How to Charge $546 for Six Liters of Saltwater
- a brief story of the humble bag of saline solution given intravenously at ERs and hospitals, and how one unit of it can be marked up from 86 cents to $91 when given to patients
Defense contractor takes break from F-35 JSF, finds a way to eliminate 99% of the energy cost of desalination.
Lockheed-Martin has developed a way to craft sheets of carbon a single atom thick, which can filter the salt (and just about anything else) from water with a tiny fraction of the energy required by current processes. "Lockheed officials see other applications for Perforene as well, from dialysis in healthcare to cleaning chemicals from the water used in hydraulic fracturing, or "fracking," of oil and gas wells."

Should we be reducing our salt intake? Maybe not.

Time lapse videos can be breathtaking, lovely, and a joy to watch… but they can also show you something you may not have thought about before. Before I even read the caption for Murray Fredericks’ video called "IRIDIUM", I knew it was filmed in the southern hemisphere. Can you guess how? [more inside]
Why Wal-Mart Is Making Our Health Its Problem
- "So what's behind the [healthier-eating] initiative
? In a word: scale. In a recent article in HBR
, Chris Meyer and I argued that we'll see companies taking more and more ownership of externalities they could ignore because of changing sensibilities and better sensors (meaning detection and reporting of impacts by third parties). But we also identified a third driver: the scale of modern business. Whereas in the past, a single grocer could not have much impact on society, in today's highly consolidated market, Wal-Mart touches a significant percentage of the nation's food intake. Once you reach a scale where your decisions have ramifications for millions, it is hard to pretend that the impacts, even as distant ripples, are not your problem."
Another oil spill took place this weekend. 21,000 gallons from a Chevron pipeline leaked into the Red Butte River
, which runs through the center of Salt Lake City and feeds the ponds in its largest city park, Liberty Park
. Also affected was Tracy Aviary
Researchers at MIT and in Korea have developed
a new, efficient desalinization nanotechnology
that could theoretically lead to small, portable units
powered by solar cells or batteries, yet deliver enough potable fresh water from seawater to supply the needs of a family or small village
. As an added bonus, the system would simultaneously remove many contaminants, viruses and bacteria. MIT Press Release

Obesity: The killer combination of salt, fat and sugar
- "Rewarding foods are rewiring our brains. As they do, we become more sensitive to the cues that lead us to anticipate the reward. In that circularity lies a trap: we can no longer control our responses to highly palatable foods because our brains have been changed by the foods we eat." [more inside]
The globe’s networked ecologies of food, water, energy, and waste have established new infrastructures and forms of urbanism. While these ecologies exist at the service of our contemporary lifestyles, they have typically remained hidden from view and from the public conscience. Infranet Lab

Following the death of his sister to brain cancer, Motoi Yamamoto
adopted salt as his primary artistic medium. In Japanese culture salt is not only a necessary element to sustain human life, but it is also a symbol of purification
. He uses salt in loose form to create intricate labyrinth patterns
on the gallery floor or in baked brick form
to construct large interior structures. As with the labyrinths and unnavigable passageways, Motoi Yamamoto
views his installations as exercises which are at once futile yet necessary to his healing.

Wieliczka Salt Mine

Needless to say, this has given the miners plenty of time to carve some pretty amazing things.

Is blood plasma salinity the same as seawater?
No, but that proves evolution. "The answer is most definitely NOT that oceans were 1/3 as salty back then. It most definitely IS that the earliest vertebrates did evolve in salt water and then moved into fresh water....They have devised an extremely clever trick in kidney structure to allow salt transport pumps which really take salt back INTO the body from the urine but still manage to use them to produce urine much more concentrated that their body fluids and so excrete salt FROM the body."
Not just a condiment, salt is a major force
shaping our world. In Australia, what do you get
when you combine ancient salt-pans with European farming practices? In one state alone, we're losing a football field an hour to the salinity crisis. What do you farm
when all you have is salt?

Is Salt The New Olive Oil?
The New York Times
] thinks so and Peter Hertzmann
, on his superb a la carte
website, offers an expert analysis of the difficulties of seasoning well. Even the greatest chefs feel insecure with salt, even though most of them would consider it to be, by far, the most important ingredient of all. At least those I've asked. [I always ask them what 3 ingredients they couldn't do without
]. It's cheap; it's essential and there are now so many kinds to choose from. Will this current brouhaha be enough to convince the larger population that much is lost
in using only the industrial, refined stuff? [Of course, for someone from Southern Europe, olive oil and good sea salt aren't exactly new, so take this with a grain of you know what.
Talk about holding a grudge. Thirty-six years after its initial publication, the Wacky Pack sticker for "Moron Salt
", a toothless parody of Morton Salt
, has become perhaps among the more sought after of all non-sports collectible cards. Why? Because to this day, the makers of Morton Salt are vigorously attempting to banish it from the face of the earth, including going so far as to threaten legal action
against eBay to get them to delist anyone trying to sell it. Details on the legal battle (as well as much more Wacky Pack goodness) available at MoronSalt
