You'd lose a lot of energy if it had to go through a table. And again, there's always the question of safety. I'm not sure so much free electricity will be healthy.
Back off topic...
To get slightly back on topic...
I believe I saw the article in an old Mobile Computing (www.mobilecomputing.com
) magazine; they don't offer the magazine anymore. They were good, since the magazine was free. No Sager ads, but when I was on a trip, I got a "LAPTOP" magazine and that's how I saw sager.
is a good article regarding power issues and alternative sources, If I can find the article about airport integration, I'll be sure to include it.
