I think one got a better spark emersed in hydrogen or
other gasses than air but I am not sure exactly about that.

	One can certainly do that if you keep out the air or
oxygen, to be exact. Most gas stations have electric pumps
submerged in gasoline. There is no oxygen to ignite the gas so
the motor could short out and or heat up and nothing much more
than that would happen as long as the gasoline level in the tank
didn't get so low that the motor was peeking out above the
liquid. That could be very bad news.

	I think that Fessendon's voice transmitter actually
connected a carbon mike between the output of the generator and
the antenna.

	Remember that no amplifiers existed back then and people
were trying anything they could do backin those days and some of
it was flat crazy by our standards but it sort of worked.
