Floating Video Displays

If it works how I think it does. Its just a cloud of water which is just about invisible but enough to refelect light from the projector. Which is why the image isn't very stable because the cloud can't be relied upon to be in the right place. I seam to rember reading about it somewhere
 
if it was water, how could the guy put his hand through it?

more like a cloud of particles, blown on air or something, which would also account for the instability

surely the more important bit would be that if he put his hand in it, and its blwon from the bottom why isnt the bit on above his hand distorted/cut out

anyhow thats well coool :)

personally id prefer the bendy screens, like in that film to mars or whatever.

I've read about it somewhere too, a few years back

I think it was being developed by LG for shopping mall displays so people could walk through them.

Definately some kind of light reflective gas.
 
Ever put your hand through steam....its a cloud of water (albeit warm water). The advantage of water is that you don't need to contain it and its pretty cheap. It might be something else but I don't see what difference putting his hand through would make. Its hardly poisonous :confused:

The steam has to flow around the hand and will not instantly form on the other side of the finger, the finger dissipates the steam, thus his point was why is the image above his hand not completely screwed when he puts his hand in it.

Although saying that, it appears flawed in that the image, from the smart car bit is projected at an angle...
 
Until we can all go down to our local car salesman and buy a hover car for around the same price as a normal one then the future is not here, im also thinking along the lines of propellerless and jetless propulsion.
 
Allright. Now, a lot of people were confused by your explanation of just how the machine gets the lasers to display the image. What exactly is a laminar layer, for instance? How does it work? Can you elaborate?

Basically, we are creating a thermal differential within the air and as soon as you do that, the air goes through a process of rapid condensation. So what we’re doing is transforming the air in a very localised fashion.

So this is making use of the same phenomenon you see when airplanes leave contrails high up in the sky, then?

Exactly. That’s really as much as I can elaborate on this point. I will say though that it doesn’t put anything in the room that wasn’t already there and it doesn’t remove anything. It does what it does very locally.
