I have a pretty good idea, I think, for an alternate history story, but I can't say I know vast amounts about history, nor am I an expert in the fictionalizing the onslaught of the butterfly effect. So in the story, the Industrial Revolution, which was spearheaded by the steam engine, begins in 1790, leading to a completely changed cycle of history leading up to a pretty weird world in 1943. However, I want to know if this is plausible at all, that the advancements of the Industrial Revolution would come early if someone had come up with the ideas for the basic mechanics used in that time earlier on.
