I just came to the realization that most of the demonstrations that Russ has performed do not show much real work output. The piston is driven upward by the spark activated mixture, but then returns to the starting point. Any work done on the mass of the piston is returned back to the gas when it retracts for a net of zero. On occasions I have seen him toss items into the air which intercept his fan or ceiling, but the mass is small and little damage appears to be caused by the projectile.
It is going to be difficult to get accurate measurements for a valid determination of energy released unless that energy remains stored somewhere and compared to the electrical input.

However, I'm also free to note that trying to figure out what is going on with Russ's popper, when we have just about zero information about anything unusual happening, it like trying to see what is in a closed black box in a coal mine at midnight. And no light. What's in there? *Anything* could be in there. Boo! If Russ really wants to do something useful, he can start measuring the work done by that piston. It should be simple to do. Since it is reported that the thing doesn't heat up, no calorimetry is necessary, at least not yet. One regular characteristic of Papp engines is that they reportedly don't generate much, if any, heat. Just, allegedly, work. Okay, how much work with hou much energy input. A popper is perfect for testing this, avoiding all the complications of cycling engines. If there is no excess power in a single cycle, why would we even be interested in seeing if power can be sustained?
