O2 Arena to install mini wind turbines that can harness even a breeze

Vertical turbine by developer Alpha 311 can spin from gentle air movement

The O2 Arena will soon use a new breed of vertical wind turbine" to generate its own clean electricity, after signing a deal with a startup firm that says its turbines will generate power even when the wind is not blowing.

The London landmark once known as the Millennium Dome will begin by installing 10 of the 68cm (27in) vertical turbines. The breezy conditions at the site on the River Thames will help generate enough clean electricity to power 23 homes.
