Thanks for posting Joe, entertaining as usual although can't imagine it surviving too long however good the software is. but got to give em credit for all the same.
I've copied the link below emailing me with offers on Skywinds product and going to look seriously at it.
While it's list price is around £2.5k it's being offered around the £1.5k mark! They've been around a while.
Just wondered if anyone has got one or experience of it?
Saw that several days ago. Thought it possibly a good idea for some (if it wasn’t nicked overnight).
They also offer a higher rated(?) turbine for a permanent fixture. I didn’t see a price for that.
IMO, likely a better option to that skywind offering (skywind - high wind speed for rated output, seemingly quite likely to need those ‘spare’ blades and other options required).

Size matters with wind.
Elevation, ruggedness, swept area.
My experimental rule of thumb is if you can't build at least a 3m blade diameter at double the height of the nearby wind barriers don't bother.
PS Robert "charged" the car with the jackery battery..not the wind turbine output.

I particularly liked the rigidity given to the structure by the guy ropes and cargo straps. All tagged back to that wee plate.

My favourite part is "You can see the input on the little screen" @ 12mins30 (I'm actually impressed it's as high as it is )
Fluctuating around 40w.
I'm guessing it's a ~60 000Wh battery in the car...
Hrmmm how could you offset that on an electric vehicle with less palava?
Pick any one:
Use aero alloy rims.
Use lower rolling resistance tyres.
Close the window.
Empty the boot.
Tell your passenger to walk.
Turn off the air con.
Turn off the side marker lights.
Turn off the dome light.
Drive 5kmph slower.
Don't use the brakes.
Dim the centre console.
Use a solar panel instead.
Put the jackery in the boot and forget the turnip.

Even an non electrically minded dummy/newbie like myself can see this things a waste of raw material.
Would save the 41watts its producing by leaving the pile of carp on the merchants shelf.
Wonder how many people they have mugged and sold one to?
Kind of like the reverse of this emoji

Got to say when I first watched it, and mindful of the "tongue in cheek" presentation of it, I was reminded of some of the scrap heap challenge builds where unbalanced wobbly machines tried to stay together long enough to do the task required, Rob looked at home with it all

That was 41W peak probably 20W RMS and a cherry picked result for the camera at that.
The product is sponsership & adcents from youtube & patreon, not viable tech that benefits lives.
Seems like there's more snake oil than genuine goods on the market these days.
Suppose that's to be expected when the marketing budget is so often bigger than the R&D budget.

That was a great program Moxi, some of those, i shudder to call them 'machines', were amazing in their basic rawness and good amusing fun to watch whilst waiting for them to fail, but great entertainment.
A bit like the old classic A-Team builds - that cabbage firing van/tank conversion bursting out of the barn was a television gem.
Thought the producer was quite good on the spindly windmill video too - very easy on the ears as such with his style so kept you viewing. Job done.
All the wobble in the support structure, exagerated at the turbine end in the video had me chuckling and waiting for the self destruct.
