Our Mission

Energies from a Variable Nature

Our products are inspired by an organic concept of knowledge: know-how is the foundational tool for action, but Technology today needs to be completed by knowing why we are making something that way. It is the Science behind.

It is the Responsibility Principle: with our actions and products, we shall hand a liveable Planet to the next generations. We chose to be a Responsible Research & Innovation Tech Company generating impact for sustainability. We design and build according to 2006/42/CE Directive harmonized with IEC 61400-2; we test any feature in our wind tunnel before commissioning.

The Problem

There is a desperate need for distributed energy production, global wind is increasing but conventional turbines perform poorly in urban windy locations: why?

The reason is simple: the wind has two souls, like all of us

a regular soul that blows at high altitude: predictable, laminar, with slow cycles of 12-24 hours
a turbulent soul found at low altitude, in the urban and suburban environment, only available in quick gusts of 3-5 minutes

Human kind only aimed at the simplest regular flow for wind turbines, so conventional designs perform poorly in the turbulent wind.

Our Solution

Passive Variable Geometry

Our patented Passive Variable Geometry, or PVG technology, allows the turbine to quickly adapt to natural changes in wind flows:

Adjusts the pitch angle of the blade as you do with sails, and at the same time:
Increase and decrease the turbine diameter as in a carousel. In a word: Self-adapting
As a result it’s 4 times faster to start !

How does PVG work?

Because it is quick to start, it generates wind energy from each gust of wind that otherwise would be lost. Consider how many gusts of 5 minutes there are in a day, and you will have total efficiency from a simple circular input

Our Artificial Intelligence comes at no energy costs, just from understanding Nature's Intelligence and always adapting to Change.
