"With the Burning Man art festival in the Nevada desert starting Monday, a group of San Francisco scientists is busy calculating how much the event contributes to global warming."

"Encouraged by the resurgence of the green movement, the scientists are taking a hard look at all those sacred flaming temples, gas-powered scooters shaped like cupcakes, and hundreds of rumbling RVs that converge for a week on the dry Black Rock Desert lakebed." link

Oops! The San Francisco Chronicle article got it wrong. The "cupcakes" are NOT gas-powered; they're electric. Not to worry. The burners set them straight. See the link at the bottom.

What got into these scientists? I always thought the Burning Man participants were very conscientious. See Cooling Man.
