On behalf of all us, thanks for your work. Does the distance between the two surfaces at different temperatures matter? I'm sure this has occurred to you and your team, but the ambient temperature inside of a bedroom, beneath the roof, could provide a greater temperature differential.

Yes that distance matters in so far as getting the heat to the thermoelectric can be a bit more challenging. However I believe this has been investigated before and there are likely ways of doing it at least somewhat well.
