Have you noticed the small crowd around the power outlets near the gates at most airports? What I see as a small community of people sharing a plug is a revenue opportunity for airports.
Technology Evangelist has a posting about the Smart Carte folks, who’ve built a system that will let aiports charge you $3 for 30 minutes of electricity.
You can go to the Air Power Wiki –

and get a list (sometimes even with photos) on free outlets at airports around the world. But the trend toward getting people to pay for power at airports is growing, I’m sorry to say.
