Synopsis
Here is a summary of the key points from the paper:
- The paper discusses the potential for generating solar power in space and beaming it to Earth as a sustainable energy source. It was presented at the International Astronautical Congress 2023.
- Space-based solar power could provide constant and unlimited clean energy by collecting sunlight in space and transmitting it wirelessly to Earth.
- Key components of a space-based solar power system include the space segment (solar arrays, wireless power transmission), ground segment (receiving antenna), and launch systems.
- Major challenges include the high costs of launching to space and constructing large-scale structures in orbit. Recent advances in reusable rockets and lightweight materials could help address these.
- The paper proposes a roadmap with incremental demonstration missions, starting with small scale experiments on the ISS and building up to a full-scale pilot plant in the 2030s.
- Economic analyses suggest space-based solar power could become commercially viable in the long term if launch costs are lowered sufficiently. It has the potential to provide a significant portion of global energy demand.
- International cooperation will be important for developing space-based solar power given the large investments required. The paper recommends establishing an international agency to coordinate R&D efforts.
In summary, the paper provides an overview of the concept of space-based solar power, its potential benefits and challenges, and lays out a proposed development roadmap to make it a viable energy source for the future. While still early stage, it highlights the promise of space solar power to provide sustainable clean energy on a global scale.
