Yes, that’s right, this is a concept sketch of the new infinite energy drive!
The great paradox, what happens when you attach buttered toast to the back of a cat? The forces of “cat always lands on feet” and “buttered toast always lands butter-side down” cancel out and the entire thing turns into an infinite energy drive capable of floating through space by canceling out gravity.
This new technology is used in flying saucers. Have you ever asked yourself “why do flying saucers humm?” The answer is simple, because inside they are loaded with purring buttered cats. As the flying saucer turns all the purring sounds like a plain ol’ humm. To control the vertical rise/fall of the saucer butter is removed/added to the back of each cat!
