Abstract

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.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A human-powered generator comprising:
 a rotatable pedal crankset;   a rotatable flywheel that is configured to be turned by rotation of the pedal crankset; and   an alternator that comprises an alternator drive shaft that is configured to be rotated by rotation of the rotatable flywheel such that a pedaling cadence of the pedal crankset of between approximately 60 rotations per minute (RPM) and approximately 100 RPM achieves an alternator drive shaft RPM of between approximately 2,000 RPM and approximately 5,000 RPM.
