An unpowered exoskeleton decreases the energy required for walking

[QUOTE=Smallheart;47476178]This is freaking rad, could be applied to lots of different venues to help people in need.

Sort of related, I went to high-school with a guy who's got a startup business going where he accepts scans of people's limbs and makes extremely affordable 3D-printed prosthetics. Most common prosthetics cost upwards of like $10k, he offers a flat rate of $300 for his. Really neat how technology is allowing more of these things to be accessible.[/QUOTE]

I guess that he isnt doing it for profit, but does he do this just for the help? If he isnt gaining any significant profit from this then he's a great guy.
