Ann: Preliminary Final Report, page-56

I get you Kappa1111. So I'll offer you my perspective. The processes of MEMS technology are infant. So patience is key. The market is wary, and so be it. The-market-is-always-right though is very old school. Where you are right is that the person who debunked "the market is always right" - John Maynard Kaynes, would unlikely have invested in AP until there was a product. Me on the other hand engaged in a PHD on alternatives to the moving-coil-loudspeaker and have made a model with spark machines (for artistic rather that tech purposes) of the audio pixel concept, prior to any knowledge of AP. The "pistons'" in AP's approach would audibly be similar to spark cracks. It isn't a fantasy. I would be sceptical if I hadn't heard how loud simple spark gaps can be, as any layman in 1944 would be sceptical an atom contained so much power And I've annoyed Yuval on numerous occasions to be confident this is no joke. If in doubt watch his old presentation: http://www.audiopixels.com.au/news/videos/digital-loudspeakers-video/
