  1. as said Joker, diving in the tank of the chemical one.
  2. There are many things able to be washed and reused, though this usually doesn't make sense. Nobody has seen clear numbers of the reusability sustainability, so it's just a question of belief to the moment. To learn the possibility doesn't mean to use it in business, it's a skill.
  3. They are going to spend ISP on construction rather than acceleration, because the dusticles (ceramicles?) don't fly themselves, they eat the exhaust speed. Packing the concrete with a blowtorch. Possible, but why?
  4. When a launch fails, such artifact remains.
  5. Idk, just quoted. Maybe it's well-lubricated and slips through the air. Or maybe it's so fast that the sound gets lost far behind and decides to not follow.
  6. https://www-interfax-ru.translate.goog/world/796821?_x_tr_sl=ru&_x_tr_tl=en&_x_tr_hl=ru&_x_tr_pto=nui They have tested a soundless 100 km-range artillery shell. Who wins: an airborne laser or a soundless long-range artillery shell?
  7. The rainfall is caused by toxic chemicals (heavy metals like silver, halogenides, etc) and affects the local bioequilibrium. So, the artificial mass raining will make the plowlands dangerous and the food chains broken. Also, if take a look at the globe, between 25N and 25S (so, actually, to the South from 25 N) every land which is not flooded by water and covered by jungles, quickly turns into a desert, so the agriculture requires a lot of industrial efforts there. So, the raining may help in local places, but not widely. And that's exactly where the countries of median age < 30 are placed.
  8. Exactly so. This week. Not "my", but the one I was watching for several years, the Outpost. But anyway... *** Fantasy is a fiction for those who sucks in technics, but also never tried to live and work in a real countryside.
  9. A pigpigeon. Flying around and bombing the statues. Doggerine (do not confuse with the wolverine)
  10. https://en.wikipedia.org/wiki/List_of_countries_by_median_age Order the tables by the median age columns, watch the geography, and remember that everyone below 30 will likely give at least one child within a decade or two. The "median age" is the age where a half of the population is younger, another one is older. Can they keep doubling the water sources every 10..20 years, when the existing ones are "90%" depleted? The water desalination requires energy and plastic, i.e. carbon dioxide production. So, the water crysis will chase much earlier than the carbon one.
  11. Wouldn't thou, please, be so kind to shalt drop no crumbles on the floor, please? Thank thou in advance.
  12. It looks like the troubles with low fresh dihydrogen monoxide will chase the biosphere long before the problems with excess of the carbon dioxide. And unlike the doubtful human role in the latter, the former is exactly by humans, and nothing can be done to it except preparing for the future biosphere reconstruction.
  13. Maybe someone can read Kerbal rap in reversed language? *** By default - in reversed Spanish, but as Chatterer demonstrates, any other language is enough good, too. Audacity, record, then Select All, Effects / Change Speed +33%, Effects / Reverse.
  14. If flow with the river enough long, a body of your enemy on the coast will pass by.
  15. When you can ideally synchronize the ships movement, at the same time turning their velocity vectors , to keep the tether tightened. Even the modern ship have to wait several minutes after dockng to let the oscillations stop. And a kilometer-long tethered system of thousand tonnes would be a yo-yo.
  16. Use the zero-based absolute scale. The span is +/- 20 K, the average is 233 K. So, the relative variation (sorry for incorrent English terms) ~8.5%, and gets ~2% since 10 kya. Compare to the Sun luminosity variation. It's tenths of percent or so. So, the natural factors are significant.
  17. If they keep the tether tightened while getting away, this means that they need to accelerate perpendicularly to the thether, keeping it tightened, and having the tether gently expanding/retracting for that. If it's weakened, they will get a radial shock when it gets toghtened. This means they need a motor comparable to the sudden shock acceleration, i.e. comparable to the average 1 g, and still keep perfectly synchronize the ships at 1 km distance. And the halfships are hubdreds tonnes heavy at least. So, this is a thought-out scheme for ideal conditions never tested even on lesser crafts. (Although Voskhod-6 was planned to do it, it was never sent.) And anyway the shock will cause a wave of stress in the tether, as the tether is elastic. So, even once they have started rotating, they will need some time to let the oscillations in the tether shade out and dissipate the mechanical energy in the tether winches. This means that they will withstand a sequence of shocks in the winches before the tether stops elastically expanding/retracting and gets the fixed length. This series of shocks should be put out by a spring or so. As the ships are too big for springs, this means that they should use magnetic springs, i.e. the winch should be equipped with electric motor enough capable to hold a series of ~ 1 g shocks.
  18. Only deterministic events can be delayed. Others can't.
  19. Although both Croatian and Russian are Slavic, I wouldn't understand what's the "chamfer" are they talking about, before having a look and and realising that it's a фаска /faska/ /fus-kuh/.
  20. The transition between the linear movement before and perpemdicular 1 g pull after is.
