This ingenious prototype device will serve two main purposes:
1. It contains the feline fleshbag behind a plexiglas shield, effectively incarcerating it for life in a secured container. In doing so, it will never be able to claw another human being, steal valuable resources, or participate in the upcoming revolution in which cats will kill untold amounts of humans.
2. It will provide a cheap source of power to third world nations. By picking up cats on the street (or hell, stealing them from pet owners) and putting them to work in the device, you help clean up the stray trash and are rewarded with clean, cheap energy with essentially no pollutants or harmful byproducts.
Finally, there is an additional benefit that accompanies point 2. When the cat is no longer able to continue working or otherwise ceases to live, the cat can be used as a food source to feed the starving. No part of the feline fleshbag will go unused, just as God intended.
