It’s a great idea... our bodies run lots of systems - why not a flashlight... etc.

Not an invention, just a story that is catching on in the media because it has a girl in it. The peltier effect has been known since 1834, its not commonly used because its not efficient or effective in most cases. She might as well have strapped a solar panel to a flash light and called it an invention.

Perpetual motion machine: Strap a piece of buttered toast to a cat's back and drop from a 5-story building.
Making that scheme work requires an expensive carpet underneath to attract the buttered toast. Dropping the cat from shoulder height should be sufficient. :=)

Hmmm...have always thought the buttered side is self-seeking, regardless of the surface.
The drop height is to allow the cat-toast combo to achieve terminal velocity, and then convert same to angular velocity at a height above ground level of ~8-10”.
