About the "superman suit" thing.
Actually, there currently are strength-augmentation suits in use by construction companies. Admittedly, these things are still slow and bulky, but they get the job done. I think a much sooner and probable application could be for the robotic dog that the US Army is researching to carry soldiers' gear into battle. With miniaturization of control circuits, and maybe some adaptive neural nets thrown in there, and you've got yourself a personal transport than run across rough terrain. (Of course, I still don't know why the Army picked a dog as the basis for the design. Why not an insect or a crustacean? Maybe it's that "Man's best friend" psychology.)
I think I read somewhere that artificial muscles have been incorporated into prosthetics before, though those were liquid-based. If this technology actually has the reliability, durability, fast reaction times, and controllability necessary for a better prosthesis, it'll sell like hotcakes.
P.S. - the news link doesn't work.
P.P.S. - Another idea: search-and-rescue robots. Imagine a search-and-rescue centipede or snake. That'd be SO much better than a search-and-rescue mini-Abrams.
