Space-Based Solar Power: Addressing Fundamental Challenges towards Practical Implementation

Wireless energy transfer Wireless energy transfer encompasses a wide range of technologies and applications. In this paper, the focus will be on space-based solar power (SBSP), which refers to the process of harvesting energy from space using solar panels and then beaming the energy to Earth. While each component of the SSPT is fully understood from the theoretical point of view, here, we focus on some challenges that need to be addressed before the SBSP becomes commercially feasible. Specifically, we address two challenges: transmission efficiency of the transmitting antennas, and the absorption efficiency of the receiving antennas.
