Is it ever polite to ask; how little h2o is actually necessary for sustaining an advanced form of intelligent carbon life? (think exoskeletal) If there's not too many Venusian souls in need of cold beer, whereas the existing geothermal toasty and atmosphertic pressure differential as energy resources of Venus are going to more than provide for their needs. Personally, I wouldn't expect to uncover a Venus population of millions, whereas more than likely a few thousand could become the magic number, down to a few hundred as homestead or mining place savers, especially of few souls if most of their really hard work is accomplished via robots. I'm thinking of at most not more than a liter, as perhaps their making do with a 6pack if not otherwise sucking down two of those extra large and fortified beers worth of h2o per 100 kg Venusian per 24 hours, whereas this exoskeletal Venusian isn't hardly going to sweat, especially not at nearly 100 bar, and you likely wouldn't dare pull it out in order **** off the back porch. Without hardly any sweat glands, you'd think a liter of beer might outlast 100 hours per hard working 100 kg Venusian. So, where's the actual demand for all of that h2o? (that's not ever going anywhere except back up into those acidic clouds, where it can once again be easily extracted on demand). At least that's entirely within the regular laws of physics, and otherwise based upon the best available science. .01 liter/hr of h2o or beer per 100 kg exoskeletal soul seems rather doable, don't you think? Of rather easily obtaining that initial fresh supply of h2o from those acidic clouds, the making of such into beer, and of getting that beer cold and keeping it cold is going to demand energy, but once again there's absolutely no such shortage of said energy as long as you're on Venus, and of Venus cloud sucking might even be an ongoing sport, much like skydiving is here on Earth. - Brad Guth As usual, you just don't get it. Anything that functions in Venus's atmosphere is going to be hotter throughout than the "air." You did bring up an amusing image, though. The most common cause of death among Venus beetles with total exoskeletons and a bit of water would be steam explosion. If your 100 bar is correct, that would be one hell of a bang, so maybe death by flying beetle debris would be more common. Just for the heck of it, please do some arithmetic to see if I'm right. Would 900-degree water boil into a 100-bar fluid? |

Lava/mud flows would likely contain their fair share of water, and perhaps even in some degree of such a hot geothermal forced substance hosting h2o2, along with any number of other nifty elements. Otherwise we have those rather serious gas vents of CO2 and S8 to work with, that should also contribute some degree of vaporised h2o along with many other interesting super-heated vapors.

As long as the heat can be removed later. Why of course, as CO2 and S8 are actually rather good elements for accomplishing that task of heat extraction. However, while situated at VL2 is where POOF City could use a little extra internal heat of our PCs running those hot little CPUs. It might be more effective to simply situate a nearby adjustable mirror, one that is outside the Venusian shadow, to direct radiant energy onto the POOF. Two might be employed for symmetry/redundancy. Ever heard of a cold cathode vacuume tube? It seems they can be made extremely small, obviously energy efficient and good for perhaps better than twice whatever that Venusian environment has to share. That cold cathode has a 1600 year half life to boot. http://www.vintagecalculators.com/ht..._dekatron.html I'm not sure what you mean by "extremely small" -- in the case of the Anita Mk8 they appear to be about the same size as the selenium rectifiers. They can never be as small as UV-fabricated MOSFETs on a single silicon chip, though one might contemplate some interesting methods of building a chamber through layering techniques. (The UV-fabricated MOSFETS currently use etching, which won't quite work.) There's no volume or mass restrictions onborad our robotic rigid airships, and there's especially no limitations of any volume or of whatever added mass onboard any such fully manned rigid airship. For getting our surface probes onto that geothermally roasting deck, we'll need extra mass in order to offset the thick atmospheric soup of having 65 kg/m3 worth of buoyancy, as well as for the 90.5% gravity making it even better yet. Just use the glove. Should be sufficient. :-) - Brad Guth -- #191, Useless C++ Programming Idea #7878218: class C { private: virtual void stupid() = 0; }; -- Posted via a free Usenet account from http://www.teranews.com |

Venus is not too hot to touch with the Ovglove

Even that old SR-71 Blackbird at the subfreezing and humanly lethal altitude of 85,000', making mach 3.2 creates an outter skin of 1200 degrees F, thus geting itself much hotter than Venus. So, where's the big insurmountable deal about the geothermally active environment of Venus being a whole lot less hot than what we otherwise deal with and obviously survive on a regular terrestrial basis all the time? That was extra stupid, Crazy Brad. You obviously don't understand that temperature and heat are not the same thing. You know better than that, as well as you know the honest jest of what I'm driving at. You're trying to be funny? Earth's atmosphere is a gigantic heat sink. What's Venus's equivalent? You obviously don't understand that temperature and heat are not the same thing. Earth's atmosphere cannot possibly be a heat sink, as it reradiates the heat later. ;-) -- #191, Linux.
