As long as I’m crazy enough to be proposing the use of our moon in order to geoengineer a way out of our GW/AGW mess, we might as well consider directly utilizing the moon itself.
Our moon has been shrinking and/or deflating as it cools (roughly 100 nm/year) and further solidifies, so we might as well take full advantage of whatever's inside of its extremely thick and robust crust of paramagnetic basalt that’s highly fused and protecting the inverted density of whatever’s within its thick shell. At 7.35e22 kg, our moon is definitely a heavy sucker that’s perhaps only 0.1% hollow or porous as is. However, besides our desperate need of creating interactive shade for geoengineering our GW and AGW problems away, Earth can always use minerals and precious metals or rear-earths, and what could possibly be more rare-earth than our paramagnetic moon. So, before and/or during the relocation process of gradually moving our moon out to Earth L1 where it’ll be interactively maintained as our station keeping shade, we should also tunnel into and mine out that moon to the tune of at least extracting 10%, leaving us with a 6.615e22 kg moon that’s nicely hollowed out below that extremely thick and highly protective crust. Actually most of that tunnel excavated mass would remain with the moon, as well as converted into basalt tether fibers and otherwise utilized for the 2xL2 centripetal mass that’s necessary for pulling that moon further away. This vertical tunnel of 12 meters diameter (or if you like as tight as 4 meters) and the interior excavation process leaves us with an extra or surplus 2.5e19 m3 of vacant space, in addition to all that’s otherwise exposed as naturally hollow and/or porous about our moon. Giving everyone a volume of 1e9 m3 or one km3 is enough to accommodate 25 billion of us humans in relative safety (in some ways better than anyplace on Earth could provide, because the crust of Earth is relatively thin, broken and very unstable). I’m certain that others here in this Geoengineering Group of expertise can muster up creative alternatives and/or suggest better utilizations, but just to kick this moon relocation topic up a spare notch or two is what I’ve intended by suggesting this excavation process that offers many advantages besides providing for the tethers and most of the tethered tug mass that’s going to gradually pull our moon further away from Earth. Just tunneling in at 12 meters diameter through 60 km of its fused paramagnetic basalt crust is going to be worth excavating 21e6 tonnes that could be utilized for all sorts of benefits (including oxygen and water), whereas processing surface basalt plus assorted crater rubble that’s in no short supply, and loads of dust should also give us tonnes of valuable He3 that’ll make everything profitable all by itself. http://translate.google.com/# Brad Guth, Brad_Guth, Brad.Guth, BradGuth, BG / “Guth Usenet” On Feb 5, 10:22 am, BradGuth <[email protected]> wrote: > It's not as hard as you might think, and we'd get up to 3.5% shade, > although that could easily be adjusted to suit, and there are a few > other benefits besides terrific job security for at least a century. > > http://translate.google.com/# > Brad Guth, Brad_Guth, Brad.Guth, BradGuth, BG / “Guth Usenet” -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
