  1. O After seeing that pic I have decided to scrap the idea. Visuals do wonders. Yet the main reason is cause the human body has far too many nooks and crannies that only fingers can reach and attend to properly as far as hygeine goes. I am not going to get graphic but I think you understand.
  2. Not handeling AM waste heat is my primary issue. By the time we have enough mass in heat rejection equipment such as heatsinks and big rad fins, it will lower the awesome thrust we were supposed to have anyway. On the other hand, the external combustion engine AKA Orion project has less of of an issue there.
  3. No real need for a humanoid to have multiple hearts unless a spare backup. The octopus has multiple hearts doing separate duties that our one heart does combined all by itself. It is not as if one of the octopuses heart's fails it can still function.
  4. No need for two hearts and a regenerating brain. Two hearts only offers an advantage if not connected, so the other can be used as backup, otherwise they both clog up at the same rate more or less.
  5. More or less true it seems. Wikipedia indicated we could make a pure fusion bomb similar in yield to a conventional explosive, the main problem being that it is more complex bur not more destructive beyond radiating the area.
  6. Oh yes it has bones and muscles, looks human, just the skin and hair are colors humans don't have. As for the suction plates, good idea. If mini enough, they could be used to manipulate small items much like fingers, even delicate stuff like tweezers. Octopus suckers are very flexible, and the alien ones could be smaller with the added feature of full 360 rotation for ALL suckers, being able to choose selectively which ones and how, besides the sucker pinching that octopuses already have IRL. This allows for them to use the suckers to rotate an item on their palm or even stand it upright, all without using their thumb. Good ideas! You helped salvage an idea I was gonna regretfully scrap. Now with these mods the mitt can at leasr compete with the human hand, besides beibg superior for climbing walls (greater surfae area/suction/adhesive fluid optional). The main problem will be flossing their teeth. It would be a proper nightmare. Unless they all have bad breath due to not flossing, or perhaps their mouth and tooth bones are nore acid resistant and regrow their whole lifetime if broken? Perhaps they just swish acid in their mouth and spit to clean between the teeth? Perhaps the feature comes in built, which means yes they can spit acid if they want, used primarily forcleaning hard to reach places in the mouth.
  7. Unlikely. The weight budget added would offset the benefits it seems by loweribg overall thrust dramatically.
  8. Um... machines are inferior to us in one respect. A total lack of intution and adaptability. They are to do one job and do it well, whereas we are not made to do anyspecificjob per se, but can learn to do just about anything. We trade efficiency for adaptability. And machines make poor judgement calls. They literally would not know what to do in an ethical situation they were not programmed for.
  9. "Not chess. Poker." -Captain Kirk TOS It got me thinking, what would a game be like that combined features from both chess and poker? The greatest game ever? Chess is anything but random with total infornation right in front of you, whereas poker involves bluffing since there is plenty of information you do not know. The best I could think up is perhaps this: Only difference is make it a chess board and make the chess pieces like to stratego in that your opponent cannot see what piece they truly are. I know piecr movement is a dead give away, but it still allows for plenty of bluffing. Making it a game humans could consistently do better at than machines. What do you think? Any ideas of mixing chess and poker you may have? Or improve upon what I started perhaps?
  10. According to wikipedia having some antimatter could initiate a pure fusion bomb, including the small ones for project orion. Otherwise we are looking at a 3 ton big bomb to generate the power. Overall it is hard to make mini without a lot of compact energy ready to go (looking at AM again). https://en.m.wikipedia.org/wiki/Pure_fusion_weapon
  11. Fusion bombs are hard to make no? Not saying they are impossible, but you would think we would already have them if they were viable right now. Making them mini enough to use them for project Orion should take a higher level of tech than we currently utilize today. So scifi are pure fusion bombs.... for now.
  12. So I could just make the ecosystem fit them more. Bigger seeds, etc. Just about about everything changes compared to our world. Even so, they could still pick up tiny items with the suction plates, but manipulation of small stuff or tools will be far more tedious for them than us I agree... so I may have to just dismiss the idea and just go with the suction cup ped palm and fingers.
  13. True... it's just that every other powerful thing O knowof on par or betterthan a nuke in nature also is highly radioactive. So AM is a key to orbital infrastucture if we had plenty available like in scifi
  14. The mini orion tests are a series of explosions.
  15. I will level with you. Truth is, I have mutiple scifi races in the works, and claws are already featured on one, so oven mity shaped hanfs with suckers is likely the most imaginitive shape I have devised so far. As morr than one of other races are partly animal inspired.
  16. Do you not think AM will provide a bigger boom? Or do you not think the designers cannot do the math to make the boom not so big that the ship dies?
  17. Really? Any proof? I really want to know. Never heard that b4 but it sounds plausible. AM would make a more efficient Orion. Bigger starfleet that way.
  18. Given what we know of physics, if we had a lot of antimatter to spare and could launch ten orion pusher plate battleships to orbit a year, would the air still be safe? Better than if we did the nuclear fallout version? Since AM bombs I read don't pollute as bad as nukes even though they are far more destructive. Which is a parodox if I have ever heard one one. Discuss?
  19. Magnetic fields eh? I only wish this happened, but the current state of affairs and physics would make it nigh impossible. Gravity is tough. For being the supposedly the weakest of the four fundamental forces it is more influential and more obvious than most. https://m.youtube.com/watch?v=FLujoeWx0RE
  20. I see. So even if we had a form of propulsion without propellant the question becomes what kind of reactor is providing you power and how efficient is it? Taking a modern example... A nuclear sub. Using nuclear reactor to power a vacuum reaction drive. Absurd I know, but it is just an example of the concept. Nuclear subs do not have the greatedt TWR, even if they had no water to run against and used space instead. Could not even make orbit. Antimatter reactors maybe work with OP drive.
  21. Interesting. Space don't have a lot of concetrated EM fields without a source of mass. Space has a lot of EM waves (radiation), but I am not sure that can be converted into momentum without a lot of focusing mirrors and large sails plus a lot of time. So whatever ship could pull off the OP without infrastructure would be freakishly powerful.
  22. I ask because if there is or if there was, it would beat the whole tyranny of the rocket equation? If there is no conceivable way you can think of in physics that's fine. Just wondering if there is a possible way... and if not, it will be purely scifi wish fulfillment. Even if there was a way I am betting the drive would have a speed limit based on overheating. Since for every action there is a reaction, and if the drive is reacting off space itself... Discuss?
  23. In the case of the oven mitt shaped hands, they would indeed have bones within them, allowing for flexing movements similar to what a human would make with an oven mitt. But even though they hamper the humanoids in many ways, it won't stop them. As for wear and tear, octopuses are known to shed sucker plates with high use, with a fresh one replacing it underneath. So I suppose getting shed suction cups detached from stuff throughoutthe workplace will be a clean up your own mess kind of deal or coworkers start giving the person the look.
  24. I cannot say the idea is not interesting. because I would be lying, but snotweb sounds... gross. But that is besides the point. In a way, it is quite practical, assuming one wanted to make clothing from it. Just eat several cartons of eggs and wait a few hours for digestiom. Then blow and spray the nose while looking down at chest. Such a garment would need to be draped around to cover the back, and some stickiness could pay off here. So the end result is everybody wearing spidersilk catsuits, sometimes colored with pigment dyes for style. Gross? To humans yeah, but effective. Without eating enougheggs I suppose the nose would just get normal boogers. I also presume that they do not use the initial few strands of web, as they have boogers on them. The ones after are clean.
  25. Being a writer makes me privy to knowing about a lot of seemingly unrelated information... at first glance anyway. Snot webs? While possible anatomically, it would incur a far greater cost than a tiny spider would, due to body mass. I saw a website once that calculated for spiderman to make enough webbing to perform even ONE of his many feats in the early 2000's superhero movies he would need to a LOT of eggs. Let’s assume Spider-Man produces silk that has the same characteristics as dragline silk produced by the European garden spider Araneus diadematus. That means it ought to have tensile strength – which is the largest stress that a material can withstand before breaking – similar to that of a piano wire. A piano wire has the tensile strength of 1.1 billion Pascals. Pascals is a unit of measure for pressure, which is force per unit area. According to Marvel’s directory, Spider-Man weighs 75kg. Applying Newton’s first law, we can figure out the downward force that Spider-Man exerts. It would be mass times the Earth’s gravitational acceleration, which works out to be about 735 Newtons. These two values allow us to calculate the cross-sectional area of spider silk by dividing the force exerted by the tensile strength of the silk. Without going into the tiny calculations, it turns out that Spider-Man could hang from the ceiling on silk that is less than 1mm thick. Now we need to figure out how much volume this total silk fibre would represent, if Spider-Man’s pre-lunch world-saving session requires 100m of it. Silk is slight heavier than water, which means that 100m of the wire would weight about 87g. There is about 6g of protein in an egg. So it looks like Spidey only needs about 15 eggs for breakfast if he plans to use 100m of silk. That’s not too bad. More eggs please. tonymadrid But spider silk consists predominantly of a protein call fibroin. Proteins are made from different amino acids, and fibroin is about 42% glycine. While egg consists of just 10.7% glycine and serine (I’m counting serine because it can be easily converted to glycine). So really Spidey needs to consume four times more egg protein than the silk protein he plans to use. So actually he needs 60 eggs for his 100m of silk. That’s not really the end of it either. After all what happens if he leaps from a building to save a falling Mary-Jane and deploys his webslingers to save the day, as he does about halfway through the movie. In the scene, Spidey leaps from the balcony and falls for seven seconds before his silk starts to arrest his fall. He has caught M-J so let’s say their combined weight is 125kg. How much silk is he going to need here? From the time of Spidey’s fall, we can calculate that he fell about 240m (wow, that’s one high balcony). Plus, assuming the silk stretches to its maximum, a stopping distance, it will be a fall of about the height of the Eiffel Tower. The impact force on the silk rope as they slow down would be about 35 times their weight. Which is about six times greater force than when Spidey is just hanging around on the end of his line of silk. But taking into account the length of the fall (240m) and the extra force, he will need 1.3 kg of silk to catch his fall. So I reckon he must have had about 900 eggs for breakfast that morning, just to have enough silk for that one scene. I think Aunt May might have noticed. Comment on this article
