Do you think this will work? long term? The only thing I am having trouble understanding is electronics.

This comment from Youtube stuck out to me ...
I'd love to hear what an EE major (they are here on the forum) thinks of this one. Personally I agree with the commentator.
If you, like most people, have 0 electrical background (who is Ohm and why did he pass laws??) then it is probably a good idea not to mess with this type of stuff.

I'm an EE and find this interesting but not a solid long-term solution per the quote Brian refers above. If you are a hobbyist and like to experiment then this might be worth trying out but otherwise I don't see it as really that useful. I'd also have some safety concerns just because there's been no real engineering or long-term studies done seeing this thing in a wide variety of conditions.

Nope. Don't leave your lights on for too long. Capacitors are not designed to hold charges for a long periods of times. The capacitor charges and discharges extremely fast; batteries don't. You also risk damaging your electrical circuits through-out your vehicle. That is not worth gambling the integrity of your electrical system. Especially since it's a whole lot of ass pain to troubleshoot electrical gremlins. It's a big risk for such a small reward.
We have a saying in the electrical world: "If it ain't broke, don't fix it."

Yes. If the capacitor was discharged the initial surge current as it charged could blow the fused link from the alternator. You would definitely need a current-limiting resistor [a HUGE one] between the alternator and capacitor. Overall, not a practical solution. If it were car makers would jump on it since it would be much cheaper and "greener" than batteries.

Capacitor -short term electrical storage device.
Battery - long term
Capacitor has the ability to supply huge amount of amps in a short amount of time. Nanoseconds.
This is why it seams to start better.
Plus, If the alternator was to loose its regulating capabilities and over charge the capacitors, they could blow up like a stick of dynamite.
