Good find. Seems there's a lot out there. I don't have river in my garden but an unlimited supply of water.. hydro coupled to wind. Pump water uphill at night?

Micro n-blade turbines, n = 3,5.7,9,11 rpm vs torque? Time to review boundary layer theory.

One aspect that would might want to consider is the requirements to be able to sell power back to the grid and achieve the feed-in-tarriff.
Don't know about in your proposed location (NLD?) but for domestic sized production there can be annoying barriers.
Storage (e.g. Powerwall) is expensive.

Actually, in this case i'm referring to my cottage in hiils on east coast of IRL. I think I would have a snowball's chance in hell of getting a wind turbine on my roof in NL. There is a special commitee that decides on this and related matters.

I am just wondering why all the hullabaloo about solar panels and none about turbines, especially along the western seaboard of Ireland.

Historic 400 year-old mill. Yet another reason to ban fireworks.
Mayhem..

5 orangutans, a silverback gorilla, a chimp and several monkeys from Krefeld zoo might have agreed with that sentiment.

Wow! They really lucked out on the fence height. I wonder if, after delivery, the truck had to back out.
