It won’t work until after the believers in Christ have been taken home. Then you’ll have the biggest working fake sun you could imagine.You’ll catch your lighting in a bottle alright…then…Abba Father help you all.

Thinking about ITER, I just shake my head. How much further could we have progressed if all of that money had been spent on something more advanced and more practical? The world’s biggest boondoggle?

Can you guys do a video on SPARC? It’s being run by MIT, and it isn’t open source like ITER, but I think it does show a lot of promise. They’re using a slightly different process: smaller chamber, hotter plasma, more powerful magnets.

with great tax funding shall come great auditing. This project is just a scapegoat for massive tax embezzlements. 8:27 even if the tech eventually works, it will hoarded by the rich to get even richer, not provided as a public resource. that is, unless we make a more equitable future.

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.

carrot on a stick, nuclear power works NOW, are they trying first to manufacture 0 gravity environment then use some other process similar power nuclear power could be doing now, all the funding we could have built how many Nuclear power plants? and some countries are attacking each other for oil and energy? we have 0 emissions alternative and instead we get windmills and solar farms killing millions of birds, and brainwashing unsuccessful campaigns? FF clean war free nuclear power will work NOW.

What an outstanding and deeply informative presentation of the material. There are so many aspects to this technology that are very difficult to explain in plain language but this presentation is wonderfully clear and concise. plasma physics was one of my concentrations in. college, and I feel smarter for having such a clear summarization. And, I feel like I’ve been there. An excellent piece. Thank you!
