Wind Chimney

In the city, the wind is unstable in direction and intensity. To produce energy with a wind turbine is an aberration. The wind chimney produces energy because the buildings are obstacles to the wind.

Stirling Engine

The efficiency of the Stirling Engine in theory is identical to that of the Carnot cycle. In practice, it is far from being the case. Instead of optimizing the existing types of Stirling engines, a new type of Stirling engine has been analyzed and redesigned.

Active Lift Turbine

Considerable sums have been invested to optimize the wind turbines and obtain values close to the Betz limit. While taking the problem back to the base, it is a gain of more than 30% without any optimization.

Nano Trap

Marine biodiversity is endangered by the degradation of plastics into micro and nanoparticles. A solution as old as the world : evaporation. The Nano Trap is not a filter but a purifier..

eXeco association

eXeco's core aspirations are:

Reduce the impact of human activities by producing renewable energy locally with clean technologies;

To make the concept of the wind chimney available to as many people as possible;

To reinvest the distribution of the surpluses to the only profit of the development of the company, by privileging the R and D and the sustainable development.
