If you really have reliable every-time line of sight, I'd imagine a
green laser from one building to a solar cell at the next building
would do the trick. The laser would need to be high off the ground to
avoid blinding anyone.

At 17 I did the analog equivalent. I placed the speaker output of an
amp in series with a flashlight with batteries, shined it into a solar
cell several feet away, amplified the output of the solar cell, and got
the audio loud and clear, if a little treble-challenged.

By the way, if you strike a match in front of an amplified solar cell,
the sound coming out of the amplifier sounds just like the sound a
stricken match makes without an amplifier. In other words, the light
patterns resemble the sound patterns.
