NASA space solar designs could slash battery use by 70% while boosting output

NASA's innovative space-based solar panel designs could transform Europe's energy future by generating power continuously in orbit. Two technologies - the efficient Heliostat Swarm and simpler Planar Array - could reduce battery storage needs by 70% while cutting grid costs by 7-15% by 2050. The continuous sunlight exposure in space makes these systems more efficient than Earth-based solar panels, though significant cost reductions and technological advancements are still needed for implementation.
