I also think having a giant reciprocating mass, with an angular velocity exceeding 300 km/h would create a number of harmonic imbalances in the input shaft. The blade is enormous & what is the counter balance for it?
Those bearings & thrust bearing would have to sustain prolonged torsional forces...& then they take out say an eagle & that impact would resonate through the structure..not much required to put them out of balance...on going maintenance.
The solution make them bigger???
The Haliade-X offshore turbine features has a 220-meter rotor, a 107-meter blade, in 248 metres high.
The tower that hold is has 130tonnes of steel, the rotors weight 37 tonnes & the Nacell 67 tonnes.
67 tonnes on top of a 248 m tower......how big is the supports required to hold this in place?...
Think of the amount of CO2 front loaded into the atmosphere to manufacture & get operational.
Now imagine another 1.5 million of them on a ongoing maintenance roster or manufacturing & replacement....
Not to mention the amount of SF6 to keep the m cool.
and we need 1,490,000 might potentially supply the world power.....only to be replaced within 20 years.
The one inthe ocean , will never be dismantled, they will just fall into ocean, creating another clean up headache for the tax payer to foot as the companies will be long gone.
