A human-powered generator includes a frame and a pedal crankset and crankset sprocket rotatably mounted on the frame, a flywheel rotatably mounted on the frame including a flywheel-crankset sprocket a flywheel-countershaft sprocket, a countershaft rotatably mounted on the frame including a countershaft-flywheel sprocket and a countershaft-alternator sprocket, and an alternator including an alternator drive shaft and an alternator sprocket. The human-powered generator also includes a crankset-flywheel drive chain, a flywheel-countershaft drive chain, and a countershaft-alternator drive chain. A pedaling cadence at the pedal crankset of between approximately 60 RPM and approximately 100 RPM achieves an alternator drive shaft RPM of between approximately 2,000 RPM and approximately 5,000 RPM.

Proposed is a portable self-power-generating apparatus which has small size and is capable of charging a battery by realizing self-power generation with high efficiency in emergencies in which normal electricity supply is not available, such as a military operation, a refugee village, a disaster caused by earthquake or the like, an emergency situation on ships, or an outdoor activity, and which can be used in combination with various smart modules.

The present invention is able to extract significant amounts of energy from a user who is walking or running while remaining discreetly hidden near an area of the body where many people already carry things (e.g. wallet, smartphone, keys). The user benefits by keeping their device(s) charged for a longer period of time without the need for external batteries. In addition, the present invention encourages an active lifestyle, which has been shown to promote good health and reduce the risk of many diseases.

An energy generating physical exercise machine that generates energy from exercise machine's guiderail's user generated movements that turns over one or more dual directional ratchet gear systems that turns over said axles which turn over one or more alternator generators which connect to and charge one or more battery banks in one or more child proof battery bank compartments for energetic storage and usage via transferal by one or more power converters from D/C to A/C energy and from variable voltage levels to regulated and predetermined voltages such as standard household and industrial Voltage levels of 110V A/C, 220V A/C for usage of said power from one or more external plug-in panel(s).

Methods and apparatus to power an exercise machine are disclosed herein. An example exercise machine includes a power receiver to measure a power output by a generator that is to convert movement of a moveable part into electric power, the power receiver is to calculate a rotations per minute of the moveable part. A mode controller is to calculate a power supply duty cycle based on the power output by the generator, the rotations per minute of the moveable part, and a user selected wattage. A power output controller is to control power provided to a console of the exercise machine based on the power supply duty cycle.
