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.
