Why vertical-axis wind turbines

Vertical-axis wind turbines rotate around an upright axis. Their layout supports direct-drive generation near the base and a compact design for local energy production.

Lift and drag designs

The WM 25 kW and WM 1000 W use lift from three vertical wings. The smaller WM 100 W uses two drag blades.

Designed for disassembly

The larger models use recyclable aluminium wings, a glued laminated timber tower and a steel foundation on reusable soil screws.
