<p>A linear generator having adjacent coils spaced apart no more than approximately 6 millimeters, and a magnet that moves through the coils. The magnet has a height that is greater than a combined height of at least two of the coils. Preferably, a pair of series-connected coils are spaced apart a distance that equals the magnet height. Current induced in the series-connected coils is in phase. The generator may have a second magnet that is oriented to repel the first magnet and that moves at a slower speed than the first magnet. An electric energy storage device is preferably coupled with the coil and a battery charger that receives energy from the storage device when it reaches a charging level. The storage device preferably receives energy from the coil through a rectifier when a voltage level in the coil is greater than a voltage level in the storage device.</p> |
