Interesting Applications for Spells to Benefit Society

[Phylotus]

This has been rattling around in my brain for a while now, specifically because I'm trying to imagine a Golarion in a setting with technology on a similar level to the 1940's. The one thing that stood out to me was the discovery of steam power, and then the magic used to replicate it without expending resources:

Permanent Heat Metal + Decanter of Endless Water

What other forms of technology may be different? Discuss!

Yes, I know steam isn't a mainstay of the 40', but the Industrial Revolution; I thought of steam power because of how pivotal it was in the progress of technology, and I can't help but wonder what else would have been different as time went on
