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.

Digital Connectors 2015

Me with the Raleigh Digital Connectors, Nov 2015.

Me with the Raleigh Digital Connectors, Nov 2015.


I was invited to give another talk to the Raleigh Digital Connectors yesterday on the topic of blogging. Once again I was inspired by these young men and women who are making a difference in the community. I am always honored to speak to them on the topic of blogging as it’s so important that they know they have this amazing resource known as the Internet with which to express themselves.

Blogging certainly has been a worthwhile endeavor for me. I don’t always get time to write as much as I’d like to but I enjoy the time that I can find.

Take a look at these young people in this photograph. These folks are changing the world.

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.

Curiouser and curiouser

You know the saying, “be careful what you wish for?” Well, it’s really true. I had been pondering lately some of the bigger questions in life and lo and behold I was presented with an opportunity to explore these questions. I won’t go into details but I can say that the world doesn’t look quite the same to me as it did just a few weeks ago. Mind blown.

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.

Renewables critics sound off :: WRAL.com

Fossil-energy advocates are desperately pleading with the NCGA to revoke our state’s clean energy standards called REPS (Renewable Energy Portfolio Standard). Thankfully, they have an uphill battle as large-scale solar projects become a property-tax bonanza for the rural areas where they get built, instantly boosting the property values without requiring any public infrastructure investment.

I used to be worried about attempts like the Koch-backed American Energy Alliance but not anymore. They are this century’s buggy-whip makers, propping up a rapidly-dying industry: coal.

The writing’s on the wall for dirty-energy producers. Clean energy is kicking their ass and it’s only going to get worse for them. Hey Koch brothers, you have no chance of stopping the clean energy revolution, you’d be better off learning how to take advantage of it.

Raleigh, N.C. — Opponents of renewable energy programs held an hour-long roundtable at the Legislative Building on Wednesday about their concerns.The event was sponsored by the American Energy Alliance, the political lobbying arm of the Institute for Energy Policy, a conservative think tank funded by Charles and David Koch. The event moderator was Tom Pyle, president of the AEA and the IEP, and a former Koch Industries lobbyist.

Trying to follow what is going on in Syria and why? This comic will get you there in 5 minutes.

I was not aware until now of the role climate change has played in the Syrian crisis. Pentagon studies have long argued the destabilizing nature of climate change will lead to increased conflict as people fight over diminishing natural resources. We can expect more of this as our environment continues its collapse.

Wars are complex. They come out of nowhere and all of a sudden, people you’ve never heard of are killing each other on the evening news. Here’s what you need to know about the war in Syria — and it’s not oil or religion. It’s something that we’re all creating together.

Alexander: Do those new chip-based credit and debit cards need protection? – StarTribune.com

I was chatting with the cashier supervisor at the local Large Mart, asking if Large Mart would be going to the new, chip-based credit cards.

“Yeah, we’re going to get those within the next few weeks,” he said.

I nodded. “Well, I’ve been the victim of credit card fraud so many times that I welcome the extra security.”

“The new cards also have security problems,” the supervisor answered. “With the chip cards, thieves can read your cards while they’re in your wallet.”

That was news to me. The chip on my card is definitely a contact card, and any RFID-based credit card would be wide open to the world and truly offer zero security. Fortunately, banks aren’t using RFID, but Near-Field Communication (NFC), and only in some chips (i.e., not in the U.S. at this time). NFC has a range of 2-4 inches, which is about 1/12th the range of an RFID tag. Also, an NFC-capable device does encryption, while an RFID tag would only stupidly transmit static numbers.

So, tl;dr: current chip cards in the U.S. are contact-only, and NFC chips won’t be readable outside of your wallet. Bring on the chipped-card revolution, I say!

Q: Do the new EMV chip credit cards (named after the developers, Europay, MasterCard and Visa) require a protective cover so that they can’t be scanned by nearby thieves, just as RFID (radio frequency identification) cards do? Do other radio frequency ID cards, such as hotel key cards, pose a risk of identity theft?
Jan Sartee,
San Rafael, Calif.

A: There are two types of credit cards using EMV chip technology. One is read by a slot in a point-of-sale ­terminal; the other is read by holding the card near the sales terminal.

If your EMV card requires physical contact inside a reader, its transactions and account information can’t be scanned remotely by thieves. If it is a contactless card, there’s a chance it could be read by nearby spying equipment, although the credit card ­industry says that’s unlikely.

Cold Fusion Heats Up: Fusion Energy and LENR Update | David H. Bailey

A friend forwarded this HuffPost story on cold fusion research and I was surprised to learn that a Raleigh-based company called Industrial Heat is said to have working technology.

Perhaps the most startling (and most controversial) report is by an Italian-American engineer-entrepreneur named Andrea Rossi. Rossi claims that he has developed a tabletop reactor that produces heat by an as-yet-not-fully-understood LENR process.Rossi has gone well beyond laboratory demonstration; he claims that he and the private firm Industrial Heat, LLC of Raleigh, North Carolina, USA, have actually installed a working system at an (undisclosed) commercial customer’s site.

According to Rossi and a handful of others who have observed the system in operation, it is producing 1 MWatt continuous net output power, in the form of heat, from a few grams of “fuel” in each of a set of modest-sized reactors in a network. The system has now been operating for approximately six months, as part of a one-year acceptance test. Rossi and IH LLC are in talks with Chinese firms for large-scale commercial manufacture.
