Hi, If Faux D masquerades as normal D, then a considerable proportion of heavy water may comprise Faux D. Therefore perhaps some of the CF experiments that only produce excess heat when using heavy water, do so, because of the relatively high Faux D content.
This is really just a "half formed" thought. I can't envisage the actual mechanism yet. Regards, Robin van Spaandonk http://users.bigpond.net.au/rvanspaa/ Competition provides the motivation, Cooperation provides the means.
