Researchers investigated the hidden costs of water use by estimating the amount of H20 consumed per U.S. dollar of end product by different industrial sectors, including agriculture.For instance, it takes about 270 gallons 1,022 liters of water to produce a dollar’s worth of sugar, about 200 gallons 757 liters to make a dollar’s worth of pet food, and 140 gallons 530 liters to make a dollar’s worth of milk.

Is There Ice on the Moon?

Could there be ice on the moon?

A team of British researchers thinks so, and theorizes that the water could be put to use by residents of a future permanent lunar base.

Poring over data from NASA’s 1998 Lunar Prospector probe, the Durham University scientists found that hydrogen on the moon tends to be concentrated in dark craters near the lunar poles — exactly where you’d expect water, permanently shielded from the sun’s rays by the crater walls, to stay frozen.

Can You Die From Drinking Too Much Water?

In January 2007, hours after competing in a radio station contest to win a Nintendo Wii, 28-year-old Jennifer Strange was found dead in her California home. The station’s “Hold Your Wee for a Wii” challenge awarded the game system to the contestant who could drink the most water without having to take a trip to the bathroom.

According to preliminary autopsy reports, Ms. Strange apparently died from drinking too much water too quickly, resulting in a condition called water intoxication.


How Much Does a Cloud Weigh?

“Let’s start with a very simple white puffy cloud – a cumulus cloud. How much does the water in a cumulus cloud weigh?

Peggy LeMone, senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, did the numbers. “The water in the little cloud weighs about 550 tons,” she calculates. “Or if you want to convert it to something that might be a little more meaningful think of elephants.”
