On the possibility of "dense helium" - shall we call it the "alpharino" ?
Helium, unlike hydrogen, will not diffuse through metals - so long as the metal is nonporous. The first step in densification is (probably) diffusion... but that problem may not be the end-of-story. Raney nickel for instance is porous enough to pass helium and is also is catalytic - as in the hydrino world of Randell Mills and his Rydberg values. If Va'vra is right about helium shrinkage then a few possibilities are opened up in the search for how that feat can be accomplished. An interesting experiment would simply look for anomalous heat as helium is pumped through a Raney nickel membrane.

One curious observation is that there are a few other atoms besides hydrogen which may 'densify' : Presumably the dense version would provide anomalous heat. Quote "Our calculation also shows that other fully ionized “small-Z atoms” can form small-radius atoms... This would create atoms, where one electron is trapped on a small radius, effectively shielding one proton charge of thenucleus,.." Comment/question: Doesn't this finding open up the possibility for extracting anomalous heat from Helium? There could be secondary advantages to using Helium over H - due to inertness leading to ability to reuse the gas over and over ... Is there any indication of a catalyst for forming dense helium ?? I don't know, but I have begun to wonder if frigorific radiation could play a role in forming such atoms. Also, for atoms below the ground state, I propose the term depressed atom. This would compliment the term excited atom for atoms above the ground state. Harry
