BTW, since yourself and others of your brown-nosed kind refuse to place your real name along with whatever faith-based group makes you into happy campers, the pretend atheism analogy so that you can fence jump all you want is pretty much all that's left for the rest of us village idiots to work with, in trying to figure out whatever's actually in charge of your mindset and your private parts. Why don't you stick with at least two or three of those faith-based groups that don't continually **** you off. Most honest folks have that one nailed down to just one or possibly two faith-based groups they'll directly associate and/or interact with, because all the others are just plain and simple dead-wrong about something that doesn't sit well enough within their private mindset of whatever their idea of faith is all about. . -BradGuth BradGuthand the God Hole Of 3.56e80 m3 and supposedly only 1e80 atoms is suggesting that on average we have far less than one atom per cubic meter. I don't exactly buy into that low number because, so many new forms of red- dwarf, brown-dwarf and possibly even black-dwarf stars as black holes seem to be uncovered all the time as our technology improves and intellectual scope takes such into account. The complex soup of space is anything but a vacuum. The physical vacuum seems entirely full of energy that's fluid and interactive, as seen in the UV and night-vision or starlight video taken by various shuttle missions, as well as by those of ISS using unfiltered camera optics and having sufficient dynamic range (terrific FWC along with minimal dark noise is what yields DR), and especially if shooting such video at 1/16th second scan or exposure per frame is going to record far more spectrum and of those weak photons, allowing the human eye to see into this realm of space thought as being a vacuum. Lets say for the argument/rant sake that we have 1e100 all-inclusive stars within our ever expanding universe, including those newish of UV + and oldies of IR- status. If on average there were only one photon/sec arriving per star into a given ISM m3, as such this might rather easily suggest a population of 1e100 photons/atom if there were but only one ISM atom/m3. As best we think we know about the ISM(inter stellar medium), for the most part there's more than likely at least 100+ atoms/m3, and as I might otherwise surmise there's also going to be well over 100e100 photons/sec/m3, if not several thousand e100s of those all-inclusive photons/sec/m3 to work with, because that's the complex interactive soup or elastic binder of what makes our universe tick. On yet another universe soup/binder related topic, is to ponder as to how big was the original BH(black hole) or GH(God hole) of our universe: If our sun is of the average at 2e30 kg, and if given 1e100 stars = 2e130 kg 2e130 kg compacted down to a thousand fold greater density than a white dwarf isn't so terribly large, especially if the ultimate core of that BH/GH was offering a good million fold more density than a white dwarf, as such would make our initial BH/GH imaginable and thus capable of being supercomputer simulated within a very 3D interactive format. There's no argument that such photons take the all-inclusive X-prize for being the greater worth of what our universe is all about. Unfortunately, our human vision isn't capable of directly interpreting such because, it seems our visual perception isn't worth 0.0001% of detecting what's out there in the supposed vacuum of space, and far too many intellectual humans simply do not accept whatever good physics and science detects because it's not of what their terrestrial limited God permits. Obvious errors corrected on behalf of my last paragraph, but then Saul Levy is so all-knowing that nothing really matters, does it. - Sirius-B as a nearly earth-sized white dwarf offers an average density of 1e9 kg/m3, so a thousand fold worth of 1e12 kg/m3 could become our average God Hole density, with a nucleus core of perhaps 1e18 kg/m3 if not greater, of which might suggest a fairly small GH that'll represent the initial universe. Of course this means there's far more to our complex universe than meets the naked human eye, or even by way of the best instruments our eyes can interpret. - In addition to Venus being so gosh darn nearby and very much alive and kicking, our moon having been global warming us ever since the last ice-age Earth will ever see, as well as our solar system headed back towards Sirius, I'm still working on my God Hole(GH) theory, not that your conventional BH, DM and DE don't exist as is. .. - Brad Guth |

At least Robert Clark isn't against our use of ions for thrust, and of notions for storing enough of such ions for creating a fairly substantial amount of volume sustained thrust if given the necessary energy for accelerating such ions is part of the package deal. *Of course, I've had to correct those usual robo-moderated words as having been run together, so that a normal key word search would even turn up this "Stored ionized gas for ion drives" contribution of his, stating that such ion exhaust/exit shouldn't have any difficulties in obtaining 10,000 km/s. *Whereas I'm thinking the 16.7e3 km/s of the natural 5.6 MeV radium alpha/ion particle itself is perhaps not half of what a electrostatic boosted and magnetic focused Rn222 ion could muster, therefore its potential exit velocity of 34,000 km/s (that's better than 0.1'c') seems entirely doable, and of the much greater mass of the Rn222 ion should by rights benefit the thrust potential without ignoring any of those laws of physics. http://groups.google.com/group/sci.s...frm/thread/109... From: Robert Clark Date: Sep 28 2007, 4:53 pm Subject: *Stored ionized gas for ion drives. To:sci.space.policy, sci.astro, sci.physics, sci.physics.relativity, sci.physics.fusion On Sep 20, 4:47 pm, Robert Clark wrote: *This page gives a formula for the exhaust speed of an ion engine in terms of the charge on the ions and the voltage driving the ion flow: Ionthruster. http://en.wikipedia.org/wiki/Ion_thruster#Energy_usage *The exhaust speed increases with the charge on the ions and decreases with their mass. You would think then that a light gas like hydrogen would be ideal since heavier gases even when fully ionized would still contain approximately equal numbers of neutrons as protons which would not contribute to the charge but would approximately double the mass. *Yet it is the heavier gases like cesium and more recently xenon that are used. The explanation is that of the energy it takes to ionize the gas used as fuel. The figure on this page shows the energy to ionize a light gas such as hydrogen is relatively high compared to the heavier gases: Ionization Energies. http://hyperphysics.phy-astr.gsu.edu...al/ionize.html *The figure gives the energy per mole which is high in itself. It is even worse when you consider this on a per mass basis since the mass amount of hydrogen would be so small compared to the amount of energy needed to ionize it. *So could we instead store the hydrogen or some other light gas already in ionized form so we would not have to supply power to ionize the gas, only to accelerate it? *If you used ionized hydrogen, so you would be accelerating protons, then using 6 x 10^18 protons to make one 1 Coulomb, and a mass of 1.6 x 10^-27 kg for a proton, and V representing the voltage in volts, the speed on the ions (protons) would be about (10^4)sqrt(2*V) in meters/ second. *If we made the voltage be 5,000 V we would get 1,000,000 m/s speed much higher than any currentiondrive. Also, there are power supplies that convert low voltage high amperage power into high voltage, low amperage power, even up to 500,000 V. Then we could get 10,000,000 m/s = 10,000 km/s exhaust speed. *The question is could we get light weight means of storing large amounts of ionized gas? Note that is this for space based propulsion not launch from Earth. You would have a possibly large energy generating station that remained in low Earth orbit to supply the power to ionize the gas once the spacecraft was placed in orbit. The power generator would be left behind in orbit. Then the volume of the gas container could be large to keep the density of the gas low. This would allow very thin container walls. Note the low density would also allow the electrostatic repulsion of the positively charged ions to be more easily constrained. *A possible problem though is the charged ions contacting the walls could lead to a loss of ionization. You might be able to use a low level magnetic field to prevent the ions contacting the walls. Low density of the gas would insure the strength of the magnetic field required would be low. It might even be accomplished by thin permanent magnets so you would not need to use extra power. *Some questions: what would be the electrostatic pressure produced by a low density highly ionized gas? What strength magnetic field would you need to contain it? *Note that with an exhaust speed of say 10,000 km/s, by the rocket equation we could get the rocket itself up to relativistic speeds with acceptable mass ratios. *Then this would provide a means of testing relativistic effects on *macroscopic bodies. * *Bob Clark There is a lot of research on containing charged particles of only one charge, that is, all positive or all negative, because of fusion research. These are called "non-neutral" plasmas. There is a limit on the number of charged particles you can contain in a magnetic trap based on the strength of the magnetic field called the "Brillouin limit." However, some researchers have argued it is possible to exceed This limit: Confinement Of PureIonPlasma In A Cylindrical Current Sheet. http://www.pppl.gov/pub_report//2000/PPPL-3403.pdf *Bob Clark Perhaps others might care to ponder and subsequently offer their best swag(scientific wild ass guess) as to our getting the most out of ion thrust, not that Ra226-Rn222 need be the one and only alternative. However, with that nearby and gamma saturated moon of ours might actually suggest there's a good amount of Radium to behold, and at a $1M/gram seems entirely worth going after, more so than whatever 3He. (why the hell not accomplish extracting both?) . - Brad Guth On Feb 8, 7:59 am, BradGuth wrote: A good source of thruster ions that'll keep coming is from the likes of Radium that creates the Radon (Rn222) gas. *Radium is somewhat rare, but it is not as an element uncommon. *However, of what's most uncommon is any public disclosures or education about Radium. Apparently the element of Radium is officially taboo/nondisclosure rated, especially as far as to who has what and at whatever current market value. *Essentially, this need-to-know market price of Radium is at least a thousand fold more government cartel hocus-pocus price fixed than anything of fossil fuels or even of yellowcake, though the formal extraction process of obtaining roughly 100 milligrams per yellowcake tonne is essentially a robotic task from start to finish. For the most part, Radium is actually another one of those discarded elements within spent nuclear fuel, as well as found at less concentrations within most mineral tailings or otherwise given as a slight part of most all fossil fuels, that which the fossil energy industry as a whole do not bother to extract or otherwise divert this element from the subsequent CO2/Nox laced combustion soot, much of which simply goes either directly into our atmosphere or if in full clean-air compliance merely gets relocated into various landfills that'll eventually end up eroding and/or blending back into the general environment. *Of course none of the valuable 3He has been collected either, so what the hell. Naturally-occurring radioactive materials (NORM)http://www.eoearth.org/article/Natur...oactive_materi...) A *great amount of Radium and subsequently Radon comes into our surface environment though fossil fuel extractions and subsequent usage, and much of whatever's initially kept from being atmospherically dispersed as CO2 and NOx contaminated soot that's laced with a slight trace of Radium is simply buried in relatively shallow graves or in some cases utilized as fill for open pit mining site recovery. *In other words, most all of the mined elements of radioactive fuel that used to be safely sequestered far enough underground, essentially away from our frail DNA and surface environment, has been systematically and artificially reintroduced into our life sustaining environment, along with as little public education as possible so that folks are simply snookered into being unaware of these surrounding concentrations and dosage levels that we all have to cope within. Radon gas; "reportedly causes 21,000 lung cancer deaths per year in the United States alone."http://en.wikipedia.org/wiki/Radon If that be the case, then by any global/world standard could be looking at as many as 400,000 Radon gas related deaths per year, if not an all-inclusive 500,000 in radiation contamination related deaths per year (keeping in mind that fewer than 500 pandemic deaths per year would become a world health alert with multiple quarantines imposed). Therefore, rounding up as much of the spare/surplus Radium as possible seems like a perfectly good sort of task worth doing, so that it can be either put safely away or at least properly utilized in a manner that doesn't further traumatize our frail DNA and badly failing environment any more than absolutely necessary. *Like U238 yellowcake of 80% grade, whereas perhaps the 100 mg/tonne of 90~97% extracted grade of this refined Radium ore doesn't amount to all that much by volume, but clearly what there is of it has become extremely valuable as well as humanly lethal if continually ignored as is, not to mention what adverse affects are imposed upon all other plant, animal and microbe forms of life that surrounds and benefits us, and in one way or another gets involved and/or consumed by us humans.

You can always post on top portion of the given reply, as that way
your text isn't hidden off-page. And you don't always have to include the entire body of other text if you'd like keeping the given reply more readable by those dropping in for a quick look-see. Ion propulsion or ion thrusters are becoming the ultimate alternative for the future of faster and more extended space travels, although the usual topic taboo or nondisclosure nature of this Usenet and of most other web forums is truly impressive, as in don't ask and don't tell, or else they'll kick our butts. Of second to ion propulsion is gravity, and big nasty star/solar systems do tend to pull upon whatever is on their side of the interstellar L1, especially if such an item as a spacecraft or robotic probe were getting ion thrusted towards that given star at even as little as 0.000001 Gee. BTW, they supposedly don't much care for a direct sales pitch of items within Usenet, but compared to everything else they allow, what the hell.

Sirius B orbits Sirius A every 54 years. There are many other larger star clusters around us; some containing 2500 stars. To make a very long story short after our sun was born in Orion with about 40 other stars. The planets formed from extra material and we drifted out away from Orion for three billion years. Earth had a 1450 pound per square inch atmosphere and 1/3 of it was CO2. Earth had an Ice Age that lasted over a billion years and finally we drifted between Procyon and Sirius into a mutural gravity alignment point. Sirius B with 1.5 solar masses that orbits Sirius A every 54 years came around and put our Sun into orbit around Sirius while our sister stars kept going and are in a much larger orbit. The aditional light and heat from these very old stars took Earth out of it's billion-year-long ice age and the intense light from Sirius B which puts out from 100 to 1000 times more UV than our sun started plants growning on the surface of the oceans. It took the intense light from a neutron or white dwarf to penetrate earth's 1450 pound per square inch atmosphere and start laying down coal, oil and limesone with plant growth. 650-million years of this took earth's atmospher down to 14.5 pound per square inch giving us free oxygen, coal, oil and limestone. You can't drive a car without a neutron star! You can read the entire book in a couple months by ordering it from Trafford of Victoria British Columbia, Amazon.com Boarders, Bokers Etc., Etc. You can read a dsylexic version of it right now by going to my web sitewww.alaskapublishing.com. It can be downloaded for $4.00. I got my directions backward in regards to which way we are heading for Sirius. The mainstream information I have to work with is not that good. The book itself will be awsome with over twenty wonderful, full-page, full-color images and graphs. WWW.ALASKAPUBLISHING.COM BEST WISHES, HANK |

The Ion Interstellar Spaceship, from Hell to Sirius

However, upon launch and of once reaching the cool upper most atmosphere is where the potential of ion thrusting could start to contribute w/o Radon saturating Earth in the process, and obviously from whatever LEO point onward is where the real potential of ion thrust becomes impressive, especially since this method of electro-rocket thrust can be sustained for as long as the given cache of ions and electrical energy holds out.

Radon just so happens to make for a very good cache of substantially massive ions that are already quite active/reactive and supposedly going places as is, at roughly 1.63e7 m/sec. Liquid Radon or LRn222 represents a nifty fluid cache of a easily stored concentration of Radon gas (though because of its short half-life it's still very much one of those use it or lose it substances, with possibly an extended life within a near solid 0 K storage), of which I believe this cache of Rn222 can be electrically induced or excited into exiting this ion thruster at a velocity as great as 0.1'c' (perhaps an exit velocity of 0.5'c' is technically doable if we're talking about a radon pumped laser cannon). Similar to: http://en.wikipedia.org/wiki/Ion_eng...ColettiMPD.pdf Our lord all-knowing (aka World FactBook) Mook says; "Check it out" Here is how much thrust a rocket engine produces; F = mdot * Ve where mdot = mass flow rate, as kg/sec Ve = exhaust speed m/sec F = force (newtons) kg m/sec/sec Here is how much power a rocket engine's jet produces P = 1/2 * mdot * Ve^2 That is, the rate at which energy must be added to the exhaust jet is the kinetic energy of the parts. - - - - Of course this is not about any Mook passive alpha particle directing application, instead taking efficiency of the overall electrical and ion tossing system into account (such as thermal energy losses) adds to this existing amount of ion worth via applied electrical and magnetic energy that'll focus and accelerate those ions. So, it is not nearly as simple to express as one as Mook might suggest. However, at the notion of our getting rid of this initial tonne worth of our liquid cache of LRn222, at the ion mass flow rate of 1 kg/s, whereas the kinetic power or energy worth of thrust supposedly becomes: If the 1 kg/s flow of Rn ions and the exit Ve were made as great as 10%'c' = 3e7 m/s P = .5 * 9e14 = 4.5e14 kgf At utilizing this ion exit velocity of 0.1'c' (3e7 m/s) A metric tonne of LRn that'll essentially become just plain old Rn gas of pure Rn222 ions, at using up one kg/s = 1000 seconds worth of creating 4.5e14 kgf, of which this substance would push a 4.5e12 kg (4.5 gigatonne) spacecraft at 100 gee in relationship to the gravity at the surface of Earth. At the more realistic ion exit velocity of 1% light speed is 0.01'c' (3e6 m/s) A metric tonne of LRn that'll essentially become just plain old Rn gas of pure Rn222 ions, at using one kg/s = 1000 seconds worth of 4.5e12 kgf, of which would push a 4.5e10 kg (45 megatonne) spacecraft at 100 gee in relationship to gravity at the surface of Earth. Of course the 45 megatonne spacecraft isn't hardly any more likely than human DNA or whatever spacecraft structurally surviving 100 gee. So, to start off with we'd likely have ourselves a whole lot smaller than 45 megatonne spacecraft, such as perhaps only as great as 4.5 megatonnes that'll exit away from Earth at perhaps as great as 10 gee, then once 10r (63,730 km and just 1% Earth gravity) is reached, whereas this is when the ion exit velocity could be safely punched up from 0.001'c' to 0.01'c', and eventually the maximum of 0.1'c' could be applied to as little as using a gram of Rn222 per second, because at 0.1'c' or better exit velocity is where you really do not require all that much mass flow per second. 0.1% light speed is 0.001'c' = 3e5 m/s 1 kg/sec at 3e5 m/s = .5 * 9e10 = 4.5e10 kgf 4.5e10 kgf would push a 4.5e6 tonne spacecraft along at 10 gee Using a gram/sec: 4.5e7 kgf would push a 4.5e6 tonne spacecraft along at 0.1 gee I believe that 1000 seconds of 10 gee acceleration is worth 78.4 km/s, though of course we'd be past the 10r of Earth within the first 600 seconds, and thereby able to ion whiz past that 78.4 km/s mark like it was standing still. This next part is often where my math takes yet another nose dive, but since I do not have the fly-by-rocket software and none others that claim as always being all-knowing are seldom willing to share, is why I'll just have to make do, especially since even the warm and fuzzy likes of Mook always takes the lowest road possible in order diminish and/or disqualify whatever isn't of his idea to start off with, excluding just enough of the good stuff in order to foil any further thought process. The required energy for a given thousand seconds worth of accelerating those Rn222 ions up to 3e5 m/s isn't exactly insignificant, demanding perhaps at least 245.2 GW.h (8.826 e14 J) for accommodating all 16.7 minutes worth of ion thrust. However, due to the overall efficiency of this energy transfer into accelerating those Rn ions is why it'll more than likely demand somewhat greater energy for accomplishing this task of tossing out the entire tonne worth those Rn222 alpha ions at the rate of one kg/s, even if that's initially accomplished at this minimal 0.001"c". However, since the existing Rn alpha particle velocity is already self motivated at 1.6e7 m/s(.054'c'), perhaps along with given another 5.6 MeV boost is where the required energy can be limited as to whatever's necessary for accomplishing a good exit focus or creating that laser cannon like beam, in which case the required ion thruster energy could become relatively minimal for accomplishing an impressive exit ion velocity of 3.26e7 m/s. At times this spacecraft is going to require a hole lot more electrical energy than any cache of Radium to Radon reactor could manage at 32 kw/Ra tonne, or even 320 kw/breeder Ra tonne. However, at a gross spacecraft mass of 4.5e6 tonnes, there's no problem with incorporating an h2o2/aluminum fuel cell of 100 GW.h capacity, or accommodating whatever Lithium nanotube ion battery storage, nuclear reactors or fusion alternatives. Once trekking off into interstellar space, and especially upon getting this craft past our nearest interstellar L1, and of the other gravity pulling us towards the likes of the relatively massive Sirius star/ solar system that we're already in blueshift as headed towards Sirius, as this is when as little as a mdot microgram/sec of Rn222 at the exit velocity of 0.2'c' would be more than sufficient ion thrust for continually accelerating this 4.5e6 tonne spacecraft towards the gravity pull of Sirius. For a one microgram/sec of Rn222 mdot at 0.2'c' example: P = .5e-9 * 3.6e15 = 1.5e6 kgf (1,500 tonnes/s of thrust, or in this case 0.000333 gee) The next problem gets down to the business of continually building up another cache of LRn from the Ra-Rn breeder reactor while on the fly, on behalf of that pesky matter of our having to ion retrothrust long before overshooting the intended target. At 4.5e9 kg, stopping this sucker that's by now going like a bat out of hell (possibly having reached 0.1'c') is going to take some doings. Of course, there would be generations of new and improved minds onboard in order to figure most of this out before arriving into the Sirius star/solar system, not to mention whatever could have been transmitted from Earth over the past century. BTW, at this point of topic argument sake, this mission to Sirius is a one way ticket to ride, with absolutely no travel package guaranties or ticket refunds allowed, because we may not be able to sufficiently retrothrust in order to save any of those brave souls, and a purely gravity-well trajectory turn-around or that of sufficiently aerobraking is at best iffy, although a substantial solar wind parachute as brake might eventually work. Also, recall the sheer size of these required ion thrust nacelles, as being somewhat Star Trek Enterprise like, and for all we know in need of those lithium crystals or perhaps lithium nanotubes as part of their function (after all, any good science fiction uses the regular laws of physics and the best available science, and for all we know lithium could still be part of it). . - Brad Guth How the heck did ions become so taboo/nondisclosure rated? .. - Brad Guth |

The Ion Interstellar Spaceship, from Hell to Sirius
If upon average there were merely 150e6 atoms of Rn222 per m3 of
air, seems to suggest that a good amount of Ra226 can't be all that too far away. In places the intensity or occurrence of Ra226 that's creating such atoms of Ra222 is of course much greater than 150e6/m3, primarily because radon is a heavy gas is why it hugs the surface at much greater occurrence or population by a good hundred fold = 1.5e10/ m3, meaning that in many places the background of Radium(Ra226) is hard at work in the natural decay process, as is naturally making enough Rn222 available for creating and sustaining a good supply of commercial liquid radon (LRn222) for ion thrust applications a very doable thing. http://en.wikipedia.org/wiki/Radon "At standard temperature and pressure, radon forms a monoatomic gas with a density of 9.73 kg/m3, about 8 times the surface density of the Earth's atmosphere, 1.217 kg/m3, and is one of the heaviest gases at room temperature and the heaviest of the noble gases (excluding ununoctium). At standard temperature and pressure radon is a colorless gas, but when it is cooled below its freezing point (202 K ; -71 °C ; -96 °F) it has a brilliant phosphorescence which turns yellow as the temperature is lowered, and becomes orange-red at the temperatures air liquefies (below 93 K ; -180 °C). Upon condensation, radon also glows because of the intense radiation it produces." "At standard temperature and pressure, radon forms a monoatomic gas with a density of 9.73 kg/m3" "Radon collects over samples of radium 226 at the rate of around 0.001 cm3/day per g of radium." Therefore, per kg of Ra226 you'll get 1 cm3/day, and per tonne of Ra226 you'll obtain a liter of Rn222 that's worth 9.73 mg, of which doesn't sound like all that much until it's made to exit the ion thruster a 0.5 c, or roughly 150,000 km/s = 219 TN.m or TJ (teraJoules), or if you like 23.34e12 kgf.m of reactive force. Note that radon gas has been officially identified as the primary cause of 21,000 lung cancer deaths per year in America alone, and we're not even as nearly at risk as other more radium/radon saturated areas around the planet, so we can safely extrapolate our 21,000 deaths caused by radon to a global annual death impact rate of 462,000 per year. In epidemic or pandemic terms, even 462 global deaths from a given toxin or nasty microbe would be extremely alarming, but oddly 462,000 deaths/year from the affects via radium/ radon is not given a mainstream hoot worth of consideration. Of course fossil fuel drilling extractions, of mining solids and of various transporting, processing and the final consumption that unavoidably deposits such raw elements as radium and thus places a continuous supply of radon into our surface environment via the mostly invisible soot of combustion that includes CO2 and NOx that's laced with radium/radon isn't exactly helping, especially since little if any efforts are made to extract any of the radium prior to combustion or even from the vest bulk of exhaust which covers and unavoidably pollutes our entire global environment. So, it's all rather odd that the all-knowing folks like our William Mook (aka willie.moo) seems as though entirely unconcerned as to these extensively artificially introduced toxins of radium/radon, that represents such a well-known cancer causing element that's existing in nature as well as getting so freely dumped into our frail environment, instead of being easily identified, gathered up and properly utilized in a perfectly safe and highly energy efficient application on behalf of ion thrusters. Of course the same argument of our policy of having ignored the "waste-not want-not" aspects of 3He that's continually going to waste, all because it too hasn't been extracted from surface minerals or from fossil fuels. Is it just myself that cares about the future of humanity and of most all other life on Earth via salvaging our frail environment that's getting industrially traumatized before our mostly "no child left behind" dumbfounded nation of village idiots, while at the same time doing perfectly good things with radium/radon? . - Brad Guth BradGuth wrote: On Feb 7, 10:40 am, BradGuth wrote: What if instead of our going with whatever's small, extremely cheap, fast and rad-hard robotic, what if going with larger is nearly always better?

So, to start off with we'd likely have ourselves a whole lot smaller than 45 megatonne spacecraft, such as perhaps only as great as 4.5 megatonnes that'll exit away from Earth at perhaps as great as 10 gee, then once 10r (63,730 km and just 1% Earth gravity) is reached, whereas this is when the ion exit velocity could be safely punched up from 0.001'c' to 0.01'c', and eventually the maximum of 0.1'c' could be applied to as little as using a gram of Rn222 per second, because at 0.1'c' or better exit velocity is where you really do not require all that much mass flow per second. 0.1% light speed is 0.001'c' = 3e5 m/s 1 kg/sec at 3e5 m/s = .5 * 9e10 = 4.5e10 kgf 4.5e10 kgf would push a 4.5e6 tonne spacecraft along at 10 gee Using a gram/sec: 4.5e7 kgf would push a 4.5e6 tonne spacecraft along at 0.1 gee I believe that 1000 seconds of 10 gee acceleration is worth 78.4 km/s, though of course we'd be past the 10r of Earth within the first 600 seconds, and thereby able to ion whiz past that 78.4 km/s mark like it was standing still. This next part is often where my math takes yet another nose dive, but since I do not have the fly-by-rocket software and none others that claim as always being all-knowing are seldom willing to share, is why I'll just have to make do, especially since even the warm and fuzzy likes of Mook always takes the lowest road possible in order diminish and/or disqualify whatever isn't of his idea to start off with, excluding just enough of the good stuff in order to foil any further thought process. The required energy for a given thousand seconds worth of accelerating those Rn222 ions up to 3e5 m/s isn't exactly insignificant, demanding perhaps at least 245.2 GW.h (8.826 e14 J) for accommodating all 16.7 minutes worth of ion thrust. However, due to the overall efficiency of this energy transfer into accelerating those Rn ions is why it'll more than likely demand somewhat greater energy for accomplishing this task of tossing out the entire tonne worth those Rn222 alpha ions at the rate of one kg/s, even if that's initially accomplished at this minimal 0.001"c". However, since the existing Rn alpha particle velocity is already self motivated at 1.6e7 m/s(.054'c'), perhaps along with given another 5.6 MeV boost is where the required energy can be limited as to whatever's necessary for accomplishing a good exit focus or creating that laser cannon like beam, in which case the required ion thruster energy could become relatively minimal for accomplishing an impressive exit ion velocity of 3.26e7 m/s. At times this spacecraft is going to require a hole lot more electrical energy than any cache of Radium to Radon reactor could manage at 32 kw/Ra tonne, or even 320 kw/breeder Ra tonne. However, at a gross spacecraft mass of 4.5e6 tonnes, there's no problem with incorporating an h2o2/aluminum fuel cell of 100 GW.h capacity, or accommodating whatever Lithium nanotube ion battery storage, nuclear reactors or fusion alternatives. Once trekking off into interstellar space, and especially upon getting this craft past our nearest interstellar L1, and of the other gravity pulling us towards the likes of the relatively massive Sirius star/ solar system that we're already in blueshift as headed towards Sirius, as this is when as little as a mdot microgram/sec of Rn222 at the exit velocity of 0.2'c' would be more than sufficient ion thrust for continually accelerating this 4.5e6 tonne spacecraft towards the gravity pull of Sirius. For a one microgram/sec of Rn222 mdot at 0.2'c' example: P = .5e-9 * 3.6e15 = 1.5e6 kgf (1,500 tonnes/s of thrust, or in this case 0.000333 gee) The next problem gets down to the business of continually building up another cache of LRn from the Ra-Rn breeder reactor while on the fly, on behalf of that pesky matter of our having to ion retrothrust long before overshooting the intended target. At 4.5e9 kg, stopping this sucker that's by now going like a bat out of hell (possibly having reached 0.1'c') is going to take some doings. Of course, there would be generations of new and improved minds onboard in order to figure most of this out before arriving into the Sirius star/solar system, not to mention whatever could have been transmitted from Earth over the past century. BTW, at this point of topic argument sake, this mission to Sirius is a one way ticket to ride, with absolutely no travel package guaranties or ticket refunds allowed, because we may not be able to sufficiently retrothrust in order to save any of those brave souls, and a purely gravity-well trajectory turn-around or that of sufficiently aerobraking is at best iffy, although a substantial solar wind parachute as brake might eventually work. Also, recall the sheer size of these required ion thrust nacelles, as being somewhat Star Trek Enterprise like, and for all we know in need of those lithium crystals or perhaps lithium nanotubes as part of their function (after all, any good science fiction uses the regular laws of physics and the best available science, and for all we know lithium could still be part of it). . - Brad Guth I've top-posted for the benefit of others. . - BG |

The Ion Interstellar Spaceship, from Hell to Sirius
Rn222 atoms are another one of those pesky 'use it' or 'lose it' kind
of things. Seems whenever I do my best at uncovering the potential worth of such matters, lo and behold shortly thereafter the Googol/ NOVA Usenet group server bites the dust. ("GOOGLE Server Error" I'm terribly sorry about that) In trying to accomplish my very own math without the help or supposed good wisdom of the all-knowing likes of William Mook, whereas there could be some unintentional errors or even somewhat dyslexic consequences to my deductive but otherwise wishful mindset. So, with your better math and expertise, perhaps contributing whatever comes to your trained mind is what this topic of interstellar ion thrusting needs. If upon average there were merely 150e6 atoms of Rn222 per m3 of air, seems to suggest that a good amount of Ra226 can't be all that too far away. In places the intensity or occurrence of Ra226 that's creating such atoms of Ra222 is of course much greater than 150e6/m3, primarily because radon is a heavy gas is why it hugs the surface or underground at much greater occurrence or population by a good hundred fold = 1.5e10/m3, meaning that in many places the background raw element of Radium(Ra226) is hard at work in the natural decay process, as is naturally making enough Rn222 available for creating and sustaining a good supply of commercial liquid radon (LRn222) for ion thrust applications, into a very doable thing. http://en.wikipedia.org/wiki/Radon "At standard temperature and pressure, radon forms a monoatomic gas with a density of 9.73 kg/m3, about 8 times the surface density of the Earth's atmosphere, 1.217 kg/m3, and is one of the heaviest gases at room temperature and the heaviest of the noble gases (excluding ununoctium). At standard temperature and pressure radon is a colorless gas, but when it is cooled below its freezing point (202 K ; -71 °C ; -96 °F) it has a brilliant phosphorescence which turns yellow as the temperature is lowered, and becomes orange-red at the temperatures air liquefies (below 93 K ; -180 °C). Upon condensation, radon also glows because of the intense radiation it produces." "At standard temperature and pressure, radon forms a monoatomic gas with a density of 9.73 kg/m3" "Radon collects over samples of radium 226 at the rate of around 0.001 cm3/day per g of radium." Therefore, per kg of Ra226 you'll get 1 cm3/day, and per tonne of Ra226 you'll obtain a liter of Rn222 that's worth 9.73 mg, of which doesn't sound like all that much until it's made to exit the ion thruster a 0.5 c, or roughly 150,000 km/s = 219 TN.m or TJ (teraJoules), or if you like 23.34e12 kgf.m of reactive force. Taking this one down to the amount of available ion thrust as formulated upon a continuous thrusting basis, as per fully utilizing that amount of 9.73 mg in Rn222 that's being continually produced per day from a given tonne of radium, that can then be made to produce 23.34e12 kgf.m, whereas if this reactive force were divided by 8.64e4 = 2.7014e8 kgf.s (same as 270.14 thousand tonnes of force per second), of which can further suggest that we might not require nearly as much Ra226 within the breeder reactor of what's creating LRn222, as you might think. Keeping in mind that a reactor core of merely one tonne of Radium (Ra226) isn't even terribly volumetric, although a conventional Thorium reactor as started up with a few rods of Pu238 would likely have to go along for the ride, and as such it too creates a small amount of Radium as the natural process of its decay. So, all and all, there's hardly any shortage of those Rn222 atoms as becoming nifty ions that our electrified thruster/laser cannons can toss out the rear at the 0.5 'c' velocity of 150,000 km/s, eventually giving us the potential 75,000 km/s worth of added trek velocity to our interstellar craft or robotic probe(s). Obviously the existing R&D as to this ion exit velocity is a good thousand fold away from hitting the150,000 km/s mark. However, in a laser cannon pumped format is where such highly energized ions of Rn222 that can be so nicely and efficiently focused or aligned into merging along with the laser beam formulated conduit, as such might reach this goal, if not a little better. This was another one of my 'use it' or 'lose it' mindset notions, as to the likes of utilizing Radium and of the secondary Radon that's already highly charged and going places as is. Seems a darn shame to continually ignore or otherwise waste such a good thing. If you can add a little something in the way of corrections or merely being topic constructive and thus technically informative, have at it. . - Brad Guth |
