The Powerful, Remote-Controlled Electric Skateboards of Golden Gate Park

Sunday, February 8th, 2009

You see, this is why we have Healthy Sundays diverting cars away from JFK Jr. Drive in Golden Gate Park. It’s so people can zip along at 20 MPH on their .8 horsepower electric skateboards. You see what this fellow is holding? That’s his gas pedal, wirelessly connected to the motor. No embarrassing cord for him!

This could be you on your 2009 Altered Exkate Pro-Line 600. It’s only $600. Read the owner’s manual, read all the cautionary material, and skate, skate, skateboard.

Earth Hour Comes to San Francisco – Lights Out for One Hour.

Sunday, March 30th, 2008

After last night’s Earth Hour of partial darkness from 8:00-9:00 PM, the lights on the “architectural necklace” of the western span of the San Francisco-Oakland Bay Bridge came back to life on the north side first. (Unfortunately, didn’t get a look at the troubled eastern span last night – it was probably darkened also.) 

You can get the idea of the effect of Earth Hour 2008 in San Francisco by looking at these before and after shots of the Ferry Building taken by talented local photographer Mona Brooks.  

The lights on the suspension cables of the western span of one of the busiest bridges in the world are just for decoration, not for navigation safety or whatever. Pretty. They sure make a big difference to the look of San Francisco at night when they are turned off.

Question: Turning off these decorative lights for an hour saves enough electricity to power Al Gore’s house (his actual house, not his San Francisco condo in SOMA that’s visible on the right) for how many minutes?

Answer: About 13 minutes. Let’s work on that math, after the jump.
