Given how we’ve polluted and harmed the enviornment; how we’ve heavily corrupted our spiritual, social, sexual, cognitive, and mental health; how we have historically used our power for mass killing, especially in the most self-conciously scientific age; how, for the first time in human history, we’ve created a way to utterly destroy civilization and potentially the species (i.e. nuclear weapons) and have barely avoided accidentally unleashing our arsenals, what could possess us to think that we at all have the moral maturity and wisdom to rightly use the power of a sun??
There is no more god-like pretensions on our part than the attempt to build an “artificial sun.” I mean that literally. For most of human history, stars were in some way, shape, or form equated or associated with gods. For much of human history, we have operated on the principle of idolatry: we construct a thing and then look to that thing for our sustenance, security, victory in war, and fertility. Ancient humans would use rituals to trap a spirit in the idol they constructed and seek to coerce that spirit into using its power to give them such things. Additionally, especially in the ancient near east, hills and mountains were understood to be where earth and heaven met, so that is where humans would go to interact directly with the divine. This is why those civilizations built ziggurats. They were artificial mountains with an altar and idols at the top. That was how we humans tried to ascend to the divine under our own power and artifice: we would build the mountain, drag the god down, trap it in an idol, and took a very transactional approach to it to get what we wanted. This was taken to such extremes that ritual cannibalism in human sacrifices became the norm for much of humanity for a very long time.
What we do with and how we understand our science and technology follows the same pattern; we just eliminated the explicit rituals and don’t understand it as manipulating spirits. The early fathers of modern science were well aware of this and were open and honest about it. Francis Bacon explicitly understood his enterprise as a “natural magick.” We construct these things using our increasingly esoteric knowledge of the material world and constantly pin all our hopes for a better world on them, often veering into utopian language. Fusion power is always described as “clean, limitless energy.” Limitlessness does not exist in the world in which we are currently living. Limits will assert themselves, and we won’t respect them. We’ll constantly be looking to circumvent them, to our ultimate detriment.
These are our idols, and not despite but precisely because of our belief in progress, we have become enslaved to the same the spirits as were the ancients. The pattern is the same as the one followed by ancient peoples, and we are already willing to sacrifice other humans for this vaunted progress through economic and literal warfare, through industrial “sacrifice zones”, and many other crimes. Even the mere attempt to pull this off is the height of hubris, folly, and wickedness.
Enjoy your sun, but don’t fly too close.

Good news, there’s also development and early commercial applications of supercritical CO2 turbines which uses CO2 as the working fluid instead of water. It actually makes the turbine smaller and adds 5% – 10% to the efficiency for an end product that can be over 50% efficient compared to the 35% – 45% of steam versions.

ITER was supposed to be in operation by 2016 and cost less than 10 billion dollars. Now it won’t operate at all until 2035, and we won’t see any D–T experiments until well past 2040 — and of course, those dates are subject to revision (very likely, considering the project’s track record). And the costs? Nobody knows the real numbers; they are a well-guarded secret (probably because they’re embarrassing for ITER management…). But good estimates put the final construction cost in the 100-billion-dollar range. And then there will be the operational costs, which will be enormous. So a project that should have started delivering results ten years ago, at a reasonable cost — and that might have had some merit (although it’s debatable whether it was the best strategy from the beginning, but let’s leave that aside) —has become a doomed effort: poorly designed, even more poorly managed, arriving far too late and almost certain to fall well short of its promises. It is remarkable—though hardly surprising—how those involved continue to project an air of accomplishment, much as their predecessors did. After all, everyone has families to support and generous pensions to protect.

EVERYTHING comes down to energy. Make energy cheaper and safer and everything else gets cheaper along with it… setting aside corporate greed and all that. Humans are TERRIBLE at labour, and I mean that compared to every other animal on the planet.. even insects. We excel at using our brain.. thats what we evolved to specialize in. The cheaper and more accesible we can get energy, the cheaper it becomes to produce and operate automation tools that produce the things we need to live CHEAPER. All of these price increases on the basics is corporate greed… PERIOD. Look at a graph of the inflation accounted cost of various different products and ALL luxury items have fallen off a cliff while ALL basic needs have been driven up a mountain. That’s no coincidence, and it has nothing to do with developing an objectively superior energy generation system.

helion thinks they’ll have it by 2028. i’ll believe it when i see it.
@beyondfossil
May 26, 2026 at 5:08 pm
I’m with you. Helion will not even come close to their claimed 50MW production fusion power plant by 2028! Not even by 2038 from their current design, or ever.
Worse, Helion will be an ultra-hyped failure and yet another black eye for the fusion research community, which then hurts fusion’s credibility worldwide. The fact that Sam Altman is a major investor and on the board at Helion tells us a lot. Altman has a pattern of overhyping to get funding and is apparently good at selling snake oil.
@beyondfossil
May 26, 2026 at 5:11 pm
…continued
In the end, Helion trades the problem of sustained burning plasma for larger challenges of pulsed fusion. But pulsed fusion faces titanic challenges in recovering large energy peaks from such short-lived pulses at 1Hz. The actual fusion occurs in just microseconds, so it can produce millions of amps of current. That will absolutely wreck their equipment, as the high di/dt produces extremely strong Lorentz forces that physically kick the cables and capacitors. Then they need to perform these pulses 86,400 times a day, every day, to maintain their stated goal of a 50MW fusion power plant.
But they don’t even get to that part because they don’t have the necessary fuel. Instead of the typical tritium, Helion uses an extremely rare helium isotope, He3. But this fuel mixture requires _multiple_ times the heat to fuse at temperatures already insane for tritium, at 100 million ℃. There’s no way they can create the amounts of He3 by 2028. Even if they did, they’d be in a deep hole of money and energy. But the whole point of a fusion power plant is to create both net positive energy and revenue!
@beyondfossil
May 26, 2026 at 5:13 pm
…continued
There are further problems down the line, too many to mention here. But a fairly obvious downstream problem is that Helion’s 1Hz pulsing on the grid will destabilize the grid through frequency & voltage ramping and harmonics. No grid operator will allow such behavior on their grid, and Helion has not addressed how they will smooth out their power flows. But it would require a warehouse full of very expensive capacitors to even come close, all while they take a nonstop beating. You can tell Helion isn’t even planning on success in 2028, but just getting funding.

I fully believe that we should already be utilizing Nuclear energy by now. Too many people think of Nuclear energy as something negative but our capabilities have massively improved. So many areas of the nuclear sector have improved, it’s just not commonly known. There’s so much potential with-in nuclear energy just sitting there, not being used. I hope the US will embrace Nuclear energy because it really could improve our future. We are using alternative energy options but a lot of our energy grid is still dependent on fossil fuels. Humanity will be better off once we commit to a new wave of modern advanced nuclear energy options. Our government has been holding us back. They’ve been way too restrictive. They won’t change out dated Bureaucratic hurdles that are one of the biggest things that is blocking progress within this energy sector. This stuff has been blocking the progress of our energy grid for decades now. They don’t directly say it out loud but it seems like America wants things to stay exactly how they are right now. So our government has found creative ways of making progress a nearly impossible achievement.
People keep saying: “If Thorium reactors really are amazing, then why don’t we see them anywhere?” ~The reason that’s true is: Here in America we have blocked our progress with a unadaptable, outdated regulatory system & they have repeatedly denied the approval of nuclear permits.
I hope we start using Small Modular Nuclear Energy options because it will help provide power for projects out in remote locations that are currently completely dependent on diesel generators ⛽
Additionally to nuclear power, Having Fresh water is one of the most important things.. So we should build desalination plants in areas that need it & power it with nuclear energy. I know desalination demands a lot of energy so we could utilize nuclear energy to provide energy for desalination. The potential for positive uses is massive.
