Yep. Some parts of the Merlin 1D are built additively, I think, but the *entire* SuperDraco thruster (which uses Hydrazine rather than cryogenic fuels like RP1/LOX) is printed. http://en.wikipedia.org/wiki/S...

It's really cool to see this technique taking off (pun not initially intended, but let's go with it). People think of 3D printing as making rough plastic parts, but it can be used to create extremely precise parts out of various metals, too.

If they're renting (as most low-income people do), they won't be (directly) paying property tax.

I suspect Lucas doesn't actually expect to turn a profit on doing this, possibly not by a long shot. 200M isn't exactly pocket change, but he can easily afford to write off the whole thing if needed.

It's pretty sad that "rich guy flips the bird to other rich people in revenge for not getting his way" pleases you more than "rich guy helps people get housing in one of the most expensive parts of the world". I mean, I enjoy the feel of a good "fuck you!" too, but if you like that *more* than what's essentially charity, well, that's kind of screwed up of you...

Seems like a reasonable claim to me! Resource supply is one of the key determiners of land value, and always has been. If it rains on my land, and I catch that rain before it wanders onto somebody else's land, how is that not my water?

I mean, there's lots of arguments for (and against) communal ownership of natural resources, but the current (and, for as far back as I'm aware, historical) rule is that they are part of the land value. You're going to have a hell of a time overturning that view. Some things, like rivers, tend to get a bit complicated - it's really awkward if your upstream neighbor feels like using his water (immediately before it ceases to be his) as an arsenic dump - but taking ownership of the water falling from the sky or coming up through the ground has never, so far as I know, *not* been part of land property rights.

It's certainly not cost; executing someone costs far more than life does.

Ok, morality and ethics aside for a moment...BULLSHIT! As the other poster pointed out, the cost of legal proceedings, food, shelter, and correctional facility staff get expensive. However, the cost of the actual materials involved in execution and cremation (burial and funeral paid by family if they wish) is far less.

Me? If members of ISIS are going to continue down a path of heinous activities then I vote we drop them where they stand. In fact, there's no honor in killing. Lets me honest about this. No, just drone strike them from above. The idea of a moral high-ground is a bunch of feel-good BS. If they remain a threat, just eliminate said threat.

Judge me how you wish, but I'm all about results. And if I had my druthers, you would get solid results! Just know full well you wouldn't agree with how I could achieve them.

War is hell, and we're all hypocrites. So be it.

I'm not actually sure which of use that tweet backs up; I thought he meant "I estimate we have an 80% chance of at least one landing by year's end, because there are lots of launches between now and then and there's a pretty good chance at least one will succeed." It would be pretty awesome if what he meant was "By the end of the year, we'll have so much more launch practice that, even though each launch has less than 50% chance of recovery right now, by year's end it should be about 80%." I hope the latter is the case, but the two are very different statements and the latter is much more optimistic. I was hoping you could indicate which one was more accurate.

Killing terrorists isn't so much as judgement as it is a confirmed method of neutralizing a threat that poses a clear a present danger. Otherwise, we wouldn't be incarcerating them in the first place. I'm sure many soldiers would be better off not capturing them in the first place as it puts their own lives in danger to do so.

+ - If Earth never had life, continents would be smaller-> 1

Submitted by sciencehabit
sciencehabit (1205606) writes "It may seem counterintuitive, but life on Earth, even with all the messy erosion it creates, keeps continents growing. Presenting here this week at the annual meeting of the European Geosciences Union, researchers say it's the erosion itself that makes the difference in continental size. Plant life, for example, can root its way through rock, breaking rocks into sediment. The sediments, like milk-dunked cookies, carry liquid water in their pores, which allows more water to be recycled back into Earth’s mantle. If not enough water is present in the mantle about 100 to 200 km deep to keep things flowing, continental production decreases. The authors built a planetary evolution model to show how these processes relate and found that if continental weathering and erosion rates decreased, at first the continents would remain large. But over time, if life never evolved on Earth, not enough water would make its way to the mantle to help produce more continental crust, and whatever continents there were would then shrink. Now, continents cover 40% of the planet. Without life, that coverage would shrink to 30%. In a more extreme case, if life never existed, the continents might only cover 10% of Earth."

I heard GW Bush claim Saddam had WMDs too, and that didn't happen did it?

Actually, that one did. It resulted in both "Gulf War Syndrome", and a pretty big scandal where Monsanto brokered the deal to sell the machines to manufacture chemical weapons to them from a German company, said deal routed through France. But nice try.

PS: Plus we sold them the Sarin the used against their Kurdish separatists directly, so we knew they had it at one time, and were just hoping they hadn't used it all up so we could say "Aha! Stockpiles!".
