Does an unpowered clutch engage a spring in parallel with the Achilles tendon when the foot is on the ground, offloading the calf muscles and making walking easier?

Yes, when walking with a passive-elastic ankle exoskeleton.

Earlier quoted context omitted.

That's... exactly what the caption under the first image says.

He's mocking the article, which repeats that caption on every picture.

The problem is, the linked "article" is not the article.

This is the article: https://www.nsf.gov/news/news_summ.jsp?org=NSF&cntn_id=13466...

"Download the high resolution of the image"

Unfortunately, the "high" resolution only holds for the x and y dimensions, not the t dimension.

Though what we really need is a device to decrease the efficiency of human walking.

That is already a mature technology. I prefer to use a heavy pack but cell phones are also a popular technique.

There's an even simpler device -- the string. Simply tie your ankles together and presto.

I've studied a number of martial arts and body work disciplines. One thing we did was teach people is to walk more efficiently - it's not hard given that the average person just follows the example of their peers and then allows habitual muscle tension to gradually interfere.

The thing about this device is I suspect that even if did work, it would just allow people to just further lower their level of coordination and ultimately have rather poor health results.
