This kind of side-by-side comparison run should be extremely accurate - but the problem, HUGE problem, is that the "control" is nichrome, which could itself be active - in fact, quite active.
Typical composition of nichrome is 80% Ni, 20% Cr and in terms of Rossi's pronouncement, the control wire will probably have more Ni-62 than the constantan! Of course, they are not basing this on Rossi - but still it is a comparison run and you cannot ignore Rossi - so DO NOT use nickel in your control. That is almost a Doh! (slaps forehead) IMO if they will switch to something Kanthal resistance wire which is iron-chromium-aluminum alloy they will get MUCH better comparative results Jones -----Original Message----- From: Akira Shirakawa Harry Veeder wrote: http://www.quantumheat.org/index.php/en/follow/follow-4/271-s-g-cells-prelim inary-test-findings-for-run-2 Does anybody have any rough idea of what would the error margin be for an experiment arranged like what can be seen in the photos in the link above?
