    When using solar directly to heat water how much more efficient can you get than a black container?

      Coaxial vacuum tubes allow solar light energy in through the vacuum but the heat energy can’t escape that way. The center conductor is black and a heat pipe to heat the water.

      Super duper efficient

      Ed: also regarding a black container not vacuum isolated, the heat energy will be lost to the environs just as fast and efficiently as it is absorbed. Ref: Black Body Radiation

        Just to clarify your comment for other readers: the coaxial vacuum tube do a better job of putting the heat into the water as opposed to the surroundings.
