I'm gonna have to do some checking to see how I'd get aluminum fluoride; I'd prefer not to store hydrogen-fluoride in my house; that's scary stuff. But beyond that, yeah, I'm also kinda tempted to try this one myself.
For anyone interested, Ammonium fluoride is a rust-remover and also used as a toilet-bowl cleaner. Argon is used by welders; I've got some chained up outside my basement. Potassium hydroxide is the historic form of lye. You could likely use the more commonly available sodium hydroxide, which is sold as drain-unclogging crystals. I happen to have some potassium hydroxide on hand because it's sometimes used in setting certain fabric dyes. hydrochloric acid, aka muriatic acid is used for etching cement prior to painting it. You can get it by the gallon at the hardware store.
Platinum/calomel is a bit weirder, but another commenter said that any reference electrode would be fine.
Waterproofing the thing was the first feature I've seen in awhile that made my life easier. That was what, 3 years ago?
I've personally never cared about screen to body ratio or thickness, but that seems to be what manufacturers have been in love with improving for the past decade. I'd much rather have a thicker phone with higher performance than a thinner phone that performs about the same. And I'd much much rather have my speaker facing me on the front of the phone where it fucking belongs.
Part of me wishes that whole modular phone idea would take off; but I'm fairly certain that's a nonstarter. The ability to select the size of the battery based on personal preference would be pretty sweet. An agreed-upon standard for camera lens mounts would be incredible. And I continue to miss the physical qwerty keyboard from my Nokia N900 (rest in peace, you magnificent bastard).
Adam Gazzaley has been doing lectures on this topic for over 3 years now. His gadgets much have really been distracting him to only just now finally publish a book on the topic. I'm curious how well his book is gonna sell given that the concept at least is pretty old news at this point...
"Catalyst" means it isn't directly expended in the reaction. So the cost of a catalyst doesn't particularly matter. That's why there's platinum currently catalyzing your engine exhaust into CO2.
Umm...Generally when something is published by your own school's library, that's what's known as a vanity-publication. That means this study did not undergo peer review. Add the fact that it's funded by Microsoft, who has a massive potential vested interest in the future of AR gaming. Something tells me there's gonna be some gorgeous cherry-picking of data and referenced sources going on in this thing.
No one is asking for the return generated as a result of the audit. People are asking for the return that he submitted to the IRS. If the audit reveals that the return was a complete fabrication or slightly flawed (and I doubt it will), that's a separate issue. There is nothing preventing him from disclosing a copy of what he originally sent to the IRS.
You know another word for that ozone released at low levels? Smog. A better title for this article would be "Smog-Sucking Tower that Doesn't Suck Smog, Just a Little Bit of Particulate...Oh, Also, it Creates Smog".
This is the same principle behind that "Ionic Breeze Quadra" that you used to see on TV commercials all the time. There were two problems with it: 1-when the plate gets dirty, it stops working. You fix this by adding mechanical scrubbers, which the tower no doubt has. 2: these devices produce O3, aka Ozone. When you produce Ozone in the lower parts of the atmosphere, we call it "smog"
So yeah, this thing is doing the opposite of what it claims. This thing produces smog.
Saudi Arabia has a whole set of laws governing how single men and women are allowed to interact with each other. I think it's a terrible idea to extend these laws to online interaction with foreigners. But, apparently, enough people over there think it is appropriate enough a thing to do that an arrest was made.
No. Have you read slashdot comments lately? Slashdot has become the outlet of angry emasculated socially-inept dorks who rail and shout at their "SJW" boogeywoman because everyone capable of actual intelligent discussion has long ago given up on this website.
It's perfectly reasonable to share this story; it relates to that nebulous concept known as Internet culture, and how it is perceived by society. You're welcome to think that the story is inane, but it's still good to know that it exists as a news item.
Yeah, the DC metro is currently getting worried about that last bit because of shutdowns related to massive repairs it's undertaking. Although that's just one of a long list of problems with that system.
Germany is pretty decent with using renewable energy sources. The sources I can find say it's over 25% and rising. Electrified rail may be a better way to go efficiency-wise, but that requires running a bunch of copper along existing railways; and mining copper and then purifying it via electrolysis takes quite a lot of energy. So at least for medium-term, hydrogen makes sense.
You seem to indicate in the comments that you can't exactly point out what these problems are that we should be solving, or what sort of solutions we might come up with to solve these problems. Innovation constantly has the same problem. Two things drive innovation: identifying the root cause of something out there needing improvement, and other innovations. The way you come up with new stuff is by being aware of new technology and innovations, and being aware of problems that these innovations could apply towards. This is extremely difficult, and often massively speculative.
If you start to innovate by first trying to identify a problem, then with enough investigation, you'll find out that the problem hasn't been solved yet for darned good reasons. There's often a topic that gets discussed along the lines of Connecticut Yankee in King Arthur's Court: What could you "invent" to change the world if you suddenly found yourself trapped a few centuries in the past?
Lots of knowitall people will show up and claim things like they'd be able to build a working steam-engine in the early iron-age. But no, even among talented engineers, most of them couldn't. And it's not just because they don't remember how to build one; it's because the state of metal fabrication was such that you wouldn't be able to afford the sheet metal needed to make the boiler; and even if you could; there's a good chance you'd have a boiler explosion. Also, you'd need to build a decently high precision metal lathe; which again, would require massive resources.
To solve something, you need a problem, you need a solution that will actually work (which is an uncertainty until you've implemented the solution), and you need the resources, either acquired by yourself, or someone who you've convinced to invest in your idea to both pay for the resources needed to make the solution, and that includes enough money to cover your basic survival needs while implementation takes place.
So, finding a solvable problem is hard, knowing the solution to the problem is hard, the implementation is usually hard, because it tends to involve unknowns, and finding backing is hard. Compare that to a company willing to pay you enough money to buy a house and raise a family for doing something useless like re-implementing Candy-crush so that it works on your smart-fridge. So some people choose comfort, some choose to fight the good fight. Among those people, some of them have selected a problem that will be solved better by someone else, or a problem that isn't nearly as big of a problem in the world as they though. Some people will have a solution that turns out to fail. Some will have a working solution that depends on an innovation that won't exist for decades to come. Some people will have a great problem and a working solution, but they can never communicate their ideas to someone to the extent that they are willing to back the endeavor.
So yeah, we aren't solving important stuff because pretty much by its very nature, important stuff is Hard to fix, or it would've already been fixed.

(Oh wait, I can't read good. Aluminum fluoride....Yeah, I can't think of any good ways to make that with household stuff.)

Yeah, I dunno about the reliability of this study...although I kinda want that shirt.

it's called "prejudice", "bias" or "preconception" folks :P
Nah, I'm pretty sure it's called "trolling".
Hey, msmash, Why do you have that phrase set up as an anchor, but didn't include a link along with it?
"Rekindle" is a curious word choice to use when talking about a tablet ;)
Who??
Really, Slashdot? Clickbait? "Because it's better". Would that have been so difficult to throw into the Summary? I'm ashamed.
