That's exciting even if we are still far from a real product. There is a place for a new way of manipulating light and giving that to artists. For me, it can le be linked to the demo that Intel is going with drones and light, but on another scale...

But there is nothing new here. Artists are free today to levitate things above ultrasonic speakers. Google ultrasonic levitation. Just dont expect any local cats to be happy about your next street art installation.

I don't get it. Maybe I'm missing something, but how is this in any way novel? You can get a cheapish acoustic levitation kit from Tindie[1], and inductive power transmission is hardly a rare technology these days, so where's the innovation? It seems to me all they've done is made a tiny LED with a tiny coil attached to it, right? And how the hell do they expect to achieve any of the ridiculously speculative things t…

It is cool but the goals they have are total bs and they know that themselves because noone who unserstands how this works would believe that stuff

Although I haven't looked into the exact mechanism here, I think people who find this interesting may also be interested in optical tweezers. https://en.wikipedia.org/wiki/Optical_tweezers

The mechanism here is more like https://en.wikipedia.org/wiki/Acoustic_tweezers.

There is a place for something smaller and more flexible, it's not clear from the article it this method can scale, however.

Earlier quoted context omitted.

Finding out that it was actually a prequel bummed me out so much.

was A Fire Upon the Deep not good?

Fire Upon the Deep was good, but was sad to find out what happened to Pham Nuwen. Makes the ending to the prequel rather bittersweet.

Loved both books though :) Sorry if I gave the wrong impression.
