The team reckon that a flapping fin could be better than a propeller—possibly up to 20% more efficient over a broad range of speeds, according to some research. Whereas the whole surface of the ...

CAMBRIDGE, Mass--Inspired by the efficient swimming motion of the bluegill sunfish, MIT researchers are building a mechanical fin that could one day propel robotic submarines. The propeller-driven ...

Inspired by the efficient swimming motion of the bluegill sunfish, MIT researchers are building a mechanical fin that could one day propel robotic submarines. Propeller-driven submarines, or ...

The thrust generated by this fin is three times as energy efficient as the propeller installed in a small boat. The operation test in the sea starts around 26 seconds of the movie.
