Last year, GE and vertical axis wind turbine company Urban Green Energy announced the launch of the Sanya Skypump, a wind-powered charging station capable of recharging an electric car on wind energy alone.
Almost a year later, the two firms have just announced the official unveiling of the first Sanya Skypump to be installed in the world.
Located in Barcelona, Spain, the 4-kilowatt wind turbine looks like any other vertical axis wind turbine from a distance.
Get closer however, and you notice an electric car charging station neatly enclosed in the base of its 42-foot tower.
Although the turbine itself will generate electricity at wind speeds greater than 7 mph, it does need wind speeds of around 24 mph before it is generating 3 kilowatts, the power generally needed for the slowest level 2, 240-volt charging station.
At lower wind speeds, or higher level 2 charging loads, the Sanya Skypump can be connected to the grid to pull additional energy as required.
This makes it possible for the wind-powered charging station to offer up to 40 amps -- around 9 kilowatts -- of level 2 charging capability, despite a rated maximum wind turbine power output of 4 kilowatts.
Although the first to be installed since its launch, the Spanish Sanya Skypump won’t be the last.
