15% more thrust at liftoff, 25% more in the 2nd stage and reusable fairings (should get payload to the ~45t LEO) and the announcement of a larger 9-engine variant (pictured) with 70t capacity to LEO. Basically the rocket that SpaceX should have build, but probably won't, out of spite and hurt pride.

Those are pretty astonishing numbers. Having airplane condensation trails above you at night is like having 8 times (eight times!) as much CO2 in the atmosphere (at night). The cooling effect during the day is like having 3 times less.

SHOCK: man who invented concept of "ultra processed food" – which includes such terrible nasties such as 'bread' and 'pasta' – writes review of his own working finding that he is right
Ultra-processed food is global health threat, experts warn
It is increasing our risk of a range of chronic diseases, including obesity and depression, a major review says.

Why would global warming only have major warming consequences near industrial counties?
Ask yourself: Is that what global warming, caused by a gas that is evenly distributed across the globe, would look like? Is CO2 the simplest, but still sufficient, explanation for most of this observed trend?

They made it look as easy (and as hard!) as it really is to land a rocket that was actually designed for this purpose from the beginning.
It took too long, the rocket is probably going to be too expensive and possibly too big for much of the market, but they sure proved the point.

As I said a little while ago. The future of actually useful AI won't be huge LLMs or AGI. It will be small insect-brain-sized neural nets doing just one thing, but doing it really well. Maybe we can get some actual AI for computer games too (and give those NPUs something to do as well).
Hugging Face co-founder and CEO Clem Delangue says all the attention is on LLMs, but smaller, specialized models will make sense in many use cases going forward.

Seriously, what a stupid thing to do. To make a rough assumption about what physics to apply that would have been really hard to calculate 100 years ago or 50 years ago ... thinking the world is danger and never check if this assumption actually true.
But group thinking is a powerful thing.

So, after a lot of digging, there is one that uses stimulated emission, but only for simulation of the mesosphere and thermosphere.
The reason, it's getting clear now, is the assumption of local thermodynamic equilibrium in the troposphere. Which isn't the case for photons in strong absorption lines

Going through all radiative transfer models to find hints of stimulated emission. This is probably the most blatant so far. It's using data for molecules in their electronic ground state - when they can absorb photons. But obviously don't handle excited molecules needed for stimulated emission.

Climate scientists ignoring the opposite of the infrared absorption that causes the greenhouse effect in their models sounds like a conspiracy theory.
*This is real*
The effect of stimulated emission was discovered over 100 years ago. It leads to lower greenhouse effect and it's not in the models.

Realizing that the greenhouse effect is calculated without any of the 20th century quantum physics that was invented *because* the energy transfer of light (including infrared!) was contradictory and made no sense without it, must have driven lots of scientists away from climate science.

$540 billion could pay (roughly) for 5.4 TW of PV panels. That's enough to equal all electricity consumption of the world within 6 years and keep doing that for another 20-30 years, even with conservative assumptions for kWh per kW per year.
According to a new report from the International Energy Agency, the world will spend $580 billion on data centers this year — $40 billion more than will be spent finding new oil supplies.

Btw. the guy holding the talk here is Lawrence Krauss and, as we now know, he's in the Epstein Files.
Once you understand that the theory of the emission of the upper atmosphere in regards to climate change doesn't take account of quantum effects that were discovered in 1905 and 1916, you can't unsee it.
After this slide he says "lets go from theory to data" ....

Solar is at most 25% efficient today. Wind can't be more than 59% efficient and even that is a theoretical measure.
Efficiency is a poor basis for criticism, unless you want to explain why primary energy is inappropriate. In all other cases, you (deservedly) risk getting laughed out of the room.

I don't think Fossil thermal + CCS and Nuclear power should be called "cleantech" if they're about as poorly efficient as fossil thermal.

I have to say that watching the climate guys and the fossil fuel guys completely losing their minds as they lose their influence as renewables are getting to be the cheapest energy source is both entertaining and scary. To me personally it's mostly due to the cultural influence of the former though.
