Drinking Coffee From a Cup In Space
muggs was one of several readers to note a fluffy piece making the rounds about an astronaut inventing a
zero-g coffee cup. Of course, since the space station inhabitants drink recycled urine, I'm still not totally convinced that I would want to try that cup.

'But it *is* piss, Buzz.' 'Oh good, so it's not just me.' Apologies to Austin Powers.
He used a piece of plastic ripped from his Flight Data File mission book and folded it into a teardrop-shape that's closed at one end. Surface tension inside the cup keeps the coffee from floating out and running amuck.
"The way this works is, the cross section of this cup looks like an airplane wing," he said. "The narrow angle here will wick the coffee up."
The result: space coffee in a zero-G cup.
The theory behind the novel coffee cup is the same one used by rockets to draw fuel into their engines while flying through weightless conditions in space, Pettit said.
They just drink pencils.

Imagine, a guy with the name muggs would have the inside scoop on this story.
Unless you import virgin hydrogen and oxygen from a supernova, the water you had this morning has been through several organisms...
And, ummm, who doesn't? Most of us just have a bigger recycling plant than they do.

I'm having a bit of trouble picturing this... is it like drinking out of an erlenmeyer flask?
No sig for the moment.

This is by far the coolest thing I have ever seen. I want one for my home and office. I can then drink coffee while hanging upside-down from the ceiling doing meditative reflexology. If Nirvana could exist within reach of this torrid mortal coil, this zero-g coffee mug has extended a very tempting invitation!

Of course, since the space station inhabitants drink recycled urine, I'm still not totally convinced that I would want to try that cup. And just what do you think that fresh spring water or tap water you're drinking is? There's been life on this planet for 3 billion years, every drop of water has been recycled urine more times than your human brain is able to comprehend.
The only real difference on the space station is that they do a much better job of purifying and testing the water than nature does.
I'm tired of it. Everyone who drinks from a modern city water supply drinks recycled urine because water treatment plants reclaim water from human waste so they dont have to pump so much from the ground. They do it very efficiently too. No one even notices it really.
Of course, since the space station inhabitants drink recycled urine, I'm still not totally convinced that I would want to try that cup.
Wow, I guess Starbucks really is everywhere.
A coiled up plastic tube will achieve the same thing, but a sealed plastic sippy bag is probably still best.
Excuse me, but please get off my Pennisetum Clandestinum, eh!
If I were to drink from a cup in space, I'd need a really long straw.
I'm still not totally convinced that I would want to try that cup.
Char it and you'd never be able to tell it from Starbucks. Chill and carbonate it and it'll pass for Budweiser.

ALL water is recycled. Thirty thousand years ago a mammoth was pissing out the water that's sitting in your coffee urn this morning. People need to get over this, just like they need to get over irradiated food. It's at least as safe to drink as bottled water; And likely moreso since some bottled water undergoes no processing prior to being packaged. Did you know that the LA municipal water supply recycles its sewage into tap water? It's the nation's largest sewage processing station, and as a byproduct it produces several million tonnes of valuable fertilizer that's highly valued for use on the wineries in California. This isn't unique to California -- many coastal cities use similar measures because the rivers are too polluted and they're too close to sea level to find water reserves underground.

Don't drink that! It's not coffee!
Rob, dude, you really should think about some of these stories a little more before posting them. We're all drinking urine (and other much more horrible things) each and every day. It's what those costly water treatment plants on Earth are responsible for filtering, and it's what those expensive systems for the ISS are designed for. What's the difference? Either way the if the coffee tastes good, and it's clean water that's used, I'm happy drinking it :)

Bit of a mistake there, or an out of context missquote: a space vehicle under acceleration doesn't really experience 'weightlessness' therefore there isn't really any problems with scavenging tanks. Surface tension would help to get engines and turbopumps started, logically.
After logging in slashdot still does not take you back to the page you were on. It's been that way for 20 years.
But I wonder who did the A/B comparison.
Maybe they just taste-tested the coffee against a cup from Starbucks.
sigs, as if you care.

Waah waah waah! Recycled peepee! EWWWWWWWW!
OK kids, I know you get all worked up when you haven't had your nappy-time. Maybe this will help: you can drink piss straight out of the toilet bowl with a straw, and it's safe. In fact it would be even safer to whizz right into a cup, because PEE IS CLEANER THAN "CLEAN" TOILET WATER! So please, shut the FUCK up about it being dirty, children.
The more I think about it, the more I believe it probably wouldn't be that tough to convert a standard travel mug design to be zero-G ready. Fit a thumb lever on the top of the handle (think beer stein) to operate a small hatch over the drinking hole, and a squeeze operated handle (think caulk gun) lever which ratchets a plunger up from the bottom of the mug, similar to upright toothpaste dispensers. Why am I pondering this...I need to get back to work.
-=Bang Bang=-
... in some SF novel or another. The design wasn't exactly the same, but the drinking vessel described used the same basic idea of surface tension wicking water out of the container. As the article noted, this is based on a common fuel-tank design. The story had an enclosed container because, well, even in free fall you've got to deal with the occasion fumble-fingered astronaut imparting acceleration to the container along an inappropriate vector. :)

why they don't just use a sippy cup?

You think the recycler is disgusting ?
Think about it a few seconds - your body recycles water from poop.
Admittedly, you don't drink the water, you inject it directly into your bloodstream.
Grossed out yet ?

That doesn't look anymore convenient than using a bag with a straw. Maybe even less convenient since you still have to suck from the sharp edge of the bag. And do you still need to fill it from a bag with a straw like he does in the video?
Interesting though.
Its like that anecdote, that the US spent millions on inventing a ball-tip pen that would work in space while the Russians just used a pencil ^^
and a new, very disgusting, futuristic meme
I am pretty sure what they are referring to are satellites already at their desired orbit.
Once satellites reach their orbit, they don't just sit there. After some time the orbit can start to shift around, so satellites use very small station keeping thrusters.
Most of the time these thrusters are bi-props (MMH and NTO) that use the same tanks that were employed to feed the much larger main engine used to circularize the orbit.
But once the satellite is at orbit, you have a relatively small amount of fuel / ox left in a large, mostly empty tank. So you need some stuff in the tank to hold the enough fuel for a quick firing of a station keeping thruster.
This thruster firing occurs in a "weightless" environment. If there wasn't some apparatus to collect and hold fuel / ox, you could never fire a thruster, which in turn sloshes some fuel / ox around, which is captured by the apparatus, which can be used for the next firing... until there is just no more fuel / ox left and the satellite is "dead".
I believe it is the above set of circumstances he is referring to.
Sir, would you like that urine decaf or regular
People need to get over this, just like they need to get over irradiated food.
What a stupid comparison. Purifying water is just a matter of removing the stuff that you don't want in it. Irradiating food means bombarding it with radiation that undoubtedly causes physical changes. Whether these changes are dangerous is a matter of controversy, and I won't pretend to know enough to have an opinion.
What I do know is that I'm tired of people dismissing whole ranges of opinions because they're too lazy to distinguish serious arguments form the half-baked notions of a few idiots. By that logic, nobody should ever vote Republican ever again because all Republicans are too stupid to distinguish between somebody who's a Islamofascist Terrorist and somebody whose middle name happens to be Hussein.
But of course Republicans aren't like that. They have smart people with legitimate concerns and they have a cadre of total idiots, just like every political or advocacy group. Dismissing the whole group because you can point out the stupidity of a few individuals in that group is itself extremely stupid.

Umm...don't they use pumps? Big, fast ones that can drain swimming pools quickly and such? I don't think rockets are designed to run on capillary action.

I'm having a bit of trouble picturing this...
The horizontal cross section of the mug is a teardrop shape, rather than a circle (like a standard mug). The coffee stays in one clump in the cup due to surface tension. However, at the pointy end of the teardrop, the coffee is drawn towards the mouth of the cup through capillary action. An astronaut may sip the coffee from the pointy end of the mug while the bulk of the coffee remains in the mug. Capillary action will continuously replace the coffee that is being sipped away.

I'll bet it's far purer and safer to drink than the water that comes out of your tap.

What the hell do you think they do with the urine you shoot into your toilet, you bloody cod?
Kopi Luwak coffee brewed with recycled urine? That would be great, I bet.
the coffee drank you out of a straw.
If you don't know what you're doing, you can't make mistakes.
You're soaking in it. We don't get NEW water, dude. Earth is just a huge recycling apparatus. You can't go very far without encountering a few molecules that you've peed or crapped out at some point in the past. Hell if you've ever gone swimming in a public pool or the ocean, that's a lot nastier than anything you're going to find on a NASA space station.

In case you can't view the video or the pictures:
1) Take a piece of paper.
2) Fold it in half but don't squash and crease it. The joined edges are flat together and the rest of the paper tries to form a gentle curve. The midline where the crease WOULD have been is trying to be a cylinder, but the curvature has to reduce, then reverse, to end up with the edges being flat together. The result is a pipe with a cross-section shaped like a tear drop.
3) Now take your teardrop-pipe and fold one end closed. Squeeze the rest so the remaining opening in the other end stays open and teardrop shaped. This is your cup.
4) When you fill it with liquid in zero-G the liquid attaches to the cup by surface tension. It is attracted most to the folded edge, because there's so much more surface in close proximity. Next most attractive area is the closed bottom, so the bulk of the liquid stays down there.
5) Because the join of the edges is so attractive, the blob of liquid reaches an "arm" up the inside of the join, all the way up to the cup's opening. That's where you suck on it. It's like a virtual straw, which doesn't need to completely enclose the liquid.
Make sense now?

No sig for the moment.
Don't look now, but you already drink recycled urine. Stuff goes down the drain, to water treatment, to lake or ocean or golf course. At this point, it evaporates. The water vapor aggregates as clouds, the clouds produce rain. The rain ends up in reservoirs or aquifers, whence comes drinking water.
The cycle is just a little smaller in the space station.
Don't take life too seriously; it isn't permanent.
You rule. Seriously explained a lot.
