When You’re Right, you’re Right. Elon Musk Schools Tech Bros on Solar Power

Even fascists can be factually correct.
Main body of the tweet above:


“The sun is about 99.8% of the mass of the solar system. Jupiter’s about 0.1% and everything else is in the remaining 0.1%, and we are much less than 0.1%. So, if you burnt all of the mass of the solar system, then the total energy produced by the sun would still round up to 100%. If you just burnt Earth, the whole planet, and burnt Jupiter, which is very big and quite challenging to burn, turn Jupiter into a thermonuclear reactor, the sun is 99.8% of the mass of the solar system and everything else is in the miscellaneous category.

Basically, no matter what you do, total energy produced in our solar system rounds up to 100% from the sun. You could even throw another Jupiter in, so we’re going to snag a Jupiter from somewhere else, you could teleport two more Jupiters into our solar system, burn them, and the sun would still round up to 100%. As long as you’re at 99.6%, you’re still rounding up to 100%. Maybe that gives some perspective of why solar is really the thing that matters. And, as soon as you start thinking about things at a grander scale, like Kardashev Scale 2 civilizations, it becomes very, very obvious.

I’m not saying anything that’s new, by the way. Anyone who studies physics has known this for a very long time. In fact, Kardashev, a Russian physicist who came up with this idea, I think, in the 1960s, just as a way to classify civilizations, where Kardashev Scale 1 would be, you’ve harnessed most of the energy of the planet, Kardashev Scale 2, you’ve harnessed most of the energy of your sun, Kardashev 3, you’ve harnessed most of the energy of a galaxy.

Now we’re only about 1% or a few percent of Kardashev Scale 1 right now, optimistically. But as soon as you go to Kardashev Scale 2, where you’re talking about the power of the sun, then you’re really just saying everything is solar power and the rest is in the noise. Like, the sun produces about a billion times, or call it well over a billion times more energy than everything on Earth combined.” All-In Podcast, October 31, 2025

  1. Or you could say that the sun, and the whole local group, are just fragments of the supernovae/neutron star collisions that each put out more energy in seconds than the sun will in ten billion years, and that produced all the elements heavier than iron. One of those, uranium, is about a thousand times more common in the earth’s crust than it is in meteorites or stars – uranium would much rather mix with crustal type rocks than with the iron of the core. Once life got around to producing free oxygen in the atmosphere, uranium became water soluble as well, so now we find deposits that are thousands of times more concentrated still. Half of the immense energy that was crammed into those primordial nuclei is still around, four billion years later, and for thorium, most of it is. In contrast, the average energy production of the sun is about the same, per unit volume, as a good compost heap. Sheer size brings that up to an impressive figure, and if you’ve got enough area, you can collect some of that energy. That doesn’t mean it’s the only, or the best, source. Humanity developed further in the last 200 years, with concentrated carbon power, than in the previous 200 thousand, with solar. Uranium and thorium are a million times more energy dense than carbon.


    1. And nook boosters are a million times more dense than normal people. They’re unable to get past their addiction to destruction or the psychological symbol of domination that smashing atoms in centralized facilities that allow them—well, others—to continue to monopolize and dominate energy for all humans.

      Who cares what the concentration of the sun is? To talk about it as if it matters is manipulative. We get 10,000 times more energy than we use, delivered daily, for free, from that pathetic and sad energy source, the sun. Not counting the wind it drives. Comparing primitive use of solar to PV, CSP, solar smelting at more than 6000F, with meaningless statistic outs, is also manipulative.

      Solar is better because it’s cheaper, faster, safer, healthier, reliabler, resilienter, democraticaler, ecologicaler, water-wiserer… because it’s better in every way. And it’s only part of the renewable energy system that works together to be even better than any of the parts in every one of those ways. PV, CSP, clothesline paradox energy, onshore wind, offshore wind, hydro, micro-hydro, run-of-river hydro, geothermal, tidal, bioenergy, (wave, OTEC, current, ocean salinity gradient energy…)


  2. ‘The LNT model is supported by decades of peer-reviewed research’. LNT came in in the early 50s, before the discovery of DNA, let alone of the repair systems that continually monitor its strands. It assumes radiation damage is cumulative; total exposure, not exposure rate, matters. It’s disproved daily, and runs counter to common sense. Hitting your toe with a 5 gram pencil won’t cause 1% as much damage as using a 500 gram hammer. The NRC limits max exposure to the public to about 10% of US average background radiation, but Colorado gets about double that, and residents of places like Ramsar, Iran, or Kerala, India, up to 40x as much, without any discernible health effects. Yet the NRC fined Exelon a million dollars for a tritium leak under a reactor that never reached outside the plant, and wouldn’t have harmed anyone if it had. As the NRC itself said, the damage would have been to the public’s peace of mind, not their health. Way to go to alleviate those worries, guys! Outside the nuclear industry, medicine pays no heed to LNT; tumours are repeatedly blasted with lethal levels of radiation, with the nearby tissue, getting half that dose, given enough time in between to recover. Anti-science, anti-nuclear halfwits like RFK Jr, not content with closing low carbon power sources, also help dissuade people from getting scans and treatments that can save their lives.
