Re: New suits are a necessity
"the word "nano" was not used by NASA, considering the weight concerns, maybe Z-3 will not be the final version."
I believe there were many versions between this prototype and the final version. And that final version will be very different from the one in these pictures we see today.
As you said, nanotechnology can't be left out. IBM even created a 3D nano printer. Just imagine all the new things, materials, and technologies that will be available by when it's really time to think seriously about the this suit. This time it was just a teaser to entertain the masses.
