SS re alternator generating paddle wheel: MB's right. Alternators have to spin a good rate to output good current, and they are designed to spin at very high rates.
If my back of envelope math is correct: ....If 26" wheel AND TYRE ( its the tyre that makes the diameter 26") driving a 1.5 diameter alternator pulley from the outer diameter of the tyre, then the wheel would have to rotate at 120 RPM to spin the alternator at the equivalent rate to its speed when driven by a car engine running at 1000rpm.
120 rpm under load seems to be a big ask from the system you describe.
