To be clear, none of this stuff is going to work on the first try. The Project is a research-and-prototyping facility. It's the place which tries out ways of doing this stuff in practice, and gets it working well enough for a major refinery or forge to be built -
- presumably somewhere else, next to an iron-ore mine, or a coal mine for coal fuel, or a forest for wood fuel if adding fire elementals can make wood fires suitable for refining or forging. Unless Teleport logistics are very different from what Keltham suspects they are; people talk about the Worldwound in a way that suggests Teleporting lots of stuff is a significant expense.
