Grand Gestures, Hot Air and Cold Water

Who says that the issue of global warming is a matter of science, not faith? Just last week, Mayor Gavin Newsom proved belief trumps data. The Chronicle reported that a San Francisco Public Utilities Commission study found that the giant turbines he wanted to put underwater below the Golden Gate Bridge would cost way too much money to install and maintain. They would generate power at a cost of 80 cents to $1.40 per kilowatt hour — as opposed to Pacific Gas and Electric's 12 cents per hour commercial rate. It seems the turbines would produce only one or two megawatts of power — not the 38 megawatts Newsom envisioned.
