[QUOTE="Per Søvik, post: 83735, member: 1285"] Re: New speaker tech.. *Graphene* Along the same lines as molecule size based filtering, I wonder if a stiff material, maybe graphene, could be made to produce sound without moving air? If the material is completely permeable for most of the molecules in air, and still dense enough to bounce a vast majority of the molecules, could one create the waves without having to use up a lot of energy moving air back and forth?
