Can you imagine going out to the Reno races to watch the Unlimited class runs with all the heavy WWII iron flying by...silently

I didn't think so. Airplanes have always made noise that sounded like either a reciprocating engine or a turbine. No reason to remove that luster now. I don't like taking long extension cords to the flying field as well.
I was in a Portland , OR area hobby shop about a week ago when the owner made the announcement that glow fuel was being immediately placed on a day by day price structure. Seems glow fuel is now as volatile as gasoline where prices are concerned. I still glad a $4.00 gallon of gas will go a lot farther than an $18.00+ gallon of glow fuel.
