Kotatsu vs. SunRay
By davidleetodd on Aug 22, 2007
I've been working at home this summer, and it has been hot. We try not to run the air conditioner too much, out of ecological guilt. This afternoon I was really sweating, and had to put the air on in the room where I work. BW was kidding me gently about the room where she was not feeling warm at all, and suggesting that maybe my overeating at lunch was making me sweat.
Later, I had to call one of my colleagues up in the Bay Area, and while I was complaining to her about the heat, I began to realize that most of the heat in the room was emanating from my laptop. It was actually quite painfully hot in some spots. I told her about it, and she smugly replied that her SunRay draws very little current, and thus is quite cool. This is what happens when you complain to a female engineer.
Anyhow, she got me thinking about my laptop's excessive power consumption, and the heat it throws. I started looking at it closely, and it appears that the heat is vented to the front, directly under my chin, whence it rises to bathe my face in extra warmth on a hot day. Gaahh!
It occurred to me that in the winter this would be quite pleasant, rather like a kotatsu, the Japanese combination of card table, heat lamp and quilt that my sister had told me about. She goes to Japan every year, and is quite fond of the communal kotatsu, where everyone gathers in the winter to play cards, talk and stay warm in poorly heated Japanese houses. So I guess I should switch to a SunRay in the summer, and save my laptop to serve as a kotatsu in the winter. Might save on the heating bill, but it lacks the conviviality that a true kotatsu would provide.
