Nah...considered that but thought it too inefficient
Too many things going on to bother listing them.

We are running external combustion engines since when do we care about efficiency?

Lunch/beverage cooler on the side facing away from the boiler? Drop in a days worth of ice in the morning and voila… refreshing beverages plus a light to guide your way.

Ice in tender?

Are we talking about steam locomotives here???
How about a tried and proven steam turbo-generator? In scale size, no less, even for 3/4" scale aficionados. Imagine that, just like the prototypes.
A well designed and executed 1 1/2" scale size turbo-generator would even keep your cell phone charged.
Just imagine, with the boiler at pressure, simply open the steam valve and walla, instantaneous light.
These beasties were amply described and debated in another thread on this forum.

I suggest you do so! Especially if you'd enjoy a few laughs. It's not only educational, but he's a pretty funny guy. Well worth watching.PRR5406 wrote: ↑Sun Jan 29, 2023 11:03 am check out Mehdi Sagdahar's Youtube channel A.K.A. "Electroboom"

Re: Peltier Chips as an electrical source?
Glad to see I'm not the only one that has thought about this
Some years ago I drew up plans (but never built one) for what I call a "Seebeck Generator", after the German scientist that discovered the effect (independent of Peltier).
My idea is to create a steam channel for the hot side, similar to the one shown here https://customthermoelectric.com/media/ ... -AL-R2.pdf, and connect a low-volume steam flow to the channel. The "power output" could be controlled by a steam valve to the channel. The "cold" side would be attached directly to the metal of the tender water tank, perhaps under the tender.
One of the problems to overcome is the heating of the tender water, which would cause issues with injector operation. Keeping the tender full of cool water would certainly help.
I'd love to see someone implement this.

ICE - fill the tender ice and make slush.
did this in the mid-eastern desert 45+ years ago -> just to get injectors to ever work....
