One usually reads about Xenon or Mercury being used as fuel in ion-drives. What makes them adequate? I would prefer Nitrogen, as it is easilly found in the atmospheres of several planets. Can it be considered an adequate fuel? <div class="Discussion_UserSignature"> <p><em>“An error does not become a mistake until you refuse to correct it.” John F. Kennedy</em></p> </div>
