A Vertical Wind Turbine for Sailboat Masts

Ad 728×90
The beauty of sailboats is that they don't require power in order to move. However, modern-day sailboats have a host of onboard electronics that do require power: Navigation lights, radar, a VHF radio, a GPS unit, the navigation console, interior lighting.

These are typically powered by batteries, which are charged by an auxiliary motor if the boat has one, or the boat can be plugged in at the dock. However, a Belgian startup called Phileole has invented an alternative: This Grain Blanc wind turbine.

This can be bolted to the mast. Because of its vertical orientation, it can capture wind from any direction.
