Imagine capturing the sun’s energy not on the Earth’s surface under ever-changing skies, but high above the clouds, in the endless sunlight of space. This is the exciting promise of Space-Based Solar Power (SBSP). SBSP refers to a technology concept that collects solar energy in orbit using satellites or large orbital structures , converts this energy into electricity, and sends it wirelessly down to Earth-based receivers . Unlike ground-based solar panels, SBSP systems are not limited by nightfall, weather changes, or atmospheric interference, offering a continuous stream of clean, renewable energy anytime, anywhere. Historical Background The idea of harnessing solar energy from space is not new. It was first proposed by the Russian scientist Konstantin Tsiolkovsky in the early 20th century, who is known as one of the founding fathers of astronautics. Later, in 1968, American engineer Peter Glaser advanced the concept by designing and patenting a solar power satellite system. NASA ...
