IH likely had no intention of ever paying the $89 million irrespective of what happened after the second installment. Once they had the information from Rossi, there was absolutely zero incentive for them to pay, ever, whether they replicated "Rossi's" reactor, or not. That is Rossi's fault for failing to negotiate a better deal, and failing to insist that the $89 million be escrowed. But it also exposes character flaws on the part of those behind IH.
IH are clearly not telling you the whole story. In every instance of their "never substantiated" misdirection, the language of which extends into the Answer (albeit in a more wordy fashion), they left an escape hatch. The escape hatch is that they have a high-COP reactor, that they feel is no longer "Rossi's" technology, because they themselves did something to improve it. Every time they project the message that the "Rossi" technology does not work, they have left this escape hatch. It takes the form of words such as unable to replicate technology "directly" received from Rossi, or unable to replicate "using" Rossi's technology, and so forth. The fact that they filed their own national and international patent applications, with a co-inventor of their own, underscores this sneaky position.
And yes, they are sneaky. They word their messages in one way to misdirect the public into thinking one thing, while attempting to hide behind the curtain their true intentions. Their actions have the effect of damaging reputations of members of the LENR+ community, while they simultaneously pursue LENR+ for themselves. They have no love for the LENR (non LENR+ community). Whatever love you feel from them is a disingenuous.
