As I've just mentioned, the Apollo program is an object lesson of what happens when continuity of development and experienced people is lost. It is impossible to record every single little bit of critical knowledge and techniques that is contained within experts minds from any given period.

If you decide you need fusion, however far away we currently are, you would have added extra years to reaching the end goal, since you’ll have to duplicate previous work. That is an interesting point and incidentally something that I feel is happening in e.g. the area of microbiology. DNA sequencing has become so cheap and attractive that is has displaced traditional microbiology from many areas of research and very few younger scientist learn the many tricks you have to do to e.g. cultivate tricky organisms. As a consequence, we have vastly increased our knowledge regarding what is out there (or rather, whose DNA is out there) but our understanding of what they are actually doing is slowing down quite a bit. Somewhat strangely, this also seem to affect the literature. One would assume that once it is out there, knowledge would not be lost, but I do start to see a fair bit of newer publications that apparently ignore or are simply unaware of many older publications, resulting in repeating the same insights, just repeated with more sequencing. I suppose it is not unusual that the shiny next new thing can affect science and research directions but if putting things on backburner results in generational gaps, the impact seems indeed outsized.

If there was an impasse or outright failure, sure, continuing would be the sunk cost fallacy, but knowledge diffusion is a real thing, even in programs that aren’t being cancelled. Some key person retiring or dying can impact a program. Researchers are not interchangeable parts. 1 hour ago, Ken Fabian said: More than 70 years so far and still not even close. If any program were closing in on a working reactor then yes, breaking it up will put the overall goal behind, but that is not the case. That’s not the case, though. It’s progressing. There’s no guarantee that a working, net-energy producing reactor will ever be built, but there’s no denying that the state of development is beyond where it was, say, 10 years ago. EAST, NIF and KSTAR have each set some kind of record of a fusion parameter in the past few years. And let’s not forget that the premise here is that there is some ethical issue because of the “vast” amount of power that fusion programs use Link to comment Share on other sites More sharing options...

Why is there so many failures occurring at launch presently if that was the case? All that elementary launch stuff would be nailed down pat by now if there had been continuity and recorded.

Do you think they simply haven't thought deeply about this subject and you are clearing things up for them? Or perhaps you can convince them to spend money they do not have? It was always a long shot, bc money now is more persuasive than life tomorrow. Australia has the natural resources to supply its own nuclear program virtually free, but for some reason the top brass didn't like that idea. They're an example of why I put this question in ethics. 11 hours ago, StringJunky said: Why is there so many failures occurring at launch presently if that was the case?

But in the case of fusion, there hasn't been any successful launches; so what would be wrong with letting Elon and his cronies take the reins, leave the public fund's free to help in a more productive way 🤞.

If your issue is the ethics of Australia rejecting nuclear power you should have posed it that way. But you didn’t. What is unethical about fusion research? 1 hour ago, dimreepr said: But in the case of fusion, there hasn't been any successful launches; so what would be wrong with letting Elon and his cronies take the reins, leave the public fund's free to help in a more productive way 🤞. No R&D effort has had a successful launch before completion. If you’re going to criticize it, at least use the same standard. It’s like complaining about not breaking the sound barrier before Yeager did it. Link to comment Share on other sites More sharing options...
ImplicitDemands Posted July 1 Share Posted July 1 (edited) When the only think tanks capable of figuring out how to get enough energy back to perpetuate a fusion cycle aren't paid or respected enough to even bother to write more than hints much less go through the process of getting it patented, then yeah. In this economy? With this "incentive"? Yeah, kiss it goodbye. The group are idiots, yet we run on a census. So the majority just tries to make everything bad for the ones that are talented enough to help because they stew in their own collective failures making sure there are no exceptions.

What is the definition of a census? Rule by majority. A number value ($) is insufficient for exchange. Without a negotiation on terms, there can be no real trade outside of the bottom line ($). Quality of life is more complicated than an arbitrary number ($) can provide. Discussions on ones terms of living are not made in this or any other country, everyone is subject to the wrath of the census.

Actually, the definition of census is an official count or survey, most commonly related to the numbers within a given population.

It doesn't seem like it. I commented on your post because you claimed the majority are focused on making things bad for the talented people. I think they are focused on making things better for themselves. If that makes things bad for you, it's a consequence, not a focus. I don't know how this ties to what you posted above.
