Our innovation: a wind turbine that you neither see nor hear is profitable

How? By using helmotz-resonators

Patented
Acoustic enclosure for building-based high-efficiency wind turbines

Goal
Acoustic solution to noise problems (and consequently permit problems) for building-based wind turbines; also efficiency increase. Acoustic issues solved and high efficiency non-visible turbines (architectural freedom) =no permit issues!

Cost / Timeframe
Investment cost estimate development: 200.000 eur / development 1 year
