The guys who let a whole year slip by without asking where the heat exchanger was?
That is unfair to IH. They knew perfectly well there was no heat exchanger. They also knew there could not be 1 MW of heat coming from the machine. They did not make this information public until the lawsuit was filed, but they did tell me and others the gist of the situation during the 1-year test.
I am sure they told that British investor as well. Otherwise he would have sued them. The fact that there was no exchanger and no 1-MW heat source was immediately obvious to anyone who visited the site, as I believe the investor (or his representative) did. See the Murray letter for details.
