The intention was to pre-build and test everything in virtual space before a single part was purchased. SAFIRE is made up of a complex array of unique systems that need to be harmonized and synced together. A single mistake in the design of any one system could cost a small fortune, enough to put the whole project in jeopardy.
It is a measure of the team's success that when all the real pieces arrive on site the assembly proceeds in truly remarkable time, weeks instead of months. And when assembled the whole system is fired up and running as predicted within a few hours.
first firing up of SAFIRE
Everything learned in Phase One of SAFIRE (Proof of Concept ) is now applied to the Phase Two design, construction, commissioning, and first firing up of the full SAFIRE experiment.
designing the lab
Long before the purchasing of materials, before the assembly and construction of the Phase Two laboratory, Montgomery Childs and Jason Lickver design the entire setup in virtual space, with software.
The composition and capacity of each element and material is studied and factored in. Every single screw and washer is named. There are 40,000 parts to be accounted for.
Virtual 3-D models are constructed using high-end solid modellers.
Mechanical & electrical engineering, physics, chemistry, mathematics, computational fluid dynamics, photography ... all play an essential part.
OIPTS - Open Issues and Project Tracking
Montgomery Childs has developed a technique for managing complex projects like this. Called OIPTS - Open Issues and Project Tracking, the system is so efficient it has been adopted by numerous large corporate entities such as Toyota, GM.

potential failure modes
Software solid modelers (see below for examples) are run to determine where there will be problems. Lists of potential failure modes are drawn up. Using the solid modelers, problems are solved in virtual space long before a single piece of hardware is purchased.

In the process of getting SAFIRE up and running as planned, numerous experiments were generated. The results of these experiments suggest that the Electric Sun Model has viability. More interestingly, some of the results were not predicted. Startling discoveries were made. See for experiments and discoveries.
