Hotel in Belfast charges $41 for bottle of melted iceberg water


The Merchant Hotel in Belfast employs two water butlers to help patrons select the right kind of H20 to match their meal. "Whilst experts can differentiate between the mineral content and PH balance of different types of water, discerning consumers are also increasingly demanding a wider choice of waters," Merchant Hotel's general manager Gavin Carroll told the Belfast Telegraph. Cheapskates can get away with an $8 bottle of Speyside from the UK Scotland Glenlivet Estate, while those desperate to impress will order the $41 bottle of Iceberg from the Canadian Arctic Ice shelf in Newfoundland.

From the restaurant's water menu:

In the Canadian Arctic, the snow froze and compacted into enormous glacial walls, sheltered from all impurities from the outside world. Thousands of years later, the ice is considered to hold the purest water on earth. The water has the lowest mineral content of any bottled water, resulting in a smooth and neutral taste.

The issue with arsenic


Arsenic. Hearing the word in America usually brings up black and white mental images of the film "Arsenic and Old Lace." Yet, it is not an old issue. People around the world are exposed to dangerous levels of arsenic in their water.

Speaking today at the American Geophysical Union, Lex van Green discussed the issue of arsenic in well water in the Asian sub-continent, primarily in Bangladesh and Bihar, India. His concern is that even though people are aware of the problem, very little is being done to address it.

People continue to drill new wells without determining their safety (safe levels are set at less than 10 micrograms per liter of water). Van Green's data, collected from 2012-13, show that 50% of people in the area assessed drink water containing arsenic at unsafe levels. However, 100% of people live near safe wells. Additionally, only about a third of people who become aware that their wells are contaminated switch to new wells by either drilling new wells or using their neighbor's wells.

The difference between a safe well and an arsenic contaminated well is depth. Sedimentation by ancient arsenic rich waters along river deltas left layers of arsenic containing soil near the surface of the Earth. To get past the arsenic to clean aquifers, one has only to drill deeper than 100 meters down. However, wells are expensive to drill, and the deeper the well, the more expensive it will be.

So, the problem in these areas where there is no infrastructure to deliver treated water to people boils down one of inequality. Read the rest

VIDEO: Hallucinatory NARCOSE captures free diving's beauty and danger (NSFW)


Thalassophobes and NSFW-phobes will want to skip this beautiful short about deepwater free diver Guillaume Néry and the kinds of hypoxia-induced hallucinations he experiences when free diving to depths beyond 100 meters. Thalassophiles who love beautiful underwater cinematography and trippy dream sequences will find the underwater footage hypnotic. Read the rest

Charity:Water's powerful video on water in Mali and Niger

Rael Dornfest from Charity:Water says, "Today is a huge day at charity: water as we launch our annual September Campaign. It's our biggest campaign ever as we try to raise $4 million to bring 100,000 people clean water in the Sahel region."

"The key to our campaign is a powerful 6 minute video our team shot earlier this year in Mali and Niger. Women there pull dirty water by hand out of 60 foot holes in 100 degree heat. Access to clean water completely transforms their lives."

History of the Slip 'N Slide

My wife (and kids) are big fans of the classic Slip 'N Slide on a summer day. The New York Times Magazine has the history of its invention which involved belly-flopping on a concrete driveway.

Like any concerned father with ready access to rugged, waterproof synthetic fabrics at work, Robert Carrier took home a 50-foot roll of beige Naugahyde in hopes of persuading his son to splash down on something safer. He unfurled it in the yard, hosed it down and watched as every kid in the neighborhood showed up and stayed to slide for hours.

Realizing he had a hit on his hands, Carrier used his sewing skills to refine his product. “He stitched a long tube along one side, sewn shut at one end, with spaces between the stitching so that when you attached the hose, the water pressure would build up and water would squirt out those openings and lubricate the surface of the material,” (explains Tim Walsh, author of "Timeless Toys: Classic Toys and the Playmakers Who Created Them.")

Crowdfunding the Drinkable Book: a book of silver-doped water-filters for the developing world

Jonathan writes, "The Drinkable Book is a water filter and an instruction manual for how and why to clean drinking water. The drinking paper uses a thick, sturdy sheet of paper embedded with silver nanoparticles, which are lethal for microbes. Funds will go to print 1,000 Drinkable Books and distribute them in Ghana, Haiti, India, and Kenya with water nonprofit Waterislife."

Our goals include: 1) Engage local communities in protecting and cleaning their drinking water. WATERisLIFE has ties to rural communities in Ghana, Haiti, Kenya, and India, where feedback from local folks in these communities will be gathered in Fall 2014 through Winter 2015. "WATERisLIFE is a big believer in "boots on the ground," according to founder Ken Surritte. So the books will go with teams traveling to parts of Africa and India, where they'll hold educational sessions on maintaining a clean water source."

2) Theresa will also explore other filter prototype designs to determine the best way to clean water with this pAge drinking paper technology. While in South Africa, Theresa worked with Corinne, a MS engineering student from Carnegie Mellon University. Corinne has led a group of students to design an emergency water filter using pAge filters. This new filter design also shows great potential, especially for emergency response and disaster relief applications! Initial field studies on this new filter prototype will start at the end of the summer 2014.

3) The number of books needed is many more than Theresa has ever made in the lab, and the production needs to be scaled up.
