    This is extremely strange. Shouldn't this be impossible by the second law of thermodynamics?

    Receiving more energy when a resistor in thermal equilibrium is connected to an antenna seemingly implies that energy gets transferred from an antenna with a resistor to a an antenna without a resistor, even at thermal equilibrium.

    Maybe we'll later find it's an experimental subtlety, like the faster than light neutrinos.

      AI will explain it, but it's against HN rules for me to post the explanation.

      Basically they are misleading when they say "thermal equilibrium", same physical temperature does not imply thermal equilibrium.
