Could Solar Panels in Space Solve all Our Energy Needs?

The video discusses the increasing global energy demand and the limitations of current solar panel technology on Earth. It explores the concept of space-based solar power, initially a sci-fi idea, and the potential of using satellites to collect solar energy. Two main methods are considered: microwave energy transmission from geosynchronous orbits and laser-powered satellites in low Earth orbit. While both have challenges, such as cost and technical hurdles, they offer promising solutions. Current efforts by countries like the US, UK, and Japan are highlighted, indicating a future where space-based solar power could become a reality.
