I exploited that in the setup for a Steampunk campaign...

I remember reading that it couldn't happen anymore but, as you stated, it is possible in a game setting.

I also remember when it dawned on me that we still have one foot in the Age of Steam.

I'm not a scientist or an engineer, but it seems we're pretty much stuck with muscle power, radiant heat, moving fluids, steam pressure, electricity, and combustion. (Did I miss anything?)

Many people seem to see it all as magical crystalline engines that push cars and tv shows.

In the context of a Solarpunk rpg setting, barring the supernatural and handwavium, what else might there be?
