The good news is that E-Cat works. The bad news is that it emits crank rays.

Seriously, I have no idea if it works or not: Rossi is surely a crank of the first water, but so was Tesla - and there seem to be quite a few professionally qualified people who think he has something.

Anyway, the 28th will tell the tale, unless it doesn’t.
