Art collective Liberate Tate (www.liberatetate.org) has installed a massive 16.5 metre (40 foot), one and a half tonne wind turbine blade in Tate Modern’s Turbine Hall Saturday (7 July 2012) submitting the artwork to be part of Tate’s permanent collection.

The artwork, called ‘The Gift’, was installed in an unofficial performance involving over 100 members of the group that has become internationally renowned for artworks aimed at ending the relationship of Tate and other national cultural institutions with oil companies.
