Interesting. Wonder if the scalloped outside of the cowling is another application of the whale fin "bumps" eg:

The company holds 70% of the market for motors used with automotive door mirrors, door locks, and air conditioning damper actuators.

RPMs geared waaay down, somehow.

Neat packaging, but it looks real slow and is not much more than a toy. A moderately fit person with a pair of good fins could outrun that easily. If it's intended for scuba the speed will be half that in the video thanks to drag from buoyancy jacket and air cylinder.

Audio seems mucked up on that vid. Rider position doesn't seem very hydrodynamic...
