The question they don't address is what the relative cost of these thermoelectric cells is. I'll grant that they're still in prototype phase, but some mention of the estimates of cost would be nice. I, for one, have no idea how much bismuth telluride costs.

I guess for some kind of comparison: Copper is $0.008 per gram. Potassium (pure) is $1.50 per gram Magnesium is a few cents per gram

You can put these panels under your solar water heater and get slightly hotter water with an additional trickle of electricity into your home. Maybe you could power a pair of USB heated gloves.
