Re: Solar powered lasers in space

Just one point. Could you explain why you would prefer a 4 wave mixing
system to a straight computational system? You mentioned earlier
safety considerations, but is that really true? If someone were to
shine a laser upwards they would get roasted. This would in fact
constitute a powerful weapon.

A computational system would be required to ensure that this did not
happen. Why not have a straight computer system and build safeguards
into the software. In fact what you will have is a computer network
with (possibly) one 8 bit computer controling a laser.

Sites on the ground will ask for power. Air/space craft will give
their positions, velocities and accelerations using GPS/Galileo and
also request power.

The main advantage of a straight computer is that the whole thing is
easilt simulatable on the ground.
