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.
- spicybright 5y agoIt 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.
