Comment TL;DR - the Why of it (Score 2) 467

It isn't until you get to the last paragraph that TFA finally gives you the underlying cause of this astonishingly shortsighted and imminently disastrous decision:


  • “Climate science becomes secondary to business; business comes first ,” Spash said. “The interests of the corporate sector, of the mining and resource extraction industry, are primary in Australia.”

So there you have it. The ability to make money trumps EVERYTHING. Kind of answers the question of why we never see aliens. If all intelligent species tend towards a capitalist society, they all end up committing environmental suicide.

he hasn't been touching the email issue, probably because it's contaminated.

He's treating her with kid gloves, because he wants something from her.

You mean that Sanders would be vice president. The alternative to that - I don't want to go there, too much lemonparty association.

No, he wants her to be his vice president, and that only makes sense if he doesn't sully her too much prior to his nomination.

But TRUMP...is somehow ELECTABLE (let alone not a real traitor)?

Finally, someone who isn't using fake accounts to spam Slashdot with anti-Democratic Party crap.

There isn't a single "electable" Republican running right now. So the question is, which Democrat is going to be the President? The only part of this election that's in question will be settled by the Democratic Party primaries.

It's her old office (you know, the Obama State Dept.) that is slow rolling out the emails. But only because they were forced to. Otherwise we probably wouldn't have seen any of this for decades.

They should have done it like the Bush administration -- they routed their emails through a private email server controlled by Karl Rove so they could all be deleted once an investigation started.

Obama, what a rookie.

Comment Re:Remember the NASA Wind Turbines? (Score 1) 180

Current blades are trucked in one piece (per blade) which is impressive to see. Three of them were parked on I-5 outside of Patterson, California a few months ago. There are a lot of net videos and photos which convey the scale.

Even at the current size they can't get through many highway interchanges and local intersections. The larger ones won't be able to ship in one piece at all.

Comment Remember the NASA Wind Turbines? (Score 4, Interesting) 180

NASA Wind Turbines approached this scale in the '80's. Unfortunately, this was a previously-unexplored area of aerodynamics for NASA, and they had mechanical stress and noise problems (including subsonics) and were all demolished. I think there was one near Vallejo, CA being taken down when I got to Pixar in '87, and one in Boone, NC, which famously rattled windows and doors.

The art has since improved. I took a ride to the top of the turbine at Grouse Mountain, that was fun! That's the only one I have heard of where you can actually get to see it from the top.

Comment Starting out with the wrong assumptions (Score 2) 165

This is starting out with the wrong assumptions.

Design a brick system that can be produced with 3-D printers, and will hold together when fabricated within the tolerances of an SLA printer. Forget FDM, it's too low precision and SLA is already achieving an equal or lower cost of manufacture compared with FDM.

LEGO is manufactured to astonishingly high precision, but I am not convinced that this is the only way to make a brick system.

Comment Re:No comparison (Score 1) 132

Blue Origin will eventually have a two-stage rocket that can reach orbit (although they are planning on a much smaller payload than SpaceX for their first iteration). When the booster of that rocket lands without damage, they will duplicate what SpaceX has recently done, although in smaller scale.

Blue Origin to SpaceX at present is a sort of bicycle-to-automobile comparison if you account for the tremendous difference in energy and the application. So, I think there really is an intrinsic difference between the two of them.

If you want to say there's no intrinsic difference, then we need to look at Orbital's Stargazer and Pegasus, which have been carrying small payloads to orbit for years, and there's only been one Stargazer all of that time so there is no question that it's reusable. The only difference is that Stargazer lands horizontally.

We can then look at the B-52 and X-15 combination, in which both stages were reusable, a human was the payload, and we're going back to the late 1950's.
