Attorney, Agent or Firm: Ladas & Parry

A power apparatus in which a battery is connected to a dynamo to drive it as a motor and deliver energy to a spiral spring to wind-up the spring. When the spring has been wound to a particular degree a sensor disconnects the motor from the spring which now unwinds and delivers output power. A further sensor detects low charge state of the battery and during unwinding of the spring, some spring energy is delivered to the dynamo, now acting as an alternator, to charge the battery.

DETAILED DESCRIPTION The scope of the present invention is to provide a power apparatus in which, in spite of extremely limited consumption, the developed power is surprisingly high.
