unfortunately, the article is lacking in details. I wonder what kind of batteries it uses? I wonder where it can recharge? I wonder what the top speed is?
 
It says it uses 1080 "12-volt" batteries. That suggests to me they are just good old fashioned lead-acid batteries car batteries, although maybe like 8D truck type or something. If they are 8D, near as I can tell the stats on those are roughly:

2.3 kWh
120 lbs
11W x 20.75L x 9.6H
~$200

So 2484 kWh, 129,600 lbs, $216k. All sounds doable. Plus you get the benefit of just using a cheap OTS part.

Besides, locomotives use DC traction motors, right? Weight and size wouldn't seem to be an issue, since you'd have a big savings on weight and space with no engine, fuel tanks, generator, or rectifier stuff to accommodate all those batteries.

I wonder how far you get with a locomotive pulling a train with 2484 kWh. I bet they don't use much once you get them rolling.
 
This seems bizarrely relevant:

Confirmed; 1,080 12-volt lead-acid batteries. I guess weight isn't as critical as cost!

Here's an idea: Build battery packs into ISO containers and hook up whatever you need on cars modified with appropriate wiring. Swap the battery just like you'd load and unload the containers!

More or less all of the modern ones use AC induction motors like Tesla does. There might be a few odd ones using PM DC brushless, like the Leaf motor.

And 1500hp is a really small one, suitable only for switching use. For comparisation, the electric locomotives used for hauling passenger trains in Norway have nearly 8000hp. Of course, these run from 16kW overhead wires, not batteries ;)

16kW will propel my 1500kg (3350 pounds) LEAF at about 100 kilometers per hour (62mph). I'm very anxious to the get the 8000hp version on 16kW. :mrgreen:

I think you all should meet Diesel:

I remember watching these as a kid. We had George Carlin or Ringo Star doing strictly narration, no other voices. :D

Does that have electric motors driving the screws, or does the steam power from the reactor run turbines that drive the screws through reduction gears? Not that it matters, it's bad ass either way.
 
CVN-65

Propulsion:
- 8 × Westinghouse A2W nuclear reactors
- 4 x Westinghouse geared steam turbines
- 4 × shafts
- 280,000 shp (210 MW)

Range:
- 25 years :shock:


I like their unit of measure for range.

Technically it's steam propulsion in the same way a nuclear power plant uses steam to spin generators. Except while these steam turbines not only generate power for all the ship systems the turbine/generator shafts are also attached to props.
