Scalable radioisotope power tiles

Scalable radioisotope power tiles that can provide heat, electrical power, or both, are disclosed. Unlike conventional radioisotope thermoelectric generator (RTG) designs, the scalable radioisotope power tiles do not necessarily seek to minimize the RTG surface area. Rather, a planar design may be used to maximize the radiative surface to increase the temperature difference (ΔT) and increase system heat to electricity conversion efficiency where electrical power generation is desired. In addition, such a planar design can be one-sided or two-sided, allowing for flexibility in design. For instance, such power tiles may be deployed in a material like a solar sail, on the surface of a vehicle, in terrestrial systems, etc.
