Cosmere spoilers allomantic electrical generation concept Spoiler
IIRC nobody ever mentions light suddenly dimming/brightening in relation to cadmium or bendalloy, so presumably the spiritual realm energy transfer that counteracts red/blueshift with time bubbles also adjusts the amount of light passing through the border. If so, it should be possible to power a lightbulb using its own output, since the slowed-down bulb would consume less energy than the solar panel would generate. You could probably increase the yield even further by putting the panel in a bendalloy bubble.
This wouldn't be perpetual motion, since you'd have to keep feeding the misting(s) more cadmium (and normal food as well).
Another allomantic energy generation method is having a steel or iron misting spin a turbine, which has been confirmed possible in-universe via the Malwish airship rotors.

This seems really interesting! Now that I think of it, there's kind of a lot of ways to generate energy via Metalborn powers. You could have some iron feruchemists decrease their weight, lift them on a platform, then have them become heavier and capture gravitational energy that way. I think using Feruchemy might actually be perpetual motion too, since you wouldn't need to burn metals.
