no launch from ground, no atmospheric interference
I've thought of a way to concentrate a laser-the only thing I am uncertain about is how to effieciently distribute an extremely powerful laser over a photo voltaic array. perhaps we could assemble a decahedron out of GaAs panels.
the risk of hitting vulnerable components would be a concern so you would want to tie your laser power collected off at a reasonable distance from the space craft-and you would want to have mutliple mechanical fail-safes to make sure the servo controlling the aim of the laser does not go beyond a certain distance from your collector.
