An economic assessment of space solar power as a source of electricity for space-based activities

摘要

Those in the space community interested in deploying space solar power (SSP) need to know whether it would make economic sense. This article aims to develop a conceptual model of the economic value of SSP as a source of power to in-space activities, such as spacecraft and space stations. We offer several estimates of the value based on interviews and published data, discuss technological innovations that may compete with or be complementary to SSP, and consider alternative institutional arrangements for government and the private sector to provide SSP.
