Presto Pizzaz and Physics - Gizmodo

Gizmodo brought up a great point about the pizza cooker mentioned earlier also...

Since heat rises, that heating element underneath the pizza cooker's top section will lose a lot of its heat, and most of the heat coming from the bottom heating element will also be dissipated to the surrounding air. With summer coming up, this is a really dumb way to heat up your kitchen and make everyone miserable. Plus, that pizza sitting on there in the graphic above looks like somebody threw up on it.

LOL - didn't even think about the heat rising issue. I was too distracted by the stupidity of this single use device. (i wonder if you could bake a pie on it?) This 1,235-watt countertop oven space heater is sure to create some issues around it as well I just realized. How many fires due to some dumb-ass having a cookbook sitting next to it will this cause? The more I think about this thing, the dumber it becomes. via Gizmodo
