Well - quantity does not make up for quality in this area. Just one claim well supported by a careful experiment would be highly interesting, and lead to replications. If real it would be headline news within 6 months.
Look at the MFMP signal. They thought that was real proof of nucelar activity: and had it been so they would have been able to replicate it and, again, headline news.
Well nothing in this world is certain, but IH say categorically that they cannot get it to work, and the other evidence all points the same direction (Rossi continually and egregiously having major errors in his test setups, even when $89M rest on them). So this is a fair working truth when posting here and speculating about this and that.
$89M is peanuts in comparison with the value of the technology. Therefore even though Rossi's involvement may be of limited use given his technical ineptitude, it would be well worth it to prevent legal issues. Indeed for them not to follow this license if Rossi's stuff did work would be negligent.
I beleive that your basic assumptions about the IH/Rossi relationship is wrong. It was Rossi who dumped IH. Rossi forced IH into their current situation. We know he dumped Defkalion, hydro fusion, now IH. Even IH knows that Rossi played them.
