i believe you - the photon drive is an sf staple. if i have my figuring
right, the force you get is the power output divided by the speed of
light. you know, i never did this much physics at school - perhaps Ft
SF) should be be put on the national curriculum?

erm ... i'll have take your word for that :-).
