pfc design notes 005 - Better Interstellar 3D Lithography
After my last post, I realized there's a better way for the Algeans to do interstellar 3D lithography.
This system uses two stars as gravitational lenses - the source system's star, and the destination system's star. This uses a relatively small X-ray free electron laser. It aims a fan shaped beam near the edge of the source star. The source star acts as a gravitational lens focusing the beam into a perpendicular fan - aimed near the edge of the destination star. The destination star then acts as a gravitational lens focusing the beam onto a small point at the destination Oort cloud body.
This etches robots out of methane ice, which then produce more sophisticated robots using local resources. They use a sort of geothermal fusion power. Deuterium is harvested from methane/water ice, and used to create fusion bombs. The fusion bombs are detonated underground to create steam; the steam powers generators. My point is...they don't use solar power. The Algeans evolved in a biosphere powered by extreme tide-powered volcanism. Their home system's brown dwarf did not provide much sunlight, so they never really developed solar power.
The biological Algeans may have died out, but their legacy lives on via their VN automata. The VN robots colonize other systems by taking advantage of the occasional alignments between the source and destination stars...
That's all for part 005!
