Yes, thanks. I'm well aware of them. They are larger, much 
more expensive and less robust than I have in mind. Leave 
one of those to itself for 20 years and it would be most 
unlikely to be still operating. My chimney spindizzy has 
probably been running for 30 years and will probably last 
another 30. If it has had power generation capability it 
would probably still be working if properly built. The 
available power would be a small fraction of that from the 
smallest marine windmill.
