That experiment was discussed in the paper submitted by Hagelstein, McKubre et al to the DOE in 2004: http://www.lenr-canr.org/acrobat/Hagelsteinnewphysica.pdf They flushed helium out by simply desorbing and reabsorbing deuterium several times, by varying the cell current, which they reversed in the end to get all the D out. It seems to me that if they actually managed to extract all the helium this way, which their resulting Q value suggests (104±10 % of 23.8 MeV), the reaction can't possibly happen in the bulk. Not even subsurface. It has to happen exactly on the surface, with some (about half) of the produced helium nuclei going slightly subsurface. If the reaction itself was subsurface, surely about half of the produced helium couldn't be recovered without more radical means such as the one you suggested below. ... > 2.
