  1. CaptainPanic, I believe the major factor for the disappearance of steam engine derived power in industry and the home started in the early 1900's with the electric power generation industry, and the electric motor. The electrification of the U.S. was still ongoing in the 1960's. There were still steam engines being used in the remote and rural areas to power the electric generators. Saw mills, grist mills, manufacturing shops, were switching from steam power to electric motors as fast as they could afford to. The steam processes were still used and in place, but the motive power within the plants was switched to electric motors. Petroleum powered engines, together with electricity finally spelled doom for the steam engine in general. The improvements to the commercially available steam engines essentially ended in the auto industry in the 1930's, and as you say fuel economy was not a real concern. The highway system was still primitive and rural, and road trips were generally short compared to today. My point exactly, the information is scarce. If you can find something, I'd appreciate it. I believe the efficiency for engines can be greatly improved by both the application of steam power techniques, and the heat exchanger improvements. I'll go into more detail next post. Bob.
  2. CaptainPanic, Thank you for your careful considerations of my points. First I'll start with the steam cars of yesteryear. There were many many steam car manufacturers at the turn of last century. The whole industry was nearly dead by the 1930's, but two of them stood out, and lasted the longest because of their improvements. The Stanley, and the Dobel. Arguably the most advanced was the Dobel Car company. Its cars could be started up from frosty cold to drivable within 40 seconds with its flash boilers. The entire car had only 25 moving parts. Some of these cars had over 600,000 miles on them. The Model E, could go from 0 to 75 mph in 10 seconds, and 100 mph top speed. Check out http://www.damninteresting.com/the-last-great-steam-car If they don't think you could pick up chicks in one of these cars, they must be living on the moon. Another car to check out if you can find it is the Gvang steam car from Australia in the 1970's. I heard that it was bought up by Shell Oil Co. and promptly destroyed. What ever happened to Bill Lear's steam engine? My point here is a newly engineered and manufactured steam engine that could be dropped in as a replacement for a 350 chevy engine, and designed to be invisible to the operator is not only possible but doable. Problem being it would have to be aftermarket, as no OEM is going to touch it. No only that but other "factors" would present themselves to try to prevent your success. Because heat exchangers are a vital part of the engines system, their improved design would also contribute to the overall efficiency. Nearly all automotive and most industrial radiators, evaporators, and condensers, still use the same tube and fin designs with the serpentine fins that were designed in the 1900's. Most of the current thinking is, the thinner the fins and the more surface area, the faster the heat dissipation to the air. Also making more fins per inch along the tube will help. Several problems show up with this approach. First, The fin contact area on the tube has not been sufficiently increased. Second, Air is poorer than metal as a conductor of heat, so going thinner with the metal actually goes contrary to extracting heat from the tube to out along the fin. Third, While increasing the number of fins per inch along the tube does increase surface area, it also causes the air flow to be further restricted in its rate of flow across the exchanger, and is easier to clog up with debris. My heat exchanger design does greatly increase the surface contact area on the "tube" but at the same time its configuration also allows for a much easier cleaning because of much greater spacing to take advantage of increased turbulence, and a reduction of the back pressure in forcing air through. Boilers are still made the old fashion way, either fire tube, or water tube. Some small specialty boilers I've seen do greatly improve upon the water tube design and hold great promise, but by and large most everything else has not changed at all in how the water is brought to steam. Many companies are getting rid of their boiler systems because of the insurance, regulation problems and bureaucratic red tape and are going to steam generators instead. One liter of water will produce 1600 approx. liters of steam at atmosphere. With a steam engine of the Newcomen design, a single cylinder engine with a one liter displacement could have potentially 1600 power strokes, or 800 revolutions of a wheel. A one liter cylinder displacement is approx a 4 in. bore x 4in. stroke. ( I don't do metric conversion well) A 4 in bore has approx. 12 square inches area, times 15 psi atmosphere equals a 180 pound push on a crank with a 2 in throw, giving approx. 30 foot pounds of torque. This is roughly the equivalent of a 30 hp gas engine, and is done with an atmospheric steam engine that is not using pressure much above atmospheric pressure at sea level. Improvements are happening in different areas of steam like you say, but at a disappointing pace. Bob.
  3. DanHalen, Just run the air past your computer intake fan and the crt monitor screen. They should clean up the air pretty good by the way they collect all the dirt. Electrostatic air cleaners are used throughout industry and can do a fantastic job. They all have maintenance to be done. Someone has to clean them from time to time. Metal plates may be used no problem, just keep them statically charged to one of the polarities. Make arrangements to momentarily reverse the polarities, or mechanically rap the plates, and the dirt will fall off to the bottom. Some of the dirt will not fall off because it is mixed with cooking oils and other aerosols that have precipitated onto the plates, and this will have to be washed off during your maintenance. One cheap way from the old days of crt monitors, and still from cheap old tv's is to use the chassis with the flyback transformer circuit attached to the metal plates instead of the tube. Put the B+ on one plate, and the chassis ground to the other plate. B+ averaged around 25,000 volts, and could deliver a nasty zap, so be careful. Believe it or not but water droplets may be statically charged and attract particles, but you said cheap, and these aren't that, unless you want to construct one of Lord Kelvins thunderstorm chambers at home. It can be done, just Google Lord Kelvin's thunderstorm and check it out. Good luck, Bob.
  4. Swansont, ajb, If in all of these reactions all you get is more particles and their fragments, then what is being "converted". What does the E=... stand for in the math? More particles? Are gamma rays particles? What is binding energy, transition particles? Also in the fusion reactions, if pressures are high enough, then is it possible that nuclei bombardment and x-ray, gamma ray energies recombine these nuclei in a reverse of the decay sequence to form the larger elemental nuclei? Is that what is done when these powerful particle colliders momentarily produce new elements of extremely short half life with higher atomic numbers only seen in the lab? Lawrencium being the example. Just more thoughts, Bob
  5. Yomomma, You have some interesting information to be considered. Here are some sources that you may find helpful in your research. You may have to revise some of your views and your math after reading through it, but keep up your studies.

S. G. Valeev, S. V. Kurkina Ulyanovsk State Technical University, 32, Severny Venez st., 432027, Russià sgv@ulstu.ru It seems were are now in the beginning of another solar cycle with increasing magnetic sunspot activity and increasing radiance. See: http://en.wikipedia.org/wiki/Solar_cycle Impacts of the solar cycle There does seem to be correlation between magnetic sunspot cycles, and seismic activity on the earth, according to these references. Its apparently been happening like this for eons, so there is probably no need to be concerned about a doomsday scenario. Local human disasters caused by geologic event, though terrible, are nevertheless not indicative of worldwide disaster. I hope you’ll find these helpful. Bob.
  6. Ive been reading the most awesome book. It is The Urantia Book. It is also on line at http://www.urantia.org/en, as well as at Barnes and Noble bookstores. It has science stuff that will astonish you, check it out!
  7. These are questions that I don't have theories for or proofs, but just speculations based on "observations". Is there any evidence for or math for the "condensation" of energy back into matter? We know that in fission and fusion reactions, a portion of the yield is energy that does not have particles, "pure energy", but the remaining particles are matter. How are these elements formed in the first place? Where is the transition point? What would be the conditions necessary for this transition? Is it possible that the actions of fusion provide heavier and heavier and larger elemental nuclei with their corresponding electrons and they cool, with the remaining energy lost? Or does the energy as it disperses into the cold of deep space condense back into matter. We know that combinations of temperature and pressure give all manner of changes to matter, for instance water when heated under pressure to its critical temperature and beyond into the supercritical temperature behaves such that steam and the liquid phase become indistinguishable. Then is it also possible that this same condition can apply to matter at the much higher temperatures and pressures where particles of mass transition back and forth between mass and energy and are indistinguishable? Transitional particles of unknown properties would then exist under those conditions. Would the neutron stars have those conditions? Would our own sun have those conditions? Is it possible that the dark matter of space we've heard about is nothing more than the energy condensation that has clumped back together? Just some thoughts of a fevered brain. Bob
  8. Altair66 , Try Googling "Methernitha", and see if any of the information interests you. Although perpetual motion machines are unknown and theoretically impossible, there exists on the earth many possible sources of energy that have not been adequately explored to be developed as power sources. Most of our more easily derived power comes from the sun in different forms other than light. Some of this power may be within our reach of budget and understanding for its development. One cheating way to get some "perpetual power" is to construct a radio reception circuit that will tune into a local transmitting tower, and when Qd up, this signal is then rectified to DC to give a few watts of power continuously. Construction plans for these have been around for some time. I've successfully constructed electrostatic motors that would turn about 1500 rpm. My next step is to try to extract naturally occurring static sources and tie them into the motor circuit. The static is there, but so far I haven't succeeded. No, I'm not using the cat, mainly because she won't cooperate anyway.
  9. insane-alein, swansont, You are both right on the sensitivities of the different systems. If the period of the gravity waves frequency is very long, then the slower gravimeter system may be the way to go, but if they are extremely short, then they fall within the range of the laser systems extreme sensitivity. Isn't the suns gravity detectable as a "wave" with a period of 24 hours? Or the moon with a period of 28 days? What I feel is missing and I don't see in LIGO, is the vertical component that is in line with the earths gravity. With the earth gravity as the bias reference, incoming signals from gravity sources then add to or subtract from this vertical component. As they are now, only the horizontal arms of LIGO are used, and they are on the tangent of the earths gravity centerline. Perhaps a vertical shaft boring located at the apex of the other two arms, with suitable beam splitters and support equipment for the experiment could add that missing component. At any rate, gravity waves have yet to be detected by any of the current methods. See: http://www.wired.com/science/space/news/2007/10/gravitational_waves Can anyone explain the gravimeter signal variations (noise) that seems to come from directly overhead, and seems to correspond with the positions of celestial systems directly overhead? These signals can be verified, but separating noise from noise may be too tedious and unproductive. But, if they have direct correlation with directly overhead systems, then detecting the "waves" is a matter of fine tuning the system to eliminate the other noise. Granted it is amateur and with some far out speculation, but check it out anyway as this noise shows up on even the best instruments; http://www.rexresearch.com/hodorhys/smplgm/smplgm.htm Or; http://www.scientificamerican.com/article.cfm?id=detecting-extraterrestria&page=3 Bob.
  10. The concept of infinity in mathematics has of necessity to be constrained to a set in order for finite numbers to be applied in the formulas, and have any meaning in the resultant answers. Infinity is not null set, or undefined as is Zero, but a constraint on the endless progression, for the formula math to have a definable result. Numbers such as PI, or ones that are endless such as 12.666666.... to "infinity" are truncated for ease of use. After a determined amount, the remainder is of no value to the degree of accuracy required. For that matter all math that uses the concept of infinity is an approximation of the actual. Its is a matter of determining the level of accuracy required for the solution. Any manipulation of infinity by addition, subtraction, multiplication, or division, will give the same result unless it is constrained to a set, and thus limited to a resultant that may now be manipulated. In the physical world the infinities are distance and position from the observer. All matter and energy has been determined to be "countable" quanta with a space reference for both position and time. The infinity of distance is what is beyond the observable. The possible positions within the observable range, are supposedly infinite however with physical units the actual range of possible positions may not be infinite but constrained by their dimensions and their reactive behavior. Most of these actual numbers however are beyond our practical mathematics, and are just treated as infinity. For instance the number and frequency of collisions of molecules of a gas against a vessel wall that gives us a "pressure". Bob
  11. engineerjoe, If you will Google "amateur turbine", many sites will come up to perhaps get you started and fired up. Good luck, and when you are behind the protective barrier for startup, be sure to still wear your safety glasses! Bob.
  12. swansont, For a synopsis of gravimeters, refer to: http://geology.about.com/library/weekly/aa050999.htm A Project of Constant Improvement Fantastically sensitive gravity meters gather data now for science tomorrow Since gravity waves are still just a theory at this point, by what method did you determine the magnitude of sensitivity that is necessary for the gravity detectors? It may be possible that the detection of these waves will require a different approach for their discovery. Maybe just a different arrangement or combination of instrumentation. Constant improvements in equipment and methods for experimentation into everything conceivable concerning gravity waves will eventually turn up something, either proving or disproving the present theories. Some of this experimentation is within the reach of amateurs like us around the world. Bob.
  13. insane_alien, I guess I should have stipulated better the conditions of the experiment that I feel could be beneficial to the experiment. The layout on the ground may be 90 deg (possibly on the null plane) to the incoming signals. If one of these legs was pointing vertically at the source (eclipsing binaries), then the detecting elements would be in alignment with the incoming signals. Possibly by using the LIGO laser systems aboard geosynchronous orbitals. By using laser interferometry to sense the action of the gravimeter, the detection systems capabilities of both would be enhanced by their combined sensitivities, thereby providing the necessary levels of sensitivity for the experiment. Further thoughts, Bob.
  14. insane_alien, I've perused through the LIGO, and find it very interesting and may be usefull when tied in with other possible experimental approaches. I don't believe LIGO alone is going to it. For instance, We now have gravimeters that are extremely sensitive to gravitational changes. If these are combined with the laser interferometry and arranged in such a way and positioned to precisely aim (source to the gravity center of the earth) at rotating eclipsing binaries, for instance, and compare the signal if present, to the light signal to confirm the alignment, then we just might have a system that detects observable gravity information from that source. These binary rotating stars are essentially modulating gravity (opinion), but the detection of that modulation is the test that hasn't been passed yet. Bob.
  15. insane_alien, The propagation speed of gravity is still an ongoing debate. See http://iopscience.iop.org/0004-637X/590/2/683/fulltext Bob. Merged post follows: Consecutive posts mergedinsane_alien, If gravity waves exist, wouldn't they be part of the electro-magnetic spectrum? And if not, then by what means can they be detected? Bob.
