Claiming over-unity in the core reaction when the only thing that matters for power generation is over-unity for the entire power generation system is extremely annoying.

What I want to know is this: if I could build one of these devices in my backyard, what percentage of the input power required to run the device is the output power that I could use to run my home?

Right now, that percentage remains firmly in the negatives. If they ever get that number into the positives, we can start to argue over the cost per kWh compared to other energy sources.

It reminds me a little bit about CERN and their wailing about how we simply must build the FCC, after confirming the Higgs with the last mega collider and not much else.. Every Physicist has their favorite axe to grind, and they seem prone to histrionics at times.

We can gush about Qin to Qout of >1

We can when they gain another couple of orders of magnitude efficiency, anyway. They need that before they can claim to have gotten there, because they're counting the energy output from the lasers as the input to the system, but those lasers don't fire for free.

Exactly.

I think the best way to employ fusion power is using the source around 93 million miles away from us. It's unshielded, but pretty reliable and those solar panels we keep putting online seem to work pretty well.

The biggest problem that fusion, and indeed fission has to a smaller extent, is that as time goes on, other energy sources are making them superfluous. Deniers might say otherwise, but if we go back say 25 years to now, they have had to move the goalposts many times.

Every time I get the urge to upgrade my pc I ask myself, "Does it run everything you need to and reasonably well?" Yup.

My most recent upgrade was pretty recent - I bought a Mac mini M4. The speed increase was significant, and the form factor was a big part as well. Plus Apple had a good trade-in for my old Mac.

On the Windows side, My laptop is 5 years old, and fits your description of running what I need it for. It is edging ever closer to getting Linux on it.

What matters is not net positive - which isn't anyhow.

Qin to Qout is nice and all, if you put in a megawatt of power into the device, and get a megawatt plus a watt out, that's nice. You've achieved gain.

But for all of the gushing over how we finally are on the way to the cleanest, safest almost unlimited power that we've been promised is right around the corner, there is a real problem.

Qtot.

Qout doesn't mean much if the total mount of power needed so far exceeds the output of the fusion device that it still isn't practical. There is a tremendous amount of power needed for generating all that peripheral or "parasite" power. Cooling, laser generation needs to name some. And it only gets worse when we try to make this happen continuously, not for just a very short time.

And then there is the non-abundance of Tritium - another issue. We're probably still going to need fission reactors to provide the needed tritium.

We can gush about Qin to Qout of >1, but Qtot is still something around .01.

I used to joke that if we are to ever get actual fusion power, we're going to need a huge fission reactor built onsite to provide the power needed for the fusion reactor, as well as provide the tritium needed.

Then I realized that my joke was serious.

Then I realized if we have to build that honkin big fission reactor, why not just use the power generated by it, and skip the fusion part? You'll get more power to use.

Some don't want to hear this stuff, but it's not wrong.

1. The people in question are not stuck. They live happily. 2. Those systems work like clockwork. They don't usually need replacing.

This one get it.

Business is not generally in the Replace everything to get nothing more than we already have mode.

IT guy goes to see the accountants...

"We need to replace all our computers for a cost of A million dollars." CAO "Oh goodness, did something happen?"

IT - Oh no, there are just new models coming out."

CAO - "But did the old ones quit working? What are we getting for that million dollars?"

IT - "Well ,they'll just do the same thing we've been doing for a couple decades now - then again, we're going to need about 200 K to rewrite some software that won't run on the new ones."

CAO - So we're actually going to spend a million to get less functionality, and have to rewrite functioning software to get it to function on the new computer system? That's a really hard sell!"

IT - "Well, when you put it that way."

A lot of business savvy people still aren't used to the perpetual upgrade, nothing added cycle. It might seem like a black hole you throw money into.

I work with plenty of people who are vegan for religious and cultural reasons. They will bring it up at opportune moments, we're discussing where to go out and they'll ask if there are any vegan options at the proposed restaurants. Then there are those who "discovered" veganism and form who being vegan is the religion... they will let you know it any chance they get and will generally question your dietary choices as to boot. I believe the poster was referring to the latter.

Yeah, on campus, most of the vegans tell you as a flex. And a fair number are insufferable if you eat in their presence. This is the experience with one who worked in our group, but it isn't unique.

Our group used to do a weekly group luncheon. Then we hired a vegan. Let's call her Connie. She had issues.

So we adjusted at first. Tried to go to places with vegan options. But Connie grilled the waitstaff and managers. Nothing that ever touched meat or milk or eggs or cheese could ever touch anything she ate. It seriously took up half of lunch for her making certain that her veggie only purity was met.

Then when the food came out, she'd berate us savages "Ewww, how can you eat corpse food". "You know you are killing yourself, don't you?" She turned the group lunches into an unpleasant chore.

So the males in our group decided to stop going to these luncheons. The ladies at first didn't want to upset Connie, so they went a few more times, but it was pretty clear that group lunches suddenly became women only, and even they got tired of Connie, so that was the end of group luncheons. Connie was simply too abusive.

For a while.

Connie ended up leaving to move to California. We had a going away party. The day after Connie left town. I treated everyone to Cheeseburgers and Cheese Fries.

Until dear Connie tested our endurance, I was pretty ambivalent towards vegans. After her and a few others with the same issues showed up, I had no use for them.

Oddly enough, Vegetarians don't present the same issues. I even tried vegetarianism for a while, but it wrecked my metabolism, and took a year to get back to normal. Some people can't handle it.

I woke up with tinnitus while having Covid. Several days in without any severe symptoms and then just woke up with some solid ringing around 12khz sound that never ends and is made worse by loud sounds like wind, or a shower, or engine. That was two years ago and I have still had it every day since then but my brain has gotten better at tuning it out. Guess that was the last time I’ll hear quiet again but at least it’s only shot out my high range hearing over 10kHz which is normal at my age I guess, just not the happening in a few hours. So basically It’s annoying but does not interfere with my hearing much. When I was tested the audiologist said they were getting multiple people a day every day with similar problems.

I had something similar after catching mononucleosis when I was 18. I also had hearing damage from when I was. child and that came from the mumps.

Anyhow, the tinnitus didn't happen until after the mono. At first it sounded like a million birds chirping, and now it has added either a lawnmower sound or a diesel truck idling outside the house. At this time, I don't hear much over 3 KHz. Other than the tinnitus which can be of any pitch.

The HHS secretary lied. The plaque hypothesis is still strong and valid. Citing one fraudulent study by someone desperate to get their PhD or whatever doesn't mean everyone studying Alzheimers is a liar. The nuance is explained here, try to understand it. http://www.alzheimers.org.uk/...

Were you replying to me? That does not answer my question that despite the US as some people claim, suppresses the real cause and treatment of Alzheimers.

Why has the rest of the world not cured Alzheimer's? We're only 350 million out of 8 Billion. Why? If we are wrong, others will be right.

Sorry to say, you are massively over-estimating the impact of these drugs. The NHS decided not to fund donanemab back in October. That’s because, despite being best in class, it produces a six month slowing in progression of memory deterioration. What does this mean? If you start on the drug at, say, age 75, then by age 80, you’ll have the memory loss you’d otherwise have had at age 79.5. It has zero effect on every other symptom, including those that can be more distressing for everyone than the memory loss, such as apathy.

Alzheimer’s is a shitty disease. The progression is what it is. It’s not modifiable, by exercise, good living, drugs, using your brain or anything else.

And the attention these drugs get is a massive distraction from having to confront the actually hard work of both population-level prevention and providing compassionate well-funded services for those in need. Arse-wiping is a lot less glamorous than drugs, but it’s very much needed.

My background in all this is that my m-i-l also had AD (although she died of mouth cancer), and I am lucky enough to have one of the UK’s most senior dementia doctors as a good friend, so I asked him to tell me the blunt truth, and he did.

Some people are so terrified of death, that they think that extending the horrors of Alzheimers are a good tradeoff. I mean, living 20 years with it is great - or perhaps not.

The decomposing brain doesn't just make people forget who they are, they slowly stop the very processes of staying alive. Organs slowly shut down, Bowels stop working correctly and muscles atrophy. You end up not being able to walk or speak, and end up on antipsychotics to try to level you. Some people become happy demented, but a majority are quite unhappy.

And it is absolute hell on the family.

I have absolutely no intention of inflicting that on my family.

When I was a child, my grandmother had "hardening of the arteries" as they called it. She became demented. But such a difference. At that time, she was at home until things got bad, then when it wasn't possible to keep her at home, she went to nursing, and didn't last much longer. So rather than the 10 to 15 year dying process it was less than 4.

It was obvious what was going to happen. But it was over in a much shorter time. That to me is a blessing both for the patient and their families.

If I were to make a guess, the opportunistic causes of death in Alzheimer's patients will just have more time to strike when they spend longer in the final stages.

If a cure or an actual prevention is found, then the healthcare system can give me a call. Otherwise, thanks, but no thanks. No one gets out of here alive, and extending the amount of time a patient spends in nursing care to live a little longer without a mind only helps the pharmaceutical companies and Nursing homes. Miss me with that shit, life!

You and I have been over this before. Getting on preventative drugs sooner (before major symptoms start) means a longer window of lucidity before the bad part starts. Early detection is key to getting a few extra good years to spend living life before everything turns to shit.

We already know how to extend the shitty part, early detection means more good years.

Basically, your suggestions of morbidity on the early diagnosis of Alzheimer's are absurd.

TGYhe awesome part of your believing my ideas are absurd are that even if say they onset of symptoms is stretched from say 10 years to 20, all it is doing is allowing you to be in the last part for longer. I don't care if you think my ideas are absurd - have you lived through a loved on getting Alzheimer's. What's your plan when it gets to the point where they have to use anti-psychotics? I wouldn't even wish it on you, even though I don't like you. Anyhow, do as though wilt, and if you want to spend twice as long in end stage dementia, then do it and be happy about it. Do you prefer haldol or thorazine?

My own hierarchy is MacOS (UNIX) Linux (UNIX-y) and then if I have to, Windows. Guess which one takes up 99 percent of my troubleshooting time?

The eternal question is how can an operating system be so damn brittle that after all these years, it still isn't very good?
