How much electricity does this contraption need to generate, before it's accounted for its own embodied energy (that is, the power needed to manufacture it)? Probably more than anyone would ever actually use one.
It reminds me of solar panels on cars. It sounds great if you don't think too hard about it, but a highschool physics course can easily prove how completely useless it would be in practice.
Ideas like these end up being nothing but virtue signaling, whether people know it or not.
Practically all of our "green" solutions rely on the fact that their energy-intensive manufacturing is done somewhere with lots of cheap (and polluting) energy sources.
Show me a wind-powered lithium battery factory and I'll change my mind.
