Abstract
A spring operated generator includes a pair of torsion spring banks and a pair of elongate shafts extending through respective spring banks and operatively connected to respective generators. A starter motor is connected to each respective spring bank for initially winding each spring bank. When actuated, the primed spring bank is allowed to unwind. A clutch coupled to the elongate shaft is configured to engage a respective generator, transferring energy from shaft rotation to the generator which produces electricity. As one spring bank unwinds, the other spring bank is wound in like manner as the first. When the initial spring bank is unwound and the other spring bank is sufficiently wound, the cycle is repeated, thereby causing the other generator to produce electricity.
