...does it work? Air conditioning relies on some form of heat exchange. In this case, it's a thermochemical one between water and salt that takes place in a vacuum. Water evaporating from a tank inside ClimateWell's refrigerator-size unit is absorbed by salt housed in a connected tank the water molecules can't resist sticking to the salt, turning it into a slurry. As water evaporates, it gives up energy, which is then released inside the salt tank. The result of the energy transfer: the water becomes colder as the salt heats up. Pipe water through the slurry...
...concern for his own safety and desire to live to a ripe old age, his feelings of responsibility for a toddler with him in a car seat, the cost of banging up his shiny new car or losing his license.

It is this very human context in which risk exists that is key, says Adams, who titled one of his recent blogs: "What kills you matters - not numbers." Our reactions to risk very much depend on the degree to which it is voluntary (scuba diving), unavoidable (public transit) or imposed (air quality), the degree to which we feel we are in control (driving...
...They want some competing data points and information streams," the adviser said. "They don't want the Baker commission to be the only vehicle for filling the vacuum." People who have been consulted by the commission say it appears to be headed toward recommending greater U.S. engagement with Iran and Syria on the Iraq situation, and some modest increase in troops - perhaps 20,000 to 25,000 - to speed up training of Iraqi security forces. Vice President Cheney, among others in the White House, is prepared to fight the recommendation about Iran and Syria. "He's against engagement with Iran...
...This is an invitation to look foolish, as with the predictions of doomed cities and nuclear-powered vacuum cleaners that were made 50 years ago,” he said in the survey...
