The alternator in my truck is going on 25 years old. I don't think that would be too much of a concern, and if it is buy a spare. Between the two they should outlast you. Besides you can make an alternator, just buy some magnets and look the plans up online. Also the water wheel can be used for much more than powering an alternator. You can run almost anything off it. You can run a compressor, mill, heck anything that spins.
