Opportunities and challenges of long-distance high-capacity continuous wireless power transmission

Long-distance high-capacity continuous wireless power transmission(WPT) is one of the candidate routes to realize space-based solar power exploitation and carbon neutrality. Firstly, the application demands and development opportunities were introduced with specific technical requirements for practical applications of long-distance highcapacity continuous WPT. Secondly, the international state-of-the-art research progress was reported. Then technical challenges were discussed, with respect to development trend and application needs. And toward these challenges, development suggestions were proposed.
