No. There are generators that are coupled to an electric motor.

So the electric motor uses power from the dead batteries to run the generator to recharge the dead batteries?

Sorry, I don't believe in perpetual motion.

Sailor Steve, not on subs, but on a US Navy Surface Ship thank can generate a tremendous ammount of electricity with its Electrical plant setup.

Still confused by what you mean. So, an electrical motor can, in priniciple, turn a generator to produce electrical energy. But the motor has to get it's electrical energy from somewhere else in the first place, so what's producing that?

Every ship I've ever been on generated it's electrical power either by alternators run by power takeoffs of some kind from the main engines, or from a standalone diesel or gas-turbine generator combination (and I've toured warships that would have used steam to spin their genetators, just never sailed on a steam powered ship).

While it may be very well possible to charge a subs batteries from a ships energy plant surely it would be easier to transfer some fuel. In either case were still back to a 'rescue at sea' which is not modeled in the game.

I also mentioned the "batteries & diesel" thread. i agree thats a realism issue more than to call a tug to come and get you.

The reason for this question is that my diesel engine is not running and am afraid the hull is not gonna hold if i dive, and i amn about 9-10 hours away from a sub tender at slow speed.

All I can suggest is to submerge as little as possible (in increments, clicking on the shallow depth guage) until you can get the motors turning. If you've not gone into a death dive by then, head over to the tender at 2 knots.

Yes, i know. Butt i miss the possibilities to do it on the surface....

Which is powered by? A battery? I think you'll find it can't generate any electricity at all unless the electrical generator is being powered by the steam turbines.

I agree with Seafarer on the weight. The manual says:

The weight of one cell ready for service is approximately 1650 pounds without intercell connectors or vent ducts.

Sailor Steve, the Nimitz Class Carriers Have Motor Generator Sets aside from the SSTG's, that generate electricity. Very redundant setup they have.

You mean like these - http://www.horlick.com/products.asp?cat=64 ?

Note that the motor driving these generators requires it's own, outside power source. Nothing's free in this world, especially energy

Thanks for the explanation, seafarer. I was beginning to think they were supposed to work by magic.

Cool but uh again what is this cells Voltage and Ah rating ?

Phew I can imagine the mess it would make if that thing got shorted out.
