Alternator to generate power?
If got an old car alternator and want to connect it to a battery, I'm using a waterfall to turn a bicycle weel with blades, to turn the alternator.
is the slow speed going to be a problem?

Yes you can do it , use and DC motor a diode bridge and a capacitor with a large Capacitante mora than 6800 uF to almacenate the energi, and you can add and "voltage doubler" or "voltage triplier" :)

Then the current will be minimized by the multiplication ratio and efficiency.

A
coil generated voltage using a magnet increases as the speed of the
magnetic flux passes over (through) the coil wires... The regulator
keeps higher voltages from developing at higher RPM.
YES, low speed is a problem for a car alternator. even with the regulator disabled for full output..
You might do better with a bike generator.

Yes, you;ll have to gear it up to the sort of speed the alternator wants, which is probably at least 3000RPM

"is the slow speed going to be a problem?"
Yes, almost definitely. The alternator is designed to run at the RPM your engine runs at. Turning it at like a measly 30ish RPM (guessing) isn't going to do anything. Might generate a few microvolts.
