  1. While the natural carbon/hydrocarbons cover their cost, nobody will kill the cow which gives milk. When they will begin deplete, first "green alternative sources" will be (already are) rising - "instead of dirty nukes". Because it's a profitable good for sell, too — why not to sell it? This will also change the energetical infrastructure into "pure electricity" way. When low-cost carbons/hydrocarbons indeed will be over, the Almighty Atom will rise. And this — already up — "green energy & pure electricity" infrastructure (lines, feeders and charging plants) will be powered with nuke reactors. 2 bln of petroleum cars (I even didn't know about that) are a gift of gods for industry. Imagine: you can produce and sell 2 bln electric cars instead.
  2. Electrolysis requires energy. Much energy. Which is currently produced by burning the coal. Anyway, from an external powerful energy source. Creating methane from carbon you just store a part of external energy as an energy of chemical bounds. So, it's by definition an endothermic process. Charcoal is just a carbon part of dry plants. See above about flowers vs algae. Liquids mostly cannot be compressed. Solids get crushed when being compressed. So, they both get heated only by the energy waste value. Gases can heat on compression just because there are huge distances between their atoms. Solids and liquids are already packed.
  3. If they can live on Venus, they can live anywhere. Any place is better than Venus.
  4. A classic question: "How many bits in 'E=mc2' ?"
  5. Somebody should bring the embryos to life and grow them up. Another thing with embryos: even if they magically born as adults, they hardly would associate themselves with Humanity. So, Plan A+B: an intentionally degraded tribe believing that they are Night Watch Crew. 200 years later the Computer explains them that they are the Chosen, they grow up the embryo-born babies and assist them while hologram coaches teach the children. So, the tribe is happy for their Mission, the children count themselves as Humanity, all are happy.
  6. Type A. Refrigerators, refrigerators, refrigerators... Reactor. Alarm clock. Type B. Intentionally degraded tribe. Reactor. Alarm clock.
  7. Starflight: The Plane That Couldn't Land The Last Days On Mars Red Planet
  8. Looks like their war will be a reproductive competition... If even on Venus...
  9. And as a result you get a heavy rotating dumbbell, threaded onto a long slender axis — trembling like a chord — and give the ship a name: "Precession". While using Endurance style ship your opponent gets a ship "Doughnut of Chaos". As desired:
  10. According to a book bout the meteor observations: -2.5 lgE = m + 14.2; I = Ed2 = 0.5 mv3 cos zR; Which gives us: E = 10-0.4 (m + 14.2); Ed2 = 0.5 mv3 cos zR; d2 * 10-0.4 (m + 14.2) = 0.5 mv3 cos zR; mv3 = d2 * 10-0.4 (m + 14.2) / (0.5 * cos zR); mv3 = d2 * 10-0.4 (m + 14.2) / 0.5 = 2 d2 * 10-0.4 m - 5.68 = 2 d2 / 100.4 m + 5.68; mv3 ~= 2 d2 / 100.4 m + 5.68; where: m — mass of the meteor, g; v — velocity, km/s; d — distance from it, m; m — brightness. So, to get, say, brightness = 0 (as a bright star), from d = 50000 m: v = 40 km/s → mrequired = 0.16 g v = 7.9 km/s → mrequired = 21 g
  11. Of course. Why should they trifle? It will be assembled in the space. Fuel (D+He3) — probably captured from upper Jupiter atmosphere. As always. Blueprints
  12. Not long. Not a plane. Hab of tanks. All directions. Daedalus
  13. P.S. By adding a long tail with nukes can be easily converted into Discovery. P.P.S. The topic starter should first define: whether he means a ship with landing capabilities or no.
  14. Looks unlikely if the turtles could have name, as they can't react on them and can be poorly perceived as individuals. As also flour beetles or drosophila flying together with them. A search in Russian brings no info about it: just "two Central Asian turtles". Maybe vivarium technicians called them somehow, but most probably they were just Next Shrub Turtles "random_turtle_1" and "random_turtle_2". Also "Bek & Lek" pair sounds strange in Russian (like a pair of Polish names), If they have names, there could be "Tortilla" (a common turtle name from a book) or "Vasya & Fedya" (just two common human names). P.S. There were Polish animated cartoons, popular in the USSR with two main characters: Bolek & Ljolek. (1960s and later) Maybe somebody somewhere called this pair of turtles so — but not like personal names, just as a joke.
  15. Btw, in KSP turbojets also use LiquidFuel, with IntakeAir (presumably, oxygen). Not sure if turbojets can use hyperholics. At least, pure ones. LiquidFuel: density = 0.005. unitCost = 0.8, hsp = 2010 Oxidizer: density = 0.005, unitCost = 0.18, hsp = 1551 MonoPropellant: density = 0.004, unitCost = 1.2, hsp = 3000 Water (in CRP): density = 0.001, hsp = 4183 // specific heat capacity (kJ/tonne-K as units) LV-T30 ratio: LiquidFuel = 0.9, Oxidizer = 1.1 I.e. their density is 5 times greater than water, ~5000 kg/m3. and fuel:oxidizer ratio ~1:1.
  16. Just found a nice page. (This unlikely could be official.) http://richspacetech.blogspot.ru/2013_09_01_archive.html
  17. From the "energetical" plantation. The more energy is misused by the plants, the greater area you need to occupy with this plantation, the longer way for a tractor, the longer pipes for water, etc. Every joule spent into a branch means several joules lost to grow this branch. Bingo! A thin layer of algae - never. Its underwater. No, they just are non-ideal. A leaf is not a solid plate, it is a pattern, its weak parts are transparent and can't catch all sunlight falling onto them. The more homogeneous is the layer - the more energy it catches at its very top, the less biomass is required per area. Total area of those windbreaks in ridiculous comparing to total area of the cornfield. Ten more tonnes of straw and brushwood are not a solution. Thanks. Camping places have anything they need, including electricity, gas, wood, but their total consumption is miserable comparing to the regular need in energy.
