My bad. 4th installment, 3rd chapter.

Chapter 2 is now up. The direct link is here for those that need it: http://www.jim-butcher.com/books/cinder-spires/the-aeronauts-windlass-1/aeronauts-windlass-chapter-two. What had been previously released was indeed only about half the chapter. I preordered this book some time ago. If I hadn't, reading this chapter would have had me running to Amazon with my money in my hand. . . and we haven't even met the cats yet. This promises to be another fun ride.

BTW for anyone looking, the new chapter is here: http://www.jim-butcher.com/books/cinder-spires/the-aeronauts-windlass-1/aeronauts-windlass-chapter-one

FWIW this is the direct link to the first installment: http://www.jim-butcher.com/books/cinder-spires/the-aeronauts-windlass-1/aeronauts-windlass-prologue

The directions above, however, will allow you to find each new installment as it is posted.

I mean, if we used Electricity as a currency, it wouldnt matter who generated the voltage and charged your wallet/battery, the Charge exists. 

In a society where the money has actual value (gold, silver, etc.) it is very possible that raw metal would be acceptable. The problem is that unless you are an expert, it might be easy for someone to fool you (gold covered lead for instance). Coinage that has been certified by some authority, usually the government, is considered safe because you know exactly what you're getting. I could see the same thing in a society that trades in elemental energy. Any elemental energy would have value but most people would feel more secure using "coinage" that has been certified by the Guild. Anyone that tried to fake the Guild's certification would call down the wrath of the elementals.

Many books and/or series have a group of powerful supernaturals whose job it is to keep the supernatural a secret. This may include such things as repairing damage, wiping and/or changing memories and creating cover up stories in the media. They may also be responsible for punishing or destroying anything that tries to make the supernatural knowledge public. Sometimes it is a governmental agency that adds its legal power to the supernatural power in keeping secrets. The Pax Arcana series has a massive spell in place (called the Pax Arcana) that keeps the secret. I don't remember all the different things the spell does but it keeps the majority of the population in the dark about what's going on.

How big is the supernatural in your world? Are there vampire nightclubs, werewolf biker gangs and huge bazaars run by demons or are there just a few scattered supernaturals that are easy to disbelieve? It takes a lot more, especially in the age of cell phone cameras, to cover up a major magical battle that leaves buildings a smoking ruin and pedestrians half-eaten than it does to cover up the disappearance of a homeless person that has been preyed upon by something hungry. Is your supernatural world going to be loud and bright or subtle and hidden in the shadows?

I like Neurovore's answer as well. If the magic has been gone for a while but is slowly coming back or was stopped by some cataclysmic event (the sinking of Atlantis for instance) and is brought back by something equally large then people still be unaware that it exists.

I always thought the  term was referring to the fact that a normal outhouse was usually wooden and fairly poorly constructed. One that was made of brick was far superior and far better built than the norm so a woman that was built like a brick ****house was far "better built" or had a far superior body to the norm.

There must be aeronauts and Jim said there will definitely be goggles so I wouldn't be at all surprised if there were dirigibles, zeppelins and blimps.
