just to quote Larsen in his cite: - He criticize the ide that He4 is trapped, and an ad hoc excuse - he claims that some transmutation cycle produce much more coherent energry by He4 than DD fusion
you can fin their reasoning in http://www.slideshare.net/lewisglarsen/lattice-energy-llctechnical-overviewcarbon-seed-lenr-networkssept-3-2009 page 25+ with page 34 summarizing their interpretation of McKrubre results... they claim it works better than DD hypothesis+leak excuse. 2012/4/9 Abd ul-Rahman Lomax <a...@lomaxdesign.com> > At 12:31 AM 4/8/2012, mix...@bigpond.com wrote: > >> In reply to Abd ul-Rahman Lomax's message of Thu, 05 Apr 2012 11:34:24 >> -0500: >> Hi, >> [snip] >> >Widom-Larsen theory completely fails to explain the actual >> >experimental results of cold fusion experiments, particularly the PdD >> >reactions of the Pons-Fleischmann Heat Effect. >> >> Not that I'm a fan of WL :), but: >> >> D + e- => 2 n >> >> Pd106 + 2 n => Ru104 + He4 + 11.9 MeV >> > > What "experimental result" does this explain? > > Pd106 + 2 n would become Pd108, which is stable. > > > > Granted 11.9 MeV isn't 23.8 MeV, but it is about half, and I'm not >> convinced >> that the He4/heat ratio has been measured all that accurately. >> > > The problem, Robin: the difficulty in measuring helium release is in > capturing all the helium.
