: Well, first of all you need a "Larry Lesson" on how batteries charge as your 110 amp alternator is just a waste of money. No, no! Everyone knows a boat battery can be charged in 3 minutes if you buy a big enough alternator! Don't let logic, battery chemistry and me upset it. |

Everyone knows a boat battery can be charged in 3 minutes if you buy a big enough alternator! Don't let logic, battery chemistry and me upset it. I had a 1988 mustang ragtop that had about ten interior lights and a small battery. If you left a door slightly ajar, the battery would be completely, 0 volts, dead in 45 minutes or so. A ten amp charger would put in enough juice to start it in ten seconds. Then comes the charge from zero at the maximum rate. Needless to say, that battery didn't last long. Casady |

I have some big aluminum heat sinks I got from somewhere. I think I'll play a little with them stuffed into the little freezer and see how that works as a holding plate....hmmm...(c; Badly. You would be much better off filling the freezer with a phase change fluid that melts/freezes somewhere in the desired temperature range. Water, for instance... The exterior of a typical little bar fridge is a heat dissipation surface, so insulating it from the surroundings would be a bad idea. Ryk |

No, no! *Everyone knows a boat battery can be charged in 3 minutes if you buy a big enough alternator! Don't let logic, battery chemistry and me upset it. In practice high output alternators make a big difference getting up to about 80% charge. That can be very, very useful. It may be that you have some logic and battery chemistry in your text books but I live on my boat and go voyaging a bit. High output alternators are a good thing. Bummer about the Smart Car. AFIK, they aren't importing the diesel version because in CA you can't buy diesel cars w/less than 7k miles on them. As they say the road to hell is paved with good intentions... But, what you really want is a diesel plug in hybrid... -- Tom. |

None of this namby-pamby refrigerated stuff for he man, AND, since you don't drink beer you have even less need for a fridge then usual. The RN rum issue was originally a substitute for beer. Small beer, so called, one per cent alcohol or so. It was sure as hell not refrigerated.[or even iced] Casady |

I'd be interested to see what results you get. cheers Peter |

I just looked at one in a 45 ft. boat and it looks like the compressor is running much longer then a "built in" with thick insulation. However, I am in the process of rebuilding an old motor cruiser and plan to install a small house fridge as the boat will generally either have the engines running or be tapped into a marina.

(Well, larry doesn't live on one, he just voyages). Frankly, in my experience a 110 amp alternator and a 440 A.H. battery bank is overkill, Bummer about the Smart Car.
