@axil: I won't comment your entire post as it would take ages and derail the thread, but if the point in LENR experiments is causing as much hydrogen as possible to desorb in large amounts from the active material and doing it continuously (ie having a flowing stream of hydrogen on it), then a possible way for achieving this could be doing it by mechanical means. A modified piston engine (for example from an air compressor) with the active powder or pellet located on the cylinder head could therefore work.
I guess this would make the experiment closer to a Papp engine.
@ogfusionist: and this would likely also work for the Al2O3-NiO supported nanocatalyst you've often suggested employing.
It wouldn't be a very simple experiment however.
