I probably have posted on the electricity generating speed bump more times than it deserves, but Glen Reynolds linked this story and I am seeing it linked uncritically all over.  Here was the email I dashed off to Instapundit:

The speed bump / power device at the Burger King in New Jersey is the silliest technology I have ever seen and I am amazed that so many people praise it or write uncritically that it provides free power.  Energy is never free, it comes from somewhere.  In this case, the energy is actually stolen from the car.  The electricity power produced is equal to or less than the extra power the car has to expend going over the bump.

This electricity might be "free" if it is used where cars are braking anyway, say on a long down ramp in a parking garage, or on a suburban street or school zone where speed bumps already exist.  But the Burger King example, and in fact most of the examples I have seen of this installation, are just vampiric theft, very similar to what the US Government does in many of its programs, creating a large benefit for a single user and hoping that distributing the costs in small chunks across a wide number of people makes these costs invisible.

I wrote more about the technology here.

Gee, why isn't the Congress doing something about this price gouging in a scarce commodity post-Katrina?

Burger King is offering a $6,000 signing bonus to anyone who agrees to work for
a year at one of its New Orleans outlets. Rally's, a local restaurant chain, has
nearly doubled its pay for new employees to $10 an hour...

On any given day, contractors and business owners pass out flyers in
downtown New Orleans promising $17 to $20 an hour, plus benefits, for people
willing to swing a sledgehammer or cart away stinking debris from homes and
businesses devastated by Hurricane Katrina ...

"I'd say I'm paying two to three times as much as I would in normal
circumstances," said Iggie Perrin, the president of Southern Electronics, a
supplier in New Orleans, who has offered as much as $30 an hour when seeking
salvage workers on Canal Street...
