If you place a argon lasar in stationary orbit above the earth and then 
aim it toward a parabolic dish which is attached to a ship in space, can 
the lasar propell the ship? would you need to maybe inject air into the 
dish? I know that this has been done here on earth, but in a small scale. 
Thank you for your knowledge ahead of time. Chris
