Nowhere do they tell you the expected output per leaf, just "up to" figures, that's the tell numbers are being fudged here...

From brochure :

"Producing   an   average   of   2400   kWh   annually,   depending   upon   its   loca-on"

That is average power of 277.7 W  for a tree of 8 meter diameter...  :-DD

It's always more efficient to build a large turbine instead of many small ones.
And cheaper too.  ::)

But as a art installation it looks cool.  :-DD

Someone:
The manufacturing is quite clever with the PCB integrated generators (commonly done for low cost motors) and the moulded plastic parts. It would have been interesting to experiment with a PCB inductions generator rather than the permanent magnets. Building these in volumes would be cheap and easy, it may well be a real innovation if you can add cheap wind generation capacity to the growing home DC infrastructure.

Again, 8 meter diameter, 270W average power (and that is as stated by them, with no number whatsoever to substantiate it..)
They don't even say what is power rating per individual microgenerator.. Not to mention, the tree will see only turbulence, even in good laminar wind, because of turbine interaction...

That is an art installation. I even like it as such, nice symbolism etc.. But as serious power generation device it's a joke..
