Anyhow .. Our turbo"s produces practically double !!!! more Betz(+-39%) than the most sophisticated "Savonius"(drag)VAWT

( +- 21 % Betz rentability)

The (lift) "Darrieus VAWT's " massively sold by the Chinese, are not an option because they require too much wind

(which we usually don't have !!)

They are not self-starting and are subject to immense material fatigue(spinning much too fast)

So Please !!!! Forget about these (less than 5% works !!)

but make no mistake ... ..energy from wind turbines is indeed 10 times cheaper(proven) than solar panels…

but... you need enough WIND !!!

even... you need less wind for our Superbooster….

still you need sufficient wind ! (at least 4,5 m/sec) to rentabilise your investment short term.

The PERFECT windmill should( in Betz theory) be able to produce Betz 58/59% .

But this has ever been achieved and probably never will

Our turbo's have the advantages, producing no sound and no resonance vibrations (on buildings and houses).

They avoid optical pollution (reflections). They are SAFE (no risk of degrading and fly-away wing blades etc)

and..most important.. they are MAINTENANCE FREE! (magnetical levitation)

and in case you're interested….they don't kill birds..

The life expectancy is estimated 3 x longer than HAWTs.

( 35 years…and more, due to the Stainless steel construction, no friction, no gears, monoblock turbine/generator and minimum material fatigue )

But…still...nobody can exceed the laws of physics !!!!! (only fools and idiots are trying that...)
