    Just a heads up to anyone wanting to leave comments or questions for Dr. Ben…

    So, for a Thermo-siphon solar hot water system with a natural convection COP must be infinity?!

      Theoretically, yes. But there are several real-world limitations that would make such a system commercially undesirable. Primarily the fact that the solar thermal system energy output would be constrained by the availability of the natural convection. It has been shown that installing a real pump increases the energy collected by much more than the energy to run the pump.
