WED Fan writes "Scientists meeting in Stockholm are reporting that increased food and biofuel production will place higher demand upon irrigation and water resources." From the article: "Demand for irrigation -- which absorbs about 74 percent of all water used by people against 18 percent for hydro-power and other industrial uses and just 8 percent for households -- was likely to surge by 2050. Many nations are also shifting to produce biofuels -- from sugarcane, corn or wood -- as a less polluting alternative to fossil fuels. Oil prices at $75 a barrel and worries about global warming are driving the shift."
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
