The buoyancy is due to the difference between the density of the surrounding medium and the density of the medium within the bubbles, and the difference between using hydrogen and deuterium in the bubbles sure DOESN'T make a factor of 2 difference in favor of hydrogen.
I think this is correct, on first impression..... I simply bought Kort's claim, it sounded reasonable. I didn't think it all the way through. But, again, I haven't examined this closely...
