Water dowsing

What is water dowsing?

“Water dowsing” refers in general to the practice of using a forked stick, rod, pendulum, or similar device to locate underground water, minerals, or other hidden or lost substances,and has been a subject of discussion and controversy for hundreds, if not thousands, of years.

Although tools and methods vary widely, most dowsers (also called diviners or water witches) probably still use the traditional forked stick, which may come from a variety of trees, including the willow, peach, and witchhazel. Other dowsers may use keys, wire coathangers, pliers, wire rods, pendulums, or various kinds of elaborate boxes and electrical instruments. Далее

Water in the Middle East

Water security has always been an issue in the arid environment that characterizes most of the Middle East. Not until recently, however, has it been so serious. Although the Nile, Euphrates, Tigris and Jordan Rivers provide substantial agricultural, industrial and commercial support, the longevity of this scarce resource is being tested daily.

The rich landscape that was once referred to as the Fertile Crescent and the “breadbasket of the Roman Empire” is experiencing a variety of effects brought on by development and modernization. It is unclear what the future has in store, but what is certain, is that the politics of water is a turbulent issue that needs attention and support. Далее

The HydroPack Is Like a Capri Sun Pouch for Disaster Relief

Today is World Water Day. This year’s theme is “Water for Cities.” Yes, you can still attend all manner of walks, photo contests, screenings, and other events supporting global access to clean water. We’ve highlighted some noble projects for delivering drinking water in the past, but today we bring you you news of a new technology designed especially for disasters.

The HTI HydroPack is like an empty Capri Sun pouch with powdered nutrients inside. But it’s really a filter you can drop in any water source—a swimming pool, a mud puddle, a contaminated aquifer—and eight to twelve hours later the pack has filled itself with potable, fortified water. Далее

Water in Space: What Happens?

The Earth is one of those extremely rare, special places in the Universe where water can exist, stably, as a liquid. So much of it exists here on Earth, that if you were to add up all the oceans on Earth together, it would weigh more than 10^18 tonnes, more massive than the biggest asteroid ever, and about as massive as Pluto’s giant moon, Charon.


But water only has a very small window in which it can be a liquid. For instance, if you took some warm water up to a very high elevation, it would start to boil, and become a gas! The higher up you took it, the lower and lower your boiling point would be. Далее

Herschel Finds Oceans of Water in Disk of Nearby Star

PASADENA, Calif. — Using data from the Herschel Space Observatory, astronomers have detected for the first time cold water vapor enveloping a dusty disk around a young star. The findings suggest that this disk, which is poised to develop into a solar system, contains great quantities of water, suggesting that water-covered planets like Earth may be common in the universe. Herschel is a European Space Agency mission with important NASA contributions.

Scientists previously found warm water vapor in planet-forming disks close to a central star. Evidence for vast quantities of water extending out into the cooler, far reaches of disks where comets take shape had not been seen until now. The more water available in disks for icy comets to form, the greater the chances that large amounts eventually will reach new planets through impacts. Далее
