Ah, yes, but I just had another brain far... I mean storm! The exterior copper pipe lining/jacket which encases the external reactor "torus" wall might assist in the transfer of reactor heat to the adjacent flowing water. If the reactor "torus" had been built entirely outside of the copper tubing holding the flowing water only the internal "torus" wall of the reactor would be able to transfer heat to the adjacent water. The external wall of the "torus" configuration would not be able to transfer ANY of its heat to the flowing water. Just a thought. Someone who knows how to run Finite Element Heat Transfer software should run several simulations to see how generated heat might transfer using various reactor torus configurations... such as with copper pipe entirely encasing the reactor ring... and also with the copper pipe only within the internal hole of the torus. Probably a big difference between these two configurations. Regards Steven Vincent Johnson www.OrionWorks.com www.zazzle.com/orionworks
