Well, there is no reason for me to make something like this up, Im telling
you, it does work,
For the 7 buks it would cost for a small solar panel and a lazer pointer ,
try it out. PLEASE.

It couldnt have worked because, IIRC, solar cells do not respond fast
enough to convert the signal back from varying amplitude light. Plus
connecting up the laser would not be as simple as you suggest. you
would need to use some sort of phototransistor to get a reasonable
response speed and sample sound from it.
