Comment: "Waste" (Score 3, Insightful) 71

While I find the 3d printing damn cool, the editorializing about the waste struck me as an odd comment for subby to make. I'm guessing that a lot of powder gets left over by this new process just as milling from a solid block leaves shavings. But those should be just as easily melted down and recycled in the next job, so not really wasted. (And if they are thrown away, it means that reusing them just isn't economical, so the 'waste' isn't that valuable anyway.)

I think the better argument where 3D wins is the ability to get arbitrary shapes that could be impossible to make with traditional machining or casting.

There's a great short story about an AT-AT test pilot doing war-games for the brass and the weapon's designers. In one test engagement against A-wings he has the new AT-AT kneel down before shooting back. When they ask him why afterwards, he explains that he thought the A-wings might try to trip him up. After horrid stares amongst the designers and their bosses, they decide the best "fix" is to ship his smart ass to Tatooine so they can sweep it under the rug and stay on schedule.

"Inner Light", a favorite. It still gets a little dusty in the room when it's on. The flute went for mondo-bucks at auction, and is one of the rare examples of actual continuity in the show. (Beverly remembering they had a freaking Sun Shield a few episodes later. And using it once! Being another rare example) I will say that the Wesley episode with Ashley Judd had....redeeming qualities. And disqualifies Wil Wheaton from complaining, ever, about being Wesley.

So this wasn't an equipment failure requiring a backup, but just market price fluctuation: The cost of natural gas per Watt generated went above the cost per Watt of the fuel for the backup generators, due to the high demand for natural gas as demand rose as temperatures fell. Sounds like Econ 101.

1. Why didn't the wholesale electric prices rise in tandem with the gas price to keep generation economical? Capped by fixed residential rates?

2. Why didn't the generators use the derivatives market to hedge against spikes in gas prices so they'd be able to keep buying as demand/price rose?

Unfortunately the trend seems to be to optimize the site for mobile (all of them, at once) and say to-hell-with-PC-browsers. With extremely minimalist, Metro-like, stripped-of-any-useful-information pages now. So now the question has become "why do websites suck?". Lowest Common Denominator experience. Meetup.com went this way a few months ago and is now a shadow of its former self.

The cost of feathers has risen, even down is up!
