Iron Man Mark 1/2 Armor

That's right, defense contractor Raytheon Sarcos in Salt Lake City has demonstrated, what could best be described as a prototype exo-skeleton.  In the video, the "pilot" performs a few feats of strength.  Punching through 3 inches of pine and doing pushups with heavy weight on the pilot's back (not including the weight of the skeleton.

A hightlight in the article, which probably explains the suit's more practical use, is that it gives its pilot 17 times more strength and could be used to lift heavy supplies.  I'd say that puts it more in line with Ripley's power loader from Aliens

Now, here's the real surprise.  The estimated cost will be only $150K.  I think Tony Stark paid a bit more for his.
