Pretty cool, quieter and cheaper than the big guys you see around. Is this the same effect used to propel the Calypso sail vessel?

Build your own.
I've actually been planning on building a VAWT for a few years- I have a Fisher and Paykel motor that I originally planned on rewiring into a single phase, 7 pole design but a recent youtuber I found has detailed videos on why they're actually not a good option versus winding your own design or altering other existing motors. My hope is my city won't know what the hell it is so they won't ever fine me for having it lol
VAWTs have some interesting use cases; they physically can never reach the generation of typical bladed turbines, but they produce far more "consistent" power at lower speeds regardless of wind direction. With low speeds and wide blades they don't chop wind so they're much quieter, and with rotating on a single axis they don't have near the same shaking or suspension needs- there's little groups of weird college kids everywhere like myself, that think you could have common home wind generators by installing them on top of ex-chimneys.
Here's the design and build of TheBackShed's LENZ2 VAWT Turbine. He was using it as a water pump on his off-grid property up in Canada.
Yep, they're just over 100 years old:

The Tulip Generator is just a prettier and trendier version. The Calypso's sails were vertical Magnus effect rotors, which are also a kind of vertical wind turbine, but not similar in any other way:
