The density for the Li-Al-H in the HUG report seems low to me. It will float on water. Check that density.

Here are the changes to the last values (first analysis): Free Volume for Gas: 1.09 ml --> 1.06 ml (not a large change) (Recall that Parkhomov estimates 2 ml in his experiment(s)) Weight Amount of Li(AlH4): 134 mg --> 19.7 mg (!!!!!!!) (Recall that Parkhomov/Translation states 100 mg) With these new values, the calculated pressure become approx. 1500 psi, which agrees with my calculation. But this new weight amount of Li(AlH4) is totally strange to me. The analysis goes on to state that this pressure is in line with Parkhomov's estimates, but as far as I understand, using far less Li(AlH4) than Parkhomov. The only value I have ever seen stated by Parkhomov is 100 mg, or a factor of 5 times more, by weight. Am I missing something here? This is a tremendous change that I'm having a hard time comprehending. I'm looking into the MFMP Calculation further, right now.

Although 0.0141 moles of Hydrogen are released, 0.00706 moles of Hydrogen Gas (H2) are released. I don't believe that free H atoms/ions contribute to the gas pressure in the free volume of the cell, and that the actual gas there is H2 Gas.
