We can exhaust the blade fans over the cycloidal wing to power the ring rotation.

with this given example values (from the above application )


However, this throughput rate should in no case exceed the volume.

Otherwise, the speed can be in the order of 3000 rpm.

This then results in peripheral speeds of the order of magnitude between 150 and 160 m / sec


the garden sprinkler work would have really a "Rasen sprengen"( 1:1 translation :  to blow up the lawn ) effect


" Rasen sprengen"  means " to water the lawn"

We could Triebflügel all the windmills and generate power when the weather is nice. One successful bench test of the 2 to 1 lift ratio of the prop ring would spawn a large after market add on sector within the windmill industry.

youtube : 30 US$ wind-turbine only mechanical output  https://www.youtube.com/watch?v=t9TrUPoevXI

This is the up to date build process for the OpenSourceLowTech.org $30 Lenz2 vertical axis wind turbine. The turbine can be made almost entirely from recycled materials with basic tools in six hours for $20-35. It is tested at [/font][/size]35-40% mechanically efficient, generates 130 watts mechanical in a 30 km/h wind, 1 kilowatt at 60 km/h, and can survive 100 km/h gusts.


Good/bad ? a.
Betz-limit : 59% conversion efficiency maximum



30 Km/h = 8.33 mtrs/sec. wind stream =  Beaufort scale 5 ,breeze

But compared mechanical to electrical power output,wind velocity related :



http://www.arestov.de/index.php/de/elektromotoren/windenergie




Example: A wind turbine with a nominal 400 W (manufacturer information) generated at a wind force of approx. 20 m / sec. an output of 70 watts.


After converting the generator to combined windings, the system was already delivering at a wind force of 5-6 m / sec. 140 watts. At 10-12 m / sec. were generated over 320 watts!

conventional     :        20 m/sec.         70 Watts      btw : 20 m/sec Beaufort 8/9 stormy wind/near storm velocity
double winding :   10-12 m/sec.        320  Watts

halve the wind velocity,more than 4 times the output


Comparing rotative movements from wind rotor with wheel revolutions from electric vehicles we see a great potential of brake energy recuperation gains !

The system (1) is designed to convert an asynchronous electric motor into an alternator of equivalent power or with characteristics superior to those to which the motor was designed.

The motor is rotated by mechanical drive system and by the addition of two capacitors it is converted into a two phase alternator.


All motors whether single, three or multiphase can be converted so as to produce two phase current.

All : also synchronous ?


which has to become tested,this " fine" claim    


asynchronous motors also called induction motors  https://en.wikipedia.org/wiki/Induction_motor

https://judbarovski.livejournal.com/tag/wind%20turbine


For example, an offshore wind farm of grid-type wind gearless turbines offered and dislocated along Mediterranean coast of Israel of 170 km width can produce at least
1.3 * 0.5 * (8 ^ 3) * 0.45 * 0.75 * 35 * 170,000 * 0.01 * 8600 = 57.5 milliard kWh electricity annualy by 0.1 US cent per kWh if 5 years payback.


I mean Mr.Judbarovski calculated wrong : instead 0,1 US cent = 1/10 cent  per KWh, right calculated : 1 US$cent per KWh


  calculating with his given 250 US$/KW windturbine price estimation ! And 5 years R.O.I. !

    Super-cheap Powerfull Wind Turbine Electricity, #2
while my turbine assembly provides 2000 kW, being about US$ 500,000.00 only, while the said Vestas is an order of magnitude expensive.

250 US$ /8766 hours(=permanent year)/5years(=R.O.I./pay back) = circa 0,57 cent/KWh : 100% full capacity/load condition


                                                                                                     + installation/over-head costs/maintenance

Offshore wind farms ( OWF ) are wind farms that are set up in the coastal area.


View of the offshore wind farm Riffgat northwest of the island of Borkum (the transformer platform on the left ) in light fogThe term "offshore wind farms", which is occasionally used in German for offshore wind farms, is wrong, however, as these have so far not been built on the " high seas ", but exclusively on the continental shelf . Offshore locations are usually characterized by relatively continuous wind conditions and high average wind speeds, which is why the wind turbines installed in them usually achieve a high utilization of 3500 to 5000 full load hours .

0,57 $cent/KWh /(5000 h practical load max /8766h theoretical full load )= 1,0 US$cent/KWh




US wind condition ,south coast ? $0,01/KWh-$0,015/KWh production costs  before tax credit ?
