Abstract
A wheel includes a tire, an electrical device requiring power for operation, and a conversion system for providing electrical energy for powering the electrical device. The electrical energy is obtained from conversion of a difference between pressure of a gas confined under pressure within the tire and ambient pressure of air outside the tire. The conversion system includes an inlet nozzle fluidly connected to the gas confined under pressure in the tire, an outlet nozzle fluidly connected to the air outside the tire, a movable arm configured to be moved by gas expanding while flowing from the inlet nozzle to the outlet nozzle, and an electromechanical transducer capable of converting mechanical energy from movement of the arm into electrical energy used to power the electrical device.
