My First diy Vertical Wind Turbine

Thanks...I know you deal a lot so I am looking up upon your experience sharing...

I am toying at the moment as my end result is going to be a 5Kw system, like in the last video.

Here, today...
Ground Layout , I'm planning to install in the back garden, the house layout creates a wind tunnel that is strong enough to move trees and leaves when windy. Will be installed at the boundary of 3 gardens, higher than no more 5-10meters probable and neighbours are sweet, they know me as eco green warrior and I think they will let me alone. If issues, i will ask them to cut the high trees off their garden as that blocks the wind / air ventilation in my back garden...

Visual, i will try to build it from plastic transparent materials and not metal...that will reduce the "eye sore" and make it invisible as much is it can be. Challenge is to get the right plastic or pvc to bend to the necessary curvature of the wind caption cup.

Vibrations, the vawt are very soft in running and if you get the right parts, minimum noise. It will be plugged in to the ground with a two poles system, which inside the ground while other higher insert inside the main base and allow some insulation/protection for noise and vibrations while allowing me to adjust the height as much as I can without creating disturbance or safety issues.

Alternator, I have found online some guys built already a rotor /stator for a proper vawt. I hope to be able to understand each other... just going to ask them for a smaller version, up to 1kw probable. It comes with the magnets and coils, all made at home and already fitted on a proper mechanical stand mechanism. I can't be bothered to play with these and encapsulating them, too much physics going on and I lack of even necessary knowledge and tools /space to build it.

Output, if works as I want it, it will be connected 24/7 to a pre-heater cylinder,180L full with water that will be installed with a 24/48v immersion heater. It will take the cold water from a low 10ish and bring up as much as possible just before the flow enters the 300l solar heated cylinder. That's the plan for winter. Summer, probable keep the greenhouse ventilated...

First steps first...im looking for a personal weather station, so that I can monitor the wind directions and the speeds.
I guesstimate that will take me 3-6 months of study and graphs / reports.
found few online, one very nice and pro but not delivering to EU countries yet.
Others, are not compatible with the wireless GSM spectrum...

In meantime, found this video here that gives me "food for thought".
More information is at the website linked at the bottom of the clip.

Nice to see some experimentation.

There is a belief that vertical wind works well in built up conditions because it harnesses wind coming from all directions. That isn't quite true because the blade relies on having low pressure on one side and high pressure on the other to create "lift". Built up areas have turbulence that interferes with this. But worth trying all the same and I like their quick and easy blade construction in that video.

Correct … 100 % !

Please see the video below.
That is why I want to reproduce at a lower scale the big system from last video (similar with the middle one above)
I can guess that the speed of the system is going to be the same if I add extra cups BUT it will increase the drag force, the power to move from zero and keep rotating inertial a more powerful dual stack rotor/stator...

I can say is the ultimatum top level vawt beauty that I seen in the past 2 weeks since digging the online's underground .
