IMO the heat will mostly get out by your mouth/breath.
I like it. From a scientific POV I think the majority of the heat 'gets out' (of the load area) by chemistry/physics, at least we hope it does. That is the heat (in calories) is 'consumed' converting the good stuff to vapor so we can finally enjoy it.
Making vapor consumes heat energy, it gets no hotter (in degrees). Suck up too much heat (in calories) and the heat (in degrees) drops below the magic temperature and no more joy.
If you add heat to the load at a rate equal or less than that leaving through conduction through the walls vapor production stops even though you're still 'burning battery' adding heat.....it just doesn't get hot enough for magic time.
Anyway, I like it. I think we're all hoping the heat (in one form or another) gets to us.......
