GPa applications, per say, are in the eye of the beholder, whereas an Earthly LiftPort/ESE beholder's eye can't ever seem to get enough GPa in order to save his or her soul, and that's even if someone other is paying for all of their R&D billions if not trillions.
Composite Fibers are not just for SE Tethers
Exploring Venus with a composite rigid airship
Where necessary having a meter thick insulative skin that's made extensively of the 4.84 GPa basalt fibers (Elastic modulus GPa of 89) and otherwise of basalt micro-balloons, plus a fair percentage of having those not so micro balloons that might as well contain H2 or simply incorporate a good vacuum, is what should obtain the structurally insulative R-1024/m that'll also benefit from the local 65 kg/m3 worth of buoyancy, which should cut the net tonnage or cubic density of that outer hull plus offsetting much of the airship's internal framing and various infrastructure aspects of decks and structured compartments by as great as 50%, though perhaps at first a 25% offset of the total structural consideration that's due to the cubic volumetric buoyancy factor is going to be the case.
Of course the primary buoyancy of it's volumetric shell needn't be nearly as insulative, just made robust and otherwise tough enough in order to take the submarine like pressure of perhaps 2000 psi (138 bar), or perhaps not even 10% of that much if using a displacement gas such as H2 that can be created while on the fly.
Tossing in the 90.5% gravity as yet another attractive factor is what should rather nicely facilitate this form of Venusian exploration as a technological done deal, that which airframe size or total volume of this rigid airship (AKA fat waverider/shuttle) is nearly a none issue except for having to fend off all of the usual mainstream flak that's to be expected from those naysay mindsets that wouldn't so much as accept the truth even if it meant salvaging their own status quo butts.
I believe the necessary R&D on behalf of accomplishing this Venusian rigid airship/(fat waverider/shuttle or whatever robotic probe) isn't even all that insurmountable, as for being terrestrial constructed and fully proof-tested right here on Earth, especially if at first we're talking about a purely robotic application which wouldn't demand 1% of the mass if pertaining to merely sustaining each of the various scientific instrumentation demands.
As far as accomplishing this task robotically, we're not talking about all that large nor aerodynamically configured worth of any such craft (could be just a rigid sphere of an airship), nor would the onboard energy demands be all that daunting. The nicely retrograde weather that's relatively calm below them nifty acidic clouds is actually a rather terrific efficiency consideration that'll nearly always work on behalf of enhancing much of the expedition's navigating considerations, thereby very little propulsion energy is going to be required.
CCD's and other ICs on diamond, or simply employing miniature vacuum tube applications are going to more than function as being entirely within their thermal spec, meaning that little if any auxiliary cooling need be applied.
So, one should be thinking on behalf of robotically flown rigid airships being anything from a few cubic meters to as large as you'd dare to achieve, and of the humanly operated rigid airships of anything from as little as 1,000 m3 to 1,000,000 m3 should be seriously considered.
Unlike having to accomplish our moon, there is nothing about this rigid airship technology that's technically outside the expertise and scope of existing science and proven technology that'll efficiently and safely operate within the Venusian atmosphere, as well as entirely within the regular laws of physics.Extreme high temperature diamond IC's insteasd of merely silicon carbide (SiC) for high temperature semiconductor applications, whereas SiC works perfectly fine even when it's glowing hot, and if the process of doping diamond isn't too pesky is where this element of diamond (C) should take over whenever the SiC application isn't quite sufficient. A less densely populated high temperature rated IC would obviously demand perhaps as great a 10 fold increase in area, therefore a CCD on SiC or C of 50 micron pixels (possibly as tightly populated at 25 micron/pixels) should be doable within existing technology.
Conventional IC gate densities that might achieve 100000 gates/mm2 should become merely 10000 gates/mm2, although I believe 15000 gates/mm2 is entirely doable and at that being way overkill for the Venusian applications that's nearly always operating within something less than the worse case of 811 K.
Within a conventional 0.35 micron process, a gate density of 18000 gates per square millimeter can be achieved, whereas dividing that gate population by a factor of 10 is obviously worthy of laying down 1800 gates/mm2 that'll more than survive the thermal trauma with a few roasting degrees to spare.
What this means is that folks that would rather drop dead than to utilize vacuum tube circuitry that's more than suited to surviving 900 K should be right at home on the toasty range of cruising within the nighttime season of that geothermally roasting Venusian deck, using their SiC or C alternatives in thermally tolerant ICs that are simply less populated devices than the norm. However, since internal probe/airship space and whatever mass isn't hardly a factor, so what's the difference.
In spite of what we've been informed of over and over, Venus is more than technically doable as is.
In spite of what else we've been informed of over and over, our moon via the tethered LSE-CM/ISS is also more than technically doable as is.
Here's a little further update on the composite basalt fiber as offering a perfectly viable LSE tether.
I had previously come to the understanding that if the gravity were 1/6, as such that would be an attractive tether GPa multiplier of 6:1, then if the weight being lifted were of 1/6th, that's obviously another factor of 6:1, thus all toll were looking at 36:1 over the Earthly GPa/density of a basalt tether being 1.8, that's still not even including another offset for the atmospheric loading and punishment, nor the impact of the Van Allen zone of death, as perhaps those two elements should represent at least another factor of 2:1, therefore a the tethered LSE application is where we are at 72:1 and I believe that's only climbing.
By climbing I mean; not that a GPa/density of merely 1.8 is initially all that bad, even for an ESE application, but thinking as to what if some carbon were introduced into the basalt matrix. Perhaps this is another of those conveniently skewed laws of physics that can only work on behalf of the LiftPort/ ESE tether, and not even possible if it's having anything whatsoever to do with accomplishing our moon via the LSE-CM/ISS.
This is also where an Earthly Space Elevator application of anything CNT rope/ribbon or composite tether like, especially that's capable of achieving and sustaining their horrific ESE task at hand, may in fact need to become nearly worth 100 raw fiber GPa if not greater, and even that's highly dependent upon absolutely nothing going terribly wrong, like firstly having to pay the hundreds of billions for it, or secondly some wisecrack Taliban flying any number of aircraft, of dodging various satellites or of avoiding just about any of a thousand other items that are traveling through the same space as their tether occupies, essentially capable of running into such a tether (and don't even rule out ourselves), and perhaps not least of all will always be the horrific radiation impact of mostly the lethal Van Allen zone plus whatever cosmic/solar/lunar influx and the somewhat unavoidably gusty solar wind of electrostatically charged particles that can exceed 2400 km/s, if not reaching 3000 km/s.
Some nice folks, including Brad Edwards, think this LiftPort/ESE tether is going to be a relatively vertical assent, somehow not having to account for the rather horrific atmospheric loading that should place as much as a 1000 mile swoop into the initial climb that's anything but aerodynamic. The aerodynamics imposed upon any such flat ribbon are quite easily demonstrated by replacing that ribbon as attached to your kite, whereas upon using this broad ribbon and, let those silly games begin. Apparently Dr. Edwards and of his upstanding education had missed out on the physics of KITE-101, that subject being sort of pertaining to the absolute chaos of ribbon aerodynamic physics, that's literally flat out of control.
On the other surmountable and thus obtainable opportunity side of our accomplishing what's somewhat of an equally daunting but vastly more doable task that's capable of costing as little as 1% of any LiftPort/ESE, is that of accommodating the Lunar Space Elevator(LSE), although the requirements as well as the priorities per equal or similar task or of the functionality are somewhat altered, though I tend to believe such is very much favorably so, as 3 GPa of relatively well proven and of obviously existing BASALT rope/fiber tether technology is at hand and, darn if that isn't affordably so. Keeping in mind that, I'm not even all that certain a LSE tether will even demand 3 GPa.
On a nasty side note; Unfortunately there's even some room to spare (a little too much actually) for benefiting the likes of our infamous NSA/DoD star-wars technology.
1) 1/6th gravity needs but 1/36th the GPa, thus 3 GPa = an ESE tether of 108 GPa, except that it's also without all the other negative factors associated with any LiftPort/ESE.
2) the tethered LSE-CM/ISS application offers NO atmospheric nor induced harmonic loading; thereby not having induced twisting nor jet-stream oscillations that should be worth at least another 2 fold advantage, thus 2 X 108 = an ESE tether equivalent of 216 GPa.
3) No Van Allen zone of death that's introducing 2^3 Sv/year, and that's only if the entire portion of whatever CNT element is somehow shielded by an impossibly good density worth of 2 g/cm2 and, even that's based upon there being no significant solar maximum events (without sufficient shielding, the raw/naked sustained radiation exposure within that pesky Van Allen zone can reach if not exceed 2^6 Sv/year). Whereas the LSE, of avoiding that nasty little hot-seat of our Van Allen zone should be worth something, like how about avoiding a Van Allen zone GPa loss of perhaps as great as 10%/year, as opposed to the open and relatively clean lunar orbital space taking a toll of perhaps at most 1%/year, and perhaps lesser yet if that tether isn't comprised of such frail CNT molecules. Since the molecular size and related linking bonds required for CNT applications are indeed small or DNA like minute, and thereby extremely dense per say, as opposed to the robust basalt fibers which are continuous, whereas the purely CNT fibers may become easily damaged by the sorts of cosmic and solar debris as well as by the associated horrific radiation (somewhat like how our frail DNA/RNA is so easily damaged beyond repair).
4) No atmospheric induced voltage/energy spikes of somewhat pin-point impacts of at least Giga Joule potential; (the upper potential here is actually tera joules, but at this point whom is counting) by altogether avoiding this sort of tether punishment should be worth something that otherwise any LiftPort/ESE tether simply can't possibly avoid.
5) The total lack of any other orbiting satellites or even of any recorded debris is certainly another LSE plus factor, as opposed to the thousands of known artificial items orbiting Earth, plus a few hundred thousand lesser items of mostly old exploration debris, many of which still remain unrecorded as such, whereas either of which are entirely capable of punching holes or taking serious chunks out of any unshielded CNT tether.
6) A lack of having any lunar based Taliban or other Muslims as running amuck is most certainly another clean break on behalf of the LSE tether, as far away from the reality of our doing just about anything of an Earth based tether application.
7) I certainly can't argue with the fact; the LiftPort/ESE should become a truly great if not spendy thing some day, whereas the LSE-CM/ISS could have been right here and now, at as little as 1% the cost, perhaps all of 10% if having gone for whatever the cost be damned.
The Space Eevator chicken or the egg; Which actually needs to come first, the ESE or the LSE
If it were not for the clear matter of fact as to that of existing Russian rocket technology, of their mostly good and well proven robotic accomplishments that can safely deliver great numbers of payload tonnes as well as any number of brave souls to any such lunar L1 depot, accomplishing such mission transports to or back from the moon within as little as 24 hours seem doable, thus minimizing the worst of human Van Allen zone exposure to less than an hour each way, and of likewise minimizing their open space travel radiation exposure to just that 24 hour allotment.
Earth to LSE-CM/ISS: from what I can learn; worse case of perhaps 10 rem/24 hours is quite survivable by most folks willing to go the distance, whereas 5 rem/day should be a more likely dosage, less yet if this travel time is partially shaded and thus defended by mother Earth, and/or of the LSE-CM/ISS itself residing in lunar nighttime (as more than sufficiently illuminated by relatively safe earthshine) should represent the least possible TBI dosage.
Enabling minimal shielding usage of as little as 5 g/cm2 might actually suffice, which thereby represents that the overall to/from LSE mission passenger module can become extremely volume/space efficient and thereby relatively payload efficient, as well as subsequently rocket energy delivery efficient per kg of whatever crew being delivered to or extracted from the new LSE-CM/ISS depot. This conventional method of crew/passenger delivery is quite obviously still creating some nasty tonnage of global warming CO2 for Earth (most likely somewhat more so polluting per kg than if there were operational LiftPort/ESEs) but, at least it's perfectly doable right here and now, and in volume applications it's certainly capable of becoming affordable at something like $2,500/kg (though I'm certain NASA would insist upon pushing that cost to at least $25,000/kg), plus coming back home is essentially a CO2 free ride and, certainly you don't have to worry if your tether is still in good enough condition or having been thoughtfully targeted by the likes of Usama bin Laden if your return to Earth is somewhat of a shuttle like craft or reentry pod, whereas you can optionally land right at your doorstep (how good is that?).
In case you've missed a little something about the LSE-CM/ISS, this 1.28 km artificial orb that's offering 1^9 m3 of a Borg sphere or cube-like habitat zone is certainly well shielded, as being surrounded by its structure of at least 16 meter or perhaps 20 meters worth of moon dirt filler in the outermost extreme corners of the cube interior, of other areas shielded by at nearly 32 meters, thus insuring a long and healthy existence while onboard. Of course, that's if the CM sphere were only of 1280 meters diameter and, I've already speculated that a CM sphere might otherwise be as large as you'd care to make it, as not only affording further ISS expansion within but, of affording all that much more of the nifty moon dirt on behalf of tending to the needs of others stopping by for their fair share of moon mass, thus affording whatever their mission to hell and back a sufficient cash (thousands of tonnes if need be) of essential substance that'll not only provide damn good radiation shielding but, that of greatly improving their odds of surviving impacts.
Robotic tether pods doing the dirty work of transporting said moon dirt and/or basalt rocks from the lunar surface to the primary CM sphere is certainly going to take but a fraction of any ESE counterpart technology, as well as taking far less energy and, of their not having to contend with any Van Allen zone of death is obviously another good thing incase those pods are hauling your butt to/from the lunar surface. The fact that a lunar nighttime affords an ample window of opportunity for humans to safely goto the lunar surface and perform without being so irradiated to death is certainly another terrific attribute, sort of like the same reason why the Venus nighttime season would have provided such a worthy consideration for those still existing, by their seasonally migrating to sufficiently elevated nighttime sites. Working the moon via earthshine offers way more than sufficient illumination and, of staying warm is technologically far easier to accomplish via any moon-suit than staying cool.
So, when the LiftPort/ESE time actually comes around (another half century from now for assisting in human space travel usage), that even though Earth is nearly burned itself out of its natural/fossil energy reserves, as well as bankrupt and otherwise global warming itself to death by choking upon way too much of it's own CO2, NOx and numerouse other toxic elements, as well as we're still involved with wasting our limited resources and talents on looking for the likes of Usama bin Laden and of all those stealth/invisible WMDs, though for some reason thanking God we've finally got those multi-hundred billion dollar 100+GPa CNT tethers attached to a substantial multi-trillion dollar functioning LiftPoet/ESE version of their CM/ISS depot that's residing itself right smack-dab in the middle of the Van Allen zone of death, whereas this is another example of where I believe having access to the cheap and abundant supply of all that infamous clumping moon dirt that contains He3 is going to come in real handy, as being quite easily and efficiently transported over from the LSE-CM/ISS to their ESE-CM/ISS, as for shielding those individuals within our ESE CM/ISS with at least a sufficient shield surround of 16 meters worth (50t/m2), whereas actually the rather limited amount of perhaps 1024 g/cm2 density was suggested for those Earth L4/L5 cults, whereas the truly hot, hot, hot zone of our mid or even upper Van Allen turf may require at the very least 9 meters worth for any year+ endurance in order to offer those LiftPort ESE/ISS inhabitance 1 rem/year and, perhaps even a little more so shielded if you wanted serious impact protection from all those unfortunate Taliban and/or North Korean and/or retrograde Chinese satellites.
Even my certified mad-scientist plot of sending our existing ISS off to visit the Venusian wizard of Oz at Venus L2 is going to be in serious need of incorporating at least a full meter worth of said moon dirt that'll afford a 335 g/cm2 surround that'll offer the crew and of their fringe passengers a sufficient shield. Of this 24+ month VL2 mission to hell and hopefully back, affording them a fighting chance without their having to rely upon Plan-B, of having to utilize their "banked bone marrow". Obviously, since we don't seems to have a documented technology method of accomplishing manned lunar landings, that remains for this devilish moon dirt snatching process of our having to forfeit this task over to our employing robotics, of which thus far our existing fly-by-rocket robotics can't even manage to launch much of any significant amounts of lunar anything back into orbit, let alone further manage upon station keeping the necessary tonnes of that substance within lunar L1.
Thus I believe the LSE and of it's tethered and robotically managed CM/ISS will ultimately come to the rescue of all those in need, by not only providing a safe abode of 1e9 m3 but as well as offering the most valuable of a substance that's known to space traveling mankind, that of affordably providing access to the necessary tonnage of effective shielding that's intended to abate radiation as well as fending off debris, of accommodating this otherwise difficult task with the absolute least amount of fuss and mission energy taken from others while they safely obtain nearly any amount(s) of moon dirt as provided from a sufficiently stable LSE CM/ISS, that which is obviously going to be a whole lot easier and safer off than of actually accomplishing any sort of lunar landings, subsequently avoiding those energy inefficient and relatively dangerous fly-by-rocket landings and then having to launch off from a downright testy and otherwise very unforgiving lunar surface.
If in fact that relatively poorly reflecting moon dirt and rock turns out being of mostly basalt, then those EMPD thrusters may also become fueled by this terrific substance, thus all any spacecraft needs is a power source of spare electrons, whereas PV or nuclear will do that much, or perhaps having their own space tether dipole element will accommodate this electron gathering process even better.
Dipole energy recovery may only require a few thousand km worth of electrically conducting tethers, one leading and of the other trailing should provide the central energy pod to redistribute this cosmic/solar obtained energy as to driving whatever needy EMPD thruster you've got.
Thinking as positive as one can; Unless our moon turns out being from an entirely other place and time, even so, chances are fairly good that other minerals and of qualified substances that most any EMPD or perhaps Ra-->LRn-->Rn-->ion thruster can utilize as fuel should exist (after all, even the possibility of whatever's sequestered salty moon ice is good for another go), and/or of at least whatever other can be utilized as merely thrusting mass, that which can obviously be obtained from just this sort of 3.35 g/cc dirt depot warehouse in the sky, which might even turn into our very first (God forbid) enterprising for-profit opportunity. Of course, we could have easily started this a couple of decades ago and having been fully operational by at least another decade because, all of the technology and of materials needed have existed since way back then, and surely the laws of physics were the same, as well as I think the necessary Third Reich talents were even there to behold, though having been diverted into more important cold-war agendas, and/or on behalf of implementing the subsequent "spin" and "damage control" for everything Apollo.
Not only can this LSE-CM/ISS provide the extended mission gateway to most other places like the moon itself, Venus, Mars and beyond, but also affording the He3/fusion jackpot payoff as for making all of that happen. Just by obtaining the shielding density alone should be worth at least as much as having to otherwise launch such mass from Earth into orbit and sending it beyond, at NASA's current delivery efficiency of accomplishing roughly $100,000/kg (such as going for any live Mars mission) sort of makes common moon dirt worth a whole bunch more than you or I can count. Seems like, if there's any mineral(s) that can be processed out (by that one I mean as accomplishing such processing on location, as safely within the LSE-CM/ISS by way of extracting from common moon dirt and rocks), is going to become just another rich layer of frosting on the cake, and for anyone to think or suggest otherwise is only self-proclaiming themself as an arrogant fool, or perhaps a much bigger village idiot than even myself, though I have no intentions of giving up that title without a fight.
CNT or BASALT (whom needs a purely CNT tether if you've already got BASALT)
Obviously basalt fibers alone are not going to cut it for any LiftPort/ESE requirement, though maybe there's hope yet, as in utilizing a sufficient taper should more than make the prospect of our using basalt fibers at least worth a consideration of a composite tether of perhaps 10% or even as little as 1% CNT.
Because I'm honestly researching and willing to share in those items of interest, and of ideas based upon implementing certain aspects that could be beneficial; here's more of what I've recently learned about BASALT of all things, learned in part because I simply wanted to know how much basalt rock weighed.
basalt density: a dense mafic rock (Fe and Mg rich silicate, density 2.7 to 2.8g/cc)
I've also, in spite of the opposition, learned that there's a great many complex elements involved within basalt, though I wasn't the least bit prepared to learn of what's been produced out of basalt.
I've learned that basalt based composites can replace steel, of better off than most alloys and of all known reinforced plastics (for example; 1 kg of basalt reinforcement equals roughly 10 kg of steel).
Because the bulk of our planet rock and thereby most likely of that similar to lunar rock is basalt, especially noteworthy as for offering a reflective corresponding index, since as our moon offers such a dark illumination index of roughly 10%, thus besides whatever space gathered debris or volcanic like soot and/or of other sufficiently dark fallout from impacts and/or lava, raw surface basalt exposure seems a rather most likely lunar candidate. So, I was just researching around to learn of how much typical basalt mass there was, in relationship to the supposed lunar mass of 3.35 g/cm3 and, lo and behold, I discovered quite a great deal more than I'd ever needed to know about basalt.
Such as, basalt rock as we generally know of it is roughly 2.9 g/cm3, thus there must be somewhat more substances to our moon than merely basalt, though of this basalt being lighter in mass certainly would help account for it being the bulk/majority of what's covering the lunar surface, even though I've failed to identify upon any of Jay Windley's auto-clumping characteristics nor of its nonreactive aspects, though at least it's reflective index is somewhat close enough as to account for the typical 10% of solar illumination being reflected off the moon.
Here are a just a couple of those extremely interesting basalt related pages:
Basalt Continuous Fiber / Properties Of Basalt Fiber http://www.albarrie.com/Filtration/fil-basalt.htmlhttp://basalt-alf.narod.ru/#_BASALT_STRAND
Basalt Continuous Fiber Mechanical Properties
Tensile strength MPa 4840 (4.84 GPa)
Elastic modulus GPa 89
Elongation at break % 3.15
BTW; "continuous fiber" means exactly what it means, in that if you needed a 100,000 km fiber, that's exactly what you'll get. Not any of those relatively itsy bitsy and horrifically spendy CNT chuncks that'll need to be interlocked and/or chemically bonded.
Seems like I had been wondering all along; what was specifically available for accomplishing a LSE(lunar space elevator) tether and, since those of supposedly superior ESE (Earth Space Elevator) qualifications have been too dumbfounded to bother, or more than likely just plain too dumb and dumber dumbfounded period, I was rather surprised to learn on my very own that basalt fibers even existed, as not only possible but sort of "been there done that" as of many years if not decades ago. As compared to those spendy CNT fibers that may not ever become all that tether usable nor affordably created into existence for decades to come, whereas continuous basalt fibers are not all that difficult to come by, nor of fabricating into all sorts of things. Various basalt molecular properties also seem rather robust, not the least bit cellular/molecular itsy bitsy and thus nearly as radiation frail as those spendy CNT fibers.
Fortunately, the basalt fiber GPa of 4.84 has become a rather good omen, as well as the stability at tension being 95% @200°C and of 82+% @400°C, thus the solar energy spectrum including IR and FIR, imposing as much as 1500 w/m2 is certainly indicating as being yet another plus for the basalt fiber.
Being that I'm thinking along the lines that a raw 3 GPa is more than what's necessary for the LSE tether, even 82% of 4.84 is still 3.97 GPa, though the thermal stress shouldn't ever exceed the 200°C, thereby 95% of 4.84 = 4.6 GPa. Where if the composit fiber density is 2.7 g/cc, that's another solid factor of 1.8:1
Sorry if this basalt fiber information upsets the Starlight Express and of their LiftPort/ESE plans of draining every ounce of Earthly resources, as well as their ongoing efforts at snookering the world continues to create as much CO2 and NOx as possible. I just thought it's interesting as to what one lonely village idiot as myself can actually learn so much, especially if you're not so snookered or part of any assemblage belonging to any one of those NASA/ESE Borg like cults.
However, if you'd care to contribute something of specific properties, or of methods and/or of fiber alternatives, including of those being ESE worthy, as per most anything that's ESE worthy is per chance at least 36 times more than what's necessary for accomplishing the tethered LSE. Since I'm not pretending to being the SE God of tether applicationss, I'll take whatever you've got to work with and, I'll even insure that you receive all the credit or perhaps the blame if you're intending upon bashing anything LSE to death, as opposed to your supporting everything ESE at any cost and apparently at any level of carnage.
Remember folks; I'm not even accounting for what the actual physical threat imposed by the ESE fiasco has to offer Earth inhabitance, as I'll agree that physically there's not all that much direct risk (at least not of where I'm sitting), but of the more than likely trillions of bucks and subsequently all those supposed talents being diverted far away from what has been needed for decades, and of life essential agendas that'll only be further deprived for decades to come, all because of the wasteful endeavors of the likes of those claiming their LiftPort/ESE or bust has to be accommodated or else, apparently even if that means using their Arthur Andersen accounting and ENRON tactics in order to pull it off, along with their cloak of infomercial packaging via NASA talents in order to convince the easily snookered and/or stupified public into paying for all of it, even though at best 0.1% of Earth's population will ever benefit.
Due to all of the ongoing and clearly orchestrated and obviously targeted email trashing that my discoveries and subsequent research has attracted, if you'd like to safely convey something outside of this post, rather than your failing to get through to either of my regular email addresses that may have been recently plugged with bogus and infected files from all of my loyal NASA friends and lovers, you may goto this following public link ("bradguth-email" or include "guthvenus-email" in the subject) and post whatever, or simply call: 1-253-8576061 or 1-253-8575318
No surprise that the following Google email forum "gv-bradguth-email-01" I found been blocked, so try out the next sequence of -02, -03 and so on, or simply create a message of your own using either phrase of "Brad Guth", "bradguth" within the subject, then perhaps I'll find you instead and, don't worry about our crack DHS losing out, as they'll read as well as filter in or out of whatever you or I have to say, as I'm certain they've done so on my telephone conversations.
Other LSE UPDATES:
To further assist those in need of braille visualisation, I soon plan to offer my preliminary 3D mechanical drawing of this LSE-CM/ISS, along with depicting the interactive dynamics of the CCM and of what's situated in between as being those two relatively massive counter rotating tether energised flywheels of at the very least 50t each (though 50,000t seems a whole lot more interesting and worthwhile), thus storing tether dipole energy as well as whatever solar PV energy and subsequently dispensing that energy on demand to operate the entire LSE, plus recharging whomever comes along.
According to the following research paper; http://www.albarrie.com/Filtration/fil-basalt.html
The density of basalt rock is reportedly between 2.8 and 2.9 g/cc. Within a quasi-isotropic composite, basalt fiber becomes nearly three times as intense as E-glass, .59 GPa as opposed to .207 GPa. Whereas it's initial raw fiber GPa of 4.84 is only diminished by 5% at 200°C, as opposed to more than a 100% total failure of anything Spectra.
To even be considering somewhat further upon those thermal properties of Spectra, as suggest by the likes of SE wizard Ian Stirling, seems rather pathetic, or is simply not being the least bit realistic. So, at this juncture I can't be all that confident about Spectra-1000/2000, nor of certain folks specifying anything Spectra as a viable candidate for any space elevator tether (lunar or otherwise), unless that's simply another intentional ruse, as ment for being misleading and/or of disinformation, like most all the other nonsense they've offered, as then I can fully understand their ulterior motives and intentions.
My continuing thoughts upon those basalt fibers; I'm still wondering if a somewhat composite of CNT/basalt could be of something worthy for those ESE huggers, as such would certainly become way overkill for this LSE. However folks, it more than seems reasonable, if the basalt thermal considerations are taken into account, that thermal ability along with the fairly robust molecular properties, plus the tether taper, as then the raw GPa ratio of 4.84/2.7 which equals 1.79 may in fact become sufficient, if not exceed nicely for the LSE application, especially since far less tether over-build will be necessary, as will have to be the case for any tougher GPa product (CNT or better), as needed for the ESE application.
Being that some trther GPa degrade per year from the horrific radiation of the Van Allen zone of death is upon the ESE scene, of a fairly significant portion of the ESE tether, as in day after day, not to mention of what a few hundred thousand speedy projectiles might introduce, whereas none of such issues are those of the LSE consideration, unless perchance those Taliban have recently conquered space travel, which is entirely possible, being that we can't seem to locate Saddam's WMDs nor bin Laden, means that we probably couldn't identify their fleet of spaceships either.
I don't mean to be alarming but, since I was oddly being informed that I should be using Spectra-1000, even though Spectra's melting point is 300°F, offers an unexceptable and highly progressive strength loss above 150°F. This is where the solar impact of 1500 w/m2 is certainly going to become somewhat testy on behalf of any fiber/tether that starts off by losing it's cool at merely 150°F or 66°C. Obviously that's not even an issue with respect to those nifty basalt fibers.
Properties of Basalt and other Selected Fibers:
BASALT FIBRES AS REINFORCEMENT FOR COMPOSITES: This report indicates a composite of basalt and carbon, among a few other elements
Adaptation of Stereolithography to the In-Situ Construction of Lunar Basalt Structures: http://www.freeluna.com/mdmfg.htm
Physical Property of Basalt Fibers:
density = 2.7 g/cc
Best raw GPa = 4.84
Tether GPa = 4.84/2.7 = 1.79
@400°C there's 82% of 4.84 that is still 3.97 GPa, though the thermal stress should't ever exceed the 200°C, thereby 95% of 4.84 offers 4.6 GPa.
If I somewhat better understand this GPa/density (g/cc) consideration, where the basalt fiber offers a GPa/density ratio of 1.8, where I believe that's representative of this tether being of zero taper, the combined tether loading could be 1.8 times it's mass. Of course, that's all based upon constant gravity force as well as for that being of Earth gravity and not of the 1/6th gravity of the moon. Seems like having to calulate upon a constant gravity force, rather than the square of the radious distance and of the initial 1/6th lunar gravity, is not exactly playing fair, at least not by the same rules being applied into their ESE fiasco.
If we were to calculate utilizing 1738 km as the first leg in this lunar space elevator, that's obviously imposing 1/4th the gravity loading at the top, or perhaps upon average 1/2 the loading overall, thus a factor of at least 2:1 if not 3:1. If this tether section offered a taper or mass ratio of 2:1, obviously we've just improved upon the overall loading capacity and we're at least at 4:1. Taking into account the 1/6 gravity to start off with, that's obviously another 6:1 improvement and, all toll we're looking at the Earthly comparable tensile strength/density of being at least 24:1 better off.
If the initial basalt tensile strength/density = 1.8 GPa
If the LSE tether (including gravity and taper) advantage = 24:1
24 * 1.8 = 43.2 LSE GPa, as per using those basalt fibers.
That's not quite as good as I'd hoped for but, seems way more than sufficient.
Taking 95% of that into account for the 200°C factor = 41 LSE GPa.
For some odd notion, I had previously come to the understanding that if the initial gravity were 1/6, as such that would be an attractive tether GPa multiplier of 6:1, then if the weight being lifted were initially of 1/6th, that's obviously another improvement factor of 6:1, thus all toll looking at 36:1 advantage over the Earthly GPa/density of a basalt tether being 1.8, however that's still not even including another offset bonus for excluding the atmospheric loading and punishment, nor avoiding the rather significant impact of the Van Allen zone of death, as perhaps those two elements should represent at least another factor of 2:1, thus creating a LSE application where we're at 72:1 and only climbing above what this is in Earthly terms.
I've come to realize, of many opposing just about everything under the sun, my LSE offers no apparent value(s) to humanity whatsoever, at least in those ESE eyes it's less than worthless, as apparently, or perhaps strangely forbidden, there's no point nor worth whatsoever of accomplishing absolutely anything lunar, as they must think or rather know as a God given fact, that we'll never need easy and affordable access to/from any lunar gateway that offers raw materials, such as for avoiding TBI levels of radiation exposure as well as simply physical shielding, nor even of obtaining raw lunar minerals (even if those are of propellant worthy elements) and, we'll not ever require a safe abode (CM/ISS) away from home but that is always within sight, that's not only a radiation safe habitat, but as highly impact resistant, environmentally self powered via solar and tether dipole energy, along with energy to spare as stored in a pair of counter-rotating 50,000 t flywheels residing at ME-L1 (gravity-well null, or nearly absolute zero G, and least point of friction, where life as a flywheel doesn't get any better).
Apparently, the scary prospect of our actually acquiring a rather essential long-term space environment survival outpost, so that we don't even have to bother with landings on any hostile to life lunar surface, as this CM/ISS outpost is offering a tool and/or means/gateway by which we can deploy any number of individuals and/or tonnage safely off to just about anywhere, is perhaps too much to expect of those intent upon getting their own way or else.
Seems like I could quote any number of respected folks that have long since published on the positive lunar considerations, having to agree with what I've learned, that operating from such a near absolute zero G gateway and of using the least possible energy (if the Earth/moon gravity were properly utilized), numerous satellites can be deployed, as well as for efficiently getting one's self to/from the lunar surface and of whatever underground facilities, thus subsequently making all that lunar substance affordably and safely available to future missions (manned or robotic) as well as for exporting towards Earth, especially invaluable if a few tonnes of that raw lunar material and/or processed product needed to be delivered to the ESE CM.
Perhaps this opportunity has become a little too straight forward, a little too honest, as it's hardly meaningless dribble. For good reason(s), this strange sort of opposition that I've attracted makes myself wonder all the more; why all the orchestrated effort, and/or "spin" and "damage control" on behalf of the status quo, or perhaps it's merely been some of their avoidance that's becoming the most telling. I can understand that if a LSE subject and/or topic of discussion is likely to get yourself in trouble, in misalignment or disfavor with your club membership, then this is obviously as good of reason for such folks to remain as invisible as those infamous WMDs.
While on the other hand, folks like myself are supposed to be unquestionably backing our NASA, as well as accommodating their pet spendy ESE adventurers like Brad Edwards, along with our open checkbooks, for something that'll take decades of R&D plus trillions of hard earned bucks, euros and of whom ever else can be snookered in, while all sorts of ESE teams continue to create global warming via CO2, as well as intent upon providing the ultimate focus for Taliban or just about any such fool looking for revenge against America (at times that's only 90% of the world to be concerned over, of their taking and/or allowing actions against our interest), not to mention having their spendy CNT tether somehow dodge a few hundred thousand pesky impacts per year and, somehow surviving the Van Allen zone of death. All this seems so essential for doing their ESE or bust, in spite of such horrific odds, while systematically excluding whatever the LSE could have been providing for decades.
I don't want to keep being their wet blanket but, seems like we have ourselves a fairly large measure of ESE cult activity brewing, one that's perhaps up to no good, at least no measurable good for the vast bulk of humanity. Though it's true that someday we'll see that ESE and more, even though the rest of us will be swimming in oceans that'll be as much as 10 meters higher and, of what little dry land is left will be extremely expensive as well as tropically downright toasty, unless you've got a nuclear powered air conditioner that'll help convert/process Earth's polluted air into something breathable (CO2-->CO/O2, where the CO element might be reutilized for combustion that'll essentially create more CO2). Under such a global warming trend, Earth well soon become a sister-Venus, with few if any cloud openings and, with most of the available winds trapped within or above those acidic clouds. Though unfortunately, our day/night timeline is simply too quick for accommodating any of us without a personal CONCORD/SST to migrate to where the sun is setting, so we'll simply have to sweat it out.
If I might surmise:
This moon dirt express (MDE or perhaps GMDE if you insist upon associating my name with it), as your typical tethered spece elevators tend to go, this lunar SE is about as good as such things get. The LSE-CM/ISS is far better off, simply far superior than what's only being dreamed about for the ESE and, of the stored flywheel energy that's accumulated within those counter rotating massive wheels is simply more icing on the cake. The interactive CCM that's compensating for the dynamic lunar orbit variance of 5.5% is simply another issue resolved, thus those flywheels remain at nutural at M/E-L1 and of the CM/ISS is nicely regulated at perhaps as far off as M/E-L1.1, or of whatwever's the desired placement. The opportunity of creating and utilizing the electromagnetic energy derived via tether dipole that might reach to within as little as 4r of Earth is yet another good for go solution, or at the very least representing a damn good opportunity of easily extracting terajoules of squeaky clean energy on the fly.
BTW; at least my initial MDE (Moon Dirt Express) or GMDE is configured with two or more tethers (lunar anchors of perhaps 1000 km apart), thereby you can plan on doubling your pleasure, where having two LSE tethers per CM/ISS is certainly improving the overall capacity by double, but also improving those odds of having that alternative should we manage to shoot one of our own tethers out from under our own feet. As long as the LSE tethers are accommodating far more than they're impacting and, that such tethers are relatively cheap, as in made on location from lunar basalt (in rather extreme atmospheric vacuum purity) and thereby zip worth of delivery cost, seems like the more tethers per CM/ISS the better.
NOTE: the prospect of manufacturing those basalt fibers while on location, as specifically for the LSE tether application (not to exclude exporting such a nifty product), if that process should happen to create volumes of CO2, as well as just about any other nasty impurities as process eliminations, so what's the difference. As far as I know, there's none of those pesky protestors against lunar pollution anywhere in sight, and even if there were, our crack Boeing/TRW Phantom Works ABL team could use them for a little target practice. (I'm just kidding)
If my math seems skewed, it's certainly not intentional, just my village idiot nature of having to make due and by learning on the fly, and of my favoring towards the positive side of things, those which I believe can be affordably accomplished with what we've got, at least until others inform me how far off I am. Usually, it's just that my terminology and reverse engineering that doesn't suit their methodology, though I'm actually somewhat exactly like all those ESE huggers, as well as Hubble huggers and don't ever forget SETI, as these mostly nice but deluded folks are always touting their positive aspects, while seldom if ever relating to the truthful budget deficits of their quest, nor of environmental as well as human carnage impact associated with their endeavors. Question any of their science, or moral reasoning and/or math, such as pertaining to anything ESE and, these folks tend to go absolutely ballistic.
Attention NSA/DoD, and even their puppet DHS:
This LSE-CM/ISS outpost could certainly become the ultimate laser cannon deployment for defending Earth from the likes of Taliban, or even from those throughly pissed-off Venus Cathars. A 100 GW laser cannon from the likes of Raytheon/TRW, at 0.5 milliradian or better could certainly do this trick. If North Korea ever decided to attempt much of anything, with that much laser-beam energy we could nullify just about any acre of their land into lava. Having a 300 meter CM sphere hosting the 1^6 m3 of ISS abode could certainly accommodate just about any size laser cannon you could think of and, tether power derived via EMF, along with storing that energy within those massive (50,000 t flywheels), should more than energise it. In addition, here's another warm and fuzzy thought; we could just as well easily spike that mostly IR laser cannon with mercury, that way we'd be able to deliver essentially an invisible WMD of mostly UV/b or even UV/c (193 nm), thus invisibly ripping their internal DNA/RNA to shreds, thus allowing their own immune system to devour our enemies from within, sort of like inducing cancer on steroids, except there'd be absolutely no specific signature nor trace of what hit them (I believe that's even better than God).
