Question regarding D2 gas Purity.
Does anyone have any insight regarding the required purity of D2 for a Mizuno replication? My reason for asking is that, rather than bother with bottled D2, I'm going with a hydrogen generator. There is a minimum amount of liquid H2O or D2O required to partially fill the reservoir, and that minimum is about 1 liter.
The 1-liter D2O I purchased is specified to be 99% pure. Is this good enough? Would it be feasible to use a 50/50 mix of D2O and H2O?
In their Mizuno replication, Ramarao and colleagues from the Centre for Energy Research in Bangalore say that the excess heat they see is only marginally affected by switching from D2 to H2 inside the reactor.
Here is a video describing their results. Look particularly at the discussion of slide 10 at around 11:10 in the video.
P.S. You will note that, unlike Mizuno, the Ramarao group uses Samarium in their system. I have no idea if this is relevant to the question of D2 versus H2.
