A company is actually working on a suit that can give its wearer super human strength. It's a metal and hydraulic robotic shell that makes everything lighter. For every one pound the person inside exerts -- the suit exerts 17-pounds.
The suit is not ready for use in the field because of one big obstacle: how to power it. Right now, it runs on an external power source because the batteries would be too dangerous in combat situations. But the suit could be very useful for supply units that move heavy loads -- where being tethered to a power source wouldn't matter.
If all goes as planned, the company hopes to see the $150,000 'Iron Man' suits deployed in the field by 2015.
