I'm not fretting at all. It's going onto the my launch with the boiler. It's 22 lbs altogether alternator and stuart. The visual interest is excellent, it's a good demonstrator for those who think steam power is complete magic (which it still is ), and it could certainly do some practical charging to a battery. Sure Solar and LEDs would make more sense - but they certainly didn't have those as an options back in the day.Lopez Mike wrote:I wouldn't fret a bit about the efficiency of your alternator.
This is a case of why I like Bill Durham's attitude in his steam boat bible - there is enough water for all types of configuration of launches.
And in that vein I thought I'd just share my solution to a little bit of steam electricity as I was putting it together.
