What’s the Yamato? Sounds like a combination of a yam and a tomato.
The Yamato was a WWII Japanese super-battleship. Weighed about 1/3 more than the US Iowa class battleships and carried larger guns (18" vs 16" for the Iowas). It was sunk late in the war on a suicide mission to disrupt the US invasion of Okinawa.
In the late 1960s/early 70s the Japanese produced an anime series called "Space Battleship Yamato", in which the sunken Yamato was refitted into an interstellar starship with a year-long mission of crossing the galaxy to retrieve a device capable of saving and restoring an Earth nearly destroyed by an alien invasion.
In the series, the Yamato was powered by something called a "Wave Motion Engine", which seems almost identical in concept to this prototype motor.
Incidentally, "Space Battleship Yamato" was dubbed into English and released in the US as an afternoon kids cartoon called "Starblazers."
Additionally, there have been multiple additional anime series (and one recent live-action movie) based on "Yamato." AND they recently rebooted the series to update the anime and the storyline so it will appeal to modern audiences. The 26 episodes of the new series
can be found here. It uses subtitles rather than dubbing, but for anyone who grew up with and loved Starblazers it really recaptures the experience of being a preteen again ...
