"New study links widespread ultrasonic 'firefly' devices with disappearing insect populations and [other unintended ecological disaster]." - Headline from 2042
A Fire Upon the Deep is good. It might not be what you want out of a follow up story set in this universe. It has a heavy focus on a low technology world deep in the slow zone.
I'm confused. The article implies that it can hover around independently, but in the gallery, it's only seen levitating inside a fat loop of copper wire connected to a stationary structure.
"Japanese scientists invent floating 'firefly' light" followed by "Japanese engineering researchers say..." I'd guess it doesn't involve any new science and is purely an engineering project.
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 they talk about in the article anyway? Fleets of these things flying around drawing messages in the sky isn't particularly useful if you need to position a massive bank of ultrasonic speakers and a power coil underneath them.
It all smacks of the Hendo Hoverboard[2] bullshit which bad "science" "journalists" breathlessly obsessed over a few years ago, which was similarly just a rebadging of existing technology that was utterly impractical in any context except marketing, coupled with thoroughly nonsensical claims of future utility (levitating buildings during earthquakes, for instance.)
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.

Would that much ultrasonic power be enough to burn human skin?
The ultrasonic puffs of air keep it suspended.
Loved both books though :) Sorry if I gave the wrong impression.

"and be built to float about, helping us in our everyday lives"
This guy has grown up on Ocarina of Time and thought "I'm going to make that happen".
