Design goals for the MMRTG included ensuring a high degree of safety, optimizing power levels over a minimum lifetime of 14 years, and minimizing weight. [2] The MMRTG has a length of 66.83 cm (26.31 in), and without the fins it has a diameter of 26.59cm (10.47 in), while with the fins it has a diameter of 64.24cm (25.29).
NASA has developed a multi-mission radioisotope thermoelectric generator (MMRTG) in which the thermocouples would be made of skutterudite, a cobalt arsenide (CoAs 3), which can function with a smaller temperature difference than the current tellurium-based designs. This would mean that an otherwise similar RTG would generate 25% more power at ...

It would have produced 140 watts of electricity using a quarter of the plutonium an RTG or MMRTG needs. [11] The two finished units had these expected specifications: [12] ≥14-year lifetime; Nominal power: 130 W; Mass: 32 kg (71 lb) System efficiency: ≈ 26%; Total mass of plutonium-238-dioxide: 1.2 kg (2.6 lb)
The typical efficiency of TEGs is around 5–8%, although it can be higher. Older devices used bimetallic junctions and were bulky. More recent devices use highly doped semiconductors made from bismuth telluride (Bi 2 Te 3), lead telluride (PbTe), [10] calcium manganese oxide (Ca 2 Mn 3 O 8), [11] [12] or combinations thereof, [13] depending on application temperature.
