I recently looked into them and was put off by the price. So I bought a Cubii, which is an under desk elliptical. I’m only a few days in but so far it’s been so

I recently looked into them and was put off by the price. So I bought a Cubii, which is an under desk elliptical. I’m only a few days in but so far it’s been solid.

Funny enough, I've only ever seen these advertised at the gym I used to work out at (pre-Covid19), on the TVs people watch while riding the exercise bikes. They'd certainly be more effective than that spinny squirmy chair gizmo, although that one might be good for posture. I still think these things should be rigged up to charge cell phones and whatnot. Lots of unharnessed energy released in exercise.

    Ah, there are two ways to understand what I meant. I wasn't talking about human efficiency (which it does sound like I might have been), but about the unused mechanical energy. In most exercise machinery, there is an energy output that isn't being harnessed as much as it could be. Some stationary bikes and rowing machines use the person's pedaling or rowing to power the controls, so there is an example of where it is being used. But the majority of other pieces of equipment are not harnessing the energy output. For example, every one of the pulley machines could have a magnetic shield around a segment of the (metallic) cable, which would produce a current both on the pull and on the release from the person exercising, without adding any noticeable tension. Another example of where potentially harvestable energy isn't being used: although the chain on the rowing machine is often used to power the screen, the seat could also be used to generate electricity as it glides back and forth, using the same magnet concept.
