But no one could do that at the time. Because a vortex like that is constantly moving around, it becomes incredibly complicated to pin down. It took me twenty years to figure out how to freeze a whirlpool/
But when I did, it allowed us to see that all movement of fluids can be described with one algorithm with four variables.”
This algorithm compared with the EE Biot-Savart law ? ( also called Ampére law or Laplace law)
https://worldwide.espacenet.com/publicationDetails/biblio?DB=EPODOC&II=2&ND=3&adjacent=true&locale=en_EP&FT=D&date=19850314&CC=DE&NR=3330899A1&KC=A1[0013]
This consists in the fact that an electromagnetic field around an arbitrarily bent wire-shaped conductor and a flow field around an arbitrarily shaped vortex thread are described by the same law, Biot-Savart's law.
The quantities "increase in magnetic field strength" and "increase in speed" therefore correspond to one another.
Since magnetic field strength can be concentrated by winding a current-carrying conductor into a coil, an increase in speed can also be achieved in fluid technology by winding a
vortex thread into a coil.
If you arrange several whibs rotating in the same direction so that their axes lie on a circle, they will rotate around the center of the circle as a result of mutual induction. ( artificial TORNADO)The induction increases with the number of vortices. The winding speed increases and the wedged threads approach the shape of closely spaced ring vortices. The velocity field that these ring vortices induce inside them creates the desired concentration effect.

The “wind” created by the High Velocity Fan blowing on the blades of the 750 Watt PMA cause the generation of
660 Watts of electricity to be produced each hour while the high velocity fan is consuming only
120 watts per hour. Those numbers mean that in 24 hours the Fanerator will produce about 15,840 watts, or 15.8 kilowatts.

To make this invention independent of wind power, it is worthwhile to generate
artificial airflow, since the convergent nozzle is able to increase the airflow kinetic energy by converting the air
internal energy into kinetic energy. It was shown that the amount of internal energy converted to kinetic energy was: 221.9 /-21.737 =
104.2 times the natural (wind) kinetic energy. Assuming a fan driven by electrical motor 528 having a nominal power of X Kilo- Watt. Further, assuming that the fan transfers 50% of the electrical power into kinetic energy and that the nozzle is only 80% isentropic due to turbulence and separation. Thus the steady state flow enters the inlet 510, has only about 30% X of Hie electrical energy invested by the electrical motor 528. However, in the throat, the kinetic energy could be increased 100 times (assuming throat area 1/10 of the inlet 510 area, thanks to the convergent nozzle action we get kinetic energy in the throat, which is 30 X, i.e. 30 times more than the energy invested.
If turbine 502 is 50% efficient, it provides 15X power and the net profit is 14X power. Thus we get an independent energy machine that generates more energy that it consumes all on the expense of air internal source of internal energy.Thus in arid areas where water is in demand this embodiment
could provide high quality water and electrical power.
The implementation of powered fan in the inlet could be used as home power station, public power stations that provide electrical power to the electrical grid and automobile engines. As for public power stations, since they already have steam facilities, the steam power could be used to drive the powered fan while the electrical generator provides electrical power to the grid.
For example, a private home device could use a small
50CM fan diameter while
the larger fan diameter is about 1 meters to provide about
7 kilowatt electrical power.

https://contest.techbriefs.com/2010/entries/sustainable-technologies/527the AirWatt power plant can usually run 24 hours per day in appropriate locations. AirWatt plants use atmospheric air as the heat source and evaporating water as the heat sink.
The average amount of water flowing through the turbines at Hoover Dam is about 500 cubic meters per second as it produces 550 MW of power.
If only one-tenth that much water were pumped out of Lake Mead to an AirWatt Power plant out in the desert, it could produce
6,300 MW (6.3 GW) of power.
That is over a thousand ( I mean to calculate over 100 times !) times as much power per gallon of water as the power output of Hoover Dam.6300/550 output x 500/50 water flow = 114,5https://www.ksl.com/article/40762388/utah-inventions-prueitts-computer-graphics-desalination-tankThis process creates sustainable energy—and more sustainably than solar power plants (which can only work when the sun is out) and convection towers (which need four times more water per megawatt, and energy is required to pump the water to the top.)
Unfortunately, no investors were willing to construct the prototype for the AirWatt.

The average water use for a nine-minute shower was measured to be 2.2 litres, which corresponds to a water flow of only 0.24 litres per minute. [6] The Canadian Minimum Housing Group developed and tested several mist showers and obtained a flow rate of 0.33 liters of water per minute. [7].
In both cases, swab tests of bacteria on the skin showed that mist showers clean the body just as well as a "normal" shower of the same duration – using 30 to 40 times less water.Jonas Görgen, a young designer who graduated from the Design Academy Eindhoven in 2019, became fascinated by the history of the mist shower and decided to build one himself. Compared to earlier mist showers, Görgen has improved the concept in two important ways. First, he developed a kit that can turn almost any shower into a mist shower with very little effort. Second, in contrast to earlier experiments, his mist shower uses not one but three to six nozzles. This turns a functional but very basic mist shower (using only one nozzle), into a pleasant experience that feels just as comfortable and invigorating as a "normal" shower.
https://www.lowtechmagazine.com/2019/10/mist-showers-sustainable-decadence.htmlThe energy use of a mist shower could be further reduced by showering in an enclosed cabin, which increases thermal comfort with lower water temperatures. Another trick to increase thermal comfort in winter is to open the nozzles a bit so that the surface area of the water decreases. This increases water use but decreases heat loss. It is down to the individual to find balance between saving energy or water, based on local circumstances.
An argument that is often made against water saving shower heads is that people compensate lower water flows by taking longer showers. A similar argument could be made against mist showers, because the use of mist increases the time needed to rinse the body of soapy water.
However, a mist shower of 8.9 minutes offers plenty of time to get rid of soap and shampoo. The test subjects in the NASA experiments all managed to wash and rinse within 9 minutes, using only one nozzle on a flexible hose. Washing long hair is more problematic, but also in this case the problem can be addressed by opening the nozzles a bit more, increasing the water flow.
