($89) pre-construction price that the NuScale utilities walked away from was actually similar to or lower than Vogtle's *pre-construction* cost estimate! Vogtle's final cost was ~$180. So, the per MW-hr price projections were not higher, and due to NuScale's smaller size, it would have posed a lower financial risk. As a result of Vogtle, US utilities are even more reluctant to build large LWRs than they are to build SMRs, even with the NuScale project cancellation. This isn't a SMR problem. It's a problem for US nuclear overall. We need to find ways to get the industry past the FOAK phase. New forms of policy support are apparently necessary. Fundmental regulatory / QA standard reform will probably also be necessary, IMO, if we want to build nuclear at large scale.

@EnergyJvd Time to face facts. Happy people are more active, and produce more CO2 emissions, waste, and resource use. We must ban happiness.
