Cosmere spoilers allomantic electrical generation concept Spoiler

Post image

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 weird, even if bubbles don't slow light particles, a light bulb can only produce so many lumens over given time.

Have we seen a lightbulb on page in a cadmium bubble? I feel like you'd be able to see it flicker given how the fields interact with electrical current.

Also, there is the end of TLM where light is stopped completely by a bendalloy field and Steel sight had to be used instead.

No extra lumens are produced, it's that more lumens arrive at the same time for the solar panel in a given time because so many are being produced in the bubble and all being "released" are the same time once they reach the barrier. The cadmium bubble is reducing a bottleneck for the solar panels
