Comment Re:And ticket prices? (Score 4, Insightful) 117

American corporations will instead do the following.

Get a government grant for the coatings, claim the actual full purchase price at full retail as the cost and pass that cost to ticket buyers.

Use the 5% fuel savings as a ,"we are saving the planet.... see? SEE?" advertising campaign.

Also add the costs of the advertising to the ticket prices.

Profits go up an additional 75%, claim they need more government subsidies.

Comment Re:GM Diesels (Score 1) 249

Plus the "small" issue that until recently the EU didn't regulate NOX, so eurodiesels didn't comply with USA limits.

And for the years before we regulated NOx? All through the 70s, 80s, and 90s?

USA diesel in most areas is still filthy despite reduced levels in the last 5 years.

Where do you live that this is the case? Pumps have had ULSD since Jan 1, 2007. There were maybe a few exception areas but I think those were all phased out by 2010. They're now moving to ULSD for off highway diesels as well.

"Grand" money? What's that?

Typo, Grant money.

What nonsense. 15 years ago was the year 2000. Has human genetics changed? Have computers changed so much?

What does anything have to do with genetics? And computers have changed. You don't need a multi-thousand dollar AutoCAD or CATIA license to do modeling.

Why do you post such utter nonsense?

Why do you post as AC?

Comment Re:For What Are You Using 3D Printing For? (Score 5, Interesting) 266

It has a use for some small, niche scenarios, but it doesn't do anything for most of us here, and I really wish we would stop seeing stories on it every other week.

With a 3D printer you could run a ~19th century machine shop from your own home. You don't use the 3D printed model. You use it to check fit up and then to turn it into molds.

You can melt iron with used motor oil even charcoal. Sand casting is still used almost everywhere for cast iron.

Give me a 3D printer big enough and I'll build you a tractor. Engine and all.

Comment Re:plastic is for junk (Score 2) 266

Who cares? I want my plastic to melt at 105C. I want it to melt at just above room temperature.

I can make molds. Anything I can think up to print I can turn into a mold for metal. With a furnace and some wax I can cast iron.

9L+ diesel engines are still cast. If your bed as large enough you could 3D print yourself a small 2 stroke engine, check for fitup and then build yourself an entire engine from scratch.

"Die Cast" used to be a marker of quality. With a 3D printer at home you can make anything the average machine shop could have made during the industrial revolution.

And because you can do it in 3D with cheap plastic first you can reduce costs. You think a bad 3D print job is expensive? Imagine screwing up a mold design for a 12L engine.

Comment They're not for you. (Score 1) 266

They're for your kids. I'm shocked at the number of Slashdotters that are talking about 3D printers like this.

Our local library bought one through Grand money and there are kids in there every week trying to learn to use it. MakerBot and Thing Verse work really well together.

It's how I learned how to Program. First I copied someone's program. Then I modified someone's program. Then I wrote my own programs. Kids are printing things out. Some get bored with it, some spend a lot of time with it. Guys are making desk top figures or monster trucks. Girls are 3D printing jewelery. The librarian has asked me to help out with teaching them some 'theory' behind stuff and I just gave them my parametric modeling book from freshmen year in college.

There are 10 year olds out there that can model better than your average college senior could 15 years ago. FIRST robotics is going to get a lot more interesting when you have people that can actually model. People that may be contracting your CNC shop to make a part. Kids that have grown up doing parametric modeling and actually know how to design for machining. (Because if they screwed it up on a cheap piece of ABS plastic and not your CNC machine.) There are going to be girls that will be asking their parents for a Revo 540CX CNC machine so they can make their own rings.

Root and install a blocking hosts file.

  Bethesda proved that ad's on free games is only for complete crap games. Fallout shelter has ZERO ad's ZERO nags, and they are making money hand over fist with it.

So if your app has ad's, it's a strong sign that it's a complete crap app.

Luckily 99% of all free apps are trash, so I dont use them, the ones that are worth buying, I buy.

Comment Re:Are We Too Quick To Act On Social Media Outrage (Score 1) 371

NPR also had a few interviews with the author of So You've Been Publicly Shamed .

Most of the examples were people that made tongue in cheek jokes to a small audience (their friends) and someone got 'outraged' at it and then they had the entire internet doxxing them and trying to ruin their lives.
