    &gt; Although the current cloak represents a major advance, the researchers want to develop more sophisticated versions capable of performing additional functions. One particularly important goal is to conceal objects that produce heat themselves<p>I read the entire thing thinking it could cloak a soldier

      It could cloak a well insulated soldier from being a dark spot on the background.

    This is gonna be going straight to Ukraine

    This headline is wrong. This has nothing to do with thermal cameras. It&#x27;s &quot;cloaking&quot; by making it appear to have the same bulk thermal properties as it&#x27;s surroundings.

      Yes. Unfortunately many people are reading this thinking it&#x27;s a FLIR invisibility cloak.<p>FYI Ukraine already has FLIR invisibility cloaks (fancy camo space blankets): <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=GfdF3iIwoX4" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=GfdF3iIwoX4</a><p>This is <i>thermal</i> cloak, explained here: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=CM2RJi4mRZ0&amp;t=52s" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=CM2RJi4mRZ0&amp;t=52s</a><p>Notably it only works after the heat flow settles back down to equilibrium. If you&#x27;re moving, it doesn&#x27;t work.

        Which seems like it would be good for fixed installations that need to remain undetected, no?

          The other caveat is that it only works if you&#x27;re embedded inside a solid object. ;)<p>If you&#x27;re in free space, the surface can&#x27;t shine its IR differently in different directions, so under FLIR it will just look like the average ambient temperature. This is no better than existing (cheap and light) space blanket camo systems.

    Does this work for things that <i>emit</i> heat?
    • SeanAnderson4 hours ago
      Doesn&#x27;t everything emit heat? :)
      • chorsestudios14 minutes ago
        no, the vacuum of space does not emit heat
    • glitchc4 hours ago
      Let me answer your question with a question: Does the infrared camera detect emitted heat?

    A Faraday for heat, eh?

    Wow, a blanket!
    • scotty7914 minutes ago
      When you cover yourself with the blanket, others see the blanket. When you cover yourself with this, others see background.

      Is dismissing people’s work so rudely how you make yourself feel superior?

        that guy taught me something new about glass in a snarky fashion , while you delivered pure snark. no comment to add, merely an observation
    • tarpitt5 hours ago
      you can&#x27;t make a drone entirely out of glass

        Can you fly a drone that&#x27;s covered with a cloak?
        • mrandish4 hours ago
          Probably not very well if the drone is the typical (quad)copter type since the shield will likely obstruct the airflow from the propellers reducing lift. The added weight of the shield is also likely to be a problem in small drones as most are already weight constrained. Although in small electric copters like those used in Ukraine, I&#x27;m not sure how often thermal imaging is used as a primary detection vector (due to size, distance and daytime thermal delta from below).<p>Thermal is definitely a primary vector in detecting larger drones like the Reaper due to large combustion or jet engines, but in that case the challenge isn&#x27;t cloaking the drone, it&#x27;s cloaking the heat of the vented exhaust that&#x27;s likely leaving a thermal &#x27;contrail&#x27; across the sky.
