    By the way Landis' idea about CaCl2 is not totally unworkable. It's unworkable in the FFC Cambridge process sense, where you keep adding solid chunks of oxides/rocks that get reduced by the dissolved metallic calcium in the molten calcium chloride salt - there is a continuous buildup of oxygen in the melt, as CaO, which is not very fusible, and you emit the chlorine gas at the anode, so you have an unstable molten bath that needs constant replacing/regeneration. One way to recycle the bath is to bubble HCl through it, but it cannot be done small steps at a time during electrolysis, because the metallic calcium dissolved in the salt will react Ca+HCl-->CaCl2 + H2 gas, in preference to your preferred reaction of CaO+HCl-->CaCl2+H2O vapor. A more elegant way is to not mess with an unstable bath, but electrolyze pure CaCl2 for Ca and Cl2, burn the Cl2+H2-->HCl, react the HCl + CaO--> CaCl2 + H2O, dry the CaCl2, and electrolyze the H2O-->H2+O2, you got your O2 and recycle to H2 to burn more Cl2. The advantage of the CaCl2 method is that it's lower temp than CaF2, so easier material constraints, but that may be a disadvantage if you want to distill out the metallic calcium, as with a molten CaCl2 electrolysis you can never get 100% coulombic efficiency, because some metal will redissolve and wander back to the anode and react with the gases evolved there, even if you apply that stick-drawing trick to only let the tip of the metal hang into the molten salt, to save it from dissolving away, As far as the FFC Cambridge method goes, it works ok to take a fistful of oxide and reduce it to metal (after you electrolyzed enough to build up the dissolved metallic calcium concentration in the liquid salt), but on an industrial scale it's simpler to just get the metallic calcium out of a stable and productive process, granulate the calcium metal, pulverize the oxide, stir the two together and ignite the calcium thermite (Goldschmidt-like, Al-Cr-like) reaction. It's hard to get much new intellectual property innovation in inorganic chemistry that hasn't already been tried, but organometallic catalysis at room temperature is pretty promising. In particular room temperature N2 fixation from the atmosphere would be nice.

    Also, from a calcium reduction you'd recuperate the slag that contains all the oxygen, but the metalloid residue, containing silicon, aluminum, iron, sodium, potassium, magnesium, and especially titanium(lightweight strong like steel), is valuable too. Down here on Earth we have carbochlorination to get TiCl4 and SiCl4 liquids ready for distillation purification, but up on the Moon there might be a carbon shortage, and then you can use calciochlorination instead, but you have to do the steps separately, because unlike carbon+chlorine nonreacting with each other, calcium loves to react with chlorine. Silicon, titanium, aluminum, iron, magnesium/Na/K chlorides are easy to separate by fractional distillation (magnesium+alkali metal chlorides being the bottoms), though good luck running such a process, trying to not block up the conduits with unmolten magnesium/sodium chloride crust. Water can be an aid to unblock almost blocked passages, Some of the magnesium might react with the water during the slag extraction step, so during the thermite reaction it's best to let the magnesium/sodium/potassium distill off, then collect it in a remote portion of the reaction retort (if not enough excess Ca, at the tip of the retort it may be magnesium/sodium/potassium sulfide of phosphide with free sulfur and phosphorous, but most likely S and P end up as calcium salts, then as H2S and PH3 on water extraction). Some of the aluminum will react too under high pH quicklime conditions, but it shouldn't be too bad, and if it is, there might be other solvents that are between water and alcohol that dissolve the calcium oxide, but don't react with Mg and Al, maybe not even with Na, K. It's best to distill the Na, K, Mg out as metal first before water extraction of the slag.

    Some of the unreacted metallic slag could be shaped into small rods and used in a solar powered or nuclear powered nailgun propulsion system to get stuff off the surface of the Moon into outer space, then recollected for later use, so they should be built nonaerodynamic but flat impact shape so they don't bury deep into the lunar surface and can be picked up for reuse. Steering becomes a huge issue with such propulsion, because you have to shoot these things towards a predefined location, not just anywhere, so you still need gaseous steering emissions, such as high temperature/pressure oxygen gas you made out of moonrock.

    Oh, btw, if you're going to do the iridium anode/CaF2/CaO electrolysis, the calcium has to be distilled off at the cathode, otherwise it loves to dissolve back into the salt as some monovalent ion and go to the anode and react with the gaseous oxygen there. Present industrial Ca production uses aluminum vacuum distillation of the oxide, similar in concept to the ferrosilicon silicothermic Mg production named Pidgeon process, because of the redissolution issues of Ca salt electrolysis (such issues are not prevalent with alkali metals, as they can't go to half valent from monovalent, or even Mg electrolysis probably doesn't have this issue.) There is a section in the 1911 Encyclopedia Britannica talking about calcium electrolysis with continuously raised rods, and the Ca metal forms as a stick, as a bar, and being held above the liquid salt, it does not dissolve back too much, as long as the rate of deposition is faster than the local redissolution at the tip of such stick. So the best idea at the high melting point of CaF2 is to distill off the Ca metal instead of having it as a stick, and then if the cathode is under vacuum, the anode has to be too, and you'd get the oxygen out as a very high temperature vacuum gas. But the device may nevertheless be small scale, because of the superhigh electric conductivity of a molten salt and high reaction rates at such huge temperatures, only this vacuum consideration adds some volume, but not that much weight.

If you could get the O2 out of the Moon's silicate rock, you could save rocket weight by an order of magnitude. NASA had a competition challenge back in like 2002 about this, it expired a while ago, but I been thinkin about it.

    Geoffrey A Landis at Nasa came to a natural conclusion that Calcium reduction is a catchall method to treat any rock, as shown at http://lib.znate.ru/pars_docs/... You could do a thermite-like reaction with excess metallic calcium and get calcium oxide plus silicon, aluminum, magnesium(evaporated), iron, etc. You don't need a huge device for that, as astronauts might play around with it out in the open Moon surface as shown by this thermite reaction http://www.youtube.com/watch?v... (thermite railroad welding) or https://www.youtube.com/watch?... (thermite out on grass and bricks). Calcium will do a thermite reaction stronger than aluminum with everything (magnesium might be difficult, barium and calcium stay as oxides (which is OK), but aluminum and silicon, the bulk or rocks, and especially iron, should be OK.) So GA Landis' problem is still how to get O2 out of the CaO, and his best process is CaCl2/CaO melt. That has huge issues, the biggest being that it is Cl2 not O2 that comes out of that melt if electrolyzed. A CaF2/CaO mix might work, but now you're talking huge temperatures to melt that. An Iridium crucible and Iridium anode (for cathode there are many options) with a CaF2/CaO electrolyte might be workable, which might be the reason for the iridium signature from the dinosaur extinction layer is geological rocks - it might have been a spaceship full of tiny alien creatures destroying their ship Jabal al Tariq (ibn Ziyad) style (from whom Gibr Al Tar iq is named.), after some 70,000 year trip, millions of years ago, before humans or even monkeys ever stepped foot on this planet. Iridium is almost the heaviest thing in the world around us, with some uncertainty about osmium. To maintain high enough heat some of the electric energy has to be used to melt the CaF2/O mix, similar to the calcium carbide making electric furnace, and the expensive fluoride needs very careful recycling, including distillation of the metal Ca, or amalgam extraction (in which case now you got a Hg recycling problem), or who knows what.

    Another option is dissolving CaO in water, as quicklime, and electrolyzing that, as Sir Humphry Davy did 200+ years ago when first making metallic calcium on this planet. The problem of this aqueous electrolysis is conductivity compared to a molten salt, therefore production rate/scale of device, but on the other hand it can be conducted at low temperature, and mercury recycling issues might be smaller than fluoride recycling issues out of calcium metal, especially once you extract the amalgam the following way: Davy distilled off the mercury, and as only like 0.5% or less can be a liquid amalgam, that's a huge amount of distillation energy wa

I just thought about this a little more. The wind itself does not blow away the atmosphere, as in physically blow it away, because a particle impacting the upper atmosphere at high speed is like a super fast ball inside a lottery urn, or when breaking in pool, the initial ball at high velocity, its velocity gets transferred and distributed over to the other particles of the atmosphere, raising the temperature, but not really knocking anything off the planet's surface. There is probably a dynamic equilibrium of the size of the atmosphere, a balance between particles captured and lost, particles captured by gravity from the solar wind, and lost from gravity if they ever reach the escape velocity from random thermal motions (the Maxwell Boltzmann velocity distribution of gas molecules has a sizable tail in the high velocity region) in the very upper zones of the atmosphere. The temperature in the troposphere matters the most, and the higher the troposphere the colder the temperature, the more it retains the atmosphere, and the troposphere becomes even higher, so the size of the atmosphere may be very sensitive to temperature, and has to be in a very narrow range to retain all nitrogen and oxygen and CO2, but let hydrogen fully escape (else you have an explosion in the atmosphere from a lightning strike, or can never build up much oxygen because it keeps turning to water from the captured hydrogen). Too cold a troposphere may retain too much hydrogen. In fact the gas giants Jupiter, Saturn, Neptune and Uranus are probably silicate cored just like Earth, might have water too if they have lightning strikes, but they have so much gravity and sufficiently low troposphere temperature they retain all the hydrogen, increasing gravity which retains even more hydrogen, and this process would go on indefinitely weren't it for the fact that there is so little hydrogen in outer space, it takes forever to grow a millimeter for the size of the planet. These gas giants are probably growing, and the closer they are to the solar wind source, the Sun, the faster they must be growing, Jupiter growing faster than Saturn, etc, if the hydrogen concentration decreases in outer space when going farther from the Sun. In fact the silicate core of Jupiter might have started off about the same size as Earth, but because it was so much lower temperature in its troposphere, it retained the hydrogen and it grew into a massive gravity object which now heavily attracts all kinds of meteorites and comets, so its silicate core is probably much bigger now than Earth's. So anyway, what I was trying to say at first was that Venus may not need a magnetic field if its temperature is low enough, the atmosphere may absorb the impact of the solar wind, as long as the fully dispersed diffuse Aurora Borealis phenomenon across even the equator happens deep enough in the atmosphere that the hot particles impact colder ones above and lose their escape velocity, and never escape. It's very hard to create a natural magnetic field if you don't even understand why such a thing arises. It might have to do with a huge nickel-iron core, and if Venus lacks that, that's very expensive to gather in outer space and dump into Venus. If it's lava is not molten enough, it's also very expensive to find radioactive containing silicates and dump it into Venus.(It may be that simply Venus does not have the perfect size for a lava, not enough insulation to get the core hot enough, even if it has the same average concentration of radioactive trace elements as Earth, or the Moon, or Jupiter.) If push comes to shove, it's possible to put up superconducting magnets by the Lagrange point to deflect off some of the solar wind. But a cold average temperature of the planet is a must before water and oxygen and nitrogen get retained in large quantities, especially water.

Some people are so fed up with "discrimination" that they will shortsightedly drive entire businesses out of business by trying to fix "discrimination" issues. And then how do you gain from the whole thing? At least you used to get tax revenue to your own area from these "discriminatory" punks that used to work there, once the place goes out of business, then there is nothing. Nothing.

    One neat thing in polymer science lately is what every other idiot spends his free time poking at, it's a smartphone, driven by OLED's, organic LED's, but that's like not even polymer science at its core, but organic chemistry optoelectronics, and may have more in common with pharmaceutical science than polymer science.

    Dense atmosphere and low gravity is nonsense, unless you have very high molecular weight materials, which tend to boil at higher temperatures, such as sulfuric acid on Earth sized Venus at 10 bar and very high temperature. But as far as we know almost all life on Earth directly connected to the atmosphere is photosynthetic origin as it's energy core (with the exception of deep ocean volcanic eruption sulfur chemistry cycle based lifeforms), so you'd assume low molecular weight oxygen in the atmosphere, to support carbon combustion of aerobic lifeforms, and therefore not that much density of atmosphere. Earth might be on the lowest possible gravity side of possibilities for life, as Mars has a very thin atmosphere, because of both low gravity but also because of lack of magnetic field/lack of solar wind shield. So you can't really have a life connected to an atmosphere in its function on a planet the size of our Moon, because there is no atmosphere at all on such sized a thing, because of insufficient gravity to hold one. So elephants on Earth might be the largest possible land based life forms in the entire Universe, but there might be a whole lot of places with say double or triple maybe 5x the gravity on Earth, and then most likely the largest lifeforms are bug-sized, with huge leg muscles compared to total body weight. If the gravity is too high, then we run into situations like Jupiter and Saturn and Uranus, that are full of captured gaseous hydrogen, as hydrogen is the most abundant element in interstellar and interplanetary space, and the only reason why Earth is not full of gaseous hydrogen is because it does not have sufficient gravity to retain it in the atmosphere at its escape-velocity escape region temperature. So if life is possible on these gas-giants in our solar system, then there are a lot of possibilities out there, but most likely life is only possible within a limited gravity range, Earth being on the lower end as Mars and Luna can't really support life (i.e. can't hold low pressure unboiled unvented to outers space liquid water to dissolve carbon based organic chemicals in essential for life), and on the gas giant high end you have issues with atmospheric hydrogen coexisting with oxygen during a lightning flash, and the whole atmosphere exploding - even if life is possible in/on gas giants, it cannot be carbon dioxide/oxygen photosynthetic/oxygen combusting hydrocarbon based, because of hydrogen explosions, but deep ocean hydrothermal vent type lifeforms might be possible, all you need is a sufficient driving force, high enough head for a local caloric waterfall.

    I used to ride a bicycle, about 40 minutes one way commute to work, slightly uphill, and the worst part was lack of fenders, and the whole road wetness spraying into my face during each rain. I could literally taste the road each time. I also had a rainproof set of clothes/boots, but my face was uncovered. Then I upgraded my bicycle to one with fenders. What a difference when it rained! But I can no longer get minimum wage jobs anywhere close, so my bicycle has been down for like 7 years now. But one day, when the price of gas hits $20/gal(not counting inflation), it's gonna be useful.

    Or more like patent collector fanatix. Seriously, polymer reasearch happened in 1890-1990. I have yet to see much new since. How about nanotubes! Yay! Or nano this nano that. It's a miracle! Like my nano-dick! Stronger than bone. Seriously, I was disappointed when reading the word "bone." I was expecting something like stronger than Kevlar.

    I've been thinking about modding the car, it comes as a 5-speed, and 3000 rpm in the 5th speed is like 80 mph. It needs to be a 6 speed of 7 speed. It would be nice to get 2000 rpm at 80 mph, or 1400 at 60 - it would really cut down the high rpm engine friction, let you maintain constant speed and not be a jerk, but it would not cut out gear friction, which is not that big of a deal. But tire rolling resistance is the major loss when coasting, and it depends on the air pressure in the tires, and too much of it is a tire bursting safety issue, plus wet traction issue, so I haven't been playing with optimizing tire pressure yet. If I had the dough I'd buy silica tires.
