Very sad to hear that Margaret Hamilton has passed away. Here's a short thread about her role in the Apollo mission, and her lesser-known work on the simulations that led to the discovery of Chaos Theory. 🧪 👩‍🔬 ⚛️

It’s certainly been interesting to compare anxious reporting that doesn’t like the precedent of the event to the scathing reviews of a lacklustre event with bad speakers from more right wing press. Hard to see this version making it.

I have absolutely no beef with taking on arguments and showing these people up! Agree with the general proposition. Was interested in your take on this specific (very US) style event and assessing whether it had potential to metastasise vs fizzle out.

Paz-Soldan argues that the scientific fundamentals of fusion have largely been solved, but the remaining hurdles are engineering challenges that require sustained, coordinated federal investment. A new kind of Manhattan Project is needed, he says. Read the fulll opinion: bit.ly/4fylWyb

Posted on LinkedIn by @globalecoguy.bsky.social: Actual versus projected buildout for solar power vs. carbon capture
Two-panel chart comparing actual performance versus modeled projections for two climate technologies, spanning 2010–2040.

Panel 1 — Carbon Capture Capacity (megatons)
Line chart. Y-axis: 0 to 4,000+ megatons. A single dark red line (actual carbon storage) runs nearly flat from 2010 to approximately 2025, remaining well below 500 megatons. Beginning around 2023–2025, a fan of teal/blue projection lines diverges sharply upward, with the highest trajectories reaching approximately 4,000–5,000 megatons by 2040 and the lowest remaining near 500 megatons. Actual performance is far below all but the most conservative projections.

Panel 2 — Solar Power (terawatt-hours)
Line chart. Y-axis: 0 to 2,000+ terawatt-hours. A single dark red line (actual solar electricity production) shows exponential growth from near zero in 2010, rising steeply to approximately 2,000 TWh by 2023–2024. A dense fan of teal/blue projection lines originates around 2023–2025 and extends to 2040, spanning a wide range from approximately 200 to 2,000 TWh. Actual solar production meets or exceeds the upper range of nearly all projections.

Implied contrast: Carbon capture has drastically underperformed projections. Solar power has dramatically outperformed them

But providers already had the prerogative to choose per the EA I thought. So we’re fine. That they overwhelmingly did not feel or ask for any need to exercise that option also seems pertinent but someone else can stand that up in the stats.

This might be one of the funniest chart about energy scenarios I’ve seen. You can hardly see “actual” for gas
Winners and Losers
The IEA overestimated gas growth in Asia and underestimated solar

Gas
• Forecast 547 TWh
• Actual 17 TWh

Solar
• Forecast 465 TWh
• Actual 1,333 TWh

Note: Shows expected growth in Asian power generation between 2018 and 2025, based on actual 2018 generation, actual 2025 generation, and the 2018 World Energy Outlook's Current Policies Scenario estimates for 2025. Actual 2025 generation figures are from Ember.

Keystone of the progress to peace there was minimising that distinction. Emphasising it over local community probably unhelpful at the best of times let alone this tense moment! I imagine the crowd is full of people from the city fed up with sectarian politics.

This is apples and oranges. Once they worked, they worked better and better. It took a long time to make them work / useful. You think fusion energy should be like a prototype solar panel from day dot. Im saying fusion is only now reaching its prototype readiness stage of your deployment model.
Plot of pace of deployment of various energy sources, starting from the day they reach 100 Terawatt-hours per year capability. Hydro and fossil fuels take 40 years to reach 1000 TWHr per year. Nuclear and renewables took 10 years.

I find it curious to characterise research investment as a deliberate deception. Especially when we know that if you want to expedite development it takes additional resource (especially financial.) Fusion is famously starved of cash relative to other energy. Gas/coal get those billions annually!

Andrew @itinerantscot.bsky.social · 05/02/2025
Well windmills took centuries to become what they are now. Semiconductors took decades to develop for solar. Fire and burning fuel took a long time to develop to fossil fuel heat exchange. Once there's a prototype things can iterate fast but research stage takes a long time.

Andrew @itinerantscot.bsky.social · 02/02/2025
So this is interesting. Because I dont think anyone ever claimed net gain. And research always takes time and improvement, in all tech. e.g. Solar used to cost 00s now costs 0. UKRI shouldnt fund scientific research we should just do insulation? (Assuming they're were the same pot of cash.)

Andrew @itinerantscot.bsky.social · 22/01/2025
Scammers claiming net energy on the grid? We very explicitly separate physics and engineering net gain in reported results. 'Power station' experiments cost more than pencils, less than oil production. I dont think the fusion share has been an outrageous amount of UKRI funds. Research takes time.

Most recent results not included. Logarithmic scientific progress on a difficult question over time included.
Two plots of fusion progress measured against time from around 1980 to 2000. Latest results not shown. One shows progress against the triple product figure of merit for fusion performance, the other shows power output in Watts. Both show clearly positive logarithmic progress.

This is the basic problem of all fusion science
Excerpt from a short story: "“It’s got a fusion engine!” Brady exclaimed. The basic concept of a fusion engine was pretty far beyond modern human understanding – but Brady knew how it would work. Step one: you have a fusion reactor that used some method to compress a fusionable material (usually an isotope of hydrogen) so that it underwent the same process that made the sun burn for billions of years. The energy released was then harnessed to, effectively, boil water and shoot it out the back of your spaceship to make it go. The difficulty was A) Step One and B) all the other parts. "
