You know the story of Lazar's element 115. Maybe a specific isotope of this element has dineutrons and can be controlled to release gravitational waves and to absorb ZPF energy (a flow of electromagnetic energy).
I have yet to meet a physicist who thinks that.

Lazar provided observations, that might be a realistic account of the facts.
That's a gross understatement. Lazar's explanations show a lack of understanding of physics which is absolutely astounding, as several physicists have explained.
He also provided explanations that are not convincing.
I don't think Lazar inspired true scientists to do anything but ignore his complete and absolute nonsense. Here is what Dr David Morgan said about Lazar pseudoscience.
So Lazar's story was a reporting/dissemination operation, intended to inspire true scientists for finding an acceptable explanation. Every scientist is inspired by observations. It may happen that some observations are very rare or unique...
After reading an account by Bob Lazar of the “physics” of his Area 51 UFO propulsion system, my conclusion is this: Mr. Lazar presents a scenario which, if it is correct, violates a whole handful of currently accepted physical theories. That in and of itself does not necessarily mean that his scenario is impossible. But the presentation of the scenario by Lazar is troubling from a scientific standpoint. Mr. Lazar on many occasions demonstrates an obvious lack of understanding of current physical theories. On no occasion does he acknowledge that his scenario violates physical laws as we understand them, and on no occasion does he offer up any hints of new theories which would make his mechanism possible. Mr. Lazar has a propensity for re-defining scientific terms, and using scientific language in a confusing and careless way. For these reasons, I don’t feel that Lazar’s pseudo-scientific ramblings are really worthy of any kind of serious consideration.
Lazar said it was impossible to make element 115 on earth, it couldn't be done, according to Lazar. Some apologists say he "meant" certain isotopes, but that's NOT what Lazar said, he made no mention of isotopes initially. After the synthesis of 115, Lazar started talking about isotopes.

We actually discovered Moscovium (element 115) back in 2003.

Lazar was just behind on his research ....
Maybe he meant element 215?
Virtually ALL isotopes of element 115 are predicted to be unstable. Pick any isotope from this chart of all the 115 isotopes, you won't find any that are predicted to be stable, since the longest prediction is for isotope 115310 with a predicted half-life of 4 days. Most half-life predictions are far shorter.

Well, regarding the above link, the synthesized 115 is unstable/radioactive. It cannot be the 115 isotope described by Lazar (possibly a 115 with different nuclear structure)
Even Haisch doesn't think 100% of the vacuum energy can be extracted. It's probably very ambitions to think even half of it can be extracted, but even if you could do that, which you very likely can't you would need to extract half the vacuum energy from 114 trillion olympic swimming pool volumes PER DAY, just to power your one average home. Maybe if Bernard Haisch's patent actually works, he could extract 1% of the vacuum energy, in which case you would need to process 100 times the 57.4 trillion olympic pool volumes per day to power the average home.
you'd need to extract 100% of the vacuum energy from about 57.4 trillion olympic pool volumes per day to power the average home.
I've seen claims to that effect. I don't know if Sabine Hossenfelder can convince you those claims are wrong, but I suggest you hear her out in the following video, where she explains the math starting at time 3:40, first going through general relativity where the energy density is based on observation. After that, she brings up the idea you mentioned aboout claims of enormous energy density, and says first of all they don't match observation, so the claims are wrong on that basis, and she further says the large energy density claimed by some is not even predicted by theory. If you think it is, then she challenges you to say which of our theories are proven incorrect by the fact that observations don't match the alleged "predictions". And she says you can't find any theories that are proven false, because they aren't predictions.

The extraction of Electromagnetic zero point fluctuations energy is a relevant and somehow unsolved approach to energy production.
Did you read your own source?

Nice discussion, but still wrong. As already stated, the predictions of quantum field theory are "predictions" because they correctly predict the Casimir effect.
en.wikipedia.org...
"Casimir effects can be formulated and Casimir forces can be computed without reference to zero-point energies. They are relativistic, quantum forces between charges and currents. The Casimir force (per unit area) between parallel plates vanishes as alpha, the fine structure constant, goes to zero, and the standard result, which appears to be independent of alpha, corresponds to the alpha approaching infinity limit," and that "The Casimir force is simply the (relativistic, retarded) van der Waals force between the metal plates."[16] Casimir and Polder's original paper used this method to derive the Casimir–Polder force. In 1978, Schwinger, DeRadd, and Milton published a similar derivation for the Casimir effect between two parallel plates.

You are obviously right. Let's say that the existence of em ZPF is a possible explanantion of the Casimir effect, and we consider ZPF like a reservoir from which we can get something real with an appropriate tool.
I hope we might agree that if we succeed in extracting ZPF energy and use it, then it exists.
It might not reside in our physical empty space, but be a quantum property of our "particles", keeping them in motion even at 0 K.
Whatever it is, I "hope" that the theoretical f^3 spectrum is correct, so that the dineutron converter will possibly work.
I wouldn't rule it out, I just don't think Casimir effect is good evidence for it as explained in your source, and even in that event we are not seeing an "enormous" value of zero point energy.

But the current thinking is if that's the zero point state, you can't remove any of that energy as explained here:

Paul A. Deck, assistant professor of chemistry at Virginia Polytechnic Institute and State University, gives a chemical perspective on this question:
"The zero-point energy cannot be harnessed in the traditional sense. The idea of zero-point energy is that there is a finite, minimum amount of motion (more accurately, kinetic energy) in all matter, even at absolute zero. For example, chemical bonds continue to vibrate in predictable ways. But releasing the energy of this motion is impossible, because then the molecule would be left with less than the minimum amount that the laws of quantum physics require it to have."
Exactly, it's a bad guess because we don't know how to properly solve for the correct answer. In the absence of being able to do the calculation, favoring the observed value of vacuum energy makes sense to me and doesn't contradict gravitational theory.

I take that as evidence that the supposed ZPF is an unphysical mathematical artifact, i.e. a problem made up by humans formulating a problem poorly, and not physically real.
Let me run through the 5 most common answers, explaining how people reach these different answers:
I've given you 5 answers to the same question (What's the Energy Density of the Vacuum?):
1. VERY CLOSE TO ZERO
2. INFINITY
3. ENORMOUS BUT FINITE
4. ZERO
5. NOT DETERMINED
Which should you believe? I believe 1) because it is based on experiment and fairly conservative assumptions about general relativity and astronomy. Answers 2)-4) are based on somewhat naive theoretical calculations. Answer 5) is the best that quantum field theory can do right now. Reconciling answers 1) and 5) is one of the big tasks of any good theory of quantum gravity.
Bernard Haisch's idea to extract vacuum energy wasn't to order them to be classical, but it seems to me he was arguing with the quantum fields, and I don't have confidence he would win that argument.

arguing with quantum fields and ordering them to be classical is like negotiating with cats.
A system is disclosed for converting energy from the electromagnetic quantum vacuum available at any point in the universe to usable energy in the form of heat, electricity, mechanical energy or other forms of power. By Suppressing electromagnetic quantum vacuum energy at appropriate frequencies a change may be effected in the electron energy levels which will result in the emission or release of energy.

BUT if a magical trick is able to increase the frequencies and make the emission of gravitational waves possible, and we believe that gravity is not quantized (this is a simplification...), what will possibly happen is that gravitational waves will be emitted and the ground energy level (electromagnetic) of the system will be immediately replenisced electromagnetically. So we cannot extract electromagnetic energy but we could extract gravitational waves in a NON traditional sense.
