Their brochure at https://ibispower.eu/wp-content/uploads/2021/04/Ibis-Power-Brochure-2021.pdf mentions two business cases with 132MWh/year for solar and 40 MWh/year for wind. So I'm really curious how they calculated that factor 6 to 10.
Furthermore the question is at what price they can market their solution. Normal wind turbines become more cost effective with larger turbine sizes hence the increase wing span over the last years. This design seems to work with relatively small turbines, which would not help the business case.

Nice, I’ve actually been saying this for a while. Skyscrapers are a great place to put some wind turbines and solar panels. Imagine if every building could become self sustaining like that in the future.

Wind turbines, maybe. Solar panels, no.
Transmission losses are low. The cost of installing and maintaining a panel 500ft in the air on top of/on the side of a skyscraper is not low.
Better to have two panels in a random field somewhere than pay twice as much to put one, expensive and inaccessible, on a high-rise. Most places have no shortage of unused space, so long as you're actually outside the city.

The "random fields" in the Netherlands are pretty precious. We don't have a lot of space left over. We gotta find ways to use the space that is already used for buildings

One place I think should have them is the rooftops for swimming pools. Often they are flat roofed and easily accessible.
Also a very good place for solar heating panels and air source heat pumps. If you are going to store future excess energy as hot water, that is a very good place to do it.

That's true, the problem is that the roof structures were not build with this in mind so often they are not strong enough to support such a weight. I think with new buildings they are setting requirements though

I don't know about that.
The weight of solar panels on my local swimming pool roof would be much lower than the weight of a heavy snowfall building up on the flat roof (originally I was studying structural engineering).
With rooftop installations there is also the possibility to place them in the locations where there is a higher degree of tolerance. Snow unfortunately builds up across the entire surface.
If course it is definitely something to be double checked on a case by case basis but I don't think solar panel weight would be a problem in every case.

I can hear pigeons walking over the roof of my flat even after trying to sound proof it with 10cm of mineral wool. I would be really interested in hothey dealt with the sound/vibrations of the windmills. Reserve the top floors for deaf ppl ?

Amazing. Someone's finally came up with an idea to make small swept-area vertical axis turbines even worse than they would be standing alone.
Which is to obstruct them with other small vertical axis wind turbines.

Super interesting indeed, would have loved to hear them in one of the videos.

The following submission statement was provided by /u/darth_nadoma:
PowerNEST is an integrated solar-wind electricity system for the high rise buildings (buildings with at least five floors) . It has already been installed in five projects across the Netherlands, IBIS power is currently working on installing these units on 12 more.
According to IBIS Power, the ready-made system may create 6 to 10 times more electricity than standalone rooftop solar.
