In this summary attempt, I'll try hardest to focus upon the positive issues of applying the Quantum-Binary Packet technology that's at hand and, of the hopefully conservative outcome of applying such for interplanetary communications, without all the filler and favor of my having to return all of your warm and fuzzy flak.
Another recent learn is that derived from the Light Measurement Handbook of the photon energy level for what 400 nm represents is at least 10 fold greater photon energy than what the 1550 nm of IR spectrum delivers. I'm assuming this is another good thing, especially if those 365~425 nm photons were being observed by a stuborn nocturnal sort of heathen that's refusing to die off simply because it gotten a little toasty, having a magnitude 5 visual nocturnal sensitivity advantage over what most any human sight can obtain, not to mention of what any good photon detector might deliver in order to record a significant signal to noise (s/n) ratio, of which there should not be all that much nighttime background illumination noise within the area of 365~425 nm, least not that's been created from any Earthshine, especially when the bulk of our O2 and O3 absorbs rather than deflects solar UV.
Based upon utilizing the 0.5 milliradian source as for planet to planet efforts, even if that were exiting Earth's atmosphere at merely 5 watts and by the distance of 25^6 miles (40.25^6 km) diverging that beam as to covering the target radius of 351.5 km equals a relatively broad area or zone of 388^9 m2.
NOTE: The amount of photon losses associated in getting this 5 watts away from Earth is not something I have any absolute calculation upon but, it's certainly not insurmountable, as in 50% loss would obviously entail using a pair of 5 watt lasers or one unit of 10 watt delivery and, this actually might turn out being a relatively slight factor (very much so within available technology). Once 5 watts exits Earth's atmosphere (say we manage to obtain this at 0.5 milliradian, of which might necessitate a 0.1 milliradian initial beam or merely a of multiple .05 milliradian lasers spread out over a few hundred miles), there's damn little in further divergence until those photons impact with the sufficiently near UV transparent clouds of Venus.
If we were to be considering the near UV of 400 nm, if we were to utilize such in the amount of 684 lumens/w/m2 (lux/watt) and of there being supposedly 10^28 photons/lux (5*684*10^28 = 34.20^30), where I believe that'a a grand total of 34.2^30/388^9 = 88^18 photons/s/m2 as spread equally over each of those cloud top 388^9 m2, roughly a target diameter 703 km illuminated flood upon the top side of those clouds and subsequently, not likely diverged to more than 775 km on the cloud bottoms. In one reference to Earth's surface illumination, the Venus daylight cloud transparency of white light (sulphur crystal filtered as sort of becoming yellowish below those clouds) is reportedly 4% (100 w/m2) of the total solar influx of 2650 w/m2, with nearly zero IR making itself past the first few km of cloud depth, not to mention having to overcome roughly 80% of the longwave spectrum within Earthshine (one estimate offers 450 w/m2) as being illumination background which could be nearly saturation (thus any laser of IR seems nearly worthless unless we're talking about implement a Boeing/TRW GW class laser cannon, in which case we might only seriously aggravate whatever's looking back at Earth, especially if that's a clear shot from their metro astronomy airship cruising above those nighttime clouds).
Here's another outline of making this laser communications happen:
0.5 milliradian source (near UV 365~450 nm)
Exiting Earth's atmosphere at 5w/m2
Total photon output (w*l*10^28) = 34.2^30
Free space distance of 25 million miles (40.25^6 km)
Target radius of 351.5 km (diameter of 703 km)
Target area of 388^9 m2 (top of Venus clouds)
Photon Luminance per m2 of 88^18 photons (top of clouds)
Cloud transparency of near UV = 10% (estimate)
Bottom of cloud luminance = 8.8^18 photons/s/m2
Just for a little further argument sake; let us presume that of those cloud top illuminations of the 703 km diameter zone of 388^9 m2 is further diverged so that the observed bottom cloud illumination is essentially covering twice that area (776^9 m2), that becoming an entire sky that's fully illuminated, as roughly a 170° FOV, then to be adding further insult to injury by assuming a pathetic near UV transparency of merely 1% (of which of course it isn't nearly that bad), that's still 4.4^17 photons/s/m2 of 400 nm illumination (presumably that initial 400 nm would include sidebands of at least +/- 25 nm).
In other words, worse case scenario of our having to divide those 4.4^17 photons by 1 gb = 4.4^8 photons/bit, and perhaps further knocking off another batch of those photons because those nocturnals are legally blind and/or their photon detecting technology isn't worth squat, places 4.4^6 photons per bit and, that's of delivering a 1 gbps packet throughput that's otherwise appearing as a one second illumination to the biological (eye) sensor. As for dividing that by another factor of 20 for delivering those as 50 ms 1/0 illuminations and we're still at 0.22^6 or 220 thousand photons per bit. Good grief all mighty folks, that's certainly something far better off than any 10 photons/bit. And as for regarding background photon noise, (what noise?) it's nearly as absolutely pitch black along with their only significant influx being of Earthshine which offers nearly zip worth of anything UV, unless it's been artificially created and, as whatever UV of other starshine isn't likely to represent 1% of Earthshine, especially when we're mutually at near juncture (+/- 30 days).
If the fully UV lux/watt becomes lesser (as would reportedly be the case by way of applying more into UV/a or b rather than using near UV) then supposedly those numbers of photons will become less. However, 88^18 photons/m2 on top of those clouds and even 4.4^17 photons/m2 below seems to offer some if not a great deal of room to spare, as that's based upon a mere 1 m2 collector concentrating those photons down to the 1 mm2 sensor and, there's absolutely nothing stopping anyone from utilizing 10 m2, 100 m2 or even 1000 m2 worth of collector, as what does size have to do with anything except as for making the prospect even better off (certainly not worse). I believe the prime discovery image is indicating upon somewhat substantial parabolic signatures, at least one of which is facing upward with a central tower or mast that just so happens to be rather huge by Earth standards.
Some of those lumen/photon losses by going more UV/a (say 365 nm) will alternately result in a greater percentage of those photons exiting Earth but, that's also more so of importance as to their increased transmission through those nighttime clouds of Venus, picking up improvements of having an overall UV transparency that's potentially exceeding 10% and, the more into the UV spectrum the better that photon throughput seems to get (solar UV exposure being another darn good reason for any nocturnal form of other life NOT as we know it to migrate so as to remain within their season of nighttime) and, of most likely still being visible (>320+nm) to a sufficiently evolved nocturnal sort, and of most certainly detectable by way of technology. Of course, that technology may not yet be Venus originated, as certainly there's no reason for radio within the equation of their surviving a greenhouse environment (until little more than 150 or so years ago, our pathetic Earth had no stinking radio, thus representing not 0.0001% of discovered human history), thereby an interactive surface transponder may need to be deployed on their behalf, where that instrument can certainly be of UV laser transponder and/or of conventional microwave transceiver offering interactive audio/video format, of which obviously may need to apply some heat exchanging of which previous probes had virtually none of, thus having to exist within a roasting daylight and relatively low elevation "death valley" environment, as in "duh", they fried within an hour or so.
Fortunately, today we have a number of components of substantially greater thermal stamina (plasma screens, recent solid state components that'll operate continue to operate at 1/10th the electrical demand and even electro-mechanical devices that'll withstand all that Venus can deliver and then some) and besides all of that, I've noted on other research where there's lots of energy for heat transfer that may be easily acquired from just the available pressure and thermal differentials that makes vertical wind kinetics into a rather robust and reliable energy solution, one that essentially likes all the heat it can get, up to a relatively high threshold, whereas the more heat there is the better and, where currently that upper thermal limit is at least 100°K above worst possible case environment impact and otherwise nearly 200°K above their nighttime environment of being at 5+km, thus powerful motor/generators are no longer an issue, in fact the toasty CO2 environment is even better off than Earth's atmosphere for such testy heat transfers as well as for there being absolutely no corrosion whatsoever.
Surely others claiming as being smart must realize that I've contributed more than my fair share of good ideas along with a few too many bad ones, along with my dyslexic syntax and creative grammar is perhaps just a test to see if you're actually awake and/or any good at reverse syntax decryption.
Besides my initial observational discoveries, as those I acquired from the terrific Magellan SAR images, of which all of astronomy and astrophysics wants nothing more of but to disqualify upon every possible count, of which I'm still waiting to hear their alternate qualifications as for everything that exist on Venus being so entirely natural (so far no cigar), where as promised I'll post links to any of their superior geological references and/or alternative research (oddly, so far there's been no takers). In addition to the worthy sightings of what still looks a whole lot more artificial than not, I've accomplished a fairly substantial list of my considering upon other positives, where there's been little need as for my portraying whatever's negative because, nearly the entire world of NASA's moderated Borg collectives of astronomy and astrophysics has that one (negative) covered hands down. So, if you need to be reaffirmed as to what's so absolutely negative of Venus, just goto NASA or of any of their collective partners in crime and you'll get loads of their tax supported infomercial crap.
Besides accomplishing interplanetary communications for two cents on the dollar as compared to just about anything other that's NASA; I'll offer the following tit for tats as reminders.
Nocturnal communications and thereby intelligence may have become nearly if not entirely visual, perceptive above the near UV as well as reaching well into perceiving fully UV/a.
Rigid airship buoyancy (65+kg/m3 and even more so buoyant at nighttime when their atmosphere is some 6+% cooler and thus 6% denser).
Of natural energy availability is somewhat of an overload, as for taking your pick of several viable alternatives and, of no limits as far as I can tell.
CO2-->CO/O2 seems to have also become another "done deal", at least if you're sufficiently motivated, especially where it's getting hotter every year.
As of lately, Venus has not been getting itself hotter, if anything it's becoming cooler, thus whatever solar energy input equals nighttime energy out and then some.
Life NOT as we know it; this one is almost too easy, as the environment pressure increases, the O2 demand decreases (rather substantially).
Planetary evolution; even if that were expedited by a factor of 0.1°K/year, that's still taking 4200 years of shifting from 300°K to 720°K.
Physiological evolution (Darwin style) has always been a surprise as to what's discovered on Earth, of substantial life existing where mere humans can't.
Fluid or liquid vapor phase stability; this too is almost understood by even this village idiot (heat is something that's relative to pressure).
Pure H2O extraction from those sulphuric clouds is chemistry/physics 101, couldn't be simpler nor more efficient via vacuum distillation.
Converting H2O into H2O2 for safe keeping, subsequently extracting H2 on demand is hardly even worth arguing about.
There's no surface exposure to significantly harmful radiation, thanks mostly to that terrific atmosphere and those thick clouds, whereas nighttime is only better off and absolutely dark to a mere human, whereas any good nocturnal probably sees just fine and dandy, or is in need of less than a watt of energy (biological or otherwise) in order to sufficiently illuminate their environment (xenon/CO2 illumination is actually quite efficient).
R-256 insulation; simply not any problem whatsoever, especially if that's via 1 bar worth of H2 displaced spheres, those microspheres being surrounded by N2 that's also rather buoyant.
Site construction; as from massive rock quarries and of whatever that large rigid airship could assist (weight seems not a significant factor).
Local surface roads or rail beds, if needing a suspension bridge in order to span a significant canyon or rill, that's no sweat.
Massive above surface reservoirs, filled via an extended fluid-aqueduct associated with yet another fluid holding basin that's clearly in the picture (go figure otherwise).
In need a hot township, as in somewhere to hang your thermal coveralls, there's lots of high rise structures to pick from and, they're damn big.
Need an aerodynamic suited tarmac, along with service sub-bays, as situated right next to your toasty township (go figure out what other that attribute represents).
Realizing that it's best being near to something geologically active, how about that being a nearby fluid arch (does that qualify?).
For solar energy or perhaps UV astronomy research, a few large parabolics might be rather nice to have (go figure otherwise, as obviously surface based optics aren't worth squat).
Rigid airship astronomy; science and physics says it'll work quite nicely, placing substantial optics well above those nighttime clouds.
Life supportive migrations for remaining within their season of nighttime, for that there's at least two sites spotted at 180° from No.1
Storage of fluids, including H2O, H2O2, H2, CO, O2 and C12H26; how about those two rows of recessed spheres, of being substantial volume enough to do the trick and then some.
I could certainly go on and on but, isn't this getting absolutely ridiculous. I mean, how pathetically braille are NASA's image interpreters, or are they only capable of identifying invisible WMDs?
I've also introduced something other that's humanitarian worthy of our NSA/DoD laser cannon, as having to do with utilizing that nifty Boeing/TRW laser cannon for other than for target practicing upon shuttles. By injecting a little mercury and we've got ourselves a somewhat serious long distance (prepaid) UV calling plan that's already on line and cruising at 40,000'. However, a lot of mercury mixed in with CO2 and we've got ourselves a truly super lethal DNA/RNA chopping death-ray, as an extermination machine that'll otherwise leave it's victim and/or their machinery intact, while the internal biology of the victim is being thoughtfully ravaged to death by it's own immune system. This is not my saying there's anything unhumanitarian about destroying a missile that's on it's way to either of our homes, as that's also about as humanitarian as it gets, I'm just considering that perhaps we can achieve both goals with the same death ray or perhaps a conservative usage for interplanetary communications could even be in the cards.
Now that's it's become literally too bloody late for my offer of pink-slip dispensing, on behalf of COLUMBIA and of focusing what's left of NASA, towards achieving obtainable goals and ultimately saving us taxpayers billions (actually trillions), where I seem to recall having offered to do that nasty little job of payroll reductions for a messily 1% commission per payroll position, though oddly I wasn't contacted by anyone within NASA and, I'll just bet that no one from NASA ever bothered to forward my offer to their Senate Appropriations, of those snookered fools encharge of whatever budget if any that our beloved NASA gets.
Unlike the absolutely lethal UV/c (193 nm) aspects of NSA/DoD laser cannon technologies being developed by Boeing's Phantom Works and TRW, at least my near UV or even that of the 365 nm spectrum are only somewhat superficially dangerous if given substantial exposure, though still that's representing nothing that's sufficiently penetrating so as to cause internal organ's to having their DNA/RNA impacted, thus fortunately these multiple 5 watt/second packets of perhaps eventually becoming 1 ms durations at 0.5 milliradian will likely more than suffice, with little or no detectable biological impact other than being visually observed by nocturnal sorts of ETs, whereas too much of these 365 nm photons could damage biological rods and cones of such sensitive nocturnal eyes (there are certain physiological limits of which I'm learning about, by way of that nifty "need to know" basis, that may even coexist within just such a hot and nasty environment).
I realize that it's apparently become my obligation to helping out the blind but really, is it wise for this village idiot to be pointing out all there is that's been all along so freaking positive about Venus?
Any fool already knows it's sufficiently hot and nasty on Venus (at least for the likes of frail Earth humans), just as that same fool must have known prior to this last spendy Mars probe, that whatever is Mars is truly of being quite dry-ice frozen and otherwise seriously irradiated to death and, if not already sufficiently dead, then the absolute last thing we'll need back here on Earth are any of those anti-freeze radiation proof Mars microbes, as we can't hardly manage with what we've got. Remember folks; even though the Mars radiation environment is supposedly a walk in the park as compared to our lunar radiation, Mars as been declared as humanly lethal by those very same folks supporting our otherwise radiation proof hybrid Apollo astronauts, as for otherwise being known for accomplishing the most out of this world worst possible documentary/survey photography and, apparently even using such piss poor KODAK film to boot that couldn't possibly have recorded stars, so insensitive that neither was that film measurably fogged after 2 weeks of extreme exposure, some of that exposure having to survive 36 hours worth of EVA within little more than a beer can worth of shielding.
BTW; as long as some of you diehard cloak and dagger folks want to play tough and absolutely negative about absolutely anything moon or Venus, and as for speaking of those lunar negatives, as in or crack astronaust going to the moon and not bothering to photographing those vibrant stars over the supposedly asphalt or perhaps basalt reflective lunar horizon would be like Lewis and Clark not bothering to document the Pacific Ocean, or of going to Niagara Falls and not bothering to photograph the falls, or how about going to Coulee and not photographing the Grand Coulee Dam, except this one is far worse because, the taxpayers paid more than a million bucks for each and every one of those Apollo/lunar photo negatives and, we've been paying ever since, some of us with our blood, many more so of the USSR and of any other country getting in our way have paid their ultimate price.
