Instead of all the heat concentrating in your palm, it is now distributed around the entire case.

Great! Now I can heat both palms!

I glanced at an article in the latest BusinessWeek about Dell's new laptop. It's nice to see Apple putting the fear of God into these bigshots.

ought to make it 1/4 as hot as before...


25%? Can't wait to see the math on that one Perfesser.

"Heat" is an energy transfer which takes place when two regions of different temperatures are connected by a thermal conductor. You're suggesting, I suppose, that this conductor is now the metal casing of the device. "Why do I need a radiator in my car when I see plenty of motorcycles riding around without one." Because the engine in your car doesn't have nearly enough surface area to dissipitate the heat.

This is where Mark Palmberg's griddle idea begins to make a lot of sense.

The second law of thermodynamics states (in part) that "heat, on its own accord, flows from regions of high temperatures to regions of lower temperature". Water is a much better conductor of heat than air. If you're holding the heat emitting device, the "thermal conductor" is your unfortunate hand. This isn't rocket science, kid -- just high school physics.
