water (Page 11)

One of the biggest problems facing the world in the future will be getting enough water. If we could just think of a way to remove the salt from the ocean, we would be surrounded by drinking water. Lots of scientists would like to figure out how to do just that. Now the inventor of the Segway says he has invented a machine that can take nearly any source of moisture?even ocean water, urine or sewage?and quickly turn it into safe drinking water.

Scientists in Australia, which despite being surrounded by water, is having a major drought, want to use solar power to run desalinization plants, in order to avoid the additional problem of greenhouse gas emissions, since many of these are given off by power plants that create electricity.

Even Better: Reading Your MIND – New kinds of lie detectors are being developed all the time?the latest one is your hair. And no, we don’t mean whether or not you dye or perm, we mean your hair can tell an investigator where you’ve BEEN. It all has to do with the water you’ve been drinking. These days, almost everyone seems to be carrying a bottle of water around with them, but it turns out we don’t need to drink as much water as they’ve been TELLING us we do. Recent findings indicate that most people do not need to worry about drinking their recommended 8 glasses of water per day. While it is clear that humans cannot survive for longer than several days without water, very little research has assessed how average individuals’ health is affected by drinking extra fluids.read more

Too much salt isn’t good for us, which is why researchers are working so hard to figure out how to remove it from water so we can drink the water from our oceans. Salt has gotten a bad reputation, since doctors warn us it can lead to high blood pressure. But other scientists say that, just like corn-fed beef, the problem isn’t the salt itself, it’s our modern version of it. Salt isn’t necessarily bad?if you know the difference between good and bad salt.
