I think the same about the other cells too.

Actually just water alone is exploded on contact with that plasma burst.

Robert Krupa has even ran an engine on 100:1 air/fuel mixture just to prove it could be done. Not for practical driving.

It has always been claimed that a lean mixture can't work but that is only if you're using a measly little spark...that won't release much from the fuel that is there but this big blazing plasma ball will certainly release more from the same amount.
