Abstract: A wind driven electricity generator may have a tower with a set of stationary airfoils mounted thereon. Each airfoil may have a slot on a low pressure side of the airfoil. Air flow may through the slot relative to an inside of the airfoil. Air flowing through the airfoil may flow through the tower. The air flowing through the tower may turn a rotor (or propeller). The rotor may turn an electrical generator to generate electricity. Each airfoil may have a slot on a high pressure side. Air flowing through the slot on the high pressure side may turn the rotor.

Abstract: A motorcycle helmet that includes one or more white light type beam forming LEDs (LEDs with lenses that form a beam) mounted in the front of the helmet, such as the helmet forehead area. The LEDs may function as a headlight that may supplement the motorcycle headlight. The beam(s) projected by the LEDS can be steered or aimed at an object by the helmet wearer and may help the rider and motorcycle be more visible to oncoming vehicles or vehicles entering from a side road while at the same time having a downward pointing aspect and a power hat does not create glare for other drivers. The LEDS may be in a self contained module mounted on the outside of the helmet. The LEDs may be mounted or embedded in the outer shell of the helmet with the batteries and electronics being inside the shell and within the foam type compressible inner shell. The batteries and electronics may also be within the helmet neck roll near the bottom rim of the helmet.
