Niederwieser, Groll and Brendel can''t pinpoint which cooling technology makes for the best fridge, because it depends on the criteria that engineers are optimizing for. In terms of energy efficiency, vapor compression is the best bet. Niederwieser''s thermoelectric version has no moving parts or liquids, so he says his system is maintenance-free.
