If you want to talk about heat transfer you must necessarily talk about temperatures, and there's not any mention on that article.
The thing with heat is that it has a "quality" and the low T of the ASIC's makes it hardly usable in anything other than space heating in very cold places. As they mention the T diff. is the main point. You need at least 10 or 20ºC difference in order to transfer it something efficiently, so if you have heat at say 90ºC you can only heat something to 70ºC or so, but those are not industrial applications.
