Scientists have figured out how to shock the salt out of seawater – ScienceAlert

Cool!

Researchers have developed a system that uses an electric shockwave to extract salt and other impurities out of salty or contaminated water, and say it could be scaled up for use in desalination or water purification plants, or be used to clean the vast amounts of dirty water produced by fracking.

Known as ‘shock electrodialysis’, the technique applies an electrically driven shockwave to a constant stream of flowing water. The current interacts with the charged salt particles, causing a stream of salty water to be pushed aside and separated from a stream of fresh water, and these are then funnelled into separate pipes.

A Bold Future that Wasn’t: the NS Savannah

Behold the future.

The NS Savannah was the world’s first nuclear-powered merchant ship. She steamed for over 400,000 miles from 1962 to 1970 as the flagship of President Eisenhower’s “Atoms for Peace” initiative, but her operational costs, meager cargo capacity, and the extensive training required of the crews doomed her. She now resides at Pier 13 in Baltimore awaiting the removal of her reactor and can be toured upon request.

This site gives you a virtual-reality look at this forgotten engineering and design masterpiece. It’s a walk back in time to the more hopeful, futuristic outlook of the late 1950s. I’d love to see it in person (and it can be done by following the instructions in this FAQ list).

Welcome to the Nuclear Ship Savannah, the world’s first nuclear-powered merchant ship.

Savannah was a signature element of President Eisenhower’s Atoms for Peace program. She was constructed as a joint project of the former Atomic Energy Commission (AEC) and the Maritime Administration. She operated from 1962 to 1965 in experimental service, at which time the AEC issued her commercial operating license number NS-1. Savannah continued in demonstration service as a cargo ship until 1970 when she ended her active career. She was defueled in 1971 and her reactor made permanently inoperable in 1975-76. About 95% of the power plant is intact and remains onboard ship. Savannah is still licensed by the Nuclear Regulatory Commission (NRC is the successor to the AEC), and will remain so until nuclear decommissioning.

One big reason REI can decide to skip Black Friday – The Washington Post

Am I the only one sad that a retailer chooses NOT to make it’s employees work over Thanksgiving is newsworthy? Is this how far we’ve fallen? Does America really worship the almighty dollar this zealously?

Outdoor retailer REI made an announcement Monday that may have sounded like sacrilege to retail industry veterans. It will be closed this year on Black Friday, shutting its doors on retail’s holiest of days and paying its employees for a day off. Some hailed it as an unprecedented move, especially at a time when many other retailers have turned even Thanksgiving itself into a day of holiday shopping.

Little kids in Japan are independent – Business Insider

There are no helicopter parents in Japan.

It’s a common sight on Japanese mass transit: children troop through train cars, singly or in small groups, looking for seats.

They wear knee socks, polished patent leather shoes, and plaid jumpers, with wide-brimmed hats fastened under the chin and train passes pinned to their backpacks. The kids are as young as six or seven, on their way to and from school, and there is nary a guardian in sight.

NC budget is a fiscally responsible Goldilocks document | News & Observer

N&O contributor J. Peder Zane sometimes gets it right (see Confederate monument) but the rest of the time he lives in a libertarian paradise that, frankly, doesn’t exist.

Read how he pooh poohs the Renewable Energy Investment Tax Credit, calling its repeal a “free market prod.” Well, it’s news to me that Duke Energy’s state-chartered monopoly on electricity is a “free market.” I was never the best student but I do seem to recall learning in school how a monopoly is pretty much the opposite of a free market.

I can’t wait to get this electricity free market that Zane promises. I’m sure that killing off competition is the best way to get it, right J. Peder?

Allowing the renewable energy investment tax credit to expire may be the best thing to happen to the green sector. Replacing the crutch of state support with the free market’s prod is our best hope of developing cheap, efficient renewables. It also addresses the fact that these well-intentioned subsidies have become a form of crony capitalism, sopped up by big corporations.

Why Republicans are starting to panic, in 1 paragraph – The Washington Post

Summer is over. And Donald Trump is — still — at the top of the 2016 Republican primary field.That makes lots and lots of Republicans with an eye on winning the White House in 2016 (or even 2020) very, very nervous.

That unease — and its origins — are explained brilliantly in this paragraph, taken from a broader piece entitled “The GOP is Killing Itself,” by former Bush administration official Pete Wehner:

The message being sent to voters is this: The Republican Party is led by people who are profoundly uncomfortable with the changing (and inevitable) demographic nature of our nation. The GOP is longing to return to the past and is fearful of the future. It is a party that is characterized by resentments and grievances, by distress and dismay, by the belief that America is irredeemably corrupt and past the point of no return. “The American dream is dead,” in the emphatic words of Mr. Trump.

Filmmakers fighting “Happy Birthday” copyright find their “smoking gun” | Ars Technica

A judge has ruled that Warner/Chappell’s claim of the song “Happy Birthday” is invalid and the song is in the public domain. This has long been a notable case of copyright abuse and it’s thrilling to see it finally corrected.

It’s been two years since filmmakers making a documentary about the song “Happy Birthday” filed a lawsuit claiming that the song shouldn’t be under copyright. Now, they have filed (PDF) what they say is “proverbial smoking-gun evidence” that should cause the judge to rule in their favor.

The “smoking gun” is a 1927 version of the “Happy Birthday” lyrics, predating Warner/Chappell’s 1935 copyright by eight years. That 1927 songbook, along with other versions located through the plaintiffs’ investigations, “conclusively prove that any copyright that may have existed for the song itself… expired decades ago.”

Jimmy John’s CEO under fire for alleged hunting photos – Business Insider

I will never eat at Jimmy John’s again.

Jimmy John’s founder and CEO Jimmy John Liautaud is under fire after photos of him allegedly posing with dead elephants, a rhinoceros, and a leopard appeared on the internet. The photographs, allegedly taken during a 2010 safari in Africa, have sparked calls for a boycott of the sandwich chain, Grub Street reports.

What Programmers Want | Michael O. Church

Interesting take on what motivates a software engineer. This is three years old but surprisingly relevant.

Most people who have been assigned the unfortunate task of managing programmers have no idea how to motivate them. They believe that the small perks (such as foosball tables) and bonuses that work in more relaxed settings will compensate for more severe hindrances like distracting work environments, low autonomy, poor tools, unreasonable deadlines, and pointless projects. They’re wrong. However, this is one of the most important things to get right, for two reasons. The first is that programmer output is multiplicative of a number of factors– fit with tools and project, skill and experience, talent, group cohesion, and motivation. Each of these can have a major effect (plus or minus a factor of 2 at least) on impact, and engineer motivation is one that a manager can actually influence. The second is that measuring individual performance among software engineers is very hard. I would say that it’s almost impossible and in practical terms, economically infeasible. Why do I call infeasible rather than merely difficult? That’s because the only people who can reliably measure individual performance in software are so good that it’s almost never worth their time to have them doing that kind of work. If the best engineers have time to spend with their juniors, it’s more worthwhile to have them mentoring the others (which means their interests will align with the employees rather than the company trying to perform such measurement) than measuring them, the latter being a task they will resent having assigned to them.

The Jet fuel; How hot did it heat the World Trade Center?

The Federal Emergency Management Agency (FEMA) report into collapse of the WTC towers, estimates that about 3,500 gallons of jet fuel burnt within each of the towers. Imagine that this entire quantity of jet fuel was injected into just one floor of the World Trade Center, that the jet fuel burnt with perfect efficency, that no hot gases left this floor, that no heat escaped this floor by conduction and that the steel and concrete had an unlimited amount of time to absorb all the heat. With these ideal assumptions we calculate the maximum temperature that this one floor could have reached.

“The Boeing 767 is capable of carrying up to 23,980 gallons of fuel and it is estimated that, at the time of impact, each aircraft had approximately 10,000 gallons of unused fuel on board (compiled from Government sources).”

Quote from the FEMA report into the collapse of WTC’s One and Two (Chapter Two).

Since the aircraft were only flying from Boston to Los Angeles, they would have been nowhere near fully fueled on takeoff (the aircraft have a maximum range of 7,600 miles). They would have carried just enough fuel for the trip together with some safety factor. Remember, that carrying excess fuel means higher fuel bills and less paying passengers. The aircraft would have also burnt some fuel between Boston and New York.

“If one assumes that approximately 3,000 gallons of fuel were consumed in the initial fireballs, then the remainder either escaped the impact floors in the manners described above or was consumed by the fire on the impact floors. If half flowed away, then 3,500 gallons remained on the impact floors to be consumed in the fires that followed.”
