Dielectric High Pressure Cavitation Cell by K-Fusion Technology, inc. (Republic of Korea)

Hi mkemp - welcome to the forum. Are you involved with this patent?

I'd just like to make a few comments.

Quote from section 0002

Plasma refers to a gaseous state which is separated into electrons (e-) with negative charges and ions (A+:
hydrogen atom nuclei) with positive charges at an ultra-high temperature. Further, the plasma also refers to a gas in
which particles with electricity are gathered. The plasma has a very high charge separation degree, but is electrically
neutral because the number of negative charges and the number of positive charges are totally the same. When a high
energy is applied to a gas in a molecular state, the gas is separated into electrons and atomic nuclei at tens of thousands
of °C to become a plasma state

The extract above seems to be describing a thermal plasma. Not all plasmas are thermal. Most plasmas that we we create are nonthermal. (e.g. in fluorescent lamps)

In a nonthermal plasma, the electron temperature and atom temperature are vastly different.

From what I can see, the images in the video just look like a classic vapour-shock nonthermal plasma, exhibiting a form of triboluminescence. e.g. If you spin a boat propeller fast enough, you get a similar light.

Quote from section 0218 (industrial applicability)

The submerged plasma generator according to the present embodiment and an application including the same may be used for a hydrogen gas generating system, a plasma activated water producing system, and an electric power generating system which generates electric energy.

There seems to be no claim that the "plasma" would generate more energy than would be consumed by the pump - so its use as an electrical generator would appear pointless.

It could conceivably be used to treat (sterilise) water, but there are already simpler electrical nonthermal plasma devices on the market that do that - and they do not suffer from cavitation erosion, which might affect this device.

As it has a submerged jet, then it may act a bit like a sonoluminescence device.

I see the older Korean patent application makes hydrogen fusion claims.

Interesting passage from end section of this paper:

The 2012 Plasma Roadmap

Quote

Conclusions. The plasma community is a rapacious user of atomic and molecular data but is increasingly faced with a deficit of data necessary to both interpret observations and build models that can be used to develop the next-generation plasma tools that will continue the scientific and technological progress of the late 20th and early 21st century. It is therefore necessary to both compile and curate the A&M data we do have and thence identify missing data needed by the plasma community (and other user communities). Such data may then be acquired using a mixture of benchmarking experiments and theoretical formalisms. However, equally important is the need for the scientific/technological community to recognize the need to support the value of such databases and the underlying fundamental A&M that populates them. This must be conveyed to funders who are currently attracted to more apparent high-profile projects.

Gills Aloud? Tiny fish found making very big noise

A miniscule, transparent fish makes drumming sounds as loud as a jackhammer, say researchers.

Their working hypothesis is that the fish are drumming on their swim bladder - but as the previous pistol shrimp example shows, that might be a bit too simplistic.
