"The 72-couple device exhibited the highest reported output power and device power density from a single thermoelectric generator... scientists placed six couples along a thin strip. They then used flexible metal foil to connect 12 of the strips together... Liquid metal was used between the layers of each strip to improve device performance... 3-inches squared, maintained a 115% power density advantage. That version exhibited a total power output of 56.6 watts"
