This tells us that LENR is slowly but surely entering mainstream physics. Excellent work here and again we see an improved understanding. Other projects claim to be much further along that this group but no matter.
What matters is dozens of groups sharing knowledge and advances. It is never easy and this one has been as hard as they come. We are locking up deuterium in crystalline structures and inducing close contact. That us actually a pretty hard way to go about it.
However for science mavens, let me present one key element. The coulomb barrier is a mathematical construct and assumes orthogonal continuity which ladies is rubbish. What actually produces the effect of orthogonal continuity is fast motion or vibrations between any two ions. Freeze one and things improve immensely. Slow the other down and reactions may well become possible along a lucky AXIS.
My Cloud Cosmology has no difficulty accounting for this phenomena.
