Would you buy a car that is worth 100 kW but then for some reason it does only the 25% of the work?
The energy harvested should be equal to the rated power of the turbine that you buy multiplied by the working time. It is not so: this ratio is much lower than one, the agencies monitoring renewable energies performances record a 0,25-0,30 on average.
The problem is the technological distance between machine (the turbine), expecting a regular flow, and Nature offering instead a variable flow where the machine is continuosly switched on and off, with a poor level of production.
Check it in the image on the side.
It’s the machine that needs to adapt to Nature, and not the way around!
This is how energy production will increase, and renewable sources will be an effective alternative to the carbon energy supply system.
This is how our patent was born: if one wants to rotate even with the feeblest wind, then the “merry-go-round” needs to be just as big as to start-up.
This is the variable inertia principle.
And it goes with the variable inclination of the blades: if you want to go by boat with the force of the wind, you have to adjust the sails with the pace, or you will not move from the port.
Our solution, Windcity, combines the two principles of inclination of the blades and of inertia: variable geometry for variable flows.
It is the only machine that does not have a single torque curve but has an entire family and is carried alone on the most convenient one, in a continuous natural dialogue with Nature.

We founded Windcity in June 2016. Within the team there are 5 functional areas: R&D, market development, finance and organization, production and communication. We are in a constantly evolving reality and we are currently engaged in several pilot projects.
