One method could be that in before summer demonstrations, there was thick wooden stand that could be hollow and hence store easily required amount of odorles ethanol. Fuel need was no more than few kilograms. And also it could provide sufficient supply for air or even compressed oxygen, to avoid incomplete burning. And if burning is catalyzed, it does not require that much room, and proper burning could easily be done in the core.
However, I do not say that it is easy and Rossi may require assistance from David Copperfield. We should understand that there are no limits how clever hoaxes people can construct. Therefore we should not underestimate those, although they are not relevant with this Rossi's case. Not anymore. What is most clever thing about Rossi that he performed demonstrations in such a way that they were clear for everyone open minded and who is motivated to go through them in detail at discussion forums, but they remained elusive for common people and for those who were basing their attitudes on prejudices against cold fusion. —Jouni On Oct 7, 2011 4:26 AM, "Jed Rothwell" <jedrothw...@gmail.com> wrote: > Someone wrote: > > > In previous experiments, however hidden energysources such as fuel >> > tanks were not excluded. > > > That is incorrect.
