That hydrogen bottle weight is a good point. It has been discussed somewhere, but I do not remember was it here or elsewhere.
This means with certainty that figures were fabricated and also in rather poor manner. There was initially also wrong units used, that hydrogen quantity was in kilogramms instead of gramms. This kind of typo in units implies that figures were just put there without much of thinking. Certainly they were not measured! —Jouni On Nov 23, 2011 3:00 PM, "Gigi DiMarco" <gdmgdms...@gmail.com> wrote: > I don't know if it was already reported but I found some oddies in the > hydrogen consumption > > October 6th test, from Lewan's report > > Weight hydrogen bottle: > - before filling: 13606.4 grams > - after filling: 13604.9 grams > Total loaded: 1.5 grams > Pressure H2 Bottle: 55 bar Reduced: 15 bar > > October 28th test, from Fioravanti/Rossi's report > > - before filling: 13604.5 grams > - after filling: 13602.8 grams > Total loaded: 1.7 grams > > We can derive the following conclusions: > > - no intermediate experiments/tests have been made since 0.4 grams is > likely to be a leakage, unless a different vessel was used > > - almost same quantity of Hydrogen is needed for either 1 or 107 fat-cat > systems > > OR > > - Fioravanti & Rossi report misleading figures > > Since Rossi in his blog says that 18 kg are needed in 6 months to charge > the 1MW plant, 100 grams are needed in 1 day. > > > Giancarlo > >
