3D Animations In Mid-Air Using Plasma Balls

An anonymous reader clues us to research at Japan's National Institute of Advanced Industrial Science and Technology that has produced the ability to make animations by creating small plasma balls in mid-air. The technology doesn't use vapor or strange gases, just lasers to heat up oxygen and nitrogen molecules above the device: up to 1,000 brilliant dots per second, which makes smooth motion possible. When the tech improves it could be used for street signs or advertising.

    Hah, who sees an amazing technology like this and immediately begins thinking about its potential use for advertising? To me, its use in advertising seems like the only downside to this technology..

    Forget it, that's not the early adopters.

    It'll be used for video games and pr0n. We all know who gets tech first. The problem I see is that it heats up they air to the point that when you get too excited and attempt to touch... You loose a hand or other appendage.

      Yup, so the real question is what is the military going to do with little projected plasma balls...

  4. Polluting? by Lazarian · · Score: 4, Insightful
    Wouldn't heating oxygen and nitrogen in air with lasers to the point of making glowing plasma also create ozone and nitric oxides? This sounds like it would be the same as having dozens of electric arcs going off in mid air.

    As much as I like the idea of being assailed with even more ads everywhere I look, this seems to be a very environmentally harmful idea. Along with harmful gases being produced by plasma discharges, it would be noisy as well, not to mention that displays like this would give off UV light as well, just like an electric arc. Bad idea.

      As long as they put the device in a sealed box, this would not be a problem. Maybe they could use neon/argon gas as they do with ordinary tubes, thus eliminating the danger of creating oxides.

  5. Unintended side effects by Caerdwyn · · Score: 3, Insightful
    Interesting stuff. However, I'd be concerned about unintended side effects... specifically, nitrous oxide and ozone.

    When you heat up an oxygen-nitrogen gas mix to those temperatures, you will get nitrous oxide and ozone. This is not just a problem with cool little sparky devices. Hydrogen-oxygen fuel systems (think: Saturn V) may produce only water vapor, but at such a high temperature from the exhaust, the oxygen-nitrogen atmosphere does its thing and... nothing you'd want to breathe.

    And ozone, while very nice for blocking UV rays, is a carcinogen when inhaled.

    That being said, I'd certainly love to see a demo. If they can somehow deal with the ozone/NO2 hazard, this could be a blast. "Help me, Obi-Wan, you're my only hope"

  10. Not just a vacuum cleaner by CustomDesigned · · Score: 3, Insightful

    The propane tank is used to generate CO2 (queue global warming rants here). Mosquitos are attracted to CO2 because that is how they locate their prey. When they fly close enough, then the vacuum cleaner comes into play. Zapping them is no good because they don't like ozone (so the plasma ball suggested elsewhere would not attract mosquitos - it would kill lots of moths, however). To be effective in protecting your event, the CO2 generator needs to be upwind. Mosquitos follow CO2 plumes upwind toward their victims using biotech similar to lobsters (compare the concentration detected between two antenna and turn toward the stronger, the greater the difference, the greater the adjustment - simple and effective). Those downwind of the BBQ will likely head toward that instead, so put the BBQ off to one side relative to the breeze.

      You lack imagination; the original poster was assuming that another part of the system would be able to, in a large volume of space (e.g., your living room), detect and correctly classify flying insects as a mosquito, rather than merely attracting it with some kind of bait. The plasma ball would be formed on-the-fly around the mosquito, killing it.

      Frankly, I'd be nervous about having that kind of automatically controlled laser capability in my living space. Maybe you thought about that too, and assumed the poster couldn't possible mean what I think he meant....

    I always wanted to make one of these! Passive sonar to locate the bug, and then a laser tracking system to set the little bugger on fire. :) Never got past the safety aspect though - I mean, we're talking about using a laser strong enough to punch a hole in a mozzie, being aimed around the room and fired by a system that could well just decide based on a strange echo to pop you in the eye. I'll take itchy over permanent blindness, tyvm. :/

    Other ideas were the same tracking system attached to a nerf gun, an automated micro-water-jet system (think an archer fish), or even something funky with focussed sound waves and constructive interference. ;)

    hmm... Another thing that might work could be to have multiple sources for the energy.. (i'm no laser expert :)

    But my idea, have a system with maybe 20-30 lasers that all focus their low-power beams on a single point. 10x20mW lasers should(?) have a total effect of 200mW, but ofcourse if you hit different parts of the bug it will probably not have any effect on the bug itself... Maybe put 10 lasers in a row instead of all around the room could make it a bit easier to hit the same spot, but then again, if the system thought your eye where a mosquito... :)
