Rossi may not want to do that until he's holding several international patents. May be a while, yet.
But that hasn't stopped him from demonstrating his device to qualified experts, who have all been allowed to do everything but open the device up to see what's inside.
Thus far, none of these observers has been able to debunk his claims of excess heat generation. To the contrary, they've all verified it.
As far as e-cat generating power in your basement, that's at least a decade or two away.
Seems to me that configuring this device for point-of-use application is the smallest of Rossi's hurdles. That's just text book engineering, as far as I can tell.
He could present a design tomorrow, and it could be a great design. It would still be a decade or two before regulators and insurance underwriters approve it for residential use.
It will need to be demonstrated as working safely for years in controlled commercial/industrial environments before it will be approved for home use.
