Power Beaming System
Power is needed for everything and effective delivery over 10's of thousands of kilometers is not easy. Various methods were examined and laser power beaming was selected for the baseline. This is a mature yet still rapidly evolving technology.
|Power input||20 - 150||MW|
|Power in laser beam||2 - 15||MW|
|Primary Beam diameter||10-30||meters|
|Power source||Solid-state disk laser|
Boeing has demonstrated operation of a 25kW laser of teh kind we need and claim they can build MW lasers Beaming 9+kW lasers over short distances are being demonstrated at the Spaceward Space Elevator Games Adaptive optics have demonstrated long distance capabilities Include images and videos from the SE Games Include design write-ups
Delivering power over the distance of the elevator is a challenge but quickly being addressed by current technology.
