A Real Iron Man Suit?

Is it possible that an Iron Man suit or something like it could exist in the near future?  That's what the US military is hoping and they have enlist the help of Hollywood to create it.

The U.S. has already spent millions of dollars to create a super suit which they have called the Tactical Assault Light Operator Suit (TALOS).  They have several companies working on the project and have now hired Legacy Effects-the people who created the suit in the Iron Man movies as well as other designs for blockbuster films to help them out.  With more money and time it is possible we may see a super suit some time in the future.

One of the biggest problems the military faces when creating the suit is how to power it.  Iron Man fans know that Stark's suit is powered by the Arc reactor.  That does not exist in our world unfortunately.  Therefore, the U.S. needs to find an alternate power source to operate such a massive suit.  

Another problem is the sheer weight of a suit. All of that material and metal will probably be very heavy.  Those working on the project say it could weigh as much as 400 pounds! No human can hold or operate that much weight.  This is another issue they are working to solve.  

The military has previously said they hope to get TALOS up and rolling by 2018.  With the problems listed above and actually designing the suit I am personally skeptical of this.  Not to mention, I am sure someone will complain about the suit for some reason.  I will admit it is an interesting thing to work on. What are your thoughts?  Is the super suit a good or bad idea? Not to mention is it even really possible?
