Seeking help with using caps

[lexcity]

I'd really appreciate it if anyone could answer my question or refer me to sources that would explain how to do this:

My setup would be a small alternator, that is charging a bank of caps, the caps would have a timed discharge to turn an electric motor (this is not the entire setup but the part I need help with). Can anyone tell me where to find information about how to connect the caps properly, any kind of timing circuits that can be hooked in and how; or whether I should just use batteries instead? Thank you so much for your help; if I can get this built and it works I plan on sharing it here.

The project you've described would not be too
difficult to implement.  Ideally you'd want the
alternator output voltage to be much greater
than what the DC motor would require.

The capacitor bank would be charged to some
relatively high voltage by rectifying the alternator
AC output into DC pulses.

Then the capacitor bank stored energy would be
applied to a DC to DC Converter to down-convert
the high voltage to the lower voltage required by
the motor.

When the capacitor stored energy is exhausted,
re-charge the capacitor bank and repeat the
motor run time.

It would be very helpful to know what your
intended voltages are; for both the capacitors
and for the motor.  What sort of power level
the motor needs to operate at and the desired
amount of run time.

DC to DC converters for down-conversion
(Buck Regulators) are now available which
can function well over a wide range of input
voltage to efficiently accommodate a declining
capacitor bank voltage input while maintaining a
steady output.  Provided of course that the
capacitor bank is sufficiently large.
