Nuclear vs. Solar vs. Others

For Calliban re Post #297

I agree the article at the link you provided is interesting.

Curiously, the article did not use the word "antimatter" (or if it did, I missed it despite careful reading)

I am left unclear on what is happening in the scenario described by the authors, and hope you might have insight(s) to help....

If the authors ** are ** talking about antimatter, then I am guessing they are using a laser to convert one of two protons to an anti-proton, and then reaping the energy released by combining the anti-proton with a normal one.

My expectation is that it will take energy to convert a normal proton to an anti-proton.

From the Rob Peter to Pay Paul school of thought, I would expect it would take "quite a bit" of energy to convert an ordinary proton to an anti-proton.

A natural question that follows is: does it take more energy to convert a proton to anti-proton than is released by the annihilation event?

One possibility is that these researchers have found a way to create anti-matter (anti-protons to be specific) using lasers.

If ** that ** is the case, and if those anti-protons can be stored (somehow) then they might be enlisted to provide propulsion at a later time.

I am reminded of a concept articulated by JoshNH4H shortly after I joined the forum. He had pointed out that if electrons are removed from protons, as is the case with many particles arriving from nova events in the form of cosmic rays, and if those protons could be stored somehow, they would be a source of energy when they are allowed to collect electrons. The challenge then, and now, is how to store such protons. They would repel each other vigorously (of course) and they would be thirsty for electrons, so would steal electrons from any normal matter with which they came in contact.

We did not solve the problem before JoshNH4H returned to Member status in the forum, and it remains unsolved.

The topic was: http://newmars.com/forums/viewtopic.php?id=8756

The challenge of storing anti-protons for an anti-matter drive is even more severe .... They are just as thirsty for electrons as the ordinary matter protons, but ** these ** little critters are capable of merging with ordinary protons to make lots of particles.

And the sequence of thoughts above leads me to wonder if a container made of ordinary protons without electrons (the vision of JoshN4NH) might be able to hold a stash of anti-protons due to electrostatic repulsion. The container would be a good description of an accident waiting to happen.

Speaking of JoshN4NH, I just checked, and discovered he's logged into the forum as recently as February 7th.

Last visit: 2023-02-07 20:38:01

So! Following up on the previous post ... I had provided a possible solution to the challenge of storing protons without electrons, but JoshNH4H did not enthuse about my discovery. However, I would like to return the storage method to view.

The storage method is recorded in the archive, shortly after I joined on 2018, when JoshNH4H was still active.

It was a magnetic storage system for ions to be used for experiments. I had found a report about the storage system, and the link to that report should still be in the archive. A search for the topic discussion might include author=joshnh4h and tag=proton or author=tahanson43206 and tag=magnetic.

JoshNH4H was active in 2019, where his posts show exchanges with GW Johnson, kbd512 and OldFart1939 and others

http://newmars.com/forums/viewtopic.php … 31#p158831

The link above from 2019 appears to be in approximately the right area. JoshNH4H is replying to kbd512 about his ionized atom energy storage concept.

My reply would be nearby. My reply contained a link to a magnetic ion storage system.

Here is the topic: http://newmars.com/forums/viewtopic.php?id=8756

TH, we do have something like what you are describing. A capacitor. It stores an electric potential difference across a dielectric. The problem with storing charged ions, is that you inevitably create electric fields. These would eventually grow strong enough to tear electrons from your container, even if you could hold the protons in a magnetic field. It is voltage gradient that matters here. So a magnetic trap would only buy you a limited charge density before the voltage gradient strips electrons from any matter that is close to it. Even the best insulator has a breakdown voltage.

For Calliban re #303

Thank you for your observation about the probably low density of charged anti-protons in a magnetic field. That observation matches pretty well with what I remember of those of JoshNH4H back in 2018.

The issue at hand is storage of antiprotons for a space drive application. I do not understand the original article found to be sure, but I ** think ** the researchers were reporting on finding a way to make antiprotons using a laser beam. The evidence they cited was the observation of energy output that would be consistent with an annihilation event after a normal proton had been converted to antiproton, and then combined with another normal proton.

That observation in itself is primarily of academic interest.

However, perhaps there is a way to make antiprotons using laser beams. If such antiprotons could be collected and held for a period of time, then they might be harnessed for a high power deep space drive, which would make achieving 10% of light speed practical for a probe to a nearby star.

The density of magnetic storage would necessarily be low, but the energy cost of such storage would be low, so low density storage of high energy particles would (presumably) be worth while.

Since you have not yet read the original article, I ** think ** the method used was rotation of the ions to be preserved in a magnetic field. My recollection is that the storage system was a kind of drum, in which the ions moved about a central core while waiting for being drawn off for an experiment.

If such a low density storage system is possible, it would be ideal in space.

if a space vessel is driven away from Earth by such a propulsion system, it could spend the flight time building back up the store of antimatter protons, for use to slow down at the destination.

It is rather ironic that these boondoggles will be forcefully subsidised under the 'inflation reduction act'. Everywhere else that has attempted a mass buildout of intermittent renewables has seen large increases in the price of electric power. Rising energy costs have a long history of driving up inflation and causing recessions.

Calliban,

It's not "ironic" if your intended goal is to destroy the American economy so that the majority will remain subservient to your every whim and fancy. The Democrats do this stuff intentionally. It can't all be chalked up to stupidity, despite how insufferably dumb most of them are. The Democrat Party is an actively malicious organization that spares no attempt to undermine the American people, our economy, the nuclear family, and now they even support active participation in wars against nuclear armed nations like Russia. That combination of factors makes them a malevolent cabal of cretins. When President Trump was in power, they encouraged seditious activities. Now that President Biden is in power, they're cracking down on their own seditionists. Their useful idiots served their purpose, but now they need to be dealt with.

Calliban · 2023-05-15 16:01:43

Sadly, that appears to be the case. These cretins don't seem to care about the wellbeing of people. They are just seduced by what they consider to be beautiful ideas. We saw where that led in Soviet Russia. Individual lives end up not mattering if you are more about ideas than people. And they probably realise that succesful people don't vote for them. So their goal becomes keeping the proles as downtrodden and embittered as possible.

The great men that pioneered the atomic age knew that we couldn't go on burning fossil fuels forever. By the early 1990s, all of the technology was in place for closed fuel cycle fast breeder reactors that would have freed humanity from energy scarcity for about the same cost MW for MW as a light water reactor. Destroying the IFR programme was one of the first things Clinton did in office. The far left knew that no one would bother pouring money into wind and solar if utilities could buy nuclear powerplants that were almost perpetual motion machines. So they made damn sure it was buried.

kbd512 · 2023-05-16 11:40:24

Calliban,

It's worse than that. They've been taught to loath themselves by the cretins of society. Someone who loathes their own self can never love others. It's a very dark place to be, and a far more serious problem, because it's one that only they can solve and an increasing number of them can't seem to solve it.

It's wrong to believe that people who you define as "successful", also view themselves that way. The rational goal that otherwise insane people will have is to destroy that which they believe is the source of their problems. When you've come to believe that you're the source of the problem, because that's what you've been indoctrinated to believe by evil people, anything is possible. That's nihilism. We can identify the myriad of ways in which the communists failed, but ultimately nihilism is the root of the problem.

The common denominator amongst the Democrats and leftists I've personally interacted with, is that many of them are deeply unhappy with themselves, their lives / decisions / outcomes, and none of them know how to resolve whatever they think is holding them back. They search for external reasons why their lives are not what they wanted, but eventually that loathing gets turned inwards.

Like I said... It's evil ideology. Nobody is born believing this nonsense. It has to be taught to them by ill-intentioned people who they trust. Teaching someone to hate being who they are is about as great a betrayal of trust as is possible. It's perfectly understandable why it's so hard to recover from that.

Georgia nuclear rebirth arrives 7 years late, $17B over cost. Two nuclear reactors in Georgia were supposed to herald a nuclear power revival in the United States. They’re the first U.S. reactors built from scratch in decades — and maybe the most expensive power plant ever.

https://apnews.com/article/georgia-nucl … 9115e88a64

Expanding the Vogtle nuclear power plant in Georgia with two new reactors has turned into a financial disaster for the utility, state and customers. It has also literally bankrupted Westinghouse, the primary contractor.
Unfortunately this isn't the only new nuclear project in the US and Europe suffering from similar massive cost overruns and schedule slips. That is a primary reason why the industry has been in decline in this century. According to the article 24 other reactor projects proposed have been shelved as a result, including one in South Carolina that was partially built and $9 billion had already been spent on.

Japan will try to beam solar power from space by 2025
https://www.engadget.com/japan-will-try … 38244.html
Japan and JAXA, the country’s space administration, have spent decades trying to make it possible to beam solar energy from space. In 2015, the nation made a breakthrough when JAXA scientists successfully beamed 1.8 kilowatts of power, enough energy to power an electric kettle, more than 50 meters to a wireless receiver. Now, Japan is poised to bring the technology one step closer to reality.
Nikkei reports a Japanese public-private partnership will attempt to beam solar energy from space as early as 2025. The project, led by Naoki Shinohara, a Kyoto University professor who has been working on space-based solar energy since 2009, will attempt to deploy a series of small satellites in orbit. Those will then try to beam the solar energy the arrays collect to ground-based receiving stations hundreds of miles away.
