This sounds like an awesome step-forward! How would a space-based solar power system work? Proponents of the idea argue that the system would have all the benefits of terrestrial solar power – and that energy could be safely beamed back to Earth transmission stations 24 hours a day, seven days a week, rain or shine. Environmental and technical challenges still have to be met, however, including the challenge of building a network of energy-converting satellites in space. Click through this explainer to see how a space-based power transmission system might work.
