Still, launching the package is doable in tens of years with plausible tech. Maybe. Enough to get 100 million to study it, anyway. #MAC2

If you're willing to put the laser in space, could launch sail after sail continuously: SailBeam. Sails fly into probe, accelerate it.

Dielectric materials retransmit, absorb less, more survivable.

Microsails: 32 million gs.(!) 0 to c (ignoring relativity) in .97 seconds.

Velocity limit of SailBeam: 86‰ of sail speed. If sails go 12‰ c, vehicle driven by it can hit about 10‰.

Artificial diamond good material. Zirconium oxide also good. Glass not too bad.

Must be v. transmissive, high tensile strength. Guidance tricky as range increases: sail flies light weeks, hits right part of probe?

Sail should spin for stability, or else it tilts and goes out of beam.

I am now imagining a "funny sailship" craze, with spinning umbrellas at all angles. Like Space Patrol: https://youtu.be/nmsTwQb1csc?t=52 …

Is it just me or is the video way out of synch with the beat?

hm, maybe because of starting in the middle. restarted at the beginning and it fixed it.

Yeah, that's an artifact of YouTube's occasionally flaky syncing code.
