Imagine a water transistor—a device that allows water to flow between two points only when a specific water pressure is applied at the base. This transistor operates without any electrical components or mechanical springs, relying solely on principles of fluid mechanics. Is it possible? If so, how can it be designed?
- The system must be binary: either fully open or fully closed—no intermediate state.
- The transition between states must depend solely on water pressure applied at a specific point (the base).
- No electrical components or springs should be used to trigger the state change.
