Partly due to WB's great response to my steampunk questions, I think the world I'll work on next will have to be steampunk :)
If I had a steampunk cyborg running around, what could he do with his arm? I'll take care of maintenance myself; don't worry about that. I'm more interested in the possibilities of how much he could lift etc, if this arm was running just on steam-power.
Obviously, since this doesn't have to really work (and I doubt it really would), I can certainly stretch things a bit (and probably will), but I'd like to have a ballpark figure for lift power in this arm -- most specifically, if it'd be more or less than human strength; with regards to my story, the question is whether an undercover cyborg can be detected easily from the strength of his arm alone.
How strong would a steam-powered prosthetic arm be?
To make things easier, assume that a knapsack is available to be used for extra steam-power hardware; like water tanks and such, in case it can't be done with everything inside the arm. I'd much prefer not to need to knapsack, but it's not completely out of the question.
