SKY MINING
Above) Skyhook with turbo-harvester is powered by energy from the artificial miniature black hole beamed via microwaves to the axial compressor.  It all depends on exotic super materials like buckminister fullerene cables, tubes, etc.
The DRIVERS are located in orbits inclined to the plane of the ecliptic.  Alpha Centauri is well out of the ecliptic in the southern sky.  If the beams from Venus hit Earth there will just be an aurora.  The Drivers are not planet killers!  The beams from Titan and Uranus are not eclipsed by the planets they orbit and can supply constant thrust to mag-sailing starships of the future.
