This is not the case. Moving around a 100-kg suit should be roughly the
maximum power output of a human (E.g. doing this by your self would be
the most one could do, but not impossible. Note I said power NOT
force.) Using this as a guess as to power requirments, this implies a 2
kW, or roughly 3 horsepower output. Allowing for efficiencies, I can't
see such a suit requiring more than 10 hp. Are you saying that a 10 hp
motor is too big?
