Sound into lightwaves, or sound into microwaves by acoustomagnetic resonance effect as it seems to be with a TPU or SEG. Because of the low sound speed compared to light speed, the wavelenght becomes short even with a low acoustic frequensies.

Odd but interesting hook up a solar panel and a cheap radio transmitter blast it with some sound light waves and see what happens ...

Light contains photons does it radiate?

Sound into light. What a useful idea!

Politicians could completely illuminate their own parliament buildings with all the endless rhetoric and meaningless sounds they make.

Now any government can be green.
