Seems that configuration can only assist/augment the buttocks muscles? Doesn’t seem to be a way for it to assist the hamstrings and calves, let alone the feet for stability and balance, i.e. the entire chain of muscles working in concert. E.g. suppose my calves get tired first – this exoskeleton doesn’t seem like it could help.
Bit off loss is fine, esp if it’s storing extra “free” renewable energy that would otherwise just be thrown away/not collected
I think article directly emphasizes the hope that it’s sustainable, scalable, and available. For example, pumped hydroelectric isn’t as available because it needs just the right terrain of two nearby lakes separated by as much elevation as possible
