The future of wind turbines? Bizarre-looking funnel produces SIX times more energy than traditional designs/Daily Mail

The Sheerwind Invelox turbine directs wind through a funnel
This wind is passed through a tube towards the turbine’s generator
The movement creates a ‘jet effect’ which increases the wind’s velocity
Sheerwind claims the turbine can work at speeds as low as 2mph
It produces 600% more electrical energy than commercial blade systems
It is scalable meaning smaller versions could be used in back gardens
