And that is, what I think is Rossi's biggest problem. Very showy, very secretive.
The explanation I've heard is that he has something which works (for some definition of works) but doesn't know how it works or why. And because of that he is walking around afraid that if too many details get out about how it works then someone smarter then him will jump in and patent/publish the why and then be forever known as the person who "invented" this technology.
I don't know if that is true, but listening to Rossi talk and what he has written it seems like it could be true.
But elephant in the room is that if you can produce a MW of usable energy out of this thing then why not run it 24/7 and generate your quarter million a year in revenue (pretty much any market will buy baseload power at $30/MWhr. Use your first quarter million to build another one in year two, then use the half million from year two to build two more for year 3 and use the million dollars you get in year 3 to build four more, and the two million dollars from year 3 to build 8 more. Etc. Easy to sell shares in a company that is doubling in revenue each year and will continue to do so until it reaches 25% of baseload power (1TW or about a billion a year in revenue).
Either way, the way in which Rossi's e-cat story is playing out it screams hoax not breakthrough. That has nothing to do with the "reputation" of cold fusion and everything to do with the difference between seeing breakthroughs get promoted and hoaxes get promoted.
