Motivation: Addressed $90B U.S. frozen pipe problem.

Concept: Thermal wax actuator triggers flow release in freezing conditions.

Design: No power, modular retrofitting, manufacturable by injection molding.

Testing: Cold chamber trials at -7°C, COMSOL simulations.

Market Validation: Feedback from local plumbers & hardware stores.

Recognition: $1,000 Entrepreneurial Grant + VC interest.

Outcome: Fully functional MVP with strong scalability.
