A satellite in orbit that needs to point in various directions (e.g. a telescope) can use reaction jets powered by a stored compressed gas supply. The problem is that once the gas is exhausted, the satellite is no longer useful; refueling is seldom mechanically or economically possible.Quote:

My first thought was use as a self-balancing mechanism in an exo-skeleton suit for paralyzed folk. I saw a TV pilot deeecades ago called 'Exo-Man', about a paralyzed scientist who did just that and went out to do superhero crime-stoppery stuff.Quote:
