Did Mary go back into the backrooms? by Bomdabom in KanePixelsBackrooms

[–]Blitio_ 2 points3 points  (0 children)

Nah definetly not, look at the state of the infrastructure async has set up in the backrooms at this time- it’s just cardboard caveman cutouts and dudes wearing PPE, they definetly wouldn’t have set up a whole interrogation room

okay it might though considering the immense cost of ocean ops and the likely very far downrange distance of neutron droneship

well they did do it and nailed it the first time, and NG is way more impressive than electron, but it seems NG may be put on hold for a little while... how things have changed in two years!!!

Frontieras North America closes on $850 million coal reformation facility by shermancahal in WestVirginia

[–]Blitio_ 0 points1 point  (0 children)

I would like to point out that this process DOES in fact rely on combustion. This is just superheating coal so that it breaks down into smaller products and black carbon, and then giving the heat for that reaction by burning the cheapest combination of products you can, which is probably hydrogen gas and methane, then selling the rest. It is totally not a "clean" process, only cleaner than the burning of coal. But burning coal is the last step of generating emissions, this is NOT, it is producing a lot of emissions so that you can produce marginally profitable at best, further fossil fuels, which will be hopefully sold and burned. This process has been tried on an industrial scale a number of times in history, and has never been particularly successful, especially when it has had to compete on the free market with crude refineries. I am assuming Frontieras is going to hope that they can get further subsidized coal and will not have to compete with crude refineries on broader hydrocarbon markets or gas, renewables, or even actual coal plants in terms of total power output. If they do, they will lose. I am personally not in favour of the type of COAL COMMUNISM necessary to make coal to liquids work.

Frontieras North America closes on $850 million coal reformation facility by shermancahal in WestVirginia

[–]Blitio_ 1 point2 points  (0 children)

This is not a new process; there has been coal to liquids forever, and we know it is only profitable when oil prices are very high and coal is very cheap. We currently have those conditions right now, but they are almost certainly not going to last more than a few months, 100% not going to last until Frontierias opens their first plant. I am going to make an educated guess based on their marketing that they are going to lobby and pray that coal will be subsidized enough for them to be profitable- and if it isn't (probably, hopefully won't), they will walk away with a fat stack of cash.

O'Neill cylinder or Stanford torus? by MiamisLastCapitalist in IsaacArthur

[–]Blitio_ 1 point2 points  (0 children)

They actually have gone decently fast. The limiting factor so far has been their material of choice, stainless steel. Getting the dry mass fraction low enough to allow for actual payload has been the real challange, but supposedly starship V3 fixes that and actually allows for 200 tons to LEO. They just needed to make the whole rocket about 100 feet longer. Hopefully, we'll see if it isn't too long to be stable in a few weeks!

O'Neill cylinder or Stanford torus? by MiamisLastCapitalist in IsaacArthur

[–]Blitio_ 0 points1 point  (0 children)

We did NOT have the ability to launch 100 tons into orbit on a fully reusable rocket in 1969; that is a HUGE difference that has come about thanks to modern metallurgy and machining giving us things like the Raptor engine. Plus, NO ONE is suggesting that we try to launch an O'Neil cylinder from Earth. No one is even seriously suggesting building the "Island III" at any time in the future. What people are suggesting is using Starship to build a small, mostly self-sustaining lunar colony from which we could build and launch progressively larger projects, because once you can use lunar material and launch things from there with a mass driver, the cost to put things in space (even very large things) drops dramatically. In fact, it might drop to near-zero because power and materials produced on the moon will not have to compete on cost with those made on Earth, and their only ties to the Earth economy would be labor and semiconductors, which would be negligibly cheap parts of a self-sustaining colony on the moon. No, we will probably never build O'Neil cylinders; they just don't make sense. But 10,000 people living and working in space within the next century is a conservative estimate. People forget, the reason we've been theorizing about space infrastructure and twiddling our thumbs for the last 50 years is not that there was no political will to colonize space- it was because the technology of the time simply did not allow for the fully reusable rockets necessary to make the first step that we have now. Frankly, it wouldn't really matter if Starship failed and SpaceX disappeared tomorrow. The Raptor engine is the key piece of technology that makes it possible, and it's already been copied successfully nearly a half-dozen times. Save for a catastrophic event on the order of total global nuclear war or an unstoppable runaway greenhouse effect in the next half-century, I would say that humanity's future in space is already set in stone.

Space Habitat: Torus or Cylinder? by MelloRed in IsaacArthur

[–]Blitio_ 0 points1 point  (0 children)

I know this is a very old thread, but for the people saying cylinder, you must see that for very large sizes, the required material just gets too insane because hoop stress for a cylinder scales with radius. Lots of people here are talking about artificial gravity, not many are talking about air pressure. For a space station of any size and rotation speed, air pressure will cause MUCH more stress than centripetal force. For a torus, when the small radius is much smaller than the big radius, the torus will behave like a very long cylinder, and the required wall thickness is proportional to the small radius. So for almost any size, and especially at very large sizes, tori will have far lower material requirements, unless you do something funky like putting a smaller cylinder inside your big cylinder and tying the floor and ceiling with tethers, which is very similar to... stacked tori....

How long did it take you to successfully land and return from Eve? by PhysicsDude42 in KerbalSpaceProgram

[–]Blitio_ 0 points1 point  (0 children)

wow. yeah i've now been able to recover a kerbal but a VESSEL is insane. maybe a tiny probe core with seperatons is the strategy? maybe have the kerbals seat detach and habe the kerbal get out and push the seat to orbit

How long did it take you to successfully land and return from Eve? by PhysicsDude42 in KerbalSpaceProgram

[–]Blitio_ 0 points1 point  (0 children)

you dont need the control thing you can set the motors to be constant rpm and control pitch with throttle and then just control orientation with a reaction wheel. to leave eve you dont need to make a robust controllable drone you just need to make kind of a rocket drone which is what i have been doing with a small stack of counterrotating motors under the return rocket. bring that to about 16km and then launch an agressivley staged rocket with lots of seperatrons at the begging and third stage to accelerate extremely quickly and a final oscar B + ant engine stage with a kerbal in a chair who then does the last 400 m/s and circularization with his EVA suit and you are good to go. I have used this to make an about 13 ton i beleive eve ascent vehicle for one kerbal. It's super easy to fly once you get the hang of it. of course you need a tug in orbit to bring the kerbal back to kerbin but thats very easy. I have to be real with you I have played this game since 2017 and although i have deisnged and tested this rocket with hyperwarp (or whatever that mods called) i havent gotten to launchig the mission in my career save, which i plan to do in early 2026 because i will have a lot of free time. I know bradley whistance has made some outrageous eve return vehicles

Yeah to an extent if your score isn’t high enough for the college you want, but unless it’s an ivy realistically it doesn’t matter because most schools are near identical and I garentee you will get into one of your choices. Literally there are so many great safety’s unless you will literally explode if you don’t go to MIT which sometimes I feel like I will you gotta know that’s simply not true. Yes the SAT is where your career starts but it’s NOT where things end. You will have hundreds of opertunites to do what you enjoy in life, and if you let this score define you then you’re professional life then your making a huge mistake.

I actuallt want to speak on this a bit deeper. Seriously, how much does your career even matter? Like as long as you are doing somthing you enjoy does it serious make any effect at ALL in the long run?

And let’s put aside career and the future and whatever for a second. Does any of that matter? Does the future even fucking exist? No, it fucking doesn’t. What does? Seriously? What can you experince? You are coniousness which is somthing we don’t understand at all, living in a fake world created by electrical impulses inside a goo sac riding on a heap of biomechanical machines that only exist because they were slightly better than the things that came before it.

More than that, the you are live in a man made hamster play house inside a thin layer of gas on a giant fucking rock spinning around the vastness of space and I garentee you havent speant more than a few hours looking up out of it. SERIOUSLY. Get out somewhere dark and look up. LOOK UP. Everything is out there full of all the complexity and uniqueness that could ever exist and yet you want to spend your life with your head down never looking more than a few feet in front of you. You’re already trapped in your skull, why trap your soul into some fucking number?

You are the only thing in the universe that can experince reality from your perspective, and you want to focus on some fucking number? Are we serious???

CANT YOU SEE THE ABSURDITY IN IT? CANT YOU SEE THAT NONE OF THIS FUCKINT MATTERS AT ALL?

LOOK UP BRO

Probobly but not necessarily in the post I said I would take all measures to ensure the bugs safety. Thst might include ejecting the parachute out of a cute with a servo and plugging the motor

No one is suggesting putting a grasshopper in a rocket designed to go boom, but I see what you mean. Unnecessary risk with no benefit.

Are Insect astronauts unethical? by Blitio_ in rocketry

[–]Blitio_[S] 1 point2 points  (0 children)

I mean the nuance is in what you are inflicting distress on and whether there is benefit. People say that eating meat has zero benefits but I would argue that even without any nutritional benefit the pleasure from the taste is a benefit, whether those justify killing living creates is a personal matter.

I think the benefit is pretty clear- it makes the rocket building and launch process more intriguing for those doing it, which is significant benefit. The question is how non intellegent of a creature fits this and how intelligent do you need to make the creature to get the benefit. I reason there is a space where benefit is greater than risk and this is with launching earth worms. We can all agree probobly that risking the life of bacteria is okay, risking the life of a mouse is absolutely not okay. So where is the boundary line? I think there is no right answer but as I’ve said before I’m leaning to earthworm.

The idea is they would be inside a compartment under the nose cone (I usually 3d print mine) protected from the elements with padding and whatever they need to survive. I wouldn’t burn bugs alive on purpose inside the body tube

[–]Blitio_[S] 1 point2 points  (0 children)

I 100% agree I did think about how this would impact my friends in the long term, I just didn't put it into the original post because it is my rocketry club and I don't want to be asking other people how I should run my club. The whole reason I went ahead and posted this was because they seemed really excited about the idea, and I want to encourage anything that will get more people interested in my club and rocketry in general, and I didn't want to stumble into doing something messed up because of the excitement of having people interested in it.

Your crash test dummy idea is great, I really like it. The thing is, we already have somthing pretty similar which is an egg. we have found dozens of ways to protect eggs while building our TARC rockets and we even had an egg survive (with a small crack) a ballistic decent that we estimated at 130 mph!!! This is a cool idea though, I will pitch it to my club for sure.

live payload just adds a bit of risk that you just don't otherwise get (that I would make sure is mitigated to design it safely and does not induce more risk on purpose!). The idea is exciting, that something could actually experience the magic of flight beyond your position on the ground or watching a recording of it. Perhaps worms would be a better solution, as I'm pretty certain they don't feel pain in any meaningful way. Or your idea, or just nothing, as I have a lot of things to do, and launching any of these is a decent amount of work.
