I was surprised to find that it's a somewhat diverse team with a fair amount to lose if the paper turns out to be a fraud.

This leaves the last two possibilities:

- Rossi was somehow able to hoodwink fairly capable scientists (inject extra power into the E-Cat without them noticing),

- or he's actually built something interesting.

here is what I want to see. A double-blind experiment, where the suppliers provide the E-cat, sealed if need be. The testers will randomly supply the E-cat with either hydrogen gas (H2) or deuterium gas (D2), or deuterium hydride (DH). The magnitude of the measurable difference should suggest the likelihood of the process being nuclear.
