A great step!
Next is build one.
Then cheap-ish and durable.
I doubt this will ever become any useful at all. 50 Watts is nothing compared to what the car engine outputs at high speed. Even a small engine has some 35kW, i.e. 35000 Watts.
I could see it maybe being used as an emergency back up alternator, just enough to keep lights on and engine firing (with storage) to get you to safety.
Do alternators fail that often?
Nope. It does suck when they do.
Wouldn't be powerful enough actually. You're better off having a battery that's in good condition. I've done nearly 100 km with the alternator belt off. It being a diesel, it didn't need to fire sparks though.
That's cheating :P
