We are obsessed with the oil crisis. So much so that we fail to see other problems that face us in the near future. For example, what about fresh drinking water. If nothing is done soon, the world will be in crisis. Even countries with cold climates, in Europe, are facing a shortage of potable water because of the high population density. As people become Westernized they consume more water. They change from bathing when they can, to having showers every day.

Production oil also impacts on the availability of water. it takes 2.5 liters of water to produce every liter of oil. Even growing bio fuels puts pressure on water, with a thousand liters of water needed to make a liter of bio fuel. The modern way of life is water "heavy":

Wealthy people use 3,000 liters of water each day to live their lives. More drought in the world is putting prices of everything up. When water gets short it does so locally. Moving water from one place to another in bulk is problematical. In the short term it is possible, but in the longer term it is not. Food production will fall behind what is needed over the next two decades if nothing is done.

The oil crisis and carbon pollution are problems but a shortage of water will hurt most of all.

The Science of Carrying a Mug of Coffee

You wouldn't think that finding out how to carry a mug of coffee without spilling it would be a subject for analysis by scientists, but you would be wrong. Rouslan Krechnetnikov took it upon himself to solve this disruptive daily issue.

This area of study dawned upon him when he watched people struggling with mugs of coffee at a fluid dynamics conference. He thought that the solution wasn't simple. It was a complex scientific problem. The coffee carriers gender, age and health would affect the solution.

Tests included walking in a straight line with coffee in hand while looking at the mug or looking ahead. A sensor in the mug measured spillage of coffee. Conclusions were that one should walk slower and, wait for it - watch the mug not where you are going.

This sounds like advice leading one to disaster. "Watch your heads and laps everybody someone's coming who doesn't know where he's going! Why don't you get a cup you fool?"
