| Dear Tom, tadchem wrote: LOL, I knew you would say that Tom. Actually I had typed "and say the atoms are traveling at a few cm per second." I removed that before posting because I thought it was an insult to your intelligence. Look Tom, for the sake of proving a point, let's say the atoms are traveling slow enough for the super cray to handle the data input. Wow! :-) Side A are of this Tom, you give it momentum while it's moving but then you take away that momentum when it stops. So the nano device moves, then stops and waits to be hit, then moves away, then stops-- slow moving atoms, OK. This is fun. I feel like I'm riding the Matterhorn. ;-) contact atoms the allowing know how Thank you. You're not Japanese are you, btw? my current electromagnetic under predictions, error is overlooking a For example? The simulations were tested on a wide range of tests. For example, one of the latest test was taking a toroid (magnetic material) and wrapping wire around the toroid. Sounds common so far. Then I added a second winding. This winding consisted of very long straight wires. So you're looking sideways at the toroid. You have wire that's going up through the toroid, but in this case the wire continues to travel up for over a foot. That is, the wire extends a foot below and above the toroid. Although the wire does not extend sideways away from the toroid. So you have very long vertical wires. What this does is it tests the electrodynamics and magnetic equations at such angles. The simulation results were perfect. lost the of it: solid. It magnetic ordering are conditions the the magnetic of the small magnetic electric adiabatic I never said nor insinuated that the Magnetocaloric effect is evolved in the two wire ring test. That should go without saying since that test has no magnetic materials. I am puzzled why you would say so since I clearly stated that there were no magnetic materials in that test. One of the goals of that test was to demonstrate that the program would not introduce any source of free energy without the magnetic materials. magnetic to current. test breaking different.] I'm not sure you understand the method. You have a loop of wire. The program segments the wire into thousands of pieces. This is the only method to equate the net results of a complex system. You're not breaking any wires. You're simply *analyzing* each segment of the wire. Yes, there are equations for a simple round circle of current as far as calculating the magnetic fields. Also someone may have constructed the math for the electromagnetic fields of a circle of current at di/dt, but I haven't seen any. That's beside the point since I intended on plugging in complex wire designs beyond a simple circle. Segmenting is the way to go. Takes a lot of work but it's worth it and yields very accurate results. Simulations were based on experiments. No. That would take probably 2 minutes to add to the program. My initial goal is spot the source of free energy. I already know such losses exist. Same answer. The only thermal loss would be from the magnetic material becoming colder. I would go out of my way to actually blow air or liquid across the core to keep it as close to room temperature. As far as heat from current, that's would be part of wire resistance. Yes. The initial simulations did not, but the last version used Ising simulation code to compute the hysteresis losses. As mentioned, the last version still possessed a flaw in that the code would theoretically break down at magnetic saturation levels. This did not affect the free energy design that had the moving parts, as displayed in the two animations. That particular design did not require saturations. Although, all solid state design I have so far require extremely high saturations. That is why I'm writing the grand final version, which will eliminate the saturation limit. This is going into extreme details of the project that would take me months to catch you up to speed. So I apologize if I did not answer your question to your satisfaction. I am still not certain that I can discover a solid-state design. If not, then I will build the machine described in the research paper. As far as radiation resistance, which is caused by the electromagnetic far field of an oscillating signal, no. That's simply a limit on frequency relative to core size. In my designs the radiation resistance will be a fraction. Yes. conductors? No. You don't see to understand. The simulations were for verification purposes. You do not need to introduce elasticity, nor do I need to introduce air friction and such. When you perform tests to verify a key area, you do NOT want to introduce other forces. That's one great aspect of computers; i.e., you can keep your tests pure and blemish free. If I did introduce such forces, and I could, then I simply have to separate that energy because I need to focus on the kinetic energy relative to electrodynamics energy. The program keeps a tally on all the energies. Again, the goal is to prove and hone in on the potentially free source of free energy. We can concentrate on overcoming such losses when we prove the effect exists. the The power source was a current source. The power is computed by the induced voltages times current. If the induced voltage is with the current then power is gained. If the induced voltage is against the current then power is lost. Kind regards, Paul |

Oxygen moves at 1.40 km/sec at 298 °K, so to slow it down to 100 cm/sec we would have to cool it to 298*(100/140000)^2 = 0.00015 Kelvins. You plan to extract energy from that? At what cost of energy? let us figure this out: What is the mass M of your nano device? How much t time are you taking to move it? How far x are you moving it? You need to move it a distance x/2 in a time t/2 at an acceleration a from rest to a velocity v. From elementary dynamics we calculate that the acceleration a = 4*x/t^2 The force applied to the nano devide is F = M*a = M*4*x/t^2. The energy required to perform this feat is E = f*(x/2) = 2*M*x^2/t^2. Repeat this for the deceleration phase, and you have *expended* 4*M*x^2/t^2 just to get your nano device *into position* to intercept a gas molecule moving at a 'few cm per second.' How much more massive is your nano device than a single gas molecule? Do your simulations consider the mass of the nano device and the energy required to move it around? More like riding a shuttle train to catch up with a table tennis ball. B-( I've studied a little Japanese, I watch a lot of anime, I read a little manga (translated), and I'm trying my hand at calligraphy (I painted "watashi no kuruma desu" in Hiragana over the driver's door to my car - a little Shinto 'charm' of protection against theft). Your question suggests you have not heard of James Clerk Maxwell's demon: [Only registered users see links. ] [Only registered users see links. ] [Only registered users see links. ] [Only registered users see links. ] Are you asking me to critique your numerical method without ever seeing the code? I am not that foolish. I will point out that as recently as 20 years ago people who were very enthusiastic about numerical modeling and supercomputers applied their theories to climate modelling and concluded that the earth was getting warmer because the atmospheric carbon dioxide levels were increasing. All the models agreed that this was happening, although they were not in agreement about the magnitude of the effect. Then someone tried climate modelling in a *reverse time* protocol, and found that as they extrapolated back into the past the earth *also* got warmer. even when they pre-programmed the known lower values of carbon dioxide, the calculated values of the mean climate temperature seemed to gfet warmer the further the extrapolations went away from the present. A few of us who were schooled in Numerical Analysis and computer algorithms recognized the problem immediately. In fact, some (myself included) had recognized the probable risk of this error even before the 'reversed time' calculations were run. The problem arose because of what numerical analysts call 'accumulated roundoff error.' When a calculation produces a result that is beyond the number of digits supported by the hardware, the result must be rounded. According to approved ASTM protocols, residues less than 0.5 are rounded down, residues greater than 0.5 are rounded up, and residues equal to 0.5 are rounded to an even digit - i.e. 1.5 and 2.5 are both rounded to 2. However, hardware rounding in standard computer designs used to always round *UP*. This means the self-correcting effect of the ASTM protocol for rounding was absent, and sometimes results that should have been rounded down were rounded up. When you are performing a model calculation that calculates *billions* of temperatures and only 1 in 20 to 40 is rounded up when it should be rounded down, the "global average" (pun intended) becomes artificially elevated. The claims made in the 1980's that the sea level would rise by 300 meters in 50 years are patently absurd - now. They *seemed* reliable then to people who were not aware of the problem of accumulaed roundoff error. But what would they know - they weren't numerical analysts, they were climatologists. It is a common problem that trained minds misinterpret something and are led down a primrose path because the anomalous results do not trigger them to question their assumptions. |

So your only defense now is that such a nano test seems impractical. Trust me, lol, it has nothing to do with my research paper. I entered into the thermodynamics discussion with you because you refused to believe that my premise could be possible due to the laws of thermodynamics at the atomic level. So, will you so kindly admit that this tiny cube and nano assertion is theoretically possible? Momentum consumes energy when an object accelerates and momentum gives energy when the object decelerates. :-) If you accelerate an object and then decelerate it back to the original speed then there's no net loss due to momentum. I am somewhat amused how you get so easily caught up in noise such as friction, losses, etc. when this has nothing to do with losses and such but rather it's an assertion to prove or disprove a theory. In fact, when you perform experiments to prove or disprove theories, you want to eliminate as much noise as possible. Do Wow, LOL! This has nothing to do with my research paper. I am not working with nano devices. You've made numerous comments in recent posts that demonstrate you did not even read a fraction of my wiki project. Sincerely, Paul |
