Offers better brine handling and produces higher-purity water, making it ideal for offshore green hydrogen production. Sustainable and efficient solution with low environmental impact.
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.
