What if the answer to Earth’s energy crisis isn’t on Earth at all?
Space-Based Solar Power has lived in science fiction for decades. But now, with falling launch costs, autonomous robotics, and precision manufacturing, it’s moving closer to engineering reality.
Sanjay Vijendran, Director of Space Energy Insights and former European Space Agency lead on orbital solar, joins Mark and Jeremy to Think on Paper about what it would take to beam clean energy from orbit back down to Earth.
They talk wireless power transmission, lunar manufacturing, energy poverty, and whether space infrastructure can offer what terrestrial systems never could — a constant, global power supply.
If the sun is always shining in space, the real question is whether we’re ready to catch it.
Please enjoy the show. And share with a curious friend.
