sm0key,it is not for me the point : OU ~ surplus output energy or not !

The lever effect is as same like a transmission/transformer step up or step down ratio effect,working with motors and generators the seconds need low rpm and this makes the use of motor-generator concepts expensive !

The given transmission ratio for a driving vehicle :

For 1 KW :

3000 RPM. 100 Euros

1500 RPM. 200 Euros

750 RPM. 400 Euros

375 RPM. 800 Euros

187,5 RPM. 1600 Euros

this list above are only the 1 KW generator part costs - fob factory-

+ electric motor costs + transmission gear

calculating then all the investment sum ( 2500 Euros per KW nominal and 0,7 KW net) and amortize for each KWh- electricity generation costs we get

5 Euro-cents/KWh ( 2500 x 0,125) / (8766 x 0,7) where 0,125 the then years amortization by 2,5% capial tax and 8766 the permanent work in hours per year and 0,7 the net KWh output ( generator less motor input and gear losses)

~ conventional wind generator and photovoltaic electricity KWh- costs with lower investment need

This are net production costs without " patent price leverage" : typical factor ~ 6 times the production costs

Nobody in industry will invest in a 30 Euro-cents/KWh motor-generator marketing concept, specially in this case without patent rights safety !

Only when in future the EZB will inflationate by helicopter-money the energy market prices by 1000% and more !

A first physical and economical difference is to use higher rpm electric motors ( from grid- norm 3000 RPM/50Hz) to 6000 RPM/100 Hz or 12000 RPM/ 200 Hz and using 375 RPM ( by 6000 RPM motor )

or now " conventional small wind" 750 RPM ( by 12000 RPM motor) generator which let us get the total investment sum lower. !

Watching this"step down concept" like many others vids about OU or conventional energy transforming devices I do calculate the equipment costs per KWh-unit :

https://m.youtube.com/watch?t=64s&v=UukXtWSLnh8Near the 3 Eurocents/KWh by permanent work , only calculating with production costs : no profit diy project

The only worth of OU-devices is to generate elctricity/energy cheaply. ! The OU-effect by itself is worthless !

For me free wind-, free radiation-/free gravity-/free water force and free molecular/atomar forces and their to electricity conversion are "OU"-same. !

FREE = F UNITS ~ OU UNITS , free ~ temporarily unbonded ( Gibbs theorem)
