The amount of energy required to make a stable elements like boron, lithium and nitrogen become unstable is the same as the yield energy. Thus, fusion doesn’t gain any free energy from this exchange. Therefore, it is impossible to gain free energy from a stable element because it is against the laws of thermodynamics.

I had to pause reading your nonsense right there.
Since your premise is so vastly flawed, you cannot possibly even stumble upon an accurate conclusion.

Look up nuclear binding energy, as JimmyT so helpfully posted.

You are probably confusing the concepts of thermodynamics that suggests that certain stable “molecules” cannot yield any net positive energy from chemical reactions. Like with H2O and the countless charlatans who claim to get energy from water. You may be confusing the term “stable” as well. Stable may refer to an element’s inability to decay by spontaneously emitting certain particles. But this has nothing to do with whether or not energy can be extracted from a nuclear reaction.

In nuclear physics, the only element incapable of yielding net positive energy in a nuclear reaction, is Iron (Fe) 56. Generally, anything lighter can be fused to yield a net positive energy. And anything heavier can fission to produce a net positive energy. The rule of thumb is that the farther away from Iron the element is, the greater the yield.

Fusion beyond Hydrogen and Helium, as a net positive energy producer, is already witnessed in countless stars using spectroscopy. See stellar nucleosynthesis
They have proven that all sorts of elements undergo fusion to produce greater and greater amounts of energy. From Hydrogen and Helium… to Lithium, Carbon, Neon, Oxygen to Silicon.
Only when a star goes nova, does it return energy with a net negative reaction, producing elements heavier than Iron.

Here on Earth, we have witnessed several kinds of nuclear fusion too. Fusion with elements like Boron have already been done using laser pulses. We already know the yield of the reaction is greater than the input. But in the lab, we cannot yet focus the input energy with enough efficiency, and wind up wasting most of the energy without getting it into the reaction. The reaction winds up being net positive, but the experiment as a whole is not.
Also, we are still quite far away from creating the conditions for a self-sustaining reaction. Right now, the net positive energy coming from each pair of nuclei undergoing fusion, doesn’t get put into the next pair’s reaction. In a star, gravity creates a density that ensures the reaction continues.

This is mandatory reading for anyone, such as yourself, attempting to speak with such authority on the subject of nuclear science.

I will not indulge your ramblings on Aether. As everything you’ve posted, your links included… point to pseudoscience woo.
The very minimum of scientific process isn’t followed, and the extraordinary claims which propose that so many tested theories of science are wrong… require equally extraordinary evidence which is lacking. Do not respond until this Aether hypothesis is properly peer reviewed, because it is certainly far from credible as of today. And don’t even think about using the Galileo Gambit here… it is cliched, weak and doesn’t work.

I have noted that scientists on this website are all too eager to demonstrate how much energy they get out of a fusion reaction and are very reluctant to admit of or include how much energy was expended in creating the reaction.

Note – When calculating the total energy cost please include –

1. The mining energy expended in obtaining the raw materials.
2. The energy cost of building the fusion reactor device.
3. The electricity used in destabilizing the stable material.

After all these costs have been added up – Is the energy obtained from the fusion reaction greater or smaller that the total energy expended in making the reaction happen?

Note – After more than 50 years of experimentation of fusion reactions, no research team has ever gained more than an equal amount of energy to that what was required to initiate the reaction.

Thus, up until this very minute, I am infinitely more correct than what you are in this matter.

In regards to the aether. How do gravity waves travel through space and manage to squash space as the waves travel. What in the hell are these waves squashing? Note – Please don’t say “space” or I will fall over backwards! lol
