  This paper presents a new and innovative design for scaleable space solar
power systems based on satellite self-assembly and microwave spatial power
combination. Lower system cost of utility-scale space solar power is achieved
by independence of yet-to-be-built in-space assembly and transportation
infrastructure. Using current and expected near-term technology, this study
explores a design for near-term space solar power low-Earth orbit demonstrators
and for mid-term utility-scale power plants in geosynchronous Laplace plane
orbits. High-level economic considerations in the context of current and
expected future launch costs are given as well.
