1) At the frequencies you envisage using, wouldn't the heat have difficulty entering/leaving the material? IOW wouldn't you just end up recycling the same heat over and over again internally? (A thermal "short circuit" as it were?) 2) If the temperature difference is just a couple of degrees, doesn't the Carnot limit severely restrict the potential efficiency of any conversion device? 3) I thought that magnetic cooling was already widely used, and am not aware of any OU associated with it.
