http://newenergytimes.com/v2/news/2010/SRI-Case-Repl/SRI-Case.shtml Has anybody ever noticed that 2 out of 3 runs that show 4He growth in the SRI Case replication show a peak and then a decrease in 4He? This is a helium leak-tight chamber. Where does the 4He go? Two explanations come to mind. 1) There is no such thing as "leak proof" for helium - in the ppb range, and that is why it is called leak-tight. A few ppb per week would be expected. 2) The measurement itself removes the "missing" helium which otherwise would be flat.
