Power to the people
Renewable
energy
Our windturbines can both be used for off-grid and on-grid use.
The Propel-E 450 is designed for charging lead-acid batteries. This means two 80Ah batteries can be charged in one day. This equals lighting up 14 energy saving lightbulbs burning 12 hours a day for the Propel-E 450 and burning two energy saving lightbulbs 12 hours a day for the Propel-E 50.
The Propel-E 3000 shines in on-grid use because excess energy can easily be sold to the grid. With a yearly production of 2400kWh at an average windspeed of 4m/s, it provides families and small companies with a substantial amount of electricity.
CRADLE TO CRADLE
Upcycled
With our windturbines, we reduce the waste problem step by step. Our windturbines are made from recycled plastics like PET or bioplastics like PLA. We are also migrating away from rare-earth magnets towards ferrite magnets. The Propel-E 450 already uses this technology. In this way we reduce the need for poluting mining practices and unhealtht labor conditions.

ULTRA-LIGHTWEIGHT
3D-printed
Through 3D-printing important components like our blades, we can further recude the total amount of material. It allows us to achieve a weight ratio of 0,45kg/liter, which makes us able to compete with lightweight wood like birch.
Furthermore, 3D-printing gives us total control over the infill of the part which makes allows us to only use material where the most forces comes together. This technique is called topology optimization.
