When the load of a crane is descending or when a full lift of people goes down to the ground floor, a lot of energy is used to brake the descent energy. Green Line created a system that allows you to tap this energy to generate electricity, eliminating this waste.

We design and produce coreless axial flux electric generators with very high efficiency. Our generators are used on all our products but are also sold to other wind and hydro turbine manufacturers and for many other applications

We produce small and very small vertical axis wind turbines from 20 to 500W. Our turbines have several applications from home generation to radio/tv repeating stations and sailboats.

We design and produce small Crossflow and Pelton hydroelectric generators up tu 10 kW for drops from 5 to 200m. Our turbines are small and efficient thanks to the use of our coreless axial flux generators.
