The Original Models

Dagnabbit Jorge. I tells ya, there aint no Original Models. Tha's all jus' a conspir'cy theory from half drunk ast'roid miners like us.
Martyn, I tells ya, it's all true. Them Sisters set up their parents, and half th' elite o' the world at the time. They hid th' origin'l models 'cause them was proof o' how the demonstration was sabotaged. I tells ya, them models'r still 'round, hidden someplace on Luna. Someday th' Underclass'll find 'em, an we'll all know just how evil them thrice-damned Sisters was.
Shut that, Jorge. You know th' walls has ears. You keep talkin like that an' the boss'll show up her t' tell ya' yer position been closed an' yer Unemployed. Might do me in too, so fer the love o' all tha's good, shut the frank up.
OK, Martyn. I'll stop talkin 'bout the models 'round here. Can't stop me thinkin 'bout it, tho'.
With that, the two miners finished suiting up, and made their way outside to begin their next shift working the solar concentrators that used brief high intensity bursts of heat to blast the asteroid rock apart, exposing the valuable metal veins.

The Original Models. Few items were more sought after, and more subject to controversy and myth, than the original development and working models of the first practical fusion power systems. That they once existed is unquestioned. The few documents that survive from the development process clearly describe at least 15 developmental devices ranging from structural models to the first experimental working devices, up to the last few development units as the work slowly crept up on breakeven and then commercial scale. Many inquiries have been made over the past century to find those models, or any other documents regarding the development process. Every inquiry attempted independently has failed to find anything. Inquiries to The Sisters always receive the same pro-forma response.

As you must understand, the family was devastated in the days following the Demonstration and tragedy. Many personal effects had to be sold, some merely for scrap, to pay debts, and other items had to be dismantled to understand their function, so that the life's work of the deceased would not be lost.
The Sisters regret the impact to history and historical research, but tragedies have costs, and the cost in this case is that while Humanity has benefited immensely from the technology created, the origin and development of that technology is largely lost to history.
We encourage you to contact The Museum of Fusion Power for scholarly access to their collection of documents and artifacts, which includes every known resource that has been preserved from that time.
