It's an interesting concept, but if you have to spend a bunch of money up front to get the benefits of saving 11 gallons of diesel a day, the cost better be pretty low to make that a worthwhile investment. Long term I could see this catching on, but I can understand someone not wanting to be out of pocket a lot of money hoping to recoup the cost quickly enough.

One question not answered by the article:

Which is cheaper--burning diesel all night long, or plugging in? Obviously the cost of the former depends on the price of gas, but neither cost was mentioned in the article.

How about no chicken fried steak, gravy and potatoes until you plug your power cord in? I'm very familiar with power pedestals; the new ones in marinas have freshwater hook up, also. If my last marina had had power pedestals, instead of a shore based circuit panel, I might still be the owner of a 48' Christ Craft---instead of some mementos from the scrapping of said vessel following a fire.
