Enter Nimbus. Nimbus is a serial novel written by a fellow blogger and friend, Professor Beej. The world of Nimbus is run on steam, but that's where most of the similarities with traditional steampunk end. The world is covered in a fog that kills or disfigures all who come in contact with it. The only remaining bastions of humanity are places so high in the air that the fog doesn't reach them. Since ground travel would kill everyone the only viable option for transportation is via airships that run on steam.
But water isn't just the power source for technology, it's also the base form of currency. Most people don't have access to clean water. Pure water is so rare that entire airships are dedicated to collecting water from clouds. Since water is so valuable it adds an interesting twist to generating steam and powering technology. People have to balance the benefit of technology against the cost of water it takes to generate the steam.
Take some time and investigate the world of Nimbus if this sounds even remotely interesting to you. Beej is releasing weekly chapters for free over on his site but I would suggest supporting this kind of writing by actually buying Nimbus: Part One on Amazon.
I can't recommend him as an author enough and it would be remiss of me not to mention his other project, Birthright. It's a completely different world but it seems just as interesting. His Kickstarter for the novel is going on now and has some free sample chapters included. If you're a fan of quality world-building you should donate!
