| Sep 1, 2023 at 21:26 | comment | added | Gault Drakkor | @ChristopherJamesHuff I fully acknowledge commercial piezoelectric exist. What doesn't exist is a good way a recipe to use them to power devices that need non trivial amounts of energy continuous. a watch is probably low enough energy to not have been a good example. something that requires more energy like beyond 100mA like a wifi module plus some other stuff is more what I am saying can't be powered by current off the shelf piezoelectric without a fair bit of work | |

| Sep 1, 2023 at 17:30 | comment | added | Nuclear Hoagie | @KeizerHarm Piezoelectric materials work by slight deformation. Every footfall will generate a small amount of electricity, but will be slightly more tiring as the ground gives underfoot - in principle, it'll be like walking on sand, although much less pronounced. | |

| Sep 1, 2023 at 9:34 | comment | added | Cadence | Horses (or whatever) are also pretty inefficient engines when you come down to it. Leaving aside all the care they require, I suspect you could generate more useful power by burning their feed directly. | |

| Sep 1, 2023 at 3:18 | comment | added | Christopher James Huff | @GaultDrakkor piezoelectric energy harvesters are off-the-shelf technology now. They're just used for things like powering simple, low-power remote sensors, not for running strength-augmenting powered exoskeletons. | |
| Aug 31, 2023 at 23:29 | comment | added | Gault Drakkor | At this time there is no recipe for piezoelectrics to be generating electricity for use. ie its future tech. to say that it can power a watch is hypothetical. | |
| Aug 31, 2023 at 23:15 | comment | added | Christopher James Huff | If the devices were constructed to generate significant power, yes, they would be quite exhausting. This would be something that compresses with resistance but provides no restorative "spring", sapping energy that would otherwise be stored temporarily in tendons and muscles. It would be similar to walking in soft sand. | |

| Aug 31, 2023 at 21:21 | comment | added | Coquí | Was that one animal powering one electronic watch? I'm wondering what dozens or a hundred do if they were all hooked together. Lol maybe refrigerator, a radio, and a loudspeaker playing so the donkey driver can be an ice cream man on the the side | |
| Aug 31, 2023 at 21:17 | comment | added | AlexP | @KeizerHarm: If the generators generate significant amounts of power, that power must come from somewhere. If the power generated is small enough as to be irrelevant to the animal, it is irrelevant. Practical example: have you ever used one of those foot-actuated pumps for inflating inflatable things? (And force is not energy. Force times distance is energy. It's one thing for the animal to just put its foot on the ground, it is a very different thing if the poor beast has to press down for some distance in order to power a generator.) | |
| Aug 31, 2023 at 21:13 | comment | added | KeizerHarm | @AlexP The energy that piezoelectric horseshoes would generate, is the force of the hooves hitting the ground. That energy would otherwise have been converted to heat and wasted. It wouldn't tire the animal out to wear them, unless the device was much heavier. That said I agree it wouldn't generate all that much. | |
| Aug 31, 2023 at 21:12 | comment | added | AlexP | P.S. Powered exoskeletons are the antithesis of low tech. We with 21st century technology cannot make a useful powered exoskeleton unless with grteat cost for extremely specialized applications, such as working very deep underwater, where no other practicable solution exists. | |
| Aug 31, 2023 at 21:07 | comment | added | AlexP | Any energy which might be generated by any kind of electrical generator powered by the movement of the animal comes from the animal, and thus reduces its strength and endurance. There is no free lunch. (But the good news is that piezo generators are extremely low power, so that the animal won't feel much of anything. The low power might be enough to power some sort of electronic watch.) | |
