One detail to add: If Rossi was a normal person pursuing normal investment opportunities, he would try to conduct a demo that was not readily open to such basic critiques. The demo might not convince skeptics, but it would be good enough to elicit from normal, intelligent people the question of "what should be done as a next step to look into this device's performance?" The unavoidable conclusion is that the demo did not clear this basic hurdle, but not for lack of opportunity. (See Alan F.'s response above.)
To the inevitable reply about protecting IP, sorry, this retort will be persuasive only to those who are already persuaded. But one can mention it anyway, and throw in the word "pathetic" as well, if it sounds good to one's ears.
Eric,
Well said, but (so far) our rather disappointing, and very subjective *reporter*, claims there were investors lined up waiting for a chance with the maestro.
