Looking forward to it.

I mean hey, maybe it is a dumb idea, but I've always felt that the
dumbest question is the one unasked.

And at least now I know that, indeed, ten watts per fiber isn't
unreasonable. I suppose that a decade of research could always help
reduce losses and such. Are the fibers used in communications
different than the ones you are using? Do they use some special
ingredient that makes it impractical to manufacture them in space?
