content: Reclaiming Energy from the Magnetic Domain: A New Path ForwardIn late 2024, I began researching potential next-generation energy technologies — something that could one day surpass the limitations of lithium-ion batteries, particularly theirlimited energy densityand growingfire/explosion risks.Using AI tools like ChatGPT‑4o and Grok 3, I explored thousands of peer-reviewed studies in magnetism, spintronics, and energy conversion. My goal was to find a viable way tostore and release energy at the atomic spin level, not just chemically.Breakthroughs came from studies inspintronics and magnonics, where spin waves and domain behaviors are controlled via magnetic field pulses. Key examples include:-PIMM experimentswhereshort, high-current pulses launch coherent spin wavesin magnetic media (Lenk et al., 2011)- Amplified post-pulse domain oscillations in ferromagnetic nanowires (Hirohata et al., 2020)—⚙️ ExperimentsExperiment 1 – Domain Reflection & Spin CascadesA sharp high-current pulse into iron and Hiperco rods triggered coherent domain flips, withpost-collapse flux wavefrontsthat reflected at rod boundaries. These appeared as early magnetic solitons.Experiment 2 – Energy Harvesting via Spin CascadesWe tuned an LC tank circuit to match the rod's 5.5 kHz signature. When pulsed:- Input: 150 µF at 40 V (≈0.12 J)- Output: Rectified to ≈0.264 J into 40 uF capacitor for output voltage measurements- Observed2.2× energy gainover input-Coherent sine wave bursts followed the pulse collapseExperiment 2 – Original Notes and Oscilloscope Captures (PDF)Magnetic Preloading Breakthrough:When the rod was preloaded with N52 magnets (static field on each end), energy gainrose to 7×, supporting the idea that magnetic domain stress adds potential energy to the lattice.—📣 Call to ActionDozens of universities were contacted. Zero replies so far. So I’m turning to the builders, engineers, and physicists here whoactually try things.If you're curious:1. Read the papers2. Replicate Experiment 2 with and without static preload3. Publish or share your findings — support or challenge is welcomeThis isn’t free energy or perpetual motion. It’s controlledmagnetic energy releasefrom a domain-stressed ferromagnetic rod.—🧠 Implications if Scaled- High-output energy without chemical fuel or fire risk- Lightweight reactor systems, especially for mobile or off-grid use- Pulsed magnetic energy harvesting systems with solid-state reliability—🔗 Reference Links:•Spin Field Theory Paper•Experiment 1 – Domain Cascade Triggering•Experiment 2 – Energy Gain from Solitons•Experiment 2 – Notes & Scope CapturesRick BraddyRetired CTO | Independent ResearcherW5FCX – Amateur Extra

content: No, wait a second, guys.This time it is quite different. A demonstration device is proposed and properly described and it doesn't look too difficult to reproduce, so everyone can try it. Skepticism is fine, but before the device is independently tested and proved not working, calling BS isn't the right thing to do.p.s. actually, I'm not sure it is "properly" described. It would be nice to see some drawing and/or a photo in addition to the textual description to understand what we're talking about and make sure that whoever tries to replicate it does it the right way.

The rectified DC output (102–115 V) was confirmed using a DMM on the cap, but the waveform was underreported on the scope, likely due to attenuator loss or miscalibration.i will go back to verify the 10X probe attenuation mode.Thanks again — this helped catch something I missed.

content: Another no from me.I had a look at your first document "ASTM Experiment 1". It is a tiny sprinkle of data (two rows in a table) trying and failing to support several pages of ChatGPT opinion.Textual descriptions of high speed circuits are always inadequate and can give the impression that you are attempting to mislead or hide details about your experiment. You must provide drawn full circuit diagrams and clear, labelled photographs of your setup.Dismissing all classical explanations without thorough analysis, like the sentence "Classical inductive decay would typically complete within 1 ms under similar circuit conditions", read like "trust me bro don't look at that" arguments.It looks like your experiment involves measuring the primary & secondary voltages of a transformer using an oscilloscope. At a bare minimum I would expect to see pictures of these scope captures to support your claims.

On page 5 (not like a ham would need to get very far into this very thick book), we can see they have included the basic symbols, which includes a DC source.Lets assume our new over unity extra class at least made it that far in their studies. This suggests that their new cutting edge physics requires redefining the symbols. Or does reverse biasing everything create the magic they are suggesting?OP being a ham may enjoy seeing my homemade crystal radio to the left of the ARRL book which was used to demonstrate a diode detector in various environments. I am still waiting on Xena E to return to demonstrate some other mode that I am not aware of. It's not free energy but at least a little more grounded.https://www.eevblog.com/forum/dodgy-technology/can-reactive-power-be-recycled-fast-enough-to-power-resistive-loads/msg5942876/#msg5942876

content: Quote from: Analog Kid on June 16, 2025, 12:44:55 amAssuming the schematic they provided is correct, C1 150uF polarized cap is reversed through the intrinsic diode of Q1 and it blows up. If the OP does not know how to properly draw the supply symbol, I would assume there are many other problems with what they present. This would explain how they came to the conclusion that they created some over unity device. Still, with their ham extra class, I would have thought just maybe, they would know there's a problem.Unlike Xena E's request for scope shots of diode detectors, which was something any EE could setup and show. EEs know there is no over unity circuits, and no reason to spend time on it. Feel free to knock yourself out, but don't expect others to waste their time.

Yes of course it is not an over unity device as such, it is rather an energy harvesting device, but this leaves a possibility of demonstrating something viable "along the lines of", even if it is very unlikely.

But since, as was pointed out, a heat pump can actually function as an energy-harvestingdevice (thermal energy from the ground), isn't it at least theoretically possible that such a scheme could be used to generate electricity from this energy?Might not be efficient or even practical, but sounds possible, at least in theory.

content: It is always possible to generate electrical power by moving heat from a high temperature source to a low temperature sink but to get an effective output you need a sufficiently large temperature differential. Sources of environmental heat are simply not great enough to do this unless one lives close to a volcano, as is done in Iceland. Heat energy is a low grade energy with limitations on how much can be converted to other forms of energy. Electrical energy and kinetic energy are high grade with the ability, in principle, to be converted 100% to whatever form is required.

content: Quote from: Analog Kid on June 16, 2025, 06:59:42 amThis is an interesting topic, and one I haven't thought through before. But to put @Analog Kid's point in slightly different terms....A heat pump consumes 1kW of electrical power to produce 3kW of heat (1kW from the electrical supply, 2kW harvested from the outside air). Why can't we use 1kW of that harvested heat to run the pump, and enjoy the remaining 1kW as warmth for the house. Thus the device would run continuously with no input from mains electricity required. (Yes, I realise the pump won't be 100% efficient, so perhaps use 1.5kW for the pump and 500W into the home).This is not over-unity because heat energy is being extracted from the outside air.Now, I realise that this scheme cannot work, presumably for the reasons @paul cotter describes. But I don't think I really understand what the "grade" of energy actually means, and why it stops this system from working. Can anyone explain it in simple terms? Thermodynamics 101. 😁

content: Quote from: SteveThackery on June 16, 2025, 10:47:26 amBecause it violates the second law of thermodynamics.https://en.wikipedia.org/wiki/Second_law_of_thermodynamicsIt's not energy which does useful work, but potential energy, i.e. difference between energy levels. There's lots of heat energy in ambient environment, but it's impossible to use it for anything because it's in a state of equilibrium. The same is true of pressure. Think of the amount of energy there in 1m3of air, at atmospheric pressure, but it can't do anything, because it's all at the same pressure.In order to convert heat into work i.e. motion or electricity, there needs to be a temperature difference.It takes energy to move heat from a cold region to a warmer region.It takes energy, to reduce the pressure in one region and increase the pressure in another region.No, you can't use the 1kW of heat harvested from the heat pump to power it, because in order to use said heat, you need a temperature difference, which will be outdoors, where it's cold and that would require losing the heat.

content: It is possible to convert electrical energy to heat with 100% efficiency. Similarly it is possible to convert electrical energy to mechanical energy with NEAR 100% efficiency. Mechanical energy can similarly be converted with very high efficiency to either heat or electrical energy. Heat however cannot be converted to other forms with these high efficiencies and is thus considered a lower grade of energy. Converting heat energy to another form requires the use of a heat engine which uses a difference in temperature to do work. The efficiency of a heat engine, called the Carnot limit is the high temperature minus the low temperature divided by the the high temperature. From this it is obvious that 100% conversion would require an infinite temperature differential and a small differential would result in a tiny level of efficiency. This explanation in words is suboptimal and a review of basic thermodynamics would be a better course of action. PS: I just see that Zero99 has given a more precise answer.

content: I glanced through the bumf that came with the original post. Not having more than the most basic primitive knowledge of quantum mechanics a lot of the terms used conveyed little info to me and it all sounded very "wordy" to me, though I accept I could well be wrong. The scope shots looked to me to be normal ringing, the type I have often got with a hastily built flyback smps. I have no difficulty using magnetics for energy storage, as others have pointed out but getting more energy out than in puts this in the same category as Santa Claus and the tooth fairy.

content: One thing, @Joeqsmith:Are you claiming that their circuit will blow up just because they erroneously labeled the polarity of their power supply?If so, that's a pretty weak argument. They just need to flip that symbol. The rest of the circuit looks OK. (Of course, no idea what it would actually do, but that's another matter.)To the OP, you are aware that you used the standard symbol for a battery cell to represent your bench power supply, yes? (And it's even labeled to remove any doubt.) But you got the polarity backwards, which invites niggling criticism.If it were me I'd just indicate the power input by two input terminals, and label the+one just to be clear.

Won't go into them here.However, I hasten to point out that sometimes y'all over there have much more succinct words for things. My favorite example is what we call an "elevator": your term, "lift", is just perfect for this conveyance, much better than our 3-syllable-longer term. Thinking about our term I always wonder why we didn't go full Greco-Roman with it and call it an "elevatorium". So there.Now back to over-unity hallucinations.

A semi-trailer is one with only rear wheels, requiring support from the tractor at the front. "Semi" is much simpler.I haven't been in the UK since 2010: do the news reports of a traffic accident say "artic" or "articulated lorry". An American news report just says "semi".Some large American trucks tow a matching "trailer" behind the semi-trailer.

These circuits use combinations of diodes and capacitors to accumulate charge over multiple cycles, effectively "stacking" the voltage. So, a rectifier can produce a DC output exceeding the peak AC input - under the right topology.

content: Quote from: paul cotter on June 19, 2025, 05:17:26 pmPerhaps this is a matter of English language terminology. When I see the word rectifier, I tend to interpret it as a broader term referring to a rectification circuit - which may include configurations like voltage multipliers and any other kind of rectifier circuit. If the intention is to refer specifically to a single diode or a basic diode rectifier, I would expect more precise wording, such as "diode". Or am I mistaken in that interpretation and "rectifier" is also used to talk about "diode"?
