Ammonia is about eight times as dense!

If that's the case, and it can easily be converted to a form of hydrogen digestible by the spaceship power plant, the hyperspace drives, and/or the fusion rockets, time for Traveller 2.0.

I liked the miniatures from attack vector (a space tabletop game with full 3d realistic movement). They have a Traveller variant.

Being a mostly hard scifi game, their view was that in vacuum you can only dissipate heat via radiation, so their reactors were covered in heat sink vents. It's the big spiky ball at the right hand end of the ship, separated from the ship itself by a metal cantilever (ladder?) frame. Those particular ones are space russians. Also visible at the other end of the ladder are the fuel tanks. In front of that is a cyclinder for the ship proper, covered in gun turrets of course.

I wonder if spinning them like a ventilator would help.

not in vacuum you can't spin like a ventilator for increased cooling

But attack vector ships can rotate freely independent of direction on of travel so you kind of boost past someone while pivoting to keep your batteries bearing.

As it's full 3d with up and down, it needs some effort to play, but it is well worth it if you want 3d movement that conforms to Newton's laws.

Or, you pump heated water vapour in front of the nose, let it fountain out, and have a scoop in the rear to collect it.

Rinse and repeat.

Spaceships: Accomodations and Is Artificial Gravity Really Achievable? | Answers With Joe

Rotating habitats and artificial gravity are a staple of science fiction movies and TV shows, but the realities of space travel means that someday we'll have to get serious about artificial gravity to keep our astronauts and space travelers healthy. The question is, what's the best way to do that, and is it even possible with today's technology?

https://www.youtube.com/watch?v=wYDJ0vxg1lU



1. Ideal planetary environment for human existence.

2. Micro gravity, circulatory system, and bone atrophy.

3. Coriolis force.

4. Monogee constant acceleration: fifty percent hull discount.

First-class flyers also have access to a self-service drink and snack station— not a typical offering on domestic flights, let alone a regional jet.

It was a sleek little nook at the front of the plane and I can see it being a favorite for passengers.

Despite being a larger plane, there is only one tiny lavatory at the very back.

Starships: Electronics and I Built a COMPUTER in Magic: The Gathering

Magic: The Gathering is famously complicated, but did you know it is complicated enough to make a computer inside of? Witness a world first in this week’s episode!

Thanks for watching, Super Nerds! I know this one is a bit dense, but being the MTG nerd that I am, I wanted to try an experiment. And below is the full set-up of the deck and a link to the paper if you're interested (it's very complicated!): https://arxiv.org/abs/1904.09828 and if you like Magic and/or EDH, please subscribe to The Command Zone, the only magic podcast I listen to: https://www.youtube.com/channel/UCLsiaN ... P7ewbJ0ecQ -- kH

1) Go infinite. Play Staff of Domination, draw whole deck.

2) Play Fathom Feeder, Reito Lantern, Lotus petal, demonstrate loop where cast—sac—lantern—fathom feeder to exile rest of Josh’s library.

3) Play Karn, exile card from Josh’s hand. Demonstrate loop with Capsize to exile all cards from Josh’s hand and all permanents he controls.

4) Cast Infest, in response Cleansing Beam (fathom feeder), Coalition Victory, Soul Snuffers, Gix

a. Give cloaks to 36 XN and RR.

9) Using Riptide Replicator and Capsize, create 36 creature tokens of varying power and toughness, using 18 different creature types we are going to use as symbols in our program.

10) Using Prismatic Lace, Glamerdye, Artificial Evolution and the Djinn, change text, creature type, and color of pretty much all my permanents.
a. All XN + RR going to be red, black, green, and white, and are going to make different creature tokens of a different color, according to our program.
b. All tape tokens to the left of the 2/2 orc are going to be green, all to the left will be white.
c. Our Fungus is going to be white and give counter to “incarnations” instead of slivers
d. Dread of night is going to look for “black” creatures instead of white.
e. Olivia Voldaren to make Assembly Workers instead of Vampires

11) Cast Donate 41 times. Give Josh all the hacked RR and XN, the Wild Evocation, a copy of the Vigor and the Archon.

12) Cast Illusory Gains on your White 3/3 Faerie.

13) Hacked Olivia Voldaren to hack all creatures in play as type Assembly Worker

14) Cast Recycle

15) Reito Lantern all graveyard specific order, Staff of Domination draw Donate, Donate + Djinn to Recycle and Privileged Position, draw 2
a.ON THE STACK, cast Reality Ripple on 18 of the XN and RR according to our program, gives the computer 2 different phases as your turn comes around

16) Reito Infest, Cleansing Beam, Coalition Victory, Soul Snuffers to library, draw rest of library + Infest

17) Karn / Capsize exile my hand plus all set-up permanents

18) Cast Karn, exile card from my hand, in response, Capsize Karn

19) Cast Wheel of Sun and Moon, cast Steely Resolve (naming Assembly Worker)

20) PASS

To be fair, you probably wouldn't survive the EMP generation event and you're a vital component of this computer. :-)

By the way, this computer using magic cards is a digital computer, meaning that it has discrete or distinct states, vs a continually-variable system like a slide rule or sundial, which is an analogue computer.

I know of no universal law of computing that defines the limits of an analogue system - unlike digital systems which have their limits defined by Church & Turing's work. While it's true that all turing machines can in theory emulate each other (assuming unlimited memory), it would take an awful lot of magic cards and time to compete with a laptop. But fundamentally it is true; the magic cards and the laptop both have the same theoretical limit on their ability to compute. (Edit: or more importantly, if there is something one cannot do due to Turing’s limits, then the other cannot do it either)

Spaceships: Engineering and Why Plane Tires Don't Explode On Landing

Plane tires need to support thousands of pounds of weight at high speeds, so why don't they pop? We talked to Goodyear, one of the leading manufacturers of plane tires, who told us why.

https://www.youtube.com/watch?v=_CyXMNHYl70



Do our spaceships use tyres?

If you're thinking skids for vertical take off, or telescoping legs, tyres will allow taxiing of the spacecraft without turning on the reactor.

Spaceships: Accomodations and Dreamliner oxygen may not work by NICK FARRELL

In the unlikely advent of a cabin depression, you people sitting there, there and there, might choke to death

A Boeing whistleblower claims that the good people at Boeing may have made another short-cut on one of their designs of the 787 Dreamliner that leaves their passengers without oxygen if there is a cabin depressurisation.

John Barnett claimed that a quarter of the oxygen systems could be faulty and might not work when needed. Faulty parts were deliberately fitted to planes on the production line at one Boeing factory.

Boeing denies his accusations and says all its aircraft are built to the highest levels of safety and quality.

However, this is the same firm which signed off on the safety of another one of its planes, the 737 Max only to see them drop out of the sky twice.

Barnett, a former quality control engineer, worked for Boeing for 32 years, until his retirement on health grounds in March 2017. From 2010 he was employed as a quality manager at Boeing's factory in North Charleston, South Carolina.

This plant is one of two that are involved in building the 787 Dreamliner which has proved a hit with airlines, and a useful source of profits for the company. So far though none of them have been forced to deploy their oxygen masks.

Barnett said the rush to get new aircraft off the production line meant that the assembly process was rushed and safety was compromised. The company denies this and insists that "safety, quality and integrity are at the core of Boeing's values".

He told the BBC that in 2016, he uncovered problems with emergency oxygen systems. Without such systems, the occupants of a plane would rapidly be incapacitated. At 35,000ft, (10,600m) they would be unconscious in less than a minute. At 40,000ft, it could happen within 20 seconds. Brain damage and death would follow.

Barnett says that when he was decommissioning systems which had suffered minor cosmetic damage, he found that some of the oxygen bottles were not discharging when they were meant to. He subsequently arranged for a controlled test to be carried out by Boeing's own research and development unit.

This test, which used oxygen systems that were "straight out of stock" and undamaged, was designed to mimic the way in which they would be deployed aboard an aircraft, using exactly the same electric current as a trigger. He says 300 systems were tested - and 75 of them did not deploy properly, a failure rate of 25 percent.

However, his attempts to have the matter looked at further were stonewalled by Boeing managers. In 2017, he complained to the US regulator, the FAA, that no action had been taken to address the problem. The FAA said it could not substantiate that claim because Boeing had told them it was working on the issue. Nice that a regulator took Boeing's word for it.

Boeing concedes that in 2017 it "identified some oxygen bottles received from the supplier that were not deploying properly. We removed those bottles from production so that no defective bottles were placed on airplanes, and we addressed the matter with our supplier".

1. Twenty five percent possible failure rate, in an emergency.

2. Paranoid passengers might want to carry onboard a supply of their own.

"Faulty parts were deliberately fitted to planes on the production line at one Boeing factory.".... what did you expect? Surely one cannot just throw away such expensive components! :p

Spaceships: Engineering and What are Hypergolic Rocket Fuels? (Other than Explosive, Corrosive, Toxic, Carcinogenic and Orange)

Hypergolic fuels are a core technology in rocket science, propellents that will spontaneously combust when mixed together. This makes them attractive for rocket designers, who generally aren't the people who have to get in a the protective gear to load the stuff.
So, what are they made of, and why do designers pick one option over another?

https://www.youtube.com/watch?v=AFLmqQ5ceS8



So what exactly are our reactionary rockets using as fuel?

Hypergolic? They are just making word up now. 😀

So do we get this before we get binary propellant guns, or after?
