Hi Brian,
You are correct in that Tesla's submarine (it was a boat that could sink
below the water and rise above it), was battery powered and wirelessly
controlled. It had compressed air motors, too. The wireless signal was used
only to remotely operate the submarine.
My error lies in the ambiguously worded introduction by the Sunday Journal
article author who stated, "The power to do this will be the electric
vibrations of the air used in wireless telegraphy." It is apparent from the
full content of the article that Tesla's submarine was, indeed, powered by
onboard power storage.

Probably other people have made the same mistake.
