A fan assembly for creating an air current is described. The fan assembly includes a nozzle mounted on a base housing a device for creating an air flow through the nozzle. The nozzle includes an interior passage for receiving the air flow from the base, a mouth through which the air flow is emitted, the mouth being defined by facing surfaces of the nozzle, and spacers for spacing apart the facing surfaces of the nozzle.

Each blade has an airfoil shape to generate a torque about the axis responsive to wind across the blades. A support comprising cables under tension is connected between adjacent ones of the blades to extend generally circumferentially about the turbine. Accordingly a minimum number of parts form the structure of the blades while minimizing the drag produced during rotation thereof due to the support members lying in a common circumferential path. The tension of the support members can support the blades in a pre-stressed condition to optimize the shape and performance thereof.

A resulting thermoelectric voltage (Vout) of the thermopile (7,8) is divided by the power to provide the responsivity of the sensor.

Application of carbon fiber reinforced polymer structures to metal vehicle wheels is effective in reducing the mass of the wheel while retaining suitable stiffness in the wheel structure. For maximum effect the reinforced polymer structure and the metal wheel must operate cooperatively. Because of the wide range of operating temperatures experienced by wheels and the large difference in coefficient of thermal expansion between metals and carbon fiber reinforced composites attachment of the polymer structure to the wheel by adhesive alone is problematical. However a wheel with an effective and durable reinforcement may be fabricated by confining, through mechanical interference, the reinforced polymer in a cavity in or on the spoke and by preheating the wheel before curing the polymer.
