Our reactor has both internal and external heating. Operating in the air can be also considered as load.
Daniel_G's reactor will require either secondary heating or adjustable load. With adjustable load they can keep reactor power constant.
The problem with published Mizuno reactor design is it reacts extremely to the load.
What we found is that the reason why internal heating is significantly better (if load is low) that for reaction itself the temperature difference must be present inside the cell. Temperature difference will cause gas to move. In the similar way as a wind is created in the air.The same thing will happen with Daniel_G's reactor even if it has very different shape.
If your reactor is smaller, similarly to Alan's, there is almost no temperature difference and possibility how the gas could circulate.
So the reactor design is extremely important. Including dimension. I appreciate that magicsound will try to modify his reactor.
On the other hand there are more ways to achieve what is needed. Rossi found it very soon.
But it all has to be properly dimensioned, including heater wattage and its size.
