There was a post back in 2012 (I know it is very old) titled “Is Muon-Catalyzed fusion possible with room temperature, gaseous Deuterium?” It addressed some of the major problems of producing energy with muon catalyzed fusion.Muon catalyzed fusion is the process of replacing one, or preferably both of the electrons in a Hydrogen molecule with a muon. A muon is a subatomic cousin of the electron. They are both leptons, only an electron has a mass of roughly .000511 GeV/c^2 and a muon has a mass of .106 GeV/c^2. Muons are roughly 207 times more massive than electrons. The muon has the same charge as the electron, only it is much larger than the electron. When it approaches a Hydrogen molecule it knocks the electron out of its orbit and takes its place. Because the muon is 207 times more massive the the electron, its orbit is 207 times closer. This brings the protons much closer to each other. Oridinary Hydrogen molecules have an atomic radius of 53 pm (53 picometers). That means the nuclei of hydrogen molecules are roughly 106 pm apart. The muon’s orbit brings the two Hydrogen nuclei 207 times closer. The resulting nuclei are roughly .51 or half a picometer apart. Hydrogen nuclei are close enough for quantum tunneling to then take over. The two nuclei fuse. The muon is then ejected out and hopefully lands on another hydrogen molecule. It will then knock the electron out of its orbit, replace it, and catalyze another fusion reaction. The process is then repeated until the muon decays. The muon however is unstable and has a mean lifetime of about: 2.2 microseconds. Now we get to the challange.
Solving these problems:a)the muon decays before it can catalyze a number of fusion reactions to break-evenb)some muons stick to the helium nuclei they have created, thus not allowing them to catalyze any more fusion reactions.c)He3 atoms that have already fused can catch muons that would have gone to catalyze deuterium fusion.
These look like three separate problems but they really aren’t. It all boils down to, muons are expensive. If they were cheap: a) who cares if it decays, they are cheap. b) who cares if muons stick to helium nuclei, I have a crap-ton more. c) who cares if He3 nuclei steal muons, I have a crap-ton more.
It all boils down to: where can I get some muons that are easily to make, plentiful, and cheap. This was explored in the thread I mentioned earlier: “Is Muon-Catalyzed fusion possible with room temperature, gaseous Deuterium?”Muons are created when solar wind strikes particles on Earth’s atmosphere. They are generated roughly 15km above sea level. They rain down on Earth and go straight through everything. They are generated with roughly 6 GeV of energy and lose about a third of that and hit Earth with 4 Gev. Ordinary matter has trouble absorbing muons created in Earth’s atmosphere as those muons are moving at roughly 98% the speed of light. At around 300,000,000m/s with a mean lifetime of 2.2 microseconds they should only travel 660 meters. Despite their short half life their time dilation keeps them alive long enough to hit the ground in detectable and significant numbers. Muons can even be detected several hundred meters underground, although not very well. The Soudan 2 Detector has detected muons underground, however the rate of detection is less than that which is hoped for. According to The Sudan Underground Laboratory: “On the surface, a detector the size of your hand would detect about 2 muons per second. Down in the lab, 1/2 mile underground, that same detector would detect about 2 muons per week.” which is crap. However 1 muon per square centimeter strikes earth’s surface per minute. We know most muons are getting past us.So this is my idea:a giant pole.A vertical LINAC is built at a significant altitude above sea level. Deuterium atoms are ionized and their nuclei are shot downwards at roughly 98% the speed of light. Muons penetrate the LINAC and since they are traveling downward at the same speed of the protons they are stationary relative to one another. The tube which they travel down will get progressively narrower bringing the molecules closer to one another, allowing muons to jump from one to the other with more ease. Protons and muons will attract one another because of their opposite charges and form a Deuterium molecule, and fusion is catalyzed. The deuterium is then brought back up to the top for another pass. Not all muons strike Earth vertically. Only about 66% of muons are vertical, the rest come at an angle. However 6600 muons per m^2 per minute is still a lot. Those that come in at fairly small angles still have a chance to be absorbed. I know it is a lot more complicated than that. You would need to contain both the proton and Muon, the neutrons resulting from fusion and then somehow figure out how to absorb the energy. It is a huge stretch, to put it mildly.

You can patent it.
If the idea is one day old, you did not do the math, that would take much longer. Fusion is complex, and it has hundreds of challenges you probably did not even hear about.
"I just thought of something" is not an interesting new concept. It is probably something hundreds of others thought about, then did the math, and saw that it is not viable.

Unfortunately this attitude, I have found, is common among people who don't know how research works. They often claim to have a grand idea (not backed by math) which they're scared of someone stealing. If your idea is a success, the chances are very slim that it gets stolen. If your idea is obviously not good to someone inside the field, you also don't have to worry about it being stolen.
Did you read any relevant literature in the field of nuclear fusion? Do you have a physics background? Do you know specifically what the technical challenges are in creating nuclear fusion right now, and do you have ideas to overcome those specific technical challenges? Why do you feel your idea is superior to everything else that has been tried, especially since you have no math behind it? These aren't things you have to explain to yourself--these are the questions the scientific community would ask that you must be able to answer, or else no one would take you seriously.
Regardless, ideas are a dime a dozen, and if you can't quantify your idea, if you can't put some math behind it, get a prototype, etc., and if someone else happens to come up with the same idea and does that stuff, then you did not come up with it. Sorry, like I said, ideas are a dime a dozen. Implementation is the important part. Einstein didn't just make two postulates and stop there--he did calculations using his ideas.

And worse, that these stinkers are circling like vultures, ready to steal this idea.

Understandable! I think the nuclear fusion researchers are out of ideas since years. Researchers at the Tokamak are now required to full-time browse the internet for some individual who has a novel idea on fusion. Not just any individual will do though! They specifically want those who have no science background and who did not have time to do the math. Those are the ideas that the fusion researchers are looking for!
All I want to know is: Is the concept is viable or not, and if not, why. I don’t need mean sarcastic vultures. I am 15. I know I am naive and stupid. But I am also curious and I want to learn.
mfb and some other guys had a thread about this a while back. I just want to know if the idea of accelerating protons to the same velocity as muons would allow more muons to be absorbed. Here is that thread:
