Laser Launch Vs. Space Elevator?

[nexium]

Eniac is correct . The new 12 meters is for a smaller spot size than the climber needs. If I recal correctly 50 kw is needed for the one ton climber, so 5 megawatts should be enough for the 100 ton climber, if one that massive is ever built. There is a reference thread at www.liftport.com with lots of mostly correct details. Click on forum near the bottom of the home page. Neil
